• Announcing Windows Azure Mobile Services

  - by ScottGu

  I’m excited to announce a new capability we are adding to Windows Azure today: Windows Azure Mobile Services Windows Azure Mobile Services makes it incredibly easy to connect a scalable cloud backend to your client and mobile applications.  It allows you to easily store structured data in the cloud that can span both devices and users, integrate it with user authentication, as well as send out updates to clients via push notifications. Today’s release enables you to add these capabilities to any Windows 8 app in literally minutes, and provides a super productive way for you to quickly build out your app ideas.  We’ll also be adding support to enable these same scenarios for Windows Phone, iOS, and Android devices soon. Read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple Windows 8 “Todo List” app that is cloud enabled using Windows Azure Mobile Services.  Or watch this video of me showing how to do it step by step. Getting Started If you don’t already have a Windows Azure account, you can sign up for a no-obligation Free Trial.  Once you are signed-up, click the “preview features” section under the “account” tab of the www.windowsazure.com website and enable your account to support the “Mobile Services” preview.   Instructions on how to enable this can be found here. Once you have the mobile services preview enabled, log into the Windows Azure Portal, click the “New” button and choose the new “Mobile Services” icon to create your first mobile backend.  Once created, you’ll see a quick-start page like below with instructions on how to connect your mobile service to an existing Windows 8 client app you have already started working on, or how to create and connect a brand-new Windows 8 client app with it: Read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple Windows 8 “Todo List” app  that stores data in Windows Azure. Storing Data in the Cloud Storing data in the cloud with Windows Azure Mobile Services is incredibly easy.  When you create a Windows Azure Mobile Service, we automatically associate it with a SQL Database inside Windows Azure.  The Windows Azure Mobile Service backend then provides built-in support for enabling remote apps to securely store and retrieve data from it (using secure REST end-points utilizing a JSON-based ODATA format) – without you having to write or deploy any custom server code.  Built-in management support is provided within the Windows Azure portal for creating new tables, browsing data, setting indexes, and controlling access permissions. This makes it incredibly easy to connect client applications to the cloud, and enables client developers who don’t have a server-code background to be productive from the very beginning.  They can instead focus on building the client app experience, and leverage Windows Azure Mobile Services to provide the cloud backend services they require.  Below is an example of client-side Windows 8 C#/XAML code that could be used to query data from a Windows Azure Mobile Service.  Client-side C# developers can write queries like this using LINQ and strongly typed POCO objects, which are then translated into HTTP REST queries that run against a Windows Azure Mobile Service.   Developers don’t have to write or deploy any custom server-side code in order to enable client-side code below to execute and asynchronously populate their client UI: Because Mobile Services is part of Windows Azure, developers can later choose to augment or extend their initial solution and add custom server functionality and more advanced logic if they want.  This provides maximum flexibility, and enables developers to grow and extend their solutions to meet any needs. User Authentication and Push Notifications Windows Azure Mobile Services also make it incredibly easy to integrate user authentication/authorization and push notifications within your applications.  You can use these capabilities to enable authentication and fine grain access control permissions to the data you store in the cloud, as well as to trigger push notifications to users/devices when the data changes.  Windows Azure Mobile Services supports the concept of “server scripts” (small chunks of server-side script that executes in response to actions) that make it really easy to enable these scenarios. Below are some tutorials that walkthrough common authentication/authorization/push scenarios you can do with Windows Azure Mobile Services and Windows 8 apps: Enabling User Authentication Authorizing Users  Get Started with Push Notifications Push Notifications to multiple Users Manage and Monitor your Mobile Service Just like with every other service in Windows Azure, you can monitor usage and metrics of your mobile service backend using the “Dashboard” tab within the Windows Azure Portal. The dashboard tab provides a built-in monitoring view of the API calls, Bandwidth, and server CPU cycles of your Windows Azure Mobile Service.   You can also use the “Logs” tab within the portal to review error messages.  This makes it easy to monitor and track how your application is doing. Scale Up as Your Business Grows Windows Azure Mobile Services now allows every Windows Azure customer to create and run up to 10 Mobile Services in a free, shared/multi-tenant hosting environment (where your mobile backend will be one of multiple apps running on a shared set of server resources).  This provides an easy way to get started on projects at no cost beyond the database you connect your Windows Azure Mobile Service to (note: each Windows Azure free trial account also includes a 1GB SQL Database that you can use with any number of apps or Windows Azure Mobile Services). If your client application becomes popular, you can click the “Scale” tab of your Mobile Service and switch from “Shared” to “Reserved” mode.  Doing so allows you to isolate your apps so that you are the only customer within a virtual machine.  This allows you to elastically scale the amount of resources your apps use – allowing you to scale-up (or scale-down) your capacity as your traffic grows: With Windows Azure you pay for compute capacity on a per-hour basis – which allows you to scale up and down your resources to match only what you need.  This enables a super flexible model that is ideal for new mobile app scenarios, as well as startups who are just getting going.  Summary I’ve only scratched the surface of what you can do with Windows Azure Mobile Services – there are a lot more features to explore.  With Windows Azure Mobile Services you’ll be able to build mobile app experiences faster than ever, and enable even better user experiences – by connecting your client apps to the cloud. Visit the Windows Azure Mobile Services development center to learn more, and build your first Windows 8 app connected with Windows Azure today.  And read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple Windows 8 “Todo List” app that is cloud enabled using Windows Azure Mobile Services. 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

