• correct file permissions for trac and git user to access gitolite server repos

  - by klemens

  hi, sounds like a stupid questions (to me), but i couldn't find any info. on my server i host some git repositories via gitolite, and have a trac for every repository. i have a user called git to push/pull from server (git clone git@server:repo). and trac is a apache vhost with mod_wsgi. this runs with the www-data user. so what riddles me (maybe because I have not much of a clue about file-permissions at all) is whats the best permissions setup (chown, chmod) for the git repositories (/home/git/repositories/...). www-data (or trac) needs to at least read permissions (i think). and git (or gitolite) needs obviously read/write permissions to push changesets. i tried a little bit around (i.e. adding www-data and/or git to the www-data/git group), but didn't got it right. at least one of the two don't work (git or trac). any suggestions are highly appreciated. regard, klemens

• Authenticate domain-user credentials on unjoined virtual machine?

  - by bwerks

  Hi all, This question may sound silly, and perhaps a bit insane, but--is there any way to run a process on a machine not joined to a domain using credentials from a user in that domain? In my case, I'm running virtual machines installed with release binaries from our build process, as well as Visual Studio. Visual Studio is there to debug our release binaries, however it's being executed with vm-local user credentials. This means that it can't authenticate to our TFS deployment when executing "tf.exe view" to utilize our Source Server for debugging. Team Explorer manages to authenticate to TFS using a UI prompt, however I suspect that it's because we supply it with the TFS deployment's URI, and it's designed to display a prompt to facilitate workgroup scenarios; i.e. it's not like we're getting it for free. My instincts tell me the only way to authenticate on this vm is to join it or somehow form a one-way trust or something, but is there an easier way? For automation we're going to want to script this eventually, but I'm first surveying the feasibility of the thing.

• NetBackup's bplist doesn't get user/group info for Windows files

  - by Gnustavo

  I'm trying to get information about storage consumption from NetBackup's bplist output. I'm running NBU 6.0MP5 on a RHEL 3 server. The server is backing up several Solaris, Linux, and Windows machines. When I use bplist to get information about files backed up on any UNIX machine I get something like this: # bplist -C unixclient -R 99 -l -s 01/28/2006 -e 01/29/2006 / drwxr-xr-x test ccase 0 Nov 16 09:28 /l/home2/test/ -rw------- test ccase 4737 Jan 06 17:54 /l/home2/test/.bash_history -rw-rw-r-- test ccase 104 Nov 11 2004 /l/home2/test/.bashrc However, when I use it to list files backed up on any Windows client I can't get the user and group information. They both always appear as 'root'. Like this: # bplist -C winclient -t 13 -R 99 -l -s 02/20/2006 / drwx------ root root 0 Feb 20 14:26 /C/temp/ -rwx------ root root 41 Feb 20 14:26 /C/temp/asdf.txt drwx------ root root 0 May 25 2004 /C/temp/CTRMNGR/ Does anyone know why bplist doesn't show the correct user/group for Windows files? If it can't, is there a way to get that information using another command? Thanks. Gustavo.

• A tale of two user ids: Why does NFS not recognize a new user id?

  - by user76177

  I have two servers running RHEL6. The main server, which I will refer to as server, is a database server. The application server, which I will refer to as client, mounts a directory from server via NFS. There is a user, appuser, on both client and server. However, appuser's id on client is 502. appuser's id on server is 506. Both users need read and write capability on the NFS share. To facilitate this, I made the share owned by appuser on server. Of course, client does not recognize that ownership, since appuser has a different id on client. So I did the following: Changed id of user in /etc/passwd on client to be 506 **Changed ownership of appuser's $HOME on client to be appuser again so that I could log in. Now, when I go to look at the NFS share from the client side, I see that it is owned by 502. 502 is the OLD id for appuser on client. I can't change ownership of the NFS share from client, since that is a volume that physically resides on server. I need to make sure that the NFS share shows ownership of appuser from both server and client. What step have I missed since changing the appuser id on client? NOTE: I have not rebooted client or done anything else yet.

• Change Windows Authentication user for Sql Server Management Studio

  - by Asmor

  We're using Sql Server 2005 with Windows Authentication setup. So normally, when you log in using e.g. Sql Server Management Studio, it forces you to log in at MACHINE_NAME\Username. Anyways, on this one particular computer, the person said they had to make a new account called User01 to do something and showed me where she'd created it under security in the "master" system database. And so now when she logs in, it's listed as MACHