• Sendmail Alias for Nonlocal Email Account

  - by Mark Roddy

  I admin a server which is running a number of web applications for a software dev team (source control, bug tracking, etc). The server has sendmail running solely as a transport to the departmental email server over which I have no control. We have someone who is still in the department but no longer on the dev team so I need to configure the transport agent to redirect all outgoing email (which would be coming from these applications) to the person that has taken their place. I added an entry in /etc/aliases like such: [email protected]: [email protected] But when I run /etc/init.d/sendmail newaliases I get the following error: /etc/mail/aliases: line 32: [email protected]... cannot alias non-local names So clearly I'm doing something I shouldn't. Is there a way to get aliases to work with non-local names or alternatively is their a way to accomplish my goal of redirecting outgoing mail for this user to another one? Technical Specs if the matter: Ubuntu 6.06 sendmail 8.13 (ubuntu provided package)

• JBoss naming service port conflict

  - by Kramer

  I am having trouble getting JBoss started. I am running JBoss 5.1.0 on Mac OSX (yes, I know it is an old version, but that’s what the application is certified on for now). I am using Apple’s JVM 1.6.0_37. I get the following error when trying to use JBoss (there are some more exceptions, but these are the first few): Error installing to Start: name=jboss:service=Naming state=Create mode=Manual requiredState=Installed java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) at sun.rmi.transport.tcp.TCPTransport.exportObject(TCPTransport.java:218) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:383) 16:57:15,596 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/Users/home/server/jboss-5.1.0.GA/server/myserver/conf/jboss-service.xml state=PreReal mode=Manual requiredState=Real org.jboss.deployers.spi.DeploymentException: Error deploying: jboss:service=Naming at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:118) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:46) Caused by: java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) Now I know what you are thinking, that I am running something that conflicts with that port, but I have used lsof and there is nothing listed on that port. I have tried changing the port in conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml: <bean class="org.jboss.services.binding.ServiceBindingMetadata"> <property name="serviceName">jboss:service=Naming</property> <property name="bindingName">RmiPort</property> <property name="port">5098</property> <property name="description">Socket Naming service uses to receive RMI requests from client proxies</property> </bean> Unfortunately, I then get the name errors with the new port number. I also installed a network monitoring tool on my box and it doesn't look like any ports are being opened when I start jboss, but it is possible, that the tool might be missing a port that is opened and then closed quickly. Any ideas what could be the problem or how to fix it?

• design question for transportation agency/workflow system

  - by George2

  I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. Thanks in advance!

• How can I use target mode in Linux with USB?

  - by dash17291

  Kernel 3.5 introduces: This release includes a driver for using an IEEE-1394 connection as a SCSI transport. This enables to expose SCSI devices to other nodes on the Firewire bus, for example hard disk drives. It's a similar functionality to Firewire Target Disk Mode on many Apple computers. This release also adds a usb-gadget driver that does the same with USB. The driver supports two USB protocols are supported that is BBB or BOT (Bulk Only Transport) and UAS (USB Attached SCSI). BOT is advertised on alternative interface 0 (primary) and UAS is on alternative interface 1. Both protocols can work on USB 2.0 and USB 3.0. UAS utilizes the USB 3.0 feature called streams support. http://kernelnewbies.org/Linux_3.5 I have an Arch Linux with kernel 3.5.3-1 and wanna try out this feature.

• Cross Domain access of self hosted WCF services?

  - by Macnique

  I have developed a WPF application which communicates with a set of self hosted WCF services which are under same domain and I use the following setup in the config files. <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> <message clientCredentialType="Windows" /> </security> I hosted the services on a server in different domain .I can achieve the communication by setting the security mode to "None" which is not ideal. Is there any other setting i can user for cross domain communication or i have to do with some trusted certificates ? I would be glad if some one can guide me because all the searches on google directed me to silverlight applications +Crossdomain.xml+WCF but i have't seen any combination of WPF on crossdomain environment.

• JSF SSL Hazzard

  - by java beginner

  In my application it is required that only certain pages need to be secured using SSL so I configured it security-constraint> <display-name>Security Settings</display-name> <web-resource-collection> <web-resource-name>SSL Pages</web-resource-name> <description/> <url-pattern>/*.jsp</url-pattern> <http-method>GET</http-method> <http-method>POST</http-method> </web-resource-collection> <user-data-constraint> <description>CONFIDENTIAL requires SSL</description> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> and added filter http://blogs.sun.com/jluehe/entry/how_to_downshift_from_https but only one hazard is there. I am using it with richFaces. Once it goes to HTTPS its not changing the page—I mean if I perform post action it doesn't actually happen. But if I do it from the local machine's browser it works perfectly, from a remote browser it stucks with HTTPS and not changing after that. Here is my web.xml's snap: <filter> <filter-name>MyFilter</filter-name> <filter-class>MyFilter</filter-class> <init-param> <param-name>httpPort</param-name> <param-value>8080</param-value> </init-param> </filter> <filter-mapping> <filter-name>MyFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <security-constraint> <web-resource-collection> <web-resource-name>Protected resource</web-resource-name> <url-pattern>somePattern</url-pattern> <http-method>GET</http-method> <http-method>POST</http-method> </web-resource-collection> <user-data-constraint> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint> and some other filters of richfaces. Problem is strange. If I try to access the web app from local's machine's browser it works fine but in remote machine's browser once it get into HTTP, all the forms of that page aswell as href stops working.(JSF,facelet is used.)