• SSH login very slow on OS X Leopard

  - by acjohnson55

  My SSH sessions take a very long time to initiate. This applies for logins with and without passwords, interactive and non-interactive. I have tried setting 'GSSAPIAuthentication no' and 'IPQoS 0x00' on the client side, and 'UseDNS no' on the server side, but no dice. I'm really stumped and frustrated. The worst part is that it SFTP takes forever to establish connections too, making file transfer much longer than it would be otherwise. I thought the problem might be something with PAM, because of where the hang is in the sshd log below, so I tried commenting out each line one-by-one in the /etc/pam.d/sshd file. Some caused login to be impossible, some had no apparent effect. I can't really tell if PAM is stalling for other services, but I can say that su'ing into my account from another account with 'su -l' has no apparent delay. I tried creating a new user account, just to see if there was something wrong with my existing account, and the same problem persisted. Any ideas of what's going on? On the client side, the most verbose mode outputs (redacted where reasonable): OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data ... debug1: ... line 1: Applying options for ... debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 53: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to ...

• Getting WCF Services in a Silverlight solution to play nice on deployment

  - by brendonpage

  I have come across 2 issues with deploying WCF services in a Silverlight solution, admittedly the one is more of a hiccup, and only occurs if you take the easy way out and reference your services through visual studio. The First Issue This occurs when you deploy your WFC services to an IIS server. When browse to the services using your web browser, you are greeted with “This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection.”. When you make a call to this service from your Silverlight application, you get the extremely helpful “NotFound” error, this error message can be found in the error property of the event arguments on the complete event handler for that call. As it did with me this will leave most people scratching their head, because the very same services work just fine on the ASP.NET Development Web Server and on my local IIS server. Now I’m no server/hosting/IIS expert so I did a bit of searching when I first encountered this issue. I found out this happens because IIS supports multiple address bindings per protocol (http/https/ftp … etc) per web site, but WCF only supports binding to one address per protocol. This causes a problem when the WCF service is hosted on a site with multiple address bindings, because IIS provides all of the bindings to the host factory when running the service. While this problem occurs mainly on shared hosting solutions, it is not limited to shared hosting, it just seems like all shared hosting providers setup sites on their servers with multiple address bindings. For interests sake I added functionality to the example project attached to this post to dump the addresses given to the WCF service by IIS into a log file. This was the output on the shared hosting solution I use: http://mydomain.co.za/Services/TestService.svc http://www.mydomain.co.za/Services/TestService.svc http://mydomain-co-za.win13.wadns.net/Services/TestService.svc http://win13/Services/TestService.svc As you can see all these addresses are for the http protocol, which is where it all goes wrong for WCF. Fixes for the First Issue There are a few ways to get around this. The first being the easiest, target .NET 4! Yes that's right in .NET 4 WCF services support multiple addresses per protocol. This functionality is enabled by an option, which is on by default if you create a new project, you will need to turn on if you are upgrading to .NET 4. To do this set the multipleSiteBindingsEnabled property of the serviceHostingEnviroment tag in the web.config file to true, as shown below: <system.serviceModel>     <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> </system.serviceModel> Beware this ONLY works in .NET 4, so if you don’t have a server with .NET 4 installed on that you can deploy to, you will need to employ one of the other work a rounds. The second option will work for .NET 3.5 & 4. For this option all you need to do is modify the web.config file and add baseAddressPrefixFilters to the serviceHostingEnviroment tag as shown below: <system.serviceModel>     <serviceHostingEnvironment>         <baseAddressPrefixFilters>              <add prefix="http://www.mydomain.co.za"/>         </baseAddressPrefixFilters>     </serviceHostingEnvironment> </system.serviceModel> These will be used to filter the list of base addresses that IIS provides to the host factory. When specifying these prefix filters be sure to specify filters which will only allow 1 result through, otherwise the entire exercise will be pointless. There is however a problem with this work a round, you are only allowed to specify 1 prefix filter per protocol. Which means you can’t add filters for all your environments, this will therefore add to the list of things to do before deploying or switching dev machines. The third option is the one I currently employ, it will work for .NET 3, 3.5 & 4, although it is not needed for .NET 4. For this option you create a custom host factory which inherits from the ServiceHostFactory class. In the implementation of the ServiceHostFactory you employ logic to figure out which of the base addresses, that are give by IIS, to use when creating the service host. The logic you use to do this is completely up to you, I have seen quite a few solutions that simply statically reference an index from the list of base addresses, this works for most situations but falls short in others. For instance, if the order of the base addresses where to change, it might end up returning an address that only resolves on the servers local network, like the last one in the example I gave at the beginning. Another instance, if a request comes in on a different protocol, like https, you will be creating the service host using an address which is on the incorrect protocol, like http. To reliably find the correct address to use, I use the address that the service was requested on. To accomplish this I use the HttpContext, which requires the service to operate with AspNetCompatibilityRequirements set on. If for some reason running you services with AspNetCompatibilityRequirements on isn’t an option, you can still use this method, you