  • The Internet of Things Is Really the Internet of People

    - by HCM-Oracle
    By Mark Hurd - Originally Posted on LinkedIn As I speak with CEOs around the world, our conversations invariably come down to this central question: Can we change our corporate cultures and the ways we train and reward our people as rapidly as new technology is changing the work we do, the products we make and how we engage with customers? It’s a critical consideration given today’s pace of disruption, which already is straining traditional management models and HR strategies. Winning companies will bring innovation and vision to their employees and partners by attracting people who will thrive in this emerging world of relentless data, predictive analytics and unlimited what-if scenarios. So, where are we going to find employees who are as familiar with complex data as I am with orderly financial statements and business plans? I’m not just talking about high-end data scientists who most certainly will sit at or near the top of the new decision-making pyramid. Global organizations will need creative and motivated people who will devote their time to manipulating, reviewing, analyzing, sorting and reshaping data to drive business and delight customers. This might seem evident, but my conversations with business people across the globe indicate that only a small number of companies get it. In the past few years, executives have been busy keeping pace with seismic upheavals, including the rise of social customer engagement, the rapid acceleration of product-development cycles and the relentless move to mobile-first. But all of that, I think, is the start of an uphill climb to the top of a roller-coaster. Today, about 10 billion devices across the globe are connected to the Internet. In a couple of years, that number will probably double, and not because we will have bought 10 billion more computers, smart phones and tablets. This unprecedented explosion of Big Data is being triggered by the Internet of Things, which is another way of saying that the numerous intelligent devices touching our everyday lives are all becoming interconnected. Home appliances, food, industrial equipment, pets, pharmaceutical products, pallets, cars, luggage, packaged goods, athletic equipment, even clothing will be streaming data. Some data will provide important information about how to run our businesses and lead healthier lives. Much of it will be extraneous. How does a CEO cope with this unimaginable volume and velocity of data, much less harness it to excite and delight customers? Here are three things CEOs must do to tackle this challenge: 1) Take care of your employees, take care of your customers. Larry Ellison recently noted that the two most important priorities for any CEO today revolve around people: Taking care of your employees and taking care of your customers. Companies in today’s hypercompetitive business environment simply won’t be able to survive unless they’ve got world-class people at all levels of the organization. CEOs must demonstrate a commitment to employees by becoming champions for HR systems that empower every employee to fully understand his or her job, how it ties into the corporate framework, what’s expected of them, what training is available, and how they can use an embedded social network to communicate, collaborate and excel. Over the next several years, many of the world’s top industrialized economies will see a turnover in the workforce on an unprecedented scale. Across the United States, Europe, China and Japan, the “baby boomer” generation will be retiring and, by 2020, we’ll see turnovers in those regions ranging from 10 to 30 percent. How will companies replace all that brainpower, experience and know-how? How will CEOs perpetuate the best elements of their corporate cultures in the midst of this profound turnover? The challenge will be daunting, but it can be met with world-class HR technology. As companies begin replacing up to 30 percent of their workforce, they will need thousands of new types of data-native workers to exploit the Internet of Things in the service of the Internet of People. The shift in corporate mindset here can’t be overstated. The CEO has to be at the forefront of this new way of recruiting, training, motivating, aligning and developing truly 21-century talent. 2) Start thinking today about the Internet of People. Some forward-looking companies have begun pursuing the “democratization of data.” This allows more people within a company greater access to data that can help them make better decisions, move more quickly and keep pace with the changing interests and demands of their customers. As a result, we’ve seen organizations flatten out, growing numbers of well-informed people authorized to make decisions without corporate approval and a movement of engagement away from headquarters to the point of contact with the customer. These are profound changes, and I’m a huge proponent. As I think about what the next few years will bring as companies become deluged with unprecedented streams of data, I’m convinced that we’ll need dramatically different organizational structures, decision-making models, risk-management profiles and reward systems. For example, if a car company’s marketing department mines incoming data to determine that customers are shifting rapidly toward neon-green models, how many layers of approval, review, analysis and sign-off will be needed before the factory starts cranking out more neon-green cars? Will we continue to have organizations where too many people are empowered to say “No” and too few are allowed to say “Yes”? If so, how will those companies be able to compete in a world in which customers have more choices, instant access to more information and less loyalty than ever before? That’s why I think CEOs need to begin thinking about this problem right now, not in a year or two when competitors are already reshaping their organizations to match the marketplace’s new realities. 3) Partner with universities to help create a new type of highly skilled workers. Several years ago, universities introduced new undergraduate as well as graduate-level programs in analytics and informatics as the business need for deeper insights into the booming world of data began to explode. Today, as the growth rate of data continues to soar, we know that the Internet of Things will only intensify that growth. Moreover, as Big Data fuels insights that can be shaped into products and services that generate revenue, the demand for data scientists and data specialists will go on unabated. Beyond that top-level expertise, companies are going to need data-native thinkers at all levels of the organization. Where will this new type of worker come from? I think it’s incumbent on the business community to collaborate with universities to develop new curricula designed to turn out graduates who can capitalize on the data-driven world that the Internet of Things is surely going to create. These new workers will create opportunities to help their companies in fields as diverse as product design, customer service, marketing, manufacturing and distribution. They will become innovative leaders in fashioning an entirely new type of workforce and organizational structure optimized to fully exploit the Internet of Things so that it becomes a high-value enabler of the Internet of People.

  • Announcing: Improvements to the Windows Azure Portal

    - by ScottGu
    Earlier today we released a number of enhancements to the new Windows Azure Management Portal.  These new capabilities include: Service Bus Management and Monitoring Support for Managing Co-administrators Import/Export support for SQL Databases Virtual Machine Experience Enhancements Improved Cloud Service Status Notifications Media Services Monitoring Support Storage Container Creation and Access Control Support All of these improvements are now live in production and available to start using immediately.  Below are more details on them: Service Bus Management and Monitoring The new Windows Azure Management Portal now supports Service Bus management and monitoring. Service Bus provides rich messaging infrastructure that can sit between applications (or between cloud and on-premise environments) and allow them to communicate in a loosely coupled way for improved scale and resiliency. With the new Service Bus experience, you can now create and manage Service Bus Namespaces, Queues, Topics, Relays and Subscriptions. You can also get rich monitoring for Service Bus Queues, Topics and Subscriptions. To create a Service Bus namespace, you can now select the “Service Bus” tab in the Windows Azure portal and then simply select the CREATE command: Doing so will bring up a new “Create a Namespace” dialog that allows you to name and create a new Service Bus Namespace: Once created, you can obtain security credentials associated with the Namespace via the ACCESS KEY command. This gives you the ability to obtain the connection string associated with the service namespace. You can copy and paste these values into any application that requires these credentials: It is also now easy to create Service Bus Queues and Topics via the NEW experience in the portal drawer.  Simply click the NEW command and navigate to the “App Services” category to create a new Service Bus entity: Once you provision a new Queue or Topic it can be managed in the portal.  Clicking on a namespace will display all queues and topics within it: Clicking on an item in the list will allow you to drill down into a dashboard view that allows you to monitor the activity and traffic within it, as well as perform operations on it. For example, below is a view of an “orders” queue – note how we now surface both the incoming and outgoing message flow rate, as well as the total queue length and queue size: To monitor pub/sub subscriptions you can use the ADD METRICS command within a topic and select a specific subscription to monitor. Support for Managing Co-Administrators You can now add co-administrators for your Windows Azure subscription using the new Windows Azure Portal. This allows you to share management of your Windows Azure services with other users. Subscription co-administrators share the same administrative rights and permissions that service administrator have - except a co-administrator cannot change or view billing details about the account, nor remove the service administrator from a subscription. In the SETTINGS section, click on the ADMINISTRATORS tab, and select the ADD button to add a co-administrator to your subscription: To add a co-administrator, you specify the email address for a Microsoft account (formerly Windows Live ID) or an organizational account, and choose the subscription you want to add them to: You can later update the subscriptions that the co-administrator has access to by clicking on the EDIT button, and then select or deselect the subscriptions to which they belong. Import/Export Support for SQL Databases The Windows Azure administration portal now supports importing and exporting SQL Databases to/from Blob Storage.  Databases can be imported/exported to blob storage using the same BACPAC file format that is supported with SQL Server 2012.  Among other benefits, this makes it easy to copy and migrate databases between on-premise and cloud environments. SQL Databases now have an EXPORT command in the bottom drawer that when pressed will prompt you to save your database to a Windows Azure storage container: The UI allows you to choose an existing storage account or create a new one, as well as the name of the BACPAC file to persist in blob storage: You can also now import and create a new SQL Database by using the NEW command.  This will prompt you to select the storage container and file to import the database from: The Windows Azure Portal enables you to monitor the progress of import and export operations. If you choose to log out of the portal, you can come back later and check on the status of all of the operations in the new history tab of the SQL Database server – this shows your entire import and export history and the status (success/fail) of each: Enhancements to the Virtual Machine Experience One of the common pain-points we have heard from customers using the preview of our new Virtual Machine support has been the inability to delete the associated VHDs when a VM instance (or VM drive) gets deleted. Prior to today’s release the VHDs would continue to be in your storage account and accumulate storage charges. You can now navigate to the Disks tab within the Virtual Machine extension, select a VM disk to delete, and click the DELETE DISK command: When you click the DELETE DISK button you have the option to delete the disk + associated .VHD file (completely clearing it from storage).  Alternatively you can delete the disk but still retain a .VHD copy of it in storage. Improved Cloud Service Status Notifications The Windows Azure portal now exposes more information of the health status of role instances.  If any of the instances are in a non-running state, the status at the top of the dashboard will summarize the status (and update automatically as the role health changes): Clicking the instance hyperlink within this status summary view will navigate you to a detailed role instance view, and allow you to get more detailed health status of each of the instances.  The portal has been updated to provide more specific status information within this detailed view – giving you better visibility into the health of your app: Monitoring Support for Media Services Windows Azure Media Services allows you to create media processing jobs (for example: encoding media files) in your Windows Azure Media Services account. In the Windows Azure Portal, you can now monitor the number of encoding jobs that are queued up for processing as well as active, failed and queued tasks for encoding jobs. On your media services account dashboard, you can visualize the monitoring data for last 6 hours, 24 hours or 7 days. Storage Container Creation and Access Control Support You can now create Windows Azure Storage storage containers from within the Windows Azure Portal.  After selecting a storage account, you can navigate to the CONTAINERS tab and click the ADD CONTAINER command: This will display a dialog that lets you name the new container and control access to it: You can also update the access setting as well as container metadata of existing containers by selecting one and then using the new EDIT CONTAINER command: This will then bring up the edit container dialog that allows you to change and save its settings: In addition to creating and editing containers, you can click on them within the portal to drill-in and view blobs within them.  Summary The above features are all now live in production and available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using them today.  Visit the Windows Azure Developer Center to learn more about how to build apps with it. We’ll have even more new features and enhancements coming later this month – including support for the recent Windows Server 2012 and .NET 4.5 releases (we will enable new web and worker role images with Windows Server 2012 and .NET 4.5, and support .NET 4.5 with Websites).  Keep an eye out on my blog for details as these new features become available. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Oracle OpenWorld 2013 – Wrap up by Sven Bernhardt