• WCF service using duplex channel in different domains

  - by ds1

  I have a WCF service and a Windows client. They communicate via a Duplex WCF channel which when I run from within a single network domain runs fine, but when I put the server on a separate network domain I get the following message in the WCF server trace... The message with to 'net.tcp://abc:8731/ActiveAreaService/mex/mex' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree. So, it looks like the communication just work in one direction (from client to server) if the components are in two separate domains. The Network domains are fully trusted, so I'm a little confused as to what else could cause this? Server app.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="JobController.ActiveAreaBehavior"> <serviceMetadata httpGetEnabled="false" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="JobController.ActiveAreaBehavior" name="JobController.ActiveAreaServer"> <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://SERVER:8731/ActiveAreaService/" /> </baseAddresses> </host> </service> </services> </system.serviceModel> </configuration> but I also add an end point programmatically in Visual C++ host = gcnew ServiceHost(ActiveAreaServer::typeid); NetTcpBinding^ binding = gcnew NetTcpBinding(); binding->MaxBufferSize = Int32::MaxValue; binding->MaxReceivedMessageSize = Int32::MaxValue; binding->ReceiveTimeout = TimeSpan::MaxValue; binding->Security->Mode = SecurityMode::Transport; binding->Security->Transport->ClientCredentialType = TcpClientCredentialType::Windows; ServiceEndpoint^ ep = host->AddServiceEndpoint(IActiveAreaServer::typeid, binding, String::Empty); // Use the base address Client app.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_IActiveAreaServer" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" maxReceivedMessageSize="65536"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://SERVER:8731/ActiveAreaService/" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IActiveAreaServer" contract="ActiveArea.IActiveAreaServer" name="NetTcpBinding_IActiveAreaServer"> <identity> <userPrincipalName value="[email protected]" /> </identity> </endpoint> </client> </system.serviceModel> </configuration> Any help is appreciated!

• How to expose MEX when I need the service to have NTLM authentication

  - by Ram Amos

  I'm developing a WCF service that is RESTful and SOAP, now both of them needs to be with NTLM authentication. I also want to expose a MEX endpoint so that others can easily reference the service and work with it. Now when I set IIS to require windows authentication I can use the REST service and make calls to the service succesfully, but when I want to reference the service with SVCUTIL it throws an error that it requires to be anonymous. Here's my web.config: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/> <bindings> <basicHttpBinding> <binding name="basicHttpBinding" maxReceivedMessageSize="214748563" maxBufferSize="214748563" maxBufferPoolSize="214748563"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm"> </transport> </security> </binding> </basicHttpBinding> <webHttpBinding> <binding name="webHttpBinding" maxReceivedMessageSize="214748563" maxBufferSize="214748563" maxBufferPoolSize="214748563"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm"> </transport> </security> </binding> </webHttpBinding> <mexHttpBinding> <binding name="mexHttpBinding"></binding> </mexHttpBinding> </bindings> <standardEndpoints> <webHttpEndpoint> <standardEndpoint name="" automaticFormatSelectionEnabled="true" helpEnabled="True"> </standardEndpoint> </webHttpEndpoint> </standardEndpoints> <services> <service name="Intel.ResourceScheduler.Service" behaviorConfiguration="Meta"> <clear /> <endpoint address="soap" name="SOAP" binding="basicHttpBinding" contract="Intel.ResourceScheduler.Service.IResourceSchedulerService" listenUriMode="Explicit" /> <endpoint address="" name="rest" binding="webHttpBinding" behaviorConfiguration="REST" contract="Intel.ResourceScheduler.Service.IResourceSchedulerService" /> <endpoint address="mex" name="mex" binding="mexHttpBinding" behaviorConfiguration="" contract="IMetadataExchange" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="REST"> <webHttp /> </behavior> <behavior name="WCFBehavior"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="Meta"> <serviceMetadata httpGetEnabled="true"/> </behavior> <behavior name="REST"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> <behavior name="WCFBehavior"> <serviceMetadata httpGetEnabled="true"/> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> </behavior> <behavior name=""> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="true" /> <!-- To receive exception details in faults for debugging purposes, set the value below to true.