will just have to come up with your own logic for selecting the correct address. First you will need to enable AspNetCompatibilityRequirements for your hosting environment, to do this you will need to set it to true in the web.config file as shown below: <system.serviceModel>     <serviceHostingEnvironment AspNetCompatibilityRequirements="true" /> </system.serviceModel> You will then need to mark any services that are going to use the custom host factory, to allow AspNetCompatibilityRequirements, as shown below: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class TestService { } Now for the custom host factory, this is where the logic lives that selects the correct address to create service host with. The one i use is shown below: public class CustomHostFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { // // Compose a prefix filter based on the requested uri // string prefixFilter = HttpContext.Current.Request.Url.Scheme + "://" + HttpContext.Current.Request.Url.DnsSafeHost; if (!HttpContext.Current.Request.Url.IsDefaultPort) { prefixFilter += ":" + HttpContext.Current.Request.Url.Port.ToString() + "/"; } // // Find a base address that matches the prefix filter // foreach (Uri baseAddress in baseAddresses) { if (baseAddress.OriginalString.StartsWith(prefixFilter)) { return new ServiceHost(serviceType, baseAddress); } } // // Throw exception if no matching base address was found // throw new Exception("Custom Host Factory: No base address matching '" + prefixFilter + "' was found."); } } The most important line in the custom host factory is the one that returns a new service host. This has to return a service host that specifies only one base address per protocol. Since I filter by the address the request came on in, I only need to create the service host with one address, since this address will always be of the correct protocol. Now you have a custom host factory you have to tell your services to use it. To do this you view the markup of the service by right clicking on it in the solution explorer and choosing “View Markup”. Then you add/set the value of the Factory property to the full namespace path of you custom host factory, as shown below. And that is it done, the service will now use the specified custom host factory. The Second Issue As I mentioned earlier this issue is more of a hiccup, but I thought worthy of a mention so I included it. This issue only occurs when you add a service reference to a Silverlight project. Visual Studio will generate a lot of code for you, part of that generated code is the ServiceReferences.ClientConfig file. This file stores the endpoint configuration that is used when accessing your services using the generated proxy classes. Here is what that file looks like: <configuration>     <system.serviceModel>         <bindings>             <customBinding>                 <binding name="CustomBinding_TestService">                     <binaryMessageEncoding />                     <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />                 </binding>                 <binding name="CustomBinding_BrokenService">                     <binaryMessageEncoding />                     <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />                 </binding>             </customBinding>         </bindings>         <client>             <endpoint address="http://localhost:49347/services/TestService.svc"                 binding="customBinding" bindingConfiguration="CustomBinding_TestService"                 contract="TestService.TestService" name="CustomBinding_TestService" />             <endpoint address="http://localhost:49347/Services/BrokenService.svc"                 binding="customBinding" bindingConfiguration="CustomBinding_BrokenService"                 contract="BrokenService.BrokenService" name="CustomBinding_BrokenService" />         </client>     </system.serviceModel> </configuration> As you will notice the addresses for the end points are set to the addresses of the services you added the service references from, so unless you are adding the service references from your live services, you will have to change these addresses before you deploy. This is little more than an annoyance really, but it adds to the list of things to do before you can deploy, and if left unchecked that list can get out of control. Fix for the Second Issue The way you would usually access a service added this way is to create an instance of the proxy class like so: BrokenServiceClient proxy = new BrokenServiceClient(); Closer inspection of these generated proxy classes reveals that there are a few overloaded constructors, one of which allows you to specify the end point address to use when creating the proxy. From here all you have to do is come up with some logic that will provide you with the relative path to your services. Since my WCF services are usually hosted in the same project as my Silverlight app I use the class shown below: public class ServiceProxyHelper { /// <summary> /// Create a broken service proxy /// </summary> /// <returns>A broken service proxy</returns> public static BrokenServiceClient CreateBrokenServiceProxy() { Uri address = new Uri(Application.Current.Host.Source, "../Services/BrokenService.svc"); return new BrokenServiceClient("CustomBinding_BrokenService", address.AbsoluteUri); } } Then I will create an instance of the proxy class using my service helper class like so: BrokenServiceClient proxy = ServiceProxyHelper.CreateBrokenServiceProxy(); The way this works is “Application.Current.Host.Source” will return the URL to the ClientBin folder the Silverlight app is hosted in, the “../Services/BrokenService.svc” is then used as the relative path to the service from the ClientBin folder, combined by the Uri object this gives me the URL to my service. The “CustomBinding_BrokenService” is a reference to the end point configuration in the ServiceReferences.ClientConfig file. Yes this means you still need the ServiceReferences.ClientConfig file. All this is doing is using a different end point address than the one specified in the ServiceReferences.ClientConfig file, all the other settings form the ServiceReferences.ClientConfig file are still used when creating the proxy. I have uploaded an example project which covers the custom host factory solution from the first issue and everything from the second issue. I included the code to write a list of base addresses to a log file in my implementation of the custom host factory, this is not need for the custom host factory to function and can safely be removed.