    - by JuergenKress
    OOW 2013 is over and we’re heading home, so it is time to lean back and reflecting about the impressions we have from the conference. First of all: OOW was great! It was a pleasure to be a part of it. As already mentioned in our last blog article: It was the biggest OOW ever. Parallel to the conference the America’s Cup took place in San Francisco and the Oracle Team America won. Amazing job by the team and again congratulations from our side Back to the conference. The main topics for us are: Oracle SOA / BPM Suite 12c Adaptive Case management (ACM) Big Data Fast Data Cloud Mobile Below we will go a little more into detail, what are the key takeaways regarding the mentioned points: Oracle SOA / BPM Suite 12c During the five days at OOW, first details of the upcoming major release of Oracle SOA Suite 12c and Oracle BPM Suite 12c have been introduced. Some new key features are: Managed File Transfer (MFT) for transferring big files from a source to a target location Enhanced REST support by introducing a new REST binding Introduction of a generic cloud adapter, which can be used to connect to different cloud providers, like Salesforce Enhanced analytics with BAM, which has been totally reengineered (BAM Console now also runs in Firefox!) Introduction of templates (OSB pipelines, component templates, BPEL activities templates) EM as a single monitoring console OSB design-time integration into JDeveloper (Really great!) Enterprise modeling capabilities in BPM Composer These are only a few points from what is coming with 12c. We are really looking forward for the new realese to come out, because this seems to be really great stuff. The suite becomes more and more integrated. From 10g to 11g it was an evolution in terms of developing SOA-based applications. With 12c, Oracle continues it’s way – very impressive. Adaptive Case Management Another fantastic topic was Adaptive Case Management (ACM). The Oracle PMs did a great job especially at the demo grounds in showing the upcoming Case Management UI (will be available in 11g with the next BPM Suite MLR Patch), the roadmap and the differences between traditional business process modeling. They have been very busy during the conference because a lot of partners and customers have been interested Big Data Big Data is one of the current hype themes. Because of huge data amounts from different internal or external sources, the handling of these data becomes more and more challenging. Companies have a need for analyzing the data to optimize their business. The challenge is here: the amount of data is growing daily! To store and analyze the data efficiently, it is necessary to have a scalable and flexible infrastructure. Here it is important that hardware and software are engineered to work together. Therefore several new features of the Oracle Database 12c, like the new in-memory option, have been presented by Larry Ellison himself. From a hardware side new server machines like Fujitsu M10 or new processors, such as Oracle’s new M6-32 have been announced. The performance improvements, when using one of these hardware components in connection with the improved software solutions were really impressive. For more details about this, please take look at our previous blog post. Regarding Big Data, Oracle also introduced their Big Data architecture, which consists of: Oracle Big Data Appliance that is preconfigured with Hadoop Oracle Exdata which stores a huge amount of data efficently, to achieve optimal query performance Oracle Exalytics as a fast and scalable Business analytics system Analysis of the stored data can be performed using SQL, by streaming the data directly from Hadoop to an Oracle Database 12c. Alternatively the analysis can be directly implemented in Hadoop using “R”. In addition Oracle BI Tools can be used to analyze the data. Fast Data Fast Data is a complementary approach to Big Data. A huge amount of mostly unstructured data comes in via different channels with a high frequency. The analysis of these data streams is also important for companies, because the incoming data has to be analyzed regarding business-relevant patterns in real-time. Therefore these patterns must be identified efficiently and performant. To do so, in-memory grid solutions in combination with Oracle Coherence and Oracle Event Processing demonstrated very impressive how efficient real-time data processing can be. One example for Fast Data solutions that was shown during the OOW was the analysis of twitter streams regarding customer satisfaction. The feeds with negative words like “bad” or “worse” have been filtered and after a defined treshold has been reached in a certain timeframe, a business event was triggered. Cloud Another key trend in the IT market is of course Cloud Computing and what it means for companies and their businesses. Oracle announced their Cloud strategy and vision – companies can focus on their real business while all of the applications are available via Cloud. This also includes Oracle Database or Oracle Weblogic, so that companies can also build, deploy and run their own applications within the cloud. Three different approaches have been introduced: Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS) Using the IaaS approach only the infrastructure components will be managed in the Cloud. Customers will be very flexible regarding memory, storage or number of CPUs because those parameters can be adjusted elastically. The PaaS approach means that besides the infrastructure also the platforms (such as databases or application servers) necessary for running applications will be provided within the Cloud. Here customers can also decide, if installation and management of these infrastructure components should be done by Oracle. The SaaS approach describes the most complete one, hence all applications a company uses are managed in the Cloud. Oracle is planning to provide all of their applications, like ERP systems or HR applications, as Cloud services. In conclusion this seems to be a very forward-thinking strategy, which opens up new possibilities for customers to manage their infrastructure and applications in a flexible, scalable and future-oriented manner. As you can see, our OOW days have been very very interresting. We collected many helpful informations for our projects. The new innovations presented at the confernce are great and being part of this was even greater! We are looking forward to next years’ conference!

  • Integration Patterns with Azure Service Bus Relay, Part 3: Anonymous partial-trust consumer

    - by Elton Stoneman
    This is the third in the IPASBR series, see also: Integration Patterns with Azure Service Bus Relay, Part 1: Exposing the on-premise service Integration Patterns with Azure Service Bus Relay, Part 2: Anonymous full-trust .NET consumer As the patterns get further from the simple .NET full-trust consumer, all that changes is the communication protocol and the authentication mechanism. In Part 3 the scenario is that we still have a secure .NET environment consuming our service, so we can store shared keys securely, but the runtime environment is locked down so we can't use Microsoft.ServiceBus to get the nice WCF relay bindings. To support this we will expose a RESTful endpoint through the Azure Service Bus, and require the consumer to send a security token with each HTTP service request. Pattern applicability This is a good fit for scenarios where: the runtime environment is secure enough to keep shared secrets the consumer can execute custom code, including building HTTP requests with custom headers the consumer cannot use the Azure SDK assemblies the service may need to know who is consuming it the service does not need to know who the end-user is Note there isn't actually a .NET requirement here. By exposing the service in a REST endpoint, anything that can talk HTTP can be a consumer. We'll authenticate through ACS which also gives us REST endpoints, so the service is still accessed securely. Our real-world example would be a hosted cloud app, where we we have enough room in the app's customisation to keep the shared secret somewhere safe and to hook in some HTTP calls. We will be flowing an identity through to the on-premise service now, but it will be the service identity given to the consuming app - the end user's identity isn't flown through yet. In this post, we’ll consume the service from Part 1 in ASP.NET using the WebHttpRelayBinding. The code for Part 3 (+ Part 1) is on GitHub here: IPASBR Part 3. Authenticating and authorizing with ACS We'll follow the previous examples and add a new service identity for the namespace in ACS, so we can separate permissions for different consumers (see walkthrough in Part 1). I've named the identity partialTrustConsumer. We’ll be authenticating against ACS with an explicit HTTP call, so we need a password credential rather than a symmetric key – for a nice secure option, generate a symmetric key, copy to the clipboard, then change type to password and paste in the key: We then need to do the same as in Part 2 , add a rule to map the incoming identity claim to an outgoing authorization claim that allows the identity to send messages to Service Bus: Issuer: Access Control Service Input claim type: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier Input claim value: partialTrustConsumer Output claim type: net.windows.servicebus.action Output claim value: Send As with Part 2, this sets up a service identity which can send messages into Service Bus, but cannot register itself as a listener, or manage the namespace. RESTfully exposing the on-premise service through Azure Service Bus Relay The part 3 sample code is ready to go, just put your Azure details into Solution Items\AzureConnectionDetails.xml and “Run Custom Tool” on the .tt files.  But to do it yourself is very simple. We already have a WebGet attribute in the service for locally making REST calls, so we are just going to add a new endpoint which uses the WebHttpRelayBinding to relay that service through Azure. It's as easy as adding this endpoint to Web.config for the service:         <endpoint address="https://sixeyed-ipasbr.servicebus.windows.net/rest"                   binding="webHttpRelayBinding"                    contract="Sixeyed.Ipasbr.Services.IFormatService"                   behaviorConfiguration="SharedSecret">         </endpoint> - and adding the webHttp attribute in your endpoint behavior:           <behavior name="SharedSecret">             <webHttp/>             <transportClientEndpointBehavior credentialType="SharedSecret">               <clientCredentials>                 <sharedSecret issuerName="serviceProvider"                               issuerSecret="gl0xaVmlebKKJUAnpripKhr8YnLf9Neaf6LR53N8uGs="/>               </clientCredentials>             </transportClientEndpointBehavior>           </behavior> Where's my WSDL? The metadata story for REST is a bit less automated. In our local webHttp endpoint we've enabled WCF's built-in help, so if you navigate to: http://localhost/Sixeyed.Ipasbr.Services/FormatService.svc/rest/help - you'll see the uri format for making a GET request to the service. The format is the same over Azure, so this is where you'll be connecting: https://[your-namespace].servicebus.windows.net/rest/reverse?string=abc123 Build the service with the new endpoint, open that in a browser and you'll get an XML version of an HTTP status code - a 401 with an error message stating that you haven’t provided an authorization header: <?xml version="1.0"?><Error><Code>401</Code><Detail>MissingToken: The request contains no authorization header..TrackingId:4cb53408-646b-4163-87b9-bc2b20cdfb75_5,TimeStamp:10/3/2012 8:34:07 PM</Detail></Error> By default, the setup of your Service Bus endpoint as a relying party in ACS expects a Simple Web Token to be presented with each service request, and in the browser we're not passing one, so we can't access the service. Note that this request doesn't get anywhere near your on-premise service, Service Bus only relays requests once they've got the necessary approval from ACS. Why didn't the consumer need to get ACS authorization in Part 2? It did, but it was all done behind the scenes in the NetTcpRelayBinding. By specifying our Shared Secret credentials in the consumer, the service call is preceded by a check on ACS to see that the identity provided is a) valid, and b) allowed access to our Service Bus endpoint. By making manual HTTP requests, we need to take care of that ACS check ourselves now. We do that with a simple WebClient call to the ACS endpoint of our service; passing the shared secret credentials, we will get back an SWT: var values = new System.Collections.Specialized.NameValueCollection(); values.Add("wrap_name", "partialTrustConsumer"); //service identity name values.Add("wrap_password", "suCei7AzdXY9toVH+S47C4TVyXO/UUFzu0zZiSCp64Y="); //service identity password values.Add("wrap_scope", "http://sixeyed-ipasbr.servicebus.windows.net/"); //this is the realm of the RP in ACS var acsClient = new WebClient(); var responseBytes = acsClient.UploadValues("https://sixeyed-ipasbr-sb.accesscontrol.windows.net/WRAPv0.9/", "POST", values); rawToken = System.Text.Encoding.UTF8.GetString(responseBytes); With a little manipulation, we then attach the SWT to subsequent REST calls in the authorization header; the token contains the Send claim returned from ACS, so we will be authorized to send messages into Service Bus. Running the sample Navigate to http://localhost:2028/Sixeyed.Ipasbr.WebHttpClient/Default.cshtml, enter a string and hit Go! - your string will be reversed by your on-premise service, routed through Azure: Using shared secret client credentials in this way means ACS is the identity provider for your service, and the claim which allows Send access to Service Bus is consumed by Service Bus. None of the authentication details make it through to your service, so your service is not aware who the consumer is (MSDN calls this "anonymous authentication").