• Building services with .Net Part 1

  - by Allan Rwakatungu

  On the 26th of May 2010 , I made a presentation to the .NET user group meeting (thanks to Malisa Ncube for organizing this event every month … ). If you missed my presentation , we talked about why we should all be building services … better still using the .NET framework. This blog post is an introduction to services , why you would want to build services and how you can build services using the .NET framework. What is a service? OASIS defines service as "a mechanism to enable access to one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies as specified by the service description." [1]. If the above definition sounds to academic , you can also define a service as loosely coupled units of functionality that have no calls to each other embedded in the. Instead of services embedding calls to each other in their service code they use defined protocols that describe how services pass and parse messages. This is a good way to think about services if you’re from an objected oriented background. While in object oriented programming functions make calls to each other, in service oriented programming, functions pass messages between each other. Why would you want to use services? 1. If your enterprise architecture looks like this   Services are the building blocks for SOA . With SOA you can move away from the sphaggetti infrastructure that is common in most enterprises. The complexity or lack of visibility of the integration points in your enterprises makes it difficult and costly to implement new initiatives and changes into the business - and even impossible in some cases - as it is not possible to identify the impact a change in one system might have to other systems. With services you can move to an architecture like this Your building blocks from Spaghetti infrastructure to something that is more well-defined and manageable to achieve cost efficiency and not least business agility - enabling you to react to changes in the market with speed and achieve operational efficiency and control are services. 2. If you want to become the Gates or Zuckerburger. Have you heard about Web 2.0 ? Mashups? Software as a service (SAAS) ? Cloud computing ?   They all offer you the opportunity to have scalable but low cost business models and they built using services.  Some of my favorite companies that leverage services for their business models include  https://www.salesforce.com/ (cloud CRM) http://www. twitter.com (more people use twitter clients built by 3rd parties than their official clients) http://www.kayak.com/ (compares data from other travel sites to give information to users in one location) Services with the .NET framework      If you are a .NET developer and you want to develop services, Windows Communication Framework (WCF) is the tool for you. WCF is Microsoft’s unified programming model (service model) for building service oriented applications. ( Before .NET 3.0 you had several models for programming services in .NET including .NET remoting, Web services (ASMX), COM +, Microsoft Messaging queuing (MSMQ) etc, after .NET 3.0 the programming model was unified into one i.e. WCF ). Windows Communication Framework (WCF) provides you 1. An Software Development Kit (SDK) for creating SOA applications 2. A runtime for running services on the Windows platform Why should you use Windows Communication Foundation if you’re programming services?   1. It supports interoperable and open standards e.g. WS* protocols for programming SOAP services 2. It has a unified programming model. Whether you use TCP or Http or Pipes or transmitting using Messaging Queues, programmers need to learn just one way to program. Previously you had .NET remoting, MSMQ, Web services, COM+ and they were all done differently 3. Productive programming model You don’t have to worry about all the plumbing involved to write services. You have a rich declarative programming model to add stuff like logging, transactions, and reliable messages in-built in the Windows Communication Framework. Understanding services in WCF The basic principles of WCF are as easy as ABC A – Address This is where the service is located B- Binding This describes how you communicate with the service e.g. Use TCP, HTTP or both. How to exchange security information with the service etc. C – Contract This defines what the service can do. E.g. Pay water bill, Make a phone call A - Addresses In WCF, an address is a combination of transport, server name, port and path Example addresses may include http://localhost:8001 net.tcp://localhost:8002/MyService net.pipe://localhost/MyPipe net.msmq://localhost/private/MyService net.msmq://localhost/MyService B- Binding   There are numerous ways to communicate with services , different ways that a message can be formatted/sent/secured, that allows you to tailor your service for the compatibility/performance you require for your solution. Transport You can use HTTP TCP MSMQ , Named pipes, Your own custom transport etc Message You  can send a plain text binary, Message Transmission Optimization Mechanism (MTOM) message Communication security No security Transport security Message security Authenticating and authorizing callers etc Behaviour You service can support Transactions Be reliable Use queues Support ajax etc C - Contract You define what your service can do using Service contracts :- Define operations that your service can do, communications and behaviours Data contracts :- Define the messages that are passed from and into your service and how they are formatted Fault contracts :- Defines errors types in your service   As an example, suppose your service service shows money. You define your service contract using a interface [ServiceContract] public interface IShowMeTheMoney {   [OperationContract]    Money Show(); } You define the data contract by annotating a class it with the Data Contract attribute and fields you want to pass in the message as Data Members. (Note:- In the latest versions of WCF you dont have to use attributes if you passing all the objects properties in the message) [DataContract] public Money {   [DataMember]   public string Currency { get; set; }   [DataMember]   public Decimal Amount { get; set; }   public string Comment { get; set; } } Features of Windows Communication Foundation Windows Communication Foundation is not only simple but feature rich , offering you several options to tweak your service to fit your business requirements. Some of the features of WCF include 1. Workflow services You can combine WCF with Windows WorkFlow Foundation (WWF) to write workflow type services 2. Control how your data (messages) are transferred and serialized e.g. you can serialize your business objects as XML or binary 3. control over session management , instance creation and concurrency management without writing code if you like 4. Queues and reliable sessions. You can store messages from the sending client and later forward them to the receiving application. You can also guarantee that messages will arrive at their destincation. 5.Transactions:  You can have different services participate in a transaction operations that can be rolled back if needed 6. Security. WCF has rich features for authorization and authentication  as well as keep audit trails 7. Web programming model. WCF allows developers to expose services as non SOAP endpoints 8. Inbuilt features that you can use to write JSON and services that support AJAX applications And lots more In my next blog I will show you how you can use WCF features to write a real world business service.               Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 ]] /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• Catch Me If You Can

  - by Knut Vatsendvik

  Suppose you have a Proxy based Web Service using Oracle Service Bus. In a stage in the request pipeline,  you are using a Publish action to publish the incoming message to a JMS queue using a Business Service. What if the outbound transport provider throws an exception (outside of your pipeline)? Is your pipeline able to catch the error with an error handler?? This situation could occur because of a faulty connection, suspended queue, or some other reason. Here is the Request Pipeline in our simple test case. With an Error Handler added to the message flow containing a simple Log action. By default, the Publish action will invoke the service in a fire and forget fashion. Therefore any exception that occurs in the outbound transport will go unnoticed as shown in the following Invocation Trace. So what now? In a message flow, you can apply a Routing Options action to modify any or all of the following properties in the outbound request: URI, Quality of Service, Mode, Retry parameters, Message Priority. Now add the Routing Options action to the Request Action as shown below. Click the Routing Options to display its properties in the Properties View. Select the QoS option to set the Quality of Service element. Select Exactly Once to override the default setting, and Republish the project. The invocation will now block until the message is completely processed. Trying the same test case as earlier generates the following Invocation Trace showing that the Error Handler is now triggered.