• Loading JNI lib on OSX?

  - by Clinton

  Background So I am attempting to load a jnilib (specifically JOGL) into java on OSX at runtime. I have been following along the relevant stackoverflow questions: Maven and the JOGL Library Loading DLL in Java - Eclipse - JNI How to make a jar file that include all jar files The end goal for me is to package platform specific JOGL files into a jar and unzip them into a temp directory and load them at start-up. I worked my problem back to simply attempting to load JOGL using hard-coded paths: File f = new File("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl.jnilib"); System.load(f.toString()); f = new File ("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl_awt.jnilib"); System.load(f.toString()); I get the following exception when attempting to use the JOGL API: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path But when I specify java.library.path by adding the following JVM option: -Djava.library.path="/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/" Everything works fine. Question Is it possible use System.load (or some other variant) on OSX as a replacement for -Djava.library.path that is invoked at runtime?

• Getting SSL to work with Apache/Passenger on OSX

  - by jonnii

  I use apache/passenger on my development machine, but need to add SSL support (something which isn't exposed through the control panel). I've done this before in production, but for some reason I can't seem to get it work on OSX. The steps I've followed so far are from a default apache osx install: Install passenger and passenger preference pane. Add my rails app (this works) Create my ca.key, server.crt and server.key as detailed on the apple website. At this point I need to start editing the apache configs, so I added: # Apache knows to listen on port 443 for ssl requests. Listen 443 Listen 80 I thought I'd try editing the passenger pref pane generated config first to get everything working, when I add: It starts off looking like this <VirtualHost *:80> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <Directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </Directory> </VirtualHost> I then append this: <VirtualHost *:443> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </directory> # SSL Configuration SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP SSLOptions +FakeBasicAuth +ExportCertData +StdEnvVars +StrictRequire #Self Signed certificates SSLCertificateFile /private/etc/apache2/ssl.key/server.crt SSLCertificateKeyFile /private/etc/apache2/ssl.key/server.key SSLCertificateChainFile /private/etc/apache2/ssl.key/ca.crt SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 </VirtualHost> The files referenced all exist (I doubled checked that), but now when I restart my apache I can't even get to myapp.local. However apache can still server the default page when I click on it in the sharing preference panel. Any help would be greatly appreciated.

• SL3/SL4 - Ado.Net Data Services Error during new DataServiceCollection<T>(queryResponse)