  • Per-pixel displacement mapping GLSL

    - by Chris
    Im trying to implement a per-pixel displacement shader in GLSL. I read through several papers and "tutorials" I found and ended up with trying to implement the approach NVIDIA used in their Cascade Demo (http://www.slideshare.net/icastano/cascades-demo-secrets) starting at Slide 82. At the moment I am completly stuck with following problem: When I am far away the displacement seems to work. But as more I move closer to my surface, the texture gets bent in x-axis and somehow it looks like there is a little bent in general in one direction. EDIT: I added a video: click I added some screen to illustrate the problem: Well I tried lots of things already and I am starting to get a bit frustrated as my ideas run out. I added my full VS and FS code: VS: #version 400 layout(location = 0) in vec3 IN_VS_Position; layout(location = 1) in vec3 IN_VS_Normal; layout(location = 2) in vec2 IN_VS_Texcoord; layout(location = 3) in vec3 IN_VS_Tangent; layout(location = 4) in vec3 IN_VS_BiTangent; uniform vec3 uLightPos; uniform vec3 uCameraDirection; uniform mat4 uViewProjection; uniform mat4 uModel; uniform mat4 uView; uniform mat3 uNormalMatrix; out vec2 IN_FS_Texcoord; out vec3 IN_FS_CameraDir_Tangent; out vec3 IN_FS_LightDir_Tangent; void main( void ) { IN_FS_Texcoord = IN_VS_Texcoord; vec4 posObject = uModel * vec4(IN_VS_Position, 1.0); vec3 normalObject = (uModel * vec4(IN_VS_Normal, 0.0)).xyz; vec3 tangentObject = (uModel * vec4(IN_VS_Tangent, 0.0)).xyz; //vec3 binormalObject = (uModel * vec4(IN_VS_BiTangent, 0.0)).xyz; vec3 binormalObject = normalize(cross(tangentObject, normalObject)); // uCameraDirection is the camera position, just bad named vec3 fvViewDirection = normalize( uCameraDirection - posObject.xyz); vec3 fvLightDirection = normalize( uLightPos.xyz - posObject.xyz ); IN_FS_CameraDir_Tangent.x = dot( tangentObject, fvViewDirection ); IN_FS_CameraDir_Tangent.y = dot( binormalObject, fvViewDirection ); IN_FS_CameraDir_Tangent.z = dot( normalObject, fvViewDirection ); IN_FS_LightDir_Tangent.x = dot( tangentObject, fvLightDirection ); IN_FS_LightDir_Tangent.y = dot( binormalObject, fvLightDirection ); IN_FS_LightDir_Tangent.z = dot( normalObject, fvLightDirection ); gl_Position = (uViewProjection*uModel) * vec4(IN_VS_Position, 1.0); } The VS just builds the TBN matrix, from incoming normal, tangent and binormal in world space. Calculates the light and eye direction in worldspace. And finally transforms the light and eye direction into tangent space. FS: #version 400 // uniforms uniform Light { vec4 fvDiffuse; vec4 fvAmbient; vec4 fvSpecular; }; uniform Material { vec4 diffuse; vec4 ambient; vec4 specular; vec4 emissive; float fSpecularPower; float shininessStrength; }; uniform sampler2D colorSampler; uniform sampler2D normalMapSampler; uniform sampler2D heightMapSampler; in vec2 IN_FS_Texcoord; in vec3 IN_FS_CameraDir_Tangent; in vec3 IN_FS_LightDir_Tangent; out vec4 color; vec2 TraceRay(in float height, in vec2 coords, in vec3 dir, in float mipmap){ vec2 NewCoords = coords; vec2 dUV = - dir.xy * height * 0.08; float SearchHeight = 1.0; float prev_hits = 0.0; float hit_h = 0.0; for(int i=0;i<10;i++){ SearchHeight -= 0.1; NewCoords += dUV; float CurrentHeight = textureLod(heightMapSampler,NewCoords.xy, mipmap).r; float first_hit = clamp((CurrentHeight - SearchHeight - prev_hits) * 499999.0,0.0,1.0); hit_h += first_hit * SearchHeight; prev_hits += first_hit; } NewCoords = coords + dUV * (1.0-hit_h) * 10.0f - dUV; vec2 Temp = NewCoords; SearchHeight = hit_h+0.1; float Start = SearchHeight; dUV *= 0.2; prev_hits = 0.0; hit_h = 0.0; for(int i=0;i<5;i++){ SearchHeight -= 0.02; NewCoords += dUV; float CurrentHeight = textureLod(heightMapSampler,NewCoords.xy, mipmap).r; float first_hit = clamp((CurrentHeight - SearchHeight - prev_hits) * 499999.0,0.0,1.0); hit_h += first_hit * SearchHeight; prev_hits += first_hit; } NewCoords = Temp + dUV * (Start - hit_h) * 50.0f; return NewCoords; } void main( void ) { vec3 fvLightDirection = normalize( IN_FS_LightDir_Tangent ); vec3 fvViewDirection = normalize( IN_FS_CameraDir_Tangent ); float mipmap = 0; vec2 NewCoord = TraceRay(0.1,IN_FS_Texcoord,fvViewDirection,mipmap); //vec2 ddx = dFdx(NewCoord); //vec2 ddy = dFdy(NewCoord); vec3 BumpMapNormal = textureLod(normalMapSampler, NewCoord.xy, mipmap).xyz; BumpMapNormal = normalize(2.0 * BumpMapNormal - vec3(1.0, 1.0, 1.0)); vec3 fvNormal = BumpMapNormal; float fNDotL = dot( fvNormal, fvLightDirection ); vec3 fvReflection = normalize( ( ( 2.0 * fvNormal ) * fNDotL ) - fvLightDirection ); float fRDotV = max( 0.0, dot( fvReflection, fvViewDirection ) ); vec4 fvBaseColor = textureLod( colorSampler, NewCoord.xy,mipmap); vec4 fvTotalAmbient = fvAmbient * fvBaseColor; vec4 fvTotalDiffuse = fvDiffuse * fNDotL * fvBaseColor; vec4 fvTotalSpecular = fvSpecular * ( pow( fRDotV, fSpecularPower ) ); color = ( fvTotalAmbient + (fvTotalDiffuse + fvTotalSpecular) ); } The FS implements the displacement technique in TraceRay method, while always using mipmap level 0. Most of the code is from NVIDIA sample and another paper I found on the web, so I guess there cannot be much wrong in here. At the end it uses the modified UV coords for getting the displaced normal from the normal map and the color from the color map. I looking forward for some ideas. Thanks in advance! Edit: Here is the code loading the heightmap: glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, mWidth, mHeight, 0, GL_RGBA, GL_UNSIGNED_BYTE, mImageData); glGenerateMipmap(GL_TEXTURE_2D); //glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR_MIPMAP_LINEAR); //glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); //glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); Maybe something wrong in here?

  • Screenshot Tour: Ubuntu Touch 14.04 on a Nexus 7

    - by Chris Hoffman
    Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like. We don’t recommend installing this yourself, as it’s still not a polished, complete experience. We’re using “Ubuntu Touch” as shorthand here — apparently this project’s new name is “Ubuntu For Devices.” The Welcome Screen Ubuntu’s touch interface is all about edge swipes and hidden interface elements — it has a lot in common with Windows 8, actually. You’ll see the welcome screen when you boot up or unlock a Ubuntu tablet or phone. If you have new emails, text messages, or other information, it will appear on this screen along with the time and date. If you don’t, you’ll just see a message saying “No data sources available.” The Dash Swipe in from the right edge of the welcome screen to access the Dash, or home screen. This is actually very similar to the Dash on Ubuntu’s Unity desktop. This isn’t a surprise — Canonical wants the desktop and touch versions of Ubuntu to use the same code. In the future, the desktop and touch versions of Ubuntu will use the same version of Unity and Unity will adjust its interface depending on what type of device your’e using. Here you’ll find apps you have installed and apps available to install. Tap an installed app to launch it or tap an available app to view more details and install it. Tap the My apps or Available headings to view a complete list of apps you have installed or apps you can install. Tap the Search box at the top of the screen to start searching — this is how you’d search for new apps to install. As you’d expect, a touch keyboard appears when you tap in the Search field or any other text field. The launcher isn’t just for apps. Tap the Apps heading at the top of the screen and you’ll see hidden text appear — Music, Video, and Scopes. This hidden navigation is used throughout Ubuntu’s different apps and can be easy to miss at first. Swipe to the left or right to move between these screens. These screens are also similar to the different panels in Unity on the desktop. The Scopes section allows you to view different search scopes you have installed. These are used to search different sources when you start a search from the Dash. Search from the Music or Videos scopes to search for local media files on your device or media files online. For example, searching in the Music scope will show you music results from Grooveshark by default. Navigating Ubuntu Touch Swipe in from the left edge anywhere on the system to open the launcher, a bar with shortcuts to apps. This launcher is very similar to the launcher on the left of Ubuntu’s Unity desktop — that’s the whole idea, after all. Once you’ve opened an app, you can leave the app by swiping in from the left. The launcher will appear — keep moving your finger towards the right edge of teh screen. This will swipe the current app off the screen, taking you back to the Dash. Once back on the Dash, you’ll see your open apps represented as thumbnails under Recent. Tap a thumbnail here to go back to a running app. To remove an app from here, long-press it and tap the X button that appears. Swipe in from the right edge in any app to quickly switch between recent apps. Swipe in from the right edge and hold your finger down to reveal an application switcher that shows all your recent apps and lets you choose between them. Swipe down from the top of the screen to access the indicator panel. Here you can connect to Wi-Fi networks, view upcoming events, control GPS and Bluetooth hardware, adjust sound settings, see incoming messages, and more. This panel is for quick access to hardware settings and notifications, just like the indicators on Ubuntu’s Unity desktop. The Apps System settings not included in the pull-down panel are available in the System Settings app. To access it, tap My apps on the Dash and tap System Settings, search for the System Settings app, or open the launcher bar and tap the settings icon. The settings here a bit limited compared to other operating systems, but many of the important options are available here. You can add Evernote, Ubuntu One, Twitter, Facebook, and Google accounts from here. A free Ubuntu One account is mandatory for downloading and updating apps. A Google account can be used to sync contacts and calendar events. Some apps on Ubuntu are native apps, while many are web apps. For example, the Twitter, Gmail, Amazon, Facebook, and eBay apps included by default are all web apps that open each service’s mobile website as an app. Other applications, such as the Weather, Calendar, Dialer, Calculator, and Notes apps are native applications. Theoretically, both types of apps will be able to scale to different screen resolutions. Ubuntu Touch and Ubuntu desktop may one day share the same apps, which will adapt to different display sizes and input methods. Like Windows 8 apps, Ubuntu apps hide interface elements by default, providing you with a full-screen view of the content. Swipe up from the bottom of an app’s screen to view its interface elements. For example, swiping up from the bottom of the Web Browser app reveals Back, Forward, and Refresh buttons, along with an address bar and Activity button so you can view current and recent web pages. Swipe up even more from the bottom and you’ll see a button hovering in the middle of the app. Tap the button and you’ll see many more settings. This is an overflow area for application options and functions that can’t fit on the navigation bar. The Terminal app has a few surprising Easter eggs in this panel, including a “Hack into the NSA” option. Tap it and the following text will appear in the terminal: That’s not very nice, now tracing your location . . . . . . . . . . . .Trace failed You got away this time, but don’t try again. We’d expect to see such Easter eggs disappear before Ubuntu Touch actually ships on real devices. Ubuntu Touch has come a long way, but it’s still not something you want to use today. For example, it doesn’t even have a built-in email client — you’ll have to us your email service’s mobile website. Few apps are available, and many of the ones that are are just mobile websites. It’s not a polished operating system intended for normal users yet — it’s more of a preview for developers and device manufacturers. If you really want to try it yourself, you can install it on a Wi-Fi Nexus 7 (2013), Nexus 10, or Nexus 4 device. Follow Ubuntu’s installation instructions here.