• Mobility Card in Bangalore for Transportation

  - by Rekha

  Transport Minister R Ashoka announced Bangalore Metropolitan Transport Corporation (BMTC) services are going to be best in the world soon. BMTC has planned to launch a Mobility Card with which commuters can get rides in BMTC, KSRTC and future Metro Train facilities without buying tickets for each ride. The conductor with have a simple device in which the commuters can swipe their cards to deduct the ticket tarrif for bus or metro rides automatically. This Mobility card can be obtained by paying a fixed amount. This method is time saving and the commuters can be saved from paying the exact change for tickets. Ashoka says the Volvo Vayu Vaira services have internet connectivity and voice announcements of every bus stop names and this has been appreciated by the commuters. With WiFi Connections in Shatabdi Trains soon and Mobility Cards, India is soon to match the services of US Standards. Government officials are keen in implementing these services before the end of this year. Hope all these services are well used and maintained.   This article titled,Mobility Card in Bangalore for Transportation, was originally published at Tech Dreams.

• Do we have enough time to build an electric car future?

  - by julien.groues

  A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html

• 'pip install carbon' looks like it works, but pip disagrees afterward

  - by fennec

  I'm trying to use pip to install the package carbon, a package related to statistics collection. When I run pip install carbon, it looks like everything works. However, pip is unconvinced that the package is actually installed. (This ultimately causes trouble because I'm using Puppet, and have a rule to install carbon using pip, and when puppet asks pip "is this package installed?" it says "no" and it reinstalls it again.) How do I figure out what's preventing pip from recognizing the success of this installation?

• 301 rewrite loop with a lowercase URL rule and a URL slug rule [on hold]

  - by anyvendetta

  I need to do a 301 rewrite to force all urls to become lowercase. I put in .htaccess (RewriteMap lc int:tolower in httpd.conf): RewriteCond %{REQUEST_URI} [A-Z] RewriteRule . ${lc:{REQUEST_URI}} [R=301,L] Everything works just fine except to urls with subcategories which in this case are: /category-1256-Product-page-example.html The numer 1256 refers to a “subcategory”. So when i try to access /category-1256-Product-page-example.html gives me a loop error message. I think another redirect rules are making the loop but dunno how to fix it because are just this urls rewrite rules that don't work with the above rewrite. Rewriterule ^main-site-url/category-([0-9]*)-([-_a-zA-Z0-9]*)\.html$ /subcategories.php?idcategory_main=1&idcategory=$1&category=$2 [L] Rewriterule ^main-site-url/([0-9]*)-([-_a-zA-Z0-9]*)-([0-9]*)\.html$ /file.php?idcategory_main=1&idsubcategory=$1&product=$2&idproduct=$3 [L]