  - by Soulhuntre

  Hey all, I have two functions in a SL project (VS2010) that do almost exactly the same thing, yet one throws an error and the other does not. It seems to be related to the projections, but I am unsure about the best way to resolve. The function that works is... public void LoadAllChunksExpandAll(DataHelperReturnHandler handler, string orderby) { DataServiceCollection<CmsChunk> data = null; DataServiceQuery<CmsChunk> theQuery = _dataservice .CmsChunks .Expand("CmsItemState") .AddQueryOption("$orderby", orderby); theQuery.BeginExecute( delegate(IAsyncResult asyncResult) { _callback_dispatcher.BeginInvoke( () => { try { DataServiceQuery<CmsChunk> query = asyncResult.AsyncState as DataServiceQuery<CmsChunk>; if (query != null) { //create a tracked DataServiceCollection from the result of the asynchronous query. QueryOperationResponse<CmsChunk> queryResponse = query.EndExecute(asyncResult) as QueryOperationResponse<CmsChunk>; data = new DataServiceCollection<CmsChunk>(queryResponse); handler(data); } } catch { handler(data); } } ); }, theQuery ); } This compiles and runs as expected. A very, very similar function (shown below) fails... public void LoadAllPagesExpandAll(DataHelperReturnHandler handler, string orderby) { DataServiceCollection<CmsPage> data = null; DataServiceQuery<CmsPage> theQuery = _dataservice .CmsPages .Expand("CmsChildPages") .Expand("CmsParentPage") .Expand("CmsItemState") .AddQueryOption("$orderby", orderby); theQuery.BeginExecute( delegate(IAsyncResult asyncResult) { _callback_dispatcher.BeginInvoke( () => { try { DataServiceQuery<CmsPage> query = asyncResult.AsyncState as DataServiceQuery<CmsPage>; if (query != null) { //create a tracked DataServiceCollection from the result of the asynchronous query. QueryOperationResponse<CmsPage> queryResponse = query.EndExecute(asyncResult) as QueryOperationResponse<CmsPage>; data = new DataServiceCollection<CmsPage>(queryResponse); handler(data); } } catch { handler(data); } } ); }, theQuery ); } Clearly the issue is the Expand projections that involve a self referencing relationship (pages can contain other pages). This is under SL4 or SL3 using ADONETDataServices SL3 Update CTP3. I am open to any work around or pointers to goo information, a Google search for the error results in two hits, neither particularly helpful that I can decipher. The short error is "An item could not be added to the collection. When items in a DataServiceCollection are tracked by the DataServiceContext, new items cannot be added before items have been loaded into the collection." The full error is...

• Remote Desktop Services Gateway Issue

  - by AVandelay05

  Alright fellow techies here's the rundown. I have installed Server 2008 r2 Remote Dekstop Services on a VM in my network. I installed the following RD role services: RD Session Host, Licensing, Connection Broker, Gateway, Web Access. When I set things up originally, the gateway server and RDWeb worked as it should locally. After getting things running locally (remoteserver.domainname.local) I wanted to test things externally. From the outside, I couldn't get things running (meaning I could connect to rdweb access externally, but when I tried to run an app I would get the message "can't connect/find computer"). Here's my setup for external access The VM has every RD Services role services installed on it, meaning it acts as gateway, rd web access, session host, licensing, the whole bit. I made a self-signed certificate on the gateway server (gateway.domainname.net is the cert name). Internally, I have a secondary forward-lookup zone called domainname.net with an A record gateway pointing to the local IP of the gateway server. On our public DNS (domainname.net) I have an A record gateway. This is to access the RDWeb externally. In IIS I have the following authentication settings RDWeb: All disabled except for anonymous authentication Rpc: All disabled except for basic and windows RpcWithCert: All disbled except for windows authentication I have the necessary web access config in our sonicwall tz210 (https and rdp, external ip pointing to local ip of rds server) RAP and CAP have the correct user and computer groups, authentication, and allowed devices After all of this, here's what happens accessing externally. I can login correctly to RDWeb Access (I've tried a bogus login, I can't login to it so that's working properly). I see the Apps for use. I click on an app, click connect, the credential window opens, I put in the correct user creds, it tries to connect to the gateway server, but then the cred window comes back in view. I tried to reach a limit of failed logins, but never reached one, haha. So from the same external client machine I try to connect to the gateway through a Remote Desktop connection. I put in the correct gateway settings in the RD window, try to connect and get the same results as I did in RDWeb access. I checked the event logs on the RD Services machine and saw the following event IDs around the time I tried to login externally: ID 6037 with the message "The program svchost.exe, with the assigned process ID 2168, could not authenticate locally by using the target name host/gateway.domainname.net. The target name used is not valid. A target name should refer to one of the local computer names, for example, the DNS host name. Try a different target name." ID 10 RADWebAccess "RD Web Access was unable to access gateway.domainname.net, which is the server that is specified as running the RemoteApp and Desktop Connection Management service. Ensure that the computer account of the RD Web Access server is a member of the TS Web Access Computers security group on gateway.domainname.net" ID 4625 "An account failed to log on. Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: Administrator Account Domain: gateway.domainname.net Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc000006a Process Information: Caller Process ID: 0x0 Caller Process Name: - Network Information: Workstation Name: USER-LAPTOP Source Network Address: External IP Source Port: 63125 Detailed Authentication Information: Logon Process: NtLmSsp Authentication Package: NTLM Transited Services: - Package Name (NTLM only): - Key Length: 0 This event is generated when a logon request fails. It is generated on the computer where access was attempted. The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network). The Process Information fields indicate which account and process on the system requested the logon. The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols." I don't think the VM has a null SID. The SID of the VM and it's physical host have different SIDS. I can access the blank page for rpc externally using the external gateway name. It seems like authentication is a problem. Also, is it a problem that the external name of the gateway server doesn't match the local name? The external name (which the cert is based on) is gateway.domainname.net and the internal name is remoteserver.domainname.local. That's the only thing I can think of that would be the problem, but the external name has to be different from the local right? Internally, I ping gateway.domainname.net and it gives me the correct local IP of the server. Now, there isn't an actual computer name in AD, but I don't know how I would achieve that? I hope I've been clear....any help would be appreciated. I think I'm close to achieving this. :)