  • Entity Framework 6: Alpha2 Now Available

    - by ScottGu
    The Entity Framework team recently announced the 2nd alpha release of EF6.   The alpha 2 package is available for download from NuGet. Since this is a pre-release package make sure to select “Include Prereleases” in the NuGet package manager, or execute the following from the package manager console to install it: PM> Install-Package EntityFramework -Pre This week’s alpha release includes a bunch of great improvements in the following areas: Async language support is now available for queries and updates when running on .NET 4.5. Custom conventions now provide the ability to override the default conventions that Code First uses for mapping types, properties, etc. to your database. Multi-tenant migrations allow the same database to be used by multiple contexts with full Code First Migrations support for independently evolving the model backing each context. Using Enumerable.Contains in a LINQ query is now handled much more efficiently by EF and the SQL Server provider resulting greatly improved performance. All features of EF6 (except async) are available on both .NET 4 and .NET 4.5. This includes support for enums and spatial types and the performance improvements that were previously only available when using .NET 4.5. Start-up time for many large models has been dramatically improved thanks to improved view generation performance. Below are some additional details about a few of the improvements above: Async Support .NET 4.5 introduced the Task-Based Asynchronous Pattern that uses the async and await keywords to help make writing asynchronous code easier. EF 6 now supports this pattern. This is great for ASP.NET applications as database calls made through EF can now be processed asynchronously – avoiding any blocking of worker threads. This can increase scalability on the server by allowing more requests to be processed while waiting for the database to respond. The following code shows an MVC controller that is querying a database for a list of location entities:     public class HomeController : Controller     {         LocationContext db = new LocationContext();           public async Task<ActionResult> Index()         {             var locations = await db.Locations.ToListAsync();               return View(locations);         }     } Notice above the call to the new ToListAsync method with the await keyword. When the web server reaches this code it initiates the database request, but rather than blocking while waiting for the results to come back, the thread that is processing the request returns to the thread pool, allowing ASP.NET to process another incoming request with the same thread. In other words, a thread is only consumed when there is actual processing work to do, allowing the web server to handle more concurrent requests with the same resources. A more detailed walkthrough covering async in EF is available with additional information and examples. Also a walkthrough is available showing how to use async in an ASP.NET MVC application. Custom Conventions When working with EF Code First, the default behavior is to map .NET classes to tables using a set of conventions baked into EF. For example, Code First will detect properties that end with “ID” and configure them automatically as primary keys. However, sometimes you cannot or do not want to follow those conventions and would rather provide your own. For example, maybe your primary key properties all end in “Key” instead of “Id”. Custom conventions allow the default conventions to be overridden or new conventions to be added so that Code First can map by convention using whatever rules make sense for your project. The following code demonstrates using custom conventions to set the precision of all decimals to 5. As with other Code First configuration, this code is placed in the OnModelCreating method which is overridden on your derived DbContext class:         protected override void OnModelCreating(DbModelBuilder modelBuilder)         {             modelBuilder.Properties<decimal>()                 .Configure(x => x.HasPrecision(5));           } But what if there are a couple of places where a decimal property should have a different precision? Just as with all the existing Code First conventions, this new convention can be overridden for a particular property simply by explicitly configuring that property using either the fluent API or a data annotation. A more detailed description of custom code first conventions is available here. Community Involvement I blogged a while ago about EF being released under an open source license.  Since then a number of community members have made contributions and these are included in EF6 alpha 2. Two examples of community contributions are: AlirezaHaghshenas contributed a change that increases the startup performance of EF for larger models by improving the performance of view generation. The change means that it is less often necessary to use of pre-generated views. UnaiZorrilla contributed the first community feature to EF: the ability to load all Code First configuration classes in an assembly with a single method call like the following: protected override void OnModelCreating(DbModelBuilder modelBuilder) {        modelBuilder.Configurations            .AddFromAssembly(typeof(LocationContext).Assembly); } This code will find and load all the classes that inherit from EntityTypeConfiguration<T> or ComplexTypeConfiguration<T> in the assembly where LocationContext is defined. This reduces the amount of coupling between the context and Code First configuration classes, and is also a very convenient shortcut for large models. Other upcoming features coming in EF 6 Lots of information about the development of EF6 can be found on the EF CodePlex site, including a roadmap showing the other features that are planned for EF6. One of of the nice upcoming features is connection resiliency, which will automate the process of retying database operations on transient failures common in cloud environments and with databases such as the Windows Azure SQL Database. Another often requested feature that will be included in EF6 is the ability to map stored procedures to query and update operations on entities when using Code First. Summary EF6 is the first open source release of Entity Framework being developed in CodePlex. The alpha 2 preview release of EF6 is now available on NuGet, and contains some really great features for you to try. The EF team are always looking for feedback from developers - especially on the new features such as custom Code First conventions and async support. To provide feedback you can post a comment on the EF6 alpha 2 announcement post, start a discussion or file a bug on the CodePlex site. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Sending notification after an event has remained open for a specified period

    - by Loc Nhan
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Enterprise Manager (EM) 12c allows you to create an incident rule to send a notification and/or create an incident after an event has been open for a specified period. Such an incident rule will help prevent premature alerts on issues that may correct themselves within a certain amount of time. For example, there are some agents in an unstable network area, and often there are communication failures between the agents and the OMS lasting three, four minutes at a time. In this scenario, you may only want to receive alerts after an agent in that area has been in the Agent Unreachable status for at least five minutes. Note: Many non-target availability metrics allow users to specify the “number of occurrences” or the number of consecutive times metric values reach thresholds before a notification is sent. It is best to use the feature for such metrics. This article provides a step-by-step guide for creating an incident rule set to cater for the above scenario, that is, to create an incident and send a notification after the Agent Unreachable event has remained open for a five-minute duration. Steps to create the incident rule 1.     Log on to the console and navigate to Setup -> Incidents -> Incident Rules. Note: A non-super user requires the Create Enterprise Rule Set privilege, which is a resource privilege, to create an incident rule. The Incident Rules - All Enterprise Rules page displays. 2.     Click Create Rule Set … The Create Rule Set page displays. 3.     Enter a name for the rule set (e.g. Rule set for agents in flaky network areas), optionally enter a description, and leave everything else at default values, and click + Add. The Search and Select: Targets page pops up. Note:  While you can create a rule set for individual targets, it is a best practice to use a group for this purpose. 4.     Select an appropriate group, e.g. the AgentsInFlakyNework group. The Select button becomes enabled, click the button. The Create Rule Set page displays. 5.     Leave everything at default values, and click the Rules tab. The Create Rule Set page displays. 6.     Click Create… The Select Type of Rule to Create page pops up. 7.     Leave the Incoming events and updates to events option selected, and click Continue. The Create New Rule : Select Events page displays. 8.     Select Target Availability from the Type drop-down list. The page shows more options for Target Availability. 9.     Select the Specific events of type Target Availability option, and click + Add. The Select Target Availability events page pops up. 10.   Select Agent from the Target Type dropdown list. The page expands. 11.   Click the Agent unreachable checkbox, and click OK. Note: If you want to also receive a notification when the event is cleared, click the Agent unreachable end checkbox as well before clicking OK. The Create New Rule : Select Events page displays. 12.   Click Next. The Create New Rule : Add Actions page displays. 13.   Click + Add. The Add Actions page displays. 14.   Do the following: a.     Select the Only execute the actions if specified conditions match option (You don’t want the action to trigger always). The following options appear in the Conditions for Actions section. b.     Select the Event has been open for specified duration option. The Conditions for actions section expands. c.     Change the values of Event has been open for to 5 Minutes as shown below. d.     In the Create Incident or Update Incident section, click the Create Incident checkbox as following: e.     In the Notifications section, enter an appropriate EM user or email address in the E-mail To field. f.     Click Continue (in the top right hand corner). The Create New Rule : Add Actions page displays. 15.   Click Next. The Create New Rule : Specify name and Description page displays. 16.   Enter a rule name, and click Next. The Create New Rule : Review page appears. 17.   Click Continue, and proceed to save the rule set. The incident rule set creation completes. After one of the agents in the group specified in the rule set is stopped for over 5 minutes, EM will send a mail notification and create an incident as shown in the following screenshot. In conclusion, you have seen the steps to create an example incident rule set that only creates an incident and triggers a notification after an event has been open for a specified period. Such an incident rule can help prevent unnecessary incidents and alert notifications leaving EM administrators time to more important tasks. - Loc Nhan