• What Every Developer Should Know About MSI Components

  - by Alois Kraus

  Hopefully nothing. But if you have to do more than simple XCopy deployment and you need to support updates, upgrades and perhaps side by side scenarios there is no way around MSI. You can create Msi files with a Visual Studio Setup project which is severely limited or you can use the Windows Installer Toolset. I cannot talk about WIX with my German colleagues because WIX has a very special meaning. It is funny to always use the long name when I talk about deployment possibilities. Alternatively you can buy commercial tools which help you to author Msi files but I am not sure how good they are. Given enough pain with existing solutions you can also learn the MSI Apis and create your own packaging solution. If I were you I would use either a commercial visual tool when you do easy deployments or use the free Windows Installer Toolset. Once you know the WIX schema you can create well formed wix xml files easily with any editor. Then you can “compile” from the wxs files your Msi package. Recently I had the “pleasure” to get my hands dirty with C++ (again) and the MSI technology. Installation is a complex topic but after several month of digging into arcane MSI issues I can safely say that there should exist an easier way to install and update files as today. I am not alone with this statement as John Robbins (creator of the cool tool Paraffin) states: “.. It's a brittle and scary API in Windows …”. To help other people struggling with installation issues I present you the advice I (and others) found useful and what will happen if you ignore this advice. What is a MSI file? A MSI file is basically a database with tables which reference each other to control how your un/installation should work. The basic idea is that you declare via these tables what you want to install and MSI controls the how to get your stuff onto or off your machine. Your “stuff” consists usually of files, registry keys, shortcuts and environment variables. Therefore the most important tables are File, Registry, Environment and Shortcut table which define what will be un/installed. The key to master MSI is that every resource (file, registry key ,…) is associated with a MSI component. The actual payload consists of compressed files in the CAB format which can either be embedded into the MSI file or reside beside the MSI file or in a subdirectory below it. To examine MSI files you need Orca a free MSI editor provided by MS. There is also another free editor called Super Orca which does support diffs between MSI and it does not lock the MSI files. But since Orca comes with a shell extension I tend to use only Orca because it is so easy to right click on a MSI file and open it with this tool. How Do I Install It? Double click it. This does work for fresh installations as well as major upgrades. Updates need to be installed via the command line via msiexec /i <msi> REINSTALL=ALL REINSTALLMODE=vomus   This tells the installer to reinstall all already installed features (new features will NOT be installed). The reinstallmode letters do force an overwrite of the old cached package in the %WINDIR%\Installer folder. All files, shortcuts and registry keys are redeployed if they are missing or need to be replaced with a newer version. When things did go really wrong and you want to overwrite everything unconditionally use REINSTALLMODE=vamus. How To Enable MSI Logs? You can download a MSI from Microsoft which installs some registry keys to enable full MSI logging. The log files can be found in your %TEMP% folder and are called MSIxxxx.log. Alternatively you can add to your msiexec command line the option msiexec …. /l*vx <LogFileName> Personally I find it rather strange that * does not mean full logging. To really get all logs I need to add v and x which is documented in the msiexec help but I still find this behavior unintuitive. What are MSI components? The whole MSI logic is bound to the concept of MSI components. Nearly every msi table has a Component column which binds an installable resource to a component. Below are the screenshots of the FeatureComponents and Component table of an example MSI. The Feature table defines basically the feature hierarchy.  To find out what belongs to a feature you need to look at the FeatureComponents table where for each feature the components are listed which will be installed when a feature is installed. The MSI components are defined in the  Component table. This table has as first column the component name and as second column the component id which is a GUID. All resources you want to install belong to a MSI component. Therefore nearly all MSI tables have a Component_ column which contains the component name. If you look e.g. a the File table you see that every file belongs to a component which is true for all other tables which install resources. The component table is the glue between all other tables which contain the resources you want to install. So far so easy. Why is MSI then so complex? Most MSI problems arise from the fact that you did violate a MSI component rule in one or the other way. When you install a feature the reference count for all components belonging to this feature will increase by one. If your component is installed by more than one feature it will get a higher refcount. When you uninstall a feature its refcount will drop by one. Interesting things happen if the component reference count reaches zero: Then all associated resources will be deleted. That looks like a reasonable thing and it is. What it makes complex are the strange component rules you have to follow. Below are some important component rules from the Tao of the Windows Installer … Rule 16: Follow Component Rules Components are a very important part of the Installer technology. They are the means whereby the Installer manages the resources that make up your application. The SDK provides the following guidelines for creating components in your package: Never create two components that install a resource under the same name and target location. If a resource must be duplicated in multiple components, change its name or target location in each component. This rule should be applied across applications, products, product versions, and companies. Two components must not have the same key path file. This is a consequence of the previous rule. The key path value points to a particular file or folder belonging to the component that the installer uses to detect the component. If two components had the same key path file, the installer would be unable to distinguish which component is installed. Two components however may share a key path folder. Do not create a version of a component that is incompatible with all previous versions of the component. This rule should be applied across applications, products, product versions, and companies. Do not create components containing resources that will need to be installed into more than one directory on the user’s system. The installer installs all of the resources in a component into the same directory. It is not possible to install some resources into subdirectories. Do not include more than one COM server per component. If a component contains a COM server, this must be the key path for the component. Do not specify more than one file per component as a target for the Start menu or a Desktop shortcut. … And these rules do not even talk about component ids, update packages and upgrades which you need to understand as well. Lets suppose you install two MSIs (MSI1 and MSI2) which have the same ComponentId but different component names. Both do install the same file. What will happen when you uninstall MSI2?   