• 4GB of RAM in MacOSX 10.5, only 3GB in MacOSX 10.6

  - by Albert

  Hi, I was using MacOSX 10.5 on my MacBook until today and I had 4GB of memory there. Now I have updated to MacOSX 10.6 and it only displays 3GB. Why is that? How can I fix it? Also, I am a bit wondering why most people (well, most of the Google hits explained the 3GB issue that way -- leaving out the fact that it has worked earlier) are saying that a 32bit system can under no circumstances access more than 3.2GB. Don't we have PAE nowadays in most systems? Thanks, Albert

• Advantages of Mac OS X Server over Mac OS X Client?

  - by Donald Hughes

  I'm debating buying a mac mini with the regular client OS or the model with the server os for the purposes of replacing my home server. Are there any advantages for such a use with the server os?

• Mac OS can't connect to SMB shares after sleep

  - by Andreas

  I used to access my local Windows 2008 file server's SMB shares on my recent (3 weeks old) MacBook Pro without problems. However, for a few days now, it fails to (re-)connect to the server after it woke up from sleep mode. Finder just shows "connecting..." and hangs indefinitely. The same thing happens when I try it from the command line (mount -t smbfs). This happens via both WiFi and cable, I also tried turning networking off and back on. The only thing that helps is a reboot. Any hints?

• Mac does not recognize wide screen

  - by DUKE

  I am using Mac OS X Lion 10.7.4 on my Mac mini, with Samsung monitor with default resolution 1360 x 768. My Mac mini is connected to Samsung VGA port by Apple mini port to VGA adapter. When starting, my Mac does not recognize the wide screen resolution and always starts in a 4:3 mode, (but it shows 1360x768 as the resolution in the settings). I have to do one of the following actions to bring my Mac to the wide screen resolution: (1) Changing to some other resolution and bring back to the default resolution. (2) Unplug the Apple mini port to VGA adapter and re-connect again. (3) Put the machine to sleep and wake it up again. I am using Ubuntu 12.04, (in a different partition) in the same hardware, but Ubuntu is perfectly recognizing the display.

• OS X not booting after upgrading LibXML2

  - by Federico

  I tried upgrading the version of LibXML2 in my machine to run some propietary software. Compiled as 32-bit (-arch i386) and restarted to see if it worked. Now when I try to boot I can only get into the spinning screen and it just sits there. Restarting in verbose mode (Cmd-V) does not show any error in the process, it just freezes after "AppleIntelCPUPowerManagement: initialization complete". I can't from any CD either (if I press c on startup it just spins the disk around and then stops in the same spinner screen). I've also reset the PRAM/NVRAM to discard any problems with that and it´s still not fixed. Any pointers of what might´ve gone wrong? (Latest gen MBP, running 10.6.3)

• What free space thresholds/limits are advisable for 640 GB and 2 TB hard disk drives with ZEVO ZFS on OS X?