  • Sonicwall VPN, Domain Controller Issues

    - by durilai
    I am trying to get the domain logon script to execute when I connect to VPN. I have a SonicWall 4060PRO, with the SonicOS Enhanced 4.2.0.0-10e. The VPN connects successfully, but the script does not execute. I am posting the log below, but I see two issues. The first is the inability to connect to domain. 2009/12/18 19:49:53:457 Information XXX.XXX.XXX.XXX NetGetDCName failed: Could not find domain controller for this domain. The second is the failure of the script. 2009/12/18 19:49:53:466 Warning XXX.XXX.XXX.XXX Failed to execute script file \DT-WIN7netlogondomain.bat, Last Error: The network name cannot be found.. I assume the second issue is caused because of the first, also on the second issue it seems to be trying to get the logon script from my local PC, not the server. Finally, the DC can be pinged and reached by its computer name once the VPN is connected. The shares that the script is tring to map can be mapped manually. Any help is appreciated. 2009/12/18 19:49:31:063 Information The connection "GroupVPN_0006B1030980" has been enabled. 2009/12/18 19:49:32:223 Information XXX.XXX.XXX.XXX Starting ISAKMP phase 1 negotiation. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX Starting aggressive mode phase 1 exchange. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX NAT Detected: Local host is behind a NAT device. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX The SA lifetime for phase 1 is 28800 seconds. 2009/12/18 19:49:32:289 Information XXX.XXX.XXX.XXX Phase 1 has completed. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX Received XAuth request. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX XAuth has requested a username but one has not yet been specified. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX Sending phase 1 delete. 2009/12/18 19:49:32:336 Information XXX.XXX.XXX.XXX User authentication information is needed to complete the connection. 2009/12/18 19:49:32:393 Information An incoming ISAKMP packet from XXX.XXX.XXX.XXX was ignored. 2009/12/18 19:49:36:962 Information XXX.XXX.XXX.XXX Starting ISAKMP phase 1 negotiation. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX Starting aggressive mode phase 1 exchange. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX NAT Detected: Local host is behind a NAT device. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX The SA lifetime for phase 1 is 28800 seconds. 2009/12/18 19:49:37:036 Information XXX.XXX.XXX.XXX Phase 1 has completed. 2009/12/18 19:49:37:094 Information XXX.XXX.XXX.XXX Received XAuth request. 2009/12/18 19:49:37:100 Information XXX.XXX.XXX.XXX Sending XAuth reply. 2009/12/18 19:49:37:110 Information XXX.XXX.XXX.XXX Received initial contact notify. 2009/12/18 19:49:37:153 Information XXX.XXX.XXX.XXX Received XAuth status. 2009/12/18 19:49:37:154 Information XXX.XXX.XXX.XXX Sending XAuth acknowledgement. 2009/12/18 19:49:37:154 Information XXX.XXX.XXX.XXX User authentication has succeeded. 2009/12/18 19:49:37:247 Information XXX.XXX.XXX.XXX Received request for policy version. 2009/12/18 19:49:37:253 Information XXX.XXX.XXX.XXX Sending policy version reply. 2009/12/18 19:49:37:303 Information XXX.XXX.XXX.XXX Received policy change is not required. 2009/12/18 19:49:37:303 Information XXX.XXX.XXX.XXX Sending policy acknowledgement. 2009/12/18 19:49:37:303 Information XXX.XXX.XXX.XXX The configuration for the connection is up to date. 2009/12/18 19:49:37:377 Information XXX.XXX.XXX.XXX Starting ISAKMP phase 2 negotiation with 10.10.10.0/255.255.255.0:BOOTPC:BOOTPS:UDP. 2009/12/18 19:49:37:377 Information XXX.XXX.XXX.XXX Starting quick mode phase 2 exchange. 2009/12/18 19:49:37:472 Information XXX.XXX.XXX.XXX The SA lifetime for phase 2 is 28800 seconds. 2009/12/18 19:49:37:472 Information XXX.XXX.XXX.XXX Phase 2 with 10.10.10.0/255.255.255.0:BOOTPC:BOOTPS:UDP has completed. 2009/12/18 19:49:37:896 Information Renewing IP address for the virtual interface (00-60-73-4C-3F-45). 2009/12/18 19:49:40:189 Information The virtual interface has been added to the system with IP address 10.10.10.112. 2009/12/18 19:49:40:319 Information The system ARP cache has been flushed. 2009/12/18 19:49:40:576 Information XXX.XXX.XXX.XXX NetWkstaUserGetInfo returned: user: Dustin, logon domain: DT-WIN7, logon server: DT-WIN7 2009/12/18 19:49:53:457 Information XXX.XXX.XXX.XXX NetGetDCName failed: Could not find domain controller for this domain. 2009/12/18 19:49:53:457 Information XXX.XXX.XXX.XXX calling NetUserGetInfo: Server: , User: Dustin, level: 3 2009/12/18 19:49:53:460 Information XXX.XXX.XXX.XXX NetUserGetInfo returned: home dir: , remote dir: , logon script: 2009/12/18 19:49:53:466 Warning XXX.XXX.XXX.XXX Failed to execute script file \DT-WIN7netlogondomain.bat, Last Error: The network name cannot be found..

  • Cisco ASA 5505 - L2TP over IPsec

    - by xraminx
    I have followed this document on cisco site to set up the L2TP over IPsec connection. When I try to establish a VPN to ASA 5505 from my Windows XP, after I click on "connect" button, the "Connecting ...." dialog box appears and after a while I get this error message: Error 800: Unable to establish VPN connection. The VPN server may be unreachable, or security parameters may not be configured properly for this connection. ASA version 7.2(4) ASDM version 5.2(4) Windows XP SP3 Windows XP and ASA 5505 are on the same LAN for test purposes. Edit 1: There are two VLANs defined on the cisco device (the standard setup on cisco ASA5505). - port 0 is on VLAN2, outside; - and ports 1 to 7 on VLAN1, inside. I run a cable from my linksys home router (10.50.10.1) to the cisco ASA5505 router on port 0 (outside). Port 0 have IP 192.168.1.1 used internally by cisco and I have also assigned the external IP 10.50.10.206 to port 0 (outside). I run a cable from Windows XP to Cisco router on port 1 (inside). Port 1 is assigned an IP from Cisco router 192.168.1.2. The Windows XP is also connected to my linksys home router via wireless (10.50.10.141). Edit 2: When I try to establish vpn, the Cisco device real time Log viewer shows 7 entries like this: Severity:5 Date:Sep 15 2009 Time: 14:51:29 SyslogID: 713904 Destination IP = 10.50.10.141, Decription: No crypto map bound to interface... dropping pkt Edit 3: This is the setup on the router right now.

  • OpenVPN on Ubuntu 11.10 - unable to redirect default gateway

    - by Vladimir Kadalashvili
    I'm trying to connect to connect to OpenVPN server from my Ubuntu 11.10 machine. I use the following command to do it (under root user): openvpn --config /home/vladimir/client.ovpn Everything seems to be OK, it connects normally without any warnings and errors, but when I try to browse the internet I see that I still use my own IP address, so VPN connection doesn't work. When I run openvpn command, it displays the following message among others: NOTE: unable to redirect default gateway -- Cannot read current default gateway from system I think it's the cause of this problem, but unfortunately I don't know how to fix it. Below is full output of openvpn command: Sat Jun 9 23:51:36 2012 OpenVPN 2.2.0 x86_64-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] [eurephia] [MH] [PF_INET6] [IPv6 payload 20110424-2 (2.2RC2)] built on Jul

  • Cisco ASA 5505 - L2TP over IPsec

    - by xraminx
    I have followed this document on cisco site to set up the L2TP over IPsec connection. When I try to establish a VPN to ASA 5505 from my Windows XP, after I click on "connect" button, the "Connecting ...." dialog box appears and after a while I get this error message: Error 800: Unable to establish VPN connection. The VPN server may be unreachable, or security parameters may not be configured properly for this connection. ASA version 7.2(4) ASDM version 5.2(4) Windows XP SP3 Windows XP and ASA 5505 are on the same LAN for test purposes. Edit 1: There are two VLANs defined on the cisco device (the standard setup on cisco ASA5505). - port 0 is on VLAN2, outside; - and ports 1 to 7 on VLAN1, inside. I run a cable from my linksys home router (10.50.10.1) to the cisco ASA5505 router on port 0 (outside). Port 0 have IP 192.168.1.1 used internally by cisco and I have also assigned the external IP 10.50.10.206 to port 0 (outside). I run a cable from Windows XP to Cisco router on port 1 (inside). Port 1 is assigned an IP from Cisco router 192.168.1.2. The Windows XP is also connected to my linksys home router via wireless (10.50.10.141). Edit 2: When I try to establish vpn, the Cisco device real time Log viewer shows 7 entries like this: Severity:5 Date:Sep 15 2009 Time: 14:51:29 SyslogID: 713904 Destination IP = 10.50.10.141, Decription: No crypto map bound to interface... dropping pkt Edit 3: This is the setup on the router right now.

  • Problem upgrading kernel on debian 3.1

    - by exhuma
    Hi, I have a quite old box in a remote server farm. So I have no direct access. Only remote SSH (and via SSH to a serial console). I haven't updated this box in ages. Now, whenever I want to install a new package, a dependency to glibc appears. Unfortunately, the install of glibc depends on a 2.6 kernel and I am running a venerable 2.4 kernel (one more reason to upgrade). The problem is, that the install of a new kernel has an indirect (over locales) dependency to glibc. So, to install glibc, I need a new kernel. For a new kernel, I need to upgrade glibc. Essentially I am blocked. What's the best way to proceed considering I have no "hardware" access? Here's a quick transcript of the upgrade process: [green:~]% sudo aptitude install linux-image-686 Reading Package Lists...

In that case, please add etch sources to your /etc/apt/sources.list and run: apt-get install -t etch linux-image-2.6 Then reboot into this new kernel, and proceed with your upgrade dpkg: error processing /var/cache/apt/archives/libc6_2.7-18lenny2_i386.deb (--unpack): subprocess pre-installation script returned error exit status 1 Errors were encountered while processing: /var/cache/apt/archives/libc6_2.7-18lenny2_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) Ack!

  • Connecting a LAN to an OpenVPN server via a windows 7 client gateway

    - by user705142
    I've got OpenVPN set up between my windows 7 client and linux server. The goal is that I'll get secure access to a webapp running on the server from any computer on the client LAN. I'm using ccd to assign static ip addresses to each client connection, with key authentication. It's working on my client machine (10.83.41.9), and when you go to the gateway IP address (10.83.41.1), it loads up the webapp. Now I really need the other computers on the client LAN to be able to connect to the webapp as well, via the windows machine. The client has a static IP address of 192.168.2.100 on the LAN, and I've enabled IP forwarding in windows (confirmed by ipconfig /all). In my router I've forwarded 10.83.41.1 / 255.255.255.255 to 192.168.2.100. In server.conf I have.. route 192.168.2.0 255.255.255.0 And in the office ccd.. ifconfig-push 10.83.41.9 10.83.41.10 iroute 192.168.2.0 255.255.255.0 The client log is as follows: Thu Mar 15 20:19:56 2012 OpenVPN 2.2.2 Win32-MSVC++ [SSL] [LZO2] [PKCS11] built on Dec 15 2011 Thu Mar 15 20:19:56 2012 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Thu Mar 15 20:19:56 2012 Control Channel Authentication: using 'ta.key' as a OpenVPN static key file Thu Mar 15 20:19:56 2012 Outgoing Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Incoming Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 LZO compression initialized Thu Mar 15 20:19:56 2012 Control Channel MTU parms [ L:1558 D:166 EF:66 EB:0 ET:0 EL:0 ] Thu Mar 15 20:19:56 2012 Socket Buffers: R=[8192->8192] S=[64512->64512] Thu Mar 15 20:19:56 2012 Data Channel MTU parms [ L:1558 D:1450 EF:58 EB:135 ET:0 EL:0 AF:3/1 ] Thu Mar 15 20:19:56 2012 Local Options hash (VER=V4): '9e7066d2' Thu Mar 15 20:19:56 2012 Expected Remote Options hash (VER=V4): '162b04de' Thu Mar 15 20:19:56 2012 UDPv4 link local: [undef] Thu Mar 15 20:19:56 2012 UDPv4 link remote: 111.65.224.202:1194 Thu Mar 15 20:19:56 2012 TLS: Initial packet from 111.65.224.202:1194, sid=ceb04c22 8cc6d151 Thu Mar 15 20:19:56 2012 VERIFY OK: depth=1, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 VERIFY OK: nsCertType=SERVER Thu Mar 15 20:19:56 2012 VERIFY OK: depth=0, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 Replay-window backtrack occurred [1] Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 1024 bit RSA Thu Mar 15 20:19:56 2012 [server] Peer Connection Initiated with 111.65.224.202:1194 Thu Mar 15 20:19:58 2012 SENT CONTROL [server]: 'PUSH_REQUEST' (status=1) Thu Mar 15 20:19:59 2012 PUSH: Received control message: 'PUSH_REPLY,route 10.83.41.1,topology net30,ping 10,ping-restart 120,ifconfig 10.83.41.9 10.83.41.10' Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: timers and/or timeouts modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: --ifconfig/up options modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: route options modified Thu Mar 15 20:19:59 2012 ROUTE default_gateway=192.168.2.1 Thu Mar 15 20:19:59 2012 TAP-WIN32 device [OpenVPN] opened: \\.\Global\{B32D85C9-1942-42E2-80BA-7E0B5BB5185F}.tap Thu Mar 15 20:19:59 2012 TAP-Win32 Driver Version 9.9 Thu Mar 15 20:19:59 2012 TAP-Win32 MTU=1500 Thu Mar 15 20:19:59 2012 Notified TAP-Win32 driver to set a DHCP IP/netmask of 10.83.41.9/255.255.255.252 on interface {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} [DHCP-serv: 10.83.41.10, lease-time: 31536000] Thu Mar 15 20:19:59 2012 Successful ARP Flush on interface [45] {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} Thu Mar 15 20:20:04 2012 TEST ROUTES: 1/1 succeeded len=1 ret=1 a=0 u/d=up Thu Mar 15 20:20:04 2012 C:\WINDOWS\system32\route.exe ADD 10.83.41.1 MASK 255.255.255.255 10.83.41.10 Thu Mar 15 20:20:04 2012 ROUTE: CreateIpForwardEntry succeeded with dwForwardMetric1=30 and dwForwardType=4 Thu Mar 15 20:20:04 2012 Route addition via IPAPI succeeded [adaptive] Thu Mar 15 20:20:04 2012 Initialization Sequence Completed From the other machines I can ping 192.169.2.100, but not 10.83.41.1.