Hm the file should stay there. But the component names are different. Yes and yes. But MSI uses not use the component name as key for the refcount. Instead the ComponentId column of the Component table which contains a GUID is used as identifier under which the refcount is stored. The components Comp1 and Comp2 are identical from the MSI perspective. After the installation of both MSIs the Component with the Id {100000….} has a refcount of two. After uninstallation of one MSI there is still a refcount of one which drops to zero just as expected when we uninstall the last msi. Then the file which was the same for both MSIs is deleted. You should remember that MSI keeps a refcount across MSIs for components with the same component id. MSI does manage components not the resources you did install. The resources associated with a component are then and only then deleted when the refcount of the component reaches zero.   The dependencies between features, components and resources can be described as relations. m,k are numbers >= 1, n can be 0. Inside a MSI the following relations are valid Feature    1  –> n Components Component    1 –> m Features Component      1  –>  k Resources These relations express that one feature can install several components and features can share components between them. Every (meaningful) component will install at least one resource which means that its name (primary key to stay in database speak) does occur in some other table in the Component column as value which installs some resource. Lets make it clear with an example. We want to install with the feature MainFeature some files a registry key and a shortcut. We can then create components Comp1..3 which are referenced by the resources defined in the corresponding tables.   Feature Component Registry File Shortcuts MainFeature Comp1 RegistryKey1     MainFeature Comp2   File.txt   MainFeature Comp3   File2.txt Shortcut to File2.txt   It is illegal that the same resource is part of more than one component since this would break the refcount mechanism. Lets illustrate this:            Feature ComponentId Resource Reference Count Feature1 {1000-…} File1.txt 1 Feature2 {2000-….} File1.txt 1 The installation part works well but what happens when you uninstall Feature2? Component {20000…} gets a refcount of zero where MSI deletes all resources belonging to this component. In this case File1.txt will be deleted. But Feature1 still has another component {10000…} with a refcount of one which means that the file was deleted too early. You just have ruined your installation. To fix it you then need to click on the Repair button under Add/Remove Programs to let MSI reinstall any missing registry keys, files or shortcuts. The vigilant reader might has noticed that there is more in the Component table. Beside its name and GUID it has also an installation directory, attributes and a KeyPath. The KeyPath is a reference to a file or registry key which is used to detect if the component is already installed. This becomes important when you repair or uninstall a component. To find out if the component is already installed MSI checks if the registry key or file referenced by the KeyPath property does exist. When it does not exist it assumes that it was either already uninstalled (can lead to problems during uninstall) or that it is already installed and all is fine. Why is this detail so important? Lets put all files into one component. The KeyPath should be then one of the files of your component to check if it was installed or not. When your installation becomes corrupt because a file was deleted you cannot repair it with the Repair button under Add/Remove Programs because MSI checks the component integrity via the Resource referenced by its KeyPath. As long as you did not delete the KeyPath file MSI thinks all resources with your component are installed and never executes any repair action. You get even more trouble when you try to remove files during an upgrade (you cannot remove files during an update) from your super component which contains all files. The only way out and therefore best practice is to assign for every resource you want to install an extra component. This ensures painless updatability and repairs and you have much less effort to remove specific files during an upgrade. In effect you get this best practice relation Feature 1  –> n Components Component   1  –>  1 Resources MSI Component Rules Rule 1 – One component per resource Every resource you want to install (file, registry key, value, environment value, shortcut, directory, …) must get its own component which does never change between versions as long as the install location is the same. Penalty If you add more than one resources to a component you will break the repair capability of MSI because the KeyPath is used to check if the component needs repair. MSI ComponentId Files MSI 1.0 {1000} File1-5 MSI 2.0 {2000} File2-5 You want to remove File1 in version 2.0 of your MSI. Since you want to keep the other files you create a new component and add them there. MSI will delete all files if the component refcount of {1000} drops to zero. The files you want to keep are added to the new component {2000}. Ok that does work if your upgrade does uninstall the old MSI first. This will cause the refcount of all previously installed components to reach zero which means that all files present in version 1.0 are deleted. But there is a faster way to perform your upgrade by first installing your new MSI and then remove the old one.  If you choose this upgrade path then you will loose File1-5 after your upgrade and not only File1 as intended by your new component design.   Rule 2 – Only add, never remove resources from a component If you did follow rule 1 you will not need Rule 2. You can add in a patch more resources to one component. That is ok. But you can never remove anything from it. There are tricky ways around that but I do not want to encourage bad component design. Penalty Lets assume you have 2 MSI files which install under the same component one file   MSI1 MSI2 {1000} - ComponentId {1000} – ComponentId File1.txt File2.txt   When you install and uninstall both MSIs you will end up with an installation where either File1 or File2 will be left. Why? It seems that MSI does not store the resources associated with each component in its internal database. Instead Windows will simply query the MSI that is currently uninstalled for all resources belonging to this component. Since it will find only one file and not two it will only uninstall one file. That is the main reason why you never can remove resources from a component!   Rule 3 Never Remove A Component From an Update MSI. This is the same as if you change the GUID of a component by accident for your new update package. The resulting update package will not contain all components from the previously installed package. Penalty When you remove a component from a feature MSI will set the feature state during update to Advertised and log a warning message into its log file when you did enable MSI logging. SELMGR: ComponentId '{2DCEA1BA-3E27-E222-484C-D0D66AEA4F62}' is registered to feature 'xxxxxxx, but is not present in the Component table.  Removal of components from a feature is not supported! MSI (c) (24:44) [07:53:13:436]: SELMGR: Removal of a component from a feature is not supported Advertised means that MSI treats all components of this feature as not installed. As a consequence during uninstall nothing will be removed since it is not installed! This is not only bad because uninstall does no longer work but this feature will also not get the required patches. All other features which have followed component versioning rules for update packages will be updated but the one faulty feature will not. This results in very hard to find bugs why an update was only partially successful. Things got better with Windows Installer 4.5 but you cannot rely on that nobody will use an older installer. It is a good idea to add to your update msiexec call MSIENFORCEUPGRADECOMPONENTRULES=1 which will abort the installation if you did violate this rule.