  - by Graham Perrin

  Assuming that free space advice for ZEVO will not differ from advice for other modern implementations of ZFS … Question Please, what percentages or amounts of free space are advisable for hard disk drives of the following sizes? 640 GB 2 TB Thoughts A standard answer for modern implementations of ZFS might be "no more than 96 percent full". However if apply that to (say) a single-disk 640 GB dataset where some of the files most commonly used (by VirtualBox) are larger than 15 GB each, then I guess that blocks for those files will become sub optimally spread across the platters with around 26 GB free. I read that in most cases, fragmentation and defragmentation should not be a concern with ZFS. Sill, I like the mental picture of most fragments of a large .vdi in reasonably close proximity to each other. (Do features of ZFS make that wish for proximity too old-fashioned?) Side note: there might arise the question of how to optimise performance after a threshold is 'broken'. If it arises, I'll keep it separate. Background On a 640 GB StoreJet Transcend (product ID 0x2329) in the past I probably went beyond an advisable threshold. Currently the largest file is around 17 GB –  – and I doubt that any .vdi or other file on this disk will grow beyond 40 GB. (Ignore the purple masses, those are bundles of 8 MB band files.) Without HFS Plus: the thresholds of twenty, ten and five percent that I associate with Mobile Time Machine file system need not apply. I currently use ZEVO Community Edition 1.1.1 with Mountain Lion, OS X 10.8.2, but I'd like answers to be not too version-specific. References, chronological order ZFS Block Allocation (Jeff Bonwick's Blog) (2006-11-04) Space Maps (Jeff Bonwick's Blog) (2007-09-13) Doubling Exchange Performance (Bizarre ! Vous avez dit Bizarre ?) (2010-03-11) … So to solve this problem, what went in 2010/Q1 software release is multifold. The most important thing is: we increased the threshold at which we switched from 'first fit' (go fast) to 'best fit' (pack tight) from 70% full to 96% full. With TB drives, each slab is at least 5GB and 4% is still 200MB plenty of space and no need to do anything radical before that. This gave us the biggest bang. Second, instead of trying to reuse the same primary slabs until it failed an allocation we decided to stop giving the primary slab this preferential threatment as soon as the biggest allocation that could be satisfied by a slab was down to 128K (metaslab_df_alloc_threshold). At that point we were ready to switch to another slab that had more free space. We also decided to reduce the SMO bonus. Before, a slab that was 50% empty was preferred over slabs that had never been used. In order to foster more write aggregation, we reduced the threshold to 33% empty. This means that a random write workload now spread to more slabs where each one will have larger amount of free space leading to more write aggregation. Finally we also saw that slab loading was contributing to lower performance and implemented a slab prefetch mechanism to reduce down time associated with that operation. The conjunction of all these changes lead to 50% improved OLTP and 70% reduced variability from run to run … OLTP Improvements in Sun Storage 7000 2010.Q1 (Performance Profiles) (2010-03-11) Alasdair on Everything » ZFS runs really slowly when free disk usage goes above 80% (2010-07-18) where commentary includes: … OpenSolaris has changed this in onnv revision 11146 … [CFT] Improved ZFS metaslab code (faster write speed) (2010-08-22)

• Snow Leopard doesn't repair permissions, despite showing / saying its fixed them?

  - by Jules

  Sometime ago, I used carbon copy as I was replacing my hard drive in my Mac Mini running Snow Leopard. Afterwards, on my new drive I had some permission problems. I've tried several times running a repair permissions / repair disk from disk util. It shows that there are problems and I think it says its correceted the problems. However the problems remain, what can I do to fix them ?

• How do I install ant on OS X Mavericks?

  After upgrading to OS X 10.9 Mavericks, ant is no longer on my path.

• What’s the password for my FileVault 2 boot volume?

  - by cbowns

  Apple’s support document for FileVault 2 (a.k.a. “full disk encryption” or “FDE”) has lots of information about enabling FDE and what it means for booting the machine. However, it doesn’t cover one very important thing I’m trying to do: mount the drive in the Recovery HD environment to reinstall OS X on it. The Recovery HD environment asks me for the volume passphrase so it can mount my drive and try to install OS X onto it. If this were an external drive which I’d manually enabled FDE on with diskutil, or an external Time Machine volume, I’d know it because it makes you pick one (just like a regular login password), but FileVault 2 never asked me for a volume passphrase (I assume it selects one behind the scenes). I’ve tried my main user’s password, but that doesn’t work, and neither does the recovery key set for the volume. Keychain Access doesn’t have anything that I could find. How do I unlock this volume?