Is there something I'm missing, or anything I should need to know?

  • Windows XP periodically disconnects, reconnects; Windows 7 doesn't

    - by einpoklum
    My setup: I have a PC with a Gigabyte GA-MA78S2H motherboard (Realtek Gigabit wired Ethernet on-board). I have the latest drivers (at least the latest driver for the NIC. I'm connecting via an Edimax BR-6216Mg (again, wired connection). For some reason I experience short periodic disconnects and reconnects. Specifically, Skype disconnects, tries to connect, succeeds after a short while; incoming SFTP sessions get dropped; using a browser, I sometime get stuck in the DNS lookup or connection to the website and a page won't load. A couple of seconds later, a reload works. All this happens with Windows XP SP3. With Windows 7, it doesn't happen. The connection is smooth (OS is sluggish though, but never mind that). Like I said, I updated the NIC driver. I tried reducing the MTU (used something called Dr. TCP), thinking maybe that would help, but it didn't. (I'm a bit but not super-knowledgeable about TCP parameters.) I'm guessing it's either a problem with the driver or some settings which are different between the two OSes. ipconfig for my adapter: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller Physical Address. . . . . . . . . : 00-1D-7D-E9-72-9E Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 192.168.0.2 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.0.254 DHCP Server . . . . . . . . . . . : 192.168.0.254 DNS Servers . . . . . . . . . . . : 192.117.235.235 62.219.186.7 Lease Obtained. . . . . . . . . . : Saturday, March 10, 2012 8:28:20 AM Lease Expires . . . . . . . . . . : Friday, January 26, 1906 2:00:04 AM

  • In Exim, is RBL spam rejected prior to being scanned by SpamAssassin?

    - by user955664
    I've recently been battling spam issues on our mail server. One account in particular was getting hammered with incoming spam. SpamAssassin's memory use is one of our concerns. What I've done is enable RBLs in Exim. I now see many rejection notices in the Exim log based on the various RBLs, which is good. However, when I run Eximstats, the numbers seem to be the same as they were prior to the enabling of the RBLs. I am assuming because the email is still logged in some way prior to the rejection. Is that what's happening, or am I missing something else? Does anyone know if these emails are rejected prior to being processed by SpamAssassin? Or does anyone know how I'd be able to find out? Is there a standard way to generate SpamAssassin stats, similar to Eximstats, so that I could compare the numbers? Thank you for your time and any advice.

  • My D-Link's Ethernet bridge downlink just got 10-30x slower?

    TL;DR: I unplugged my network to move my desk, and now downloading via my DIR-655's Ethernet LAN bridge is 10-30x slower than the Ethernet switch it's plugged into. Background My network is SMC cable modem <-> Cisco firewall <-> Netgear switch <-> D-Link WiFi† | | | | SMC8014 ASA-5505 GS608v2 gigE DIR-655 rev A3 gigE †The DIR-655 is used as an access point, not a router (although what D-Link calls an access point, I'd call a bridge). The "WAN" port is unused; the Netgear connects to the built-in 4-port Ethernet LAN switch, inside the built- in router/firewall. Endpoints: MacBook Pro 17" mid-2010 iPhone 4S Fedora 12 Linux server running reasonably fast dual-Athlon X2, VelociRaptors, etc. All cables are <10 feet, mostly CAT-5e, some CAT-6, all premade. All WiFi endpoints are within three feet of the D-Link. Yesterday I unplugged and rearranged stuff, and now connecting via the D-Link - even through the wired switch, right next to the incoming network cable - is 30x slower than connecting directly to the Netgear switch, on both my MacBook and iPhone. How I'm measuring "slower" I'm mostly using http://speedtest.net, which of course only really measures broadband speeds. I've also installed http://www.speedtest.net/mini.php on my local server, but can't test the iPhone with that. Results Speedtest.net, closest server over Comcast business-class: CONFIG | PING (ms) | DOWN (Mbps) | UP (Mbps) Mac <-> Ethernet <-> Netgear | 9 | 31.6 | 6.8 Mac <-> Ethernet <-> D-Link | 8 | 4.1 | 6.0 Mac <-> WiFi <-> D-Link | 9 | 1.4 | 2.9 iPhone <-> WiFi <-> D-Link | 67 | 0.4 | 1.6 Speedtest Mini on Linux PC: CONFIG | DOWN (Mbps) | UP (Mbps) Mac <-> Ethernet <-> NetGear | 97.2 | 76.9 Mac <-> Ethernet <-> D-Link | 8.2 | 24.2 Mac <-> WiFi <-> D-Link | 1.0 | 8.6 Slow typing in SSH: Mac <-> Ethernet <-> Netgear <-> Linux PC: smooth Mac <-> Ethernet <-> D-Link <-> Linux PC: choppy Note that D-Link upload speeds are normal on broadband, slower locally (but I'd believe that's a D-Link limitation), and always faster than the downloads! Since ssh is choppy just with slow typing, I don't believe it's a throttling-type problem either; that's not a lot of bandwidth. What I've tried Swapping all "good" and "bad" cables Re-plugging "bad" cable from D-Link to Netgear and watching it be the "good" cable pulling cables away from power lines Verify that the Mac auto-detects the D-Link as gigE Try to verify the link speed of the D-Link <- Netgear connection, but the firmware doesn't report that Verify that the D-Link sees no TX/RX errors or collisions Use different Ethernet ports on both Netgear and D-Link Reset the D-Link to factory settings Upgrade the D-Link firmware from 1.21 to 1.35NA, 2010/11/12, the latest Reboot everything at least once On the Mac, disable Wi-Fi during the Ethernet tests, and unplug Ethernet during the Wi-Fi tests Using iStumbler, verify that the D-Link isn't picking overloaded Wi-Fi channels (usually just 1-5 neighbors on my and adjacent channels, average for my apt building) Verify that the only client connected to the Wi-Fi was the iPhone Verify that nothing was being chatty on my network according to the WISH log Enable and disable all sorts of D-Link settings, including forcing WAN auto-detect to gigE So. I don't mind buying a new access point—I wouldn't mind having a dual-link network—but as a guy who's been networking since gated v4 was a drastic rewrite, and who often used physical sniffers in the days before Wireshark, I'm baffled. I hate being baffled. What could I possibly have changed that would result in this? How can I measure it? All I can think of is a static zap—thick carpet, socks, HVAC—but I didn't feel one, and does that really happen anymore? Can I test if it's Ethernet vs. TCP layer slowness? I'm not familiar with modern network utilities; it's hard to Google without hitting "Q: Why is my network slow? A: Is your microwave on?" If I don't get an answer here, will someone big and powerful help me migrate it to serverfault without getting screamed back here? In the words of Inigo Montoya, "I must know." Don't get all Dread Pirate Roberts on me.

  • How to open a server port outside of an OpenVPN tunnel with a pf firewall on OSX (BSD)