• Enforce SSIS naming conventions using BI-xPress

  - by jamiet

  A long long long time ago (in 2006 in fact) I published a blog post entitled Suggested Best Practises and naming conventions in which I suggested a bunch of acronyms that folks could use to prefix object names in their SSIS packages, thus allowing easier identification of those objects in log records, here is a sample of some of those suggestions: If you have adopted these naming conventions (and I am led to believe that a bunch of people have) then you might like to know that you can now check for adherence to these conventions using a tool called BI-xPress from Pragmatic Works. BI-xPress includes a feature called the Best Practices Analyzer that scans your packages and assess them according to some rules that you specify. In addition Pragmatic Works have made available a collection of these rules that adhere to the naming conventions I specified in 2006 You can download this collection however I recommend you first read the accompanying article that demonstrates the capabilities of the Best Practices Analyzer. Pretty cool stuff. @Jamiet

• Alien deletes .deb when converting from .rpm

  - by Andre

  I'm trying to convert .rpm to .deb using alien. sudo alien -k libtetra-1.0.0-2.i386.rpm Alien says that: libtetra-1.0.0-2.i386.deb generated But when I check the folder - there is just original .rpm and no .deb.

• How can I configure the Aiptek T-6000U graphics tablet?

  - by mejpark

  I followed AiptekTablet instructions on the Ubuntu Wiki to configure 11.04 for use with my graphics tablet. I installed the xserver-xorg-input-aiptek package and created two files with the options detailed on the Wiki page above: $ cat /lib/udev/rules.d/69-xserver-xorg-input-aiptek.rules ACTION!="add|change", GOTO="xorg_aiptek_end" KERNEL!="event[0-9]*", GOTO="xorg_aiptek_end" ATTRS{idVendor}=="08ca", ENV{x11_driver}="aiptek", SYMLINK+="input/aiptektablet" LABEL="xorg_aiptek_end" $ cat /usr/share/X11/xorg.conf.d/50-aiptek.conf Section "InputClass" Identifier "pen" MatchProduct "Aiptek|AIPTEK|aiptek" MatchDevicePath "/dev/input/event*" Driver "aiptek" Option "USB" "on" Option "Type" "stylus" Option "Mode" "absolute" Option "zMin" "0" Option "zMax" "511" EndSection The 50-aiptek.conf file was originally called 10-aiptek.conf as in the Wiki, but an Aiptek tablet installation help thread on the Ubuntu Forums, suggested changing 10 to 50. Any ideas? Thank you.

• Big Data – Evolution of Big Data – Day 3 of 21

  - by Pinal Dave

  In yesterday’s blog post we answered what is the Big Data. Today we will understand why and how the evolution of Big Data has happened. Though the answer is very simple, I would like to tell it in the form of a history lesson. Data in Flat File In earlier days data was stored in the flat file and there was no structure in the flat file.  If any data has to be retrieved from the flat file it was a project by itself. There was no possibility of retrieving the data efficiently and data integrity has been just a term discussed without any modeling or structure around. Database residing in the flat file had more issues than we would like to discuss in today’s world. It was more like a nightmare when there was any data processing involved in the application. Though, applications developed at that time were also not that advanced the need of the data was always there and there was always need of proper data management. Edgar F Codd and 12 Rules Edgar Frank Codd was a British computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases. He presented 12 rules for the Relational Database and suddenly the chaotic world of the database seems to see discipline in the rules. Relational Database was a promising land for all the unstructured database users. Relational Database brought into the relationship between data as well improved the performance of the data retrieval. Database world had immediately seen a major transformation and every single vendors and database users suddenly started to adopt the relational database models. Relational Database Management Systems Since Edgar F Codd proposed 12 rules for the RBDMS there were many different vendors who started them to build applications and tools to support the relationship between database. This was indeed a learning curve for many of the developer who had never worked before with the modeling of the database. However, as time passed by pretty much everybody accepted the relationship of the database and started to evolve product which performs its best with the boundaries of the RDBMS concepts. This was the best era for the databases and it gave the world extreme experts as well as some of the best products. The Entity Relationship model was also evolved at the same time. In software engineering, an Entity–relationship model (ER model) is a data model for describing a database in an abstract way. Enormous Data Growth Well, everything was going fine with the RDBMS in the database world. As there were no major challenges the adoption of the RDBMS applications and tools was pretty much universal. There was a race at times to make the developer’s life much easier with the RDBMS management tools. Due to the extreme popularity and easy to use system pretty much every data was stored in the RDBMS system. New age applications were built and social media took the world by the storm. Every organizations was feeling pressure to provide the best experience for their users based the data they had with them. While this was all going on at the same time data was growing pretty much every organization and application. Data Warehousing The enormous data growth now presented a big challenge for the organizations who wanted to build intelligent systems based on the data and provide near real time superior user experience to their customers. Various organizations immediately start building data warehousing solutions where the data was stored and processed. The trend of the business intelligence becomes the need of everyday. Data was received from the transaction system and overnight was processed to build intelligent reports from it. Though this is a great solution it has its own set of challenges. The relational database model and data warehousing concepts are all built with keeping traditional relational database modeling in the mind and it still has many challenges when unstructured data was present. Interesting Challenge Every organization had expertise to manage structured data but the world had already changed to unstructured data. There was intelligence in the videos, photos, SMS, text, social media messages and various other data sources. All of these needed to now bring to a single platform and build a uniform system which does what businesses need. The way we do business has also been changed. There was a time when user only got the features what technology supported, however, now users ask for the feature and technology is built to support the same. The need of the real time intelligence from the fast paced data flow is now becoming a necessity. Large amount (Volume) of difference (Variety) of high speed data (Velocity) is the properties of the data. The traditional database system has limits to resolve the challenges this new kind of the data presents. Hence the need of the Big Data Science. We need innovation in how we handle and manage data. We need creative ways to capture data and present to users. Big Data is Reality! Tomorrow In tomorrow’s blog post we will try to answer discuss Basics of Big Data Architecture.