• Permissions restoring from Time Machine - Finder copy vs "cp" copy

  - by Ben Challenor

  Note: this question was starting to sprawl so I rewrote it. I have a folder that I'm trying to restore from a Time Machine backup. Using cp -R works fine, but certain folders cannot be restored with either the Time Machine UI or Finder. Other users have reported similar errors and the cp -R workaround was suggested (e.g. Restoring from Time Machine - Permissions Error). But I wanted to understand: Why cp -R works when the Finder and the Time Machine UI do not. Whether I could prevent the errors by changing file permissions before the backup. There do indeed seem to be some permissions that Finder works with and some that it does not. I've narrowed the errors down to folders with the user ben (that's me) and the group wheel. Here's a simplified reproduction. I have four folders with the owner/group combinations I've seen so far: ben ~/Desktop/test $ ls -lea total 16 drwxr-xr-x 7 ben staff 238 27 Nov 14:31 . drwx------+ 17 ben staff 578 27 Nov 14:29 .. 0: group:everyone deny delete -rw-r--r--@ 1 ben staff 6148 27 Nov 14:31 .DS_Store drwxr-xr-x 3 ben staff 102 27 Nov 14:30 ben-staff drwxr-xr-x 3 ben wheel 102 27 Nov 14:30 ben-wheel drwxr-xr-x 3 root admin 102 27 Nov 14:31 root-admin drwxr-xr-x 3 root wheel 102 27 Nov 14:31 root-wheel Each contains a single file called file with the same owner/group: ben ~/Desktop/test $ cd ben-staff ben ~/Desktop/test/ben-staff $ ls -lea total 0 drwxr-xr-x 3 ben staff 102 27 Nov 14:30 . drwxr-xr-x 7 ben staff 238 27 Nov 14:31 .. -rw-r--r-- 1 ben staff 0 27 Nov 14:30 file In the backup, they look like this: ben /Volumes/Deimos/Backups.backupdb/Ben’s MacBook Air/Latest/Macintosh HD/Users/ben/Desktop/test $ ls -leA total 16 -rw-r--r--@ 1 ben staff 6148 27 Nov 14:34 .DS_Store 0: group:everyone deny write,delete,append,writeattr,writeextattr,chown drwxr-xr-x@ 3 ben staff 102 27 Nov 14:51 ben-staff 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown drwxr-xr-x@ 3 ben wheel 102 27 Nov 14:51 ben-wheel 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown drwxr-xr-x@ 3 root admin 102 27 Nov 14:52 root-admin 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown drwxr-xr-x@ 3 root wheel 102 27 Nov 14:52 root-wheel 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown Of these, ben-staff can be restored with Finder without errors. root-wheel and root-admin ask for my password and then restore without errors. But ben-wheel does not prompt for my password and gives the error: The operation can’t be completed because you don’t have permission to access “file”. Interestingly, I can restore the file from this folder by dragging it directly to my local drive (instead of dragging its parent folder), but when I do so its permissions are changed to ben/staff. Here are the permissions after the restore for the three folders that worked correctly, and the file from ben-wheel that was changed to ben/staff. ben ~/Desktop/test-restore $ ls -leA total 16 -rw-r--r--@ 1 ben staff 6148 27 Nov 14:46 .DS_Store drwxr-xr-x 3 ben staff 102 27 Nov 14:30 ben-staff -rw-r--r-- 1 ben staff 0 27 Nov 14:30 file drwxr-xr-x 3 root admin 102 27 Nov 14:31 root-admin drwxr-xr-x 3 root wheel 102 27 Nov 14:31 root-wheel Can anyone explain this behaviour? Why do Finder and the Time Machine UI break with the ben / wheel permissions? And why does cp -R work (even without sudo)?

• Dashboard Devmode w/o "Always on Top" Possible?

  - by Travis

  I am using (and loving) OS X's Dashboard in dev mode ('defaults write com.apple.dashboard devmode YES') which lets you put the widgets on your desktop directly. The only downside is the widgets are "always on top". So all windows end up going under the widgets instead of above. Is there any way to disable this?

• Persistent static routes fail on MacOS 10.6.5 startup!

  - by verbalicious

  I'm unable to get static routes to persist a reboot on Mac OS 10.6.5. I've tried all of the methods prescribed in Google search results, and previous posts on this site. I've tried manually creating a launchd daemon, and used RouteSplit's launchd daemon to no avail. It's clear that the interface is not ready when these methods attempt to apply the route. This workstation in question is getting its IP from DHCP and probably hasn't gotten its DHCP lease when the command runs. We're able to apply the route by hand when logged in, but not through startup methods. Is there another way to apply this route by sneaking the command into something later, but before the login window appears to the user? Here is some relevant log info from system.log. You can see the "route: writing to routing socket: Network is unreachable" errors where my launchd script fires off. I've tried adding extra "sleep" and "ipconfig waitall" statements later in the script but this doesn't fly.

• Mac OS X Update 10.6.8 weird phishing behaviour

  I just updated to Mac App Store 1.0.2 with the update to 10.6.8. The Mac App Store said I have one update available, for Angry Birds.... I do not have Angry Birds on my system, but when I clicked the update button I got the following message. "You have updates available for other accounts. Sign in to [email protected] to update applications for that account." Needless to say this account does not exist. Any ideas what this is all about?

• Exchange Public Folders in Snow Leopard Mail.app

  - by Paul

  I am using Mail.app (running snow leopard) to connect to my email account on my school's Exchange 2007 server. I get my Inbox just fine, and iCal connects to my Outlook Calendar just fine, but I cannot seem to get any of the Exchange Public Folders that I can automatically see when I am using Outlook on a Windows box. The Account Type is shown as "Exchange 2007" I did not have any luck Googling this problem, in fact most of the results I saw were dealing with the opposite problem: Remove MS Exchange Public Folders I am aware that my question is a duplicate of this: http://superuser.com/questions/103115/apple-mail-app-all-exchange-folders-not-visible but since that question did not get any responses, I am reposting.