    - by Timbo
    I have a Mac mini that I use as a media server running XBMC and serves media from my NAS to my stereo and TV (which has been color calibrated with a Spyder3Express, happy). The Mac runs OSX 10.8.2 and the internet connection is tunneled for general privacy over OpenVPN through Tunnelblick. I believe my anonymous VPN provider pushes "redirect_gateway" to OpenVPN/Tunnelblick because when on it effectively tunnels all non-LAN traffic in- and outbound. As an unwanted side effect that also opens the boxes server ports unprotected to the outside world and bypasses my firewall-router (Netgear SRX5308). I have run nmap from outside the LAN on the VPN IP and the server ports on the mini are clearly visible and connectable. The mini has the following ports open: ssh/22, ARD/5900 and 8080+9090 for the XBMC iOS client Constellation. I also have Synology NAS which apart from LAN file serving over AFP and WebDAV only serves up an OpenVPN/1194 and a PPTP/1732 server. When outside of the LAN I connect to this from my laptop over OpenVPN and over PPTP from my iPhone. I only want to connect through AFP/548 from the mini to the NAS. The border firewall (SRX5308) just works excellently, stable and with a very high throughput when streaming from various VOD services. My connection is a 100/10 with a close to theoretical max throughput. The ruleset is as follows Inbound: PPTP/1723 Allow always to 10.0.0.40 (NAS/VPN server) from a restricted IP range >corresponding to possible cell provider range OpenVPN/1194 Allow always to 10.0.0.40 (NAS/VPN server) from any Outbound: Default outbound policy: Allow Always OpenVPN/1194 TCP Allow always from 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) OpenVPN/1194 UDP Allow always to 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) Block always from NAS to any On the Mini I have disabled the OSX Application Level Firewall because it throws popups which don't remember my choices from one time to another and that's annoying on a media server. Instead I run Little Snitch which controls outgoing connections nicely on an application level. I have configured the excellent OSX builtin firewall pf (from BSD) as follows pf.conf (Apple App firewall tie-ins removed) (# replaced with % to avoid formatting errors) ### macro name for external interface. eth_if = "en0" vpn_if = "tap0" ### wifi_if = "en1" ### %usb_if = "en3" ext_if = $eth_if LAN="{10.0.0.0/24}" ### General housekeeping rules ### ### Drop all blocked packets silently set block-policy drop ### all incoming traffic on external interface is normalized and fragmented ### packets are reassembled. scrub in on $ext_if all fragment reassemble scrub in on $vpn_if all fragment reassemble scrub out all ### exercise antispoofing on the external interface, but add the local ### loopback interface as an exception, to prevent services utilizing the ### local loop from being blocked accidentally. ### set skip on lo0 antispoof for $ext_if inet antispoof for $vpn_if inet ### spoofing protection for all interfaces block in quick from urpf-failed ############################# block all ### Access to the mini server over ssh/22 and remote desktop/5900 from LAN/en0 only pass in on $eth_if proto tcp from $LAN to any port {22, 5900, 8080, 9090} ### Allow all udp and icmp also, necessary for Constellation. Could be tightened. pass on $eth_if proto {udp, icmp} from $LAN to any ### Allow AFP to 10.0.0.40 (NAS) pass out on $eth_if proto tcp from any to 10.0.0.40 port 548 ### Allow OpenVPN tunnel setup over unprotected link (en0) only to VPN provider IPs ### and port ranges pass on $eth_if proto tcp from any to a.b.8.0/24 port 1194:1201 ### OpenVPN Tunnel rules. All traffic allowed out, only in to ports 4100-4110 ### Outgoing pings ok pass in on $vpn_if proto {tcp, udp} from any to any port 4100:4110 pass out on $vpn_if proto {tcp, udp, icmp} from any to any So what are my goals and what does the above setup achieve? (until you tell me otherwise :) 1) Full LAN access to the above ports on the mini/media server (including through my own VPN server) 2) All internet traffic from the mini/media server is anonymized and tunneled over VPN 3) If OpenVPN/Tunnelblick on the mini drops the connection, nothing is leaked both because of pf and the router outgoing ruleset. It can't even do a DNS lookup through the router. So what do I have to hide with all this? Nothing much really, I just got carried away trying to stop port scans through the VPN tunnel :) In any case this setup works perfectly and it is very stable. The Problem at last! I want to run a minecraft server and I installed that on a separate user account on the mini server (user=mc) to keep things partitioned. I don't want this server accessible through the anonymized VPN tunnel because there are lots more port scans and hacking attempts through that than over my regular IP and I don't trust java in general. So I added the following pf rule on the mini: ### Allow Minecraft public through user mc pass in on $eth_if proto {tcp,udp} from any to any port 24983 user mc pass out on $eth_if proto {tcp, udp} from any to any user mc And these additions on the border firewall: Inbound: Allow always TCP/UDP from any to 10.0.0.40 (NAS) Outbound: Allow always TCP port 80 from 10.0.0.40 to any (needed for online account checkups) This works fine but only when the OpenVPN/Tunnelblick tunnel is down. When up no connection is possbile to the minecraft server from outside of LAN. inside LAN is always OK. Everything else functions as intended. I believe the redirect_gateway push is close to the root of the problem, but I want to keep that specific VPN provider because of the fantastic throughput, price and service. The Solution? How can I open up the minecraft server port outside of the tunnel so it's only available over en0 not the VPN tunnel? Should I a static route? But I don't know which IPs will be connecting...stumbles How secure would to estimate this setup to be and do you have other improvements to share? I've searched extensively in the last few days to no avail...If you've read this far I bet you know the answer :)

  • Apache2 VirtualHost Configuration with SSL

    - by Peter
    Hello! I'm new here and I have a strange problem which needs to be solved. Previously I searched in the whole forum and I've read all of related questions but I didn't find solution to my question. We have two servers and a firewall computer. On the Server#1 there is an Apache 2.2 web server and it forwards the incoming traffic to the appropriate ports, to our subdomains by its virtual host configuration (Apache, Tomcat, IIS, Server#2 and so on). We recently bought an SSL certificate to protect one of our subdomain. I successfully installed and configured the certificate into the Apache and it works flawlessly within our local network. Our Kerio Winroute Firewall is configured to permit https traffic and it is translated to Server#1. But all of our subdomains are unavailable from outside (http & https too). Web browser shows "Failed to connect" message. Now, I enclose some parts from our httpd.conf and httpd-vhosts.conf file. httpd.conf ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2" Listen 80 ServerName dev.mydomain.hu:80 DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule ssl_module modules/mod_ssl.so Include conf/extra/httpd-vhosts.conf <IfModule ssl_module> SSLMutex default SSLRandomSeed startup builtin SSLRandomSeed connect builtin SSLSessionCache none </IfModule> httpd-vhosts.conf NameVirtualHost *:80 NameVirtualHost *:443 Listen 443 <VirtualHost *:80> DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" ServerName localhost </VirtualHost> #-------EXCHANGE SERVER-------- <VirtualHost *:80> ServerName intra.mydomain.hu ProxyRequests Off ProxyVia On ProxyPass / http://myserver:8080/ ProxyPassReverse / http://myserver:8080/ <Proxy *:80> Order deny,allow Allow from all </Proxy> <Location /> Order allow,deny Allow from all </Location> ErrorLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/exchange.log" CustomLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/exchange_cust.log" common LogLevel info </VirtualHost> #--------FITNESSE SERVER------- <VirtualHost *:80> ServerName test.mydomain.hu ProxyRequests Off <Proxy *:80> Order deny,allow Allow from all </Proxy> ProxyPass / http://myserver:8004/ ProxyPassReverse / http://myserver:8004/ <Location /> AuthType Basic AuthName "FitNesse" AuthUserFile "C:/Program Files/Apache Software Foundation/Apache2.2/auth/password" AuthGroupFile "C:/Program Files/Apache Software Foundation/Apache2.2/auth/pwgroup" require group Users Order allow,deny Allow from all </Location> ErrorLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/fitnesse.log" CustomLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/fitnesse_cust.log" common LogLevel info </VirtualHost> #----WIKI SERVER-----(SSL)- <VirtualHost *:80 *:443> ServerName wiki.mydomain.hu ServerAlias wiki.mydomain.hu SSLEngine On SSLCertificateFile "C:/Program Files/Apache Software Foundation/Apache2.2/cert/certificate.cer" SSLCertificateKeyFile "C:/Program Files/Apache Software Foundation/Apache2.2/cert/wiki.itkodex.hu.key" ProxyRequests Off <Proxy *:80> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8000/ ProxyPassReverse / http://localhost:8000/ ErrorLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/wiki.log" CustomLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/wikicust.log" common LogLevel info </VirtualHost> Because this wiki is a JSPWIKI web application, runs on Apache Tomcat therefore there is no "DocumentRoot" parameter in the VirtualHost.

  • Filtering in a HierarchicalDataTemplate via MarkupExtension?

    - by Dan Bryant
    I'm trying to create a MarkupExtension to allow filtering of items in an ItemsSource of a HierarchicalDataTemplate. In particular, I'd like to be able to supply a method name that will be executed on the DataContext in order to perform the filtering. The usage syntax I'm after looks like this: <HierarchicalDataTemplate DataType="{x:Type src:DeviceBindingViewModel}" ItemsSource="{Utilities:FilterCollection {Binding Definition.Entries}, MethodName=FilterEntries}"> <StackPanel Orientation="Horizontal"> <Image Source="{StaticResource BindingImage}" Width="24" Height="24" Margin="3"/> <TextBlock Text="{Binding DisplayName}" FontSize="12" VerticalAlignment="Center"/> </StackPanel> </HierarchicalDataTemplate> My code for the custom MarkupExtension looks like this: public sealed class FilterCollectionExtension : MarkupExtension { private readonly MultiBinding _binding; private Predicate<Object> _filterMethod; public string MethodName { get; set; } public FilterCollectionExtension(Binding binding) { _binding = new MultiBinding(); _binding.Bindings.Add(binding); //We package a reference to the DataContext with the binding so that the Converter has access to it var selfBinding = new Binding {RelativeSource = RelativeSource.Self}; _binding.Bindings.Add(selfBinding); _binding.Converter = new InternalConverter(this); } public FilterCollectionExtension(Binding binding, string methodName) : this(binding) { MethodName = methodName; } public override object ProvideValue(IServiceProvider serviceProvider) { return _binding; } private bool FilterInternal(Object dataContext, Object value) { //Filtering is only applicable if a DataContext is defined if (dataContext != null) { if (_filterMethod == null) { var type = dataContext.GetType(); var method = type.GetMethod(MethodName, new[] { typeof(Object) }); if (method == null || method.ReturnType != typeof(bool)) throw new InvalidOperationException("Could not locate a filter predicate named " + MethodName + " on the DataContext"); _filterMethod = (Predicate<Object>)Delegate.CreateDelegate(typeof(Predicate<Object>), dataContext, method); } else { if (_filterMethod.Target != dataContext) { _filterMethod = (Predicate<Object>) Delegate.CreateDelegate(typeof (Predicate<Object>), dataContext, _filterMethod.Method); } } if (_filterMethod != null) return _filterMethod(value); } //If no filtering resolved, just allow all elements return true; } private class InternalConverter : IMultiValueConverter { private readonly FilterCollectionExtension _owner; public InternalConverter(FilterCollectionExtension owner) { _owner = owner; } public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { var enumerable = values[0]; var targetElement = (FrameworkElement)values[1]; var view = CollectionViewSource.GetDefaultView(enumerable); view.Filter = item => _owner.FilterInternal(targetElement.DataContext, item); return view; } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture) { throw new NotSupportedException("Cannot convert back"); } } } I can see that the extension is instantiated and I can see it return the MultiBinding that is used by the Template. I also see the call to the InternalConverter.Convert method, which sees the expected parameters (I see the collection provided by the nested {Binding}) and is successfully able to retrieve the ICollectionView for the incoming collection. The only problem is that FilterInternal never gets called. The template is ultimately being used by a TreeView, if that's relevant. I haven't been able to figure out why the FilterInternal method is not being called and I was hoping somebody might be able to offer some insight.