• Gawker Passwords

  - by Nick Harrison

  There has been much news about the hack of the Gawker web sites. There has even been an analysis of the common passwords found. This list is embarrassing in many ways. The most common password was "123456". The second most common password was "password". Much has also been written providing advice on how to create good passwords. This article provides some interesting advice, none of which should be taken. Anyone reading my blog, probably already knows the importance of strong passwords, so I am not going to reiterate the reasons here. My target audience is more the folks defining password complexity requirements. A user cannot come up with a strong password, if we have complexity requirements that don't make sense. With that in mind, here are a few guidelines:  Long Passwords Insist on long passwords. In some cases, you may need to change to allow a long password. I have seen many places that cap passwords at 8 characters. Passwords need to be at least 8 characters minimal. Consider how much stronger the passwords would be if you double the length. Passwords that are 15-20 characters will be that much harder to crack. There is no need to have limit passwords to 8 characters. Don't Require Special Characters Many complexity rules will require that your password include a capital letter, a lower case letter, a number, and one of the "special" characters, the shits above the number keys. The problem with such rules is that the resulting passwords are harder to remember. It also means that you will have a smaller set of characters in the resulting passwords. If you must include one of the 9 digits and one of the 9 "special" characters, then you have dramatically reduced the character set that will make up the final password. Two characters will be one of 10 possible values instead of one of 70. Two additional characters will be one of 26 possible characters instead of a 70 character potential character set. If you limit passwords to 8 characters, you are left with only 7 characters having the full set of 70 potential values. With these character restrictions in place, there are 1.6 x1012 possible passwords. Without these special character restrictions, but allowing numbers and special characters, you get a total of 5.76x1014 possible passwords. Even if you only allowed upper and lower case characters, you will still have 2.18X1014 passwords. You can do the math any number of ways, requiring special characters will always weaken passwords. Now imagine the number of passwords when you require more than 8 characters.  If you are responsible for defining complexity rules, I urge you to take these guidelines into account. What other guidelines do you follow?

• Alien deletes .deb when converting from .rpm

  - by Stann

  I'm trying to convert .rpm to .deb using alien. sudo alien -k libtetra-1.0.0-2.i386.rpm Alien says that: libtetra-1.0.0-2.i386.deb generated But when I check the folder - there is just original .rpm and no .deb. Also - I can see that for a split second there is a .deb file in a folder. so it looks like alien create .deb and deletes it right away. I suspect that it's maybe because I run 64 bit os and package is 32? Can somebody explain why alien deletes .deb automatically?

• WIF, ADFS 2 and WCF&ndash;Part 3: ADFS Setup

  - by Your DisplayName here!

  In part 1 of this series I briefly gave an overview of the ADFS / WS-Trust infrastructure. In part 2 we created a basic WCF service that uses ADFS for authentication. This part will walk you through the steps to register the service in ADFS 2. I could provide screenshots for all the wizard pages here – but since this is really easy – I just go through the necessary steps in textual form. Step 1 – Select Data Source Here you can decide if you want to import a federation metadata file that describes the service you want to register. In that case all necessary information is inside the metadata document and you are done. FedUtil (a tool that ships with WIF) can generate such metadata for the most simple cases. Another tool to create metadata can be found here. We choose ‘Manual’ here. Step 2 – Specify Display Name I guess that’s self explaining. Step 3 – Choose Profile Choose ‘ADFS 2 Profile’ here. Step 4 – Configure Certificate Remember that we specified a certificate (or rather a private key) to be used to decrypting incoming tokens in the previous post. Here you specify the corresponding public key that ADFS 2 should use for encrypting the token. Step 5 – Configure URL This page is used to configure WS-Federation and SAML 2.0p support. Since we are using WS-Trust you can leave both boxes unchecked. Step 6 – Configure Identifier Here you specify the identifier (aka the realm, aka the appliesTo) that will be used to request tokens for the service. This value will be used in the token request and is used by ADFS 2 to make a connection to the relying party configuration and claim rules. Step 7 – Configure Issuance Authorization Rules Here you can configure who is allowed to request token for the service. I won’t go into details here how these rules exactly work – that’s for a separate blog post. For now simply use the “Permit all users” option. OK – that’s it. The service is now registered at ADFS 2. In the next part we will finally look at the service client. Stay tuned…

• Using IP Restrictions with URL Rewrite-Week 25

  - by OWScott

  URL Rewrite offers tremendous flexibility for customizing rules to your environment. One area of functionality that is often desired for URL Rewrite is to allow a large list of approved or denied IP addresses and subnet ranges. IIS’s original IP Restrictions is helpful for fully blocking an IP address, but it doesn’t offer the flexibility that URL Rewrite does. An example where URL Rewrite is helpful is where you want to allow only authorized IPs to access staging.yoursite.com, but where staging.yoursite.com is part of the same site as www.yoursite.com. This requires conditional logic for the user’s IP. This lesson covers this unique situation while also introducing Rewrite Maps, server variables, and pairing rules to add more flexibility. This is week 25 of a 52 week series for the Web Pro. Past and future videos can be found here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.