  • Delphi 7 SOAP Authentication and SessionID HowTo

    - by Justin Philbrow
    Hello All, I am developing a 3 tier database application. 1.) MS SQL DB 2.) Middle tier SOAP Server (with Delphi 7) connected to the DB 3.) Clients (first win32 gui (with Delphi 7) - later other platfomrs) connected to the SOAP server I chose a SOAP Server to be open to various clients at a later stage (also some of the win32 gui clients will be stationed abroad - so the clients need to be thin) (this as suggested by Dr. Bob). I am new to SOAP and have been looking at different examples and papers about authentication. But cant quite get my head around it. I have made a SOAP server and client with Delphi's SOAP Server Application Wizard and added a SOAP SERVER Data Module, added a database connection and some datasets and providers. Connected the client with dbgrid etc and that part works fine. But I want the client first to login and then be able to access data and I want the server to log each connection and also when the client logs off or is disconnected, so I am guessing I need the sessionID and a timeout. I also want the server to be able to tell the clients who else is "connected" (or whos session is still active) at any given time. I have gathered that I need to make a authentication header, but cant figure out where or who I can get a sessionID. I presume that each time a client connectes to the server the server generates a sessionID? How do I get this? Any help or suggestions/pointer would be appreciated, thanks Justin OK take 2: OK, I have done the following so far (this is used from the example Bank Account SOAP application that comes with Delphi 7): procedure TForm1.btnLoginClick(Sender: TObject); var H: TAuthHeader; Headers: ISOAPHeaders; SoapData: IThorPayServerDB; begin SoapData := HTTPRIOOnForm as IThorPayServerDB; if not(SoapData.login(edtUser.Text,edtPassword.Text)) then begin showmessage('Not correct login'); exit; end; Headers := SoapData as ISoapHeaders; { Get the header from the incoming message } Headers.Get(TAuthHeader, TSoapHeader(H)); try if H < nil then begin FIdKey := H.IdNumber; FTimeStamp := H.TimeStamp; end else ShowMessage('No authentication header received from server'); finally H.Free; end; if FIdKey 0 then showmessage('Authenticated');; end; The SoapData.login returns the correct result, but for some reason I cant get hold of the header. In this case H is nil and the result becomes 'No authentication header received from server'. If I intersept the SOAP xml I can see that the header is there, here is the returned package: 1 1 4208687 2010-05-14T10:03:49.469+03:00 true Anyone any idea? In this case I am not using the SOAPConnetion that I am using for the DB, but a seperate HTTPTRIO component.

  • Is Multicast broken for Android 2.0.1 (currently on the DROID) or am I missing something?

    - by Gubatron
    This code works perfectly in Ubuntu, in Windows and MacOSX, it also works fine with a Nexus-One currently running firmware 2.1.1. I start sending and listening multicast datagrams, and all the computers and the Nexus-One will see each other perfectly. Then I run the same code on a Droid (Firmware 2.0.1), and everybody will get the packets sent by the Droid, but the droid will listen only to it's own packets. This is the run() method of a thread that's constantly listening on a Multicast group for incoming packets sent to that group. I'm running my tests on a local network where I have multicast support enabled in the router. My goal is to have devices meet each other as they come on line by broadcasting packages to a multicast group. public void run() { byte[] buffer = new byte[65535]; DatagramPacket dp = new DatagramPacket(buffer, buffer.length); try{ MulticastSocket ms = new MulticastSocket(_port); ms.setNetworkInterface(_ni); //non loopback network interface passed ms.joinGroup(_ia); //the multicast address, currently 224.0.1.16 Log.v(TAG,"Joined Group " + _ia); while (true) { ms.receive(dp); String s = new String(dp.getData(),0,dp.getLength()); Log.v(TAG,"Received Package on "+ _ni.getName() +": " + s); Message m = new Message(); Bundle b = new Bundle(); b.putString("event", "Listener ("+_ni.getName()+"): \"" + s + "\""); m.setData(b); dispatchMessage(m); //send to ui thread } } catch (SocketException se) { System.err.println(se); } catch (IOException ie) { System.err.println(ie); } } Over here, is the code that sends the Multicast Datagram out of every valid network interface available (that's not the loopback interface). public void sendPing() { MulticastSocket ms = null; try { ms = new MulticastSocket(_port); ms.setTimeToLive(TTL_GLOBAL); List<NetworkInterface> interfaces = getMulticastNonLoopbackNetworkInterfaces(); for (NetworkInterface iface : interfaces) { //skip loopback if (iface.getName().equals("lo")) continue; ms.setNetworkInterface(iface); _buffer = ("FW-"+ _name +" PING ("+iface.getName()+":"+iface.getInetAddresses().nextElement()+")").getBytes(); DatagramPacket dp = new DatagramPacket(_buffer, _buffer.length,_ia,_port); ms.send(dp); Log.v(TAG,"Announcer: Sent packet - " + new String(_buffer) + " from " + iface.getDisplayName()); } } catch (IOException e) { e.printStackTrace(); } catch (Exception e2) { e2.printStackTrace(); } } Update (April 2nd 2010) I found a way to have the Droid's network interface to communicate using Multicast! _wifiMulticastLock = ((WifiManager) context.getSystemService(Context.WIFI_SERVICE)).createMulticastLock("multicastLockNameHere"); _wifiMulticastLock.acquire(); Then when you're done... if (_wifiMulticastLock != null && _wifiMulticastLock.isHeld()) _wifiMulticastLock.release(); After I did this, the Droid started sending and receiving UDP Datagrams on a Multicast group. gubatron

  • Reading off a socket until end of line C#?

    - by Omar Kooheji
    I'm trying to write a service that listens to a TCP Socket on a given port until an end of line is recived and then based on the "line" that was received executes a command. I've followed a basic socket programming tutorial for c# and have come up with the following code to listen to a socket: public void StartListening() { _log.Debug("Creating Maing TCP Listen Socket"); _mainSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any, _port); _log.Debug("Binding to local IP Address"); _mainSocket.Bind(ipLocal); _log.DebugFormat("Listening to port {0}",_port); _mainSocket.Listen(10); _log.Debug("Creating Asynchronous callback for client connections"); _mainSocket.BeginAccept(new AsyncCallback(OnClientConnect), null); } public void OnClientConnect(IAsyncResult asyn) { try { _log.Debug("OnClientConnect Creating worker socket"); Socket workerSocket = _mainSocket.EndAccept(asyn); _log.Debug("Adding worker socket to list"); _workerSockets.Add(workerSocket); _log.Debug("Waiting For Data"); WaitForData(workerSocket); _log.DebugFormat("Clients Connected [{0}]", _workerSockets.Count); _mainSocket.BeginAccept(new AsyncCallback(OnClientConnect), null); } catch (ObjectDisposedException) { _log.Error("OnClientConnection: Socket has been closed\n"); } catch (SocketException se) { _log.Error("Socket Exception", se); } } public class SocketPacket { private System.Net.Sockets.Socket _currentSocket; public System.Net.Sockets.Socket CurrentSocket { get { return _currentSocket; } set { _currentSocket = value; } } private byte[] _dataBuffer = new byte[1]; public byte[] DataBuffer { get { return _dataBuffer; } set { _dataBuffer = value; } } } private void WaitForData(Socket workerSocket) { _log.Debug("Entering WaitForData"); try { lock (this) { if (_workerCallback == null) { _log.Debug("Initializing worker callback to OnDataRecieved"); _workerCallback = new AsyncCallback(OnDataRecieved); } } SocketPacket socketPacket = new SocketPacket(); socketPacket.CurrentSocket = workerSocket; workerSocket.BeginReceive(socketPacket.DataBuffer, 0, socketPacket.DataBuffer.Length, SocketFlags.None, _workerCallback, socketPacket); } catch (SocketException se) { _log.Error("Socket Exception", se); } } public void OnDataRecieved(IAsyncResult asyn) { SocketPacket socketData = (SocketPacket)asyn.AsyncState; try { int iRx = socketData.CurrentSocket.EndReceive(asyn); char[] chars = new char[iRx + 1]; _log.DebugFormat("Created Char array to hold incomming data. [{0}]",iRx+1); System.Text.Decoder decoder = System.Text.Encoding.UTF8.GetDecoder(); int charLength = decoder.GetChars(socketData.DataBuffer, 0, iRx, chars, 0); _log.DebugFormat("Read [{0}] characters",charLength); String data = new String(chars); _log.DebugFormat("Read in String \"{0}\"",data); WaitForData(socketData.CurrentSocket); } catch (ObjectDisposedException) { _log.Error("OnDataReceived: Socket has been closed. Removing Socket"); _workerSockets.Remove(socketData.CurrentSocket); } catch (SocketException se) { _log.Error("SocketException:",se); _workerSockets.Remove(socketData.CurrentSocket); } } This I thought was going to be a good basis for what I wanted to do, but the code I have appended the incoming characters to a text box one by one and didn't do anything with it. Which doesn't really work for what I want to do. My main issue is the decoupling of the OnDataReceived method from the Wait for data method. which means I'm having issues building a string (I would use a string builder but I can accept multiple connections so that doesn't really work. Ideally I'd like to look while listening to a socket until I see and end of line character and then call a method with the resulting string as a parameter. What's the best way to go about doing this.

  • Receicing POST data in ASP.NET

    - by grast
    Hi, I want to use ASP for code generation in a C# desktop application. To achieve this, I set up a simple host (derived from System.MarshalByRefObject) that processes a System.Web.Hosting.SimpleWorkerRequest via HttpRuntime.ProcessRequest. This processes the ASPX script specified by the incoming request (using System.Net.HttpListener to wait for requests). The client-part is represented by a System.ComponentModel.BackgroundWorker that builds the System.Net.HttpWebRequest and receives the response from the server. A simplified version of my client-part-code looks like this: private void SendRequest(object sender, DoWorkEventArgs e) { // create request with GET parameter var uri = "http://localhost:9876/test.aspx?getTest=321"; var request = (HttpWebRequest)WebRequest.Create(uri); // append POST parameter request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; var postData = Encoding.Default.GetBytes("postTest=654"); var postDataStream = request.GetRequestStream(); postDataStream.Write(postData, 0, postData.Length); // send request, wait for response and store/print content using (var response = (HttpWebResponse)request.GetResponse()) { using (var reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { _processsedContent = reader.ReadToEnd(); Debug.Print(_processsedContent); } } } My server-part-code looks like this (without exception-handling etc.): public void ProcessRequests() { // HttpListener at http://localhost:9876/ var listener = SetupListener(); // SimpleHost created by ApplicationHost.CreateApplicationHost var host = SetupHost(); while (_running) { var context = listener.GetContext(); using (var writer = new StreamWriter(context.Response.OutputStream)) { // process ASP script and send response back to client host.ProcessRequest(GetPage(context), GetQuery(context), writer); } context.Response.Close(); } } So far all this works fine as long as I just use GET parameters. But when it comes to receiving POST data in my ASPX script I run into trouble. For testing I use the following script: // GET parameters are working: var getTest = Request.QueryString["getTest"]; Response.Write("getTest: " + getTest); // prints "getTest: 321" // don't know how to access POST parameters: var postTest1 = Request.Form["postTest"]; // Request.Form is empty?! Response.Write("postTest1: " + postTest1); // so this prints "postTest1: " var postTest2 = Request.Params["postTest"]; // Request.Params is empty?! Response.Write("postTest2: " + postTest2); // so this prints "postTest2: " It seems that the System.Web.HttpRequest object I'm dealing with in ASP does not contain any information about my POST parameter "postTest". I inspected it in debug mode and none of the members did contain neither the parameter-name "postTest" nor the parameter-value "654". I also tried the BinaryRead method of Request, but unfortunately it is empty. This corresponds to Request.InputStream==null and Request.ContentLength==0. And to make things really confusing the Request.HttpMethod member is set to "GET"?! To isolate the problem I tested the code by using a PHP script instead of the ASPX script. This is very simple: print_r($_GET); // prints all GET variables print_r($_POST); // prints all POST variables And the result is: Array ( [getTest] = 321 ) Array ( [postTest] = 654 ) So with the PHP script it works, I can access the POST data. Why does the ASPX script don't? What am I doing wrong? Is there a special accessor or method in the Response object? Can anyone give a hint or even know how to solve this? Thanks in advance.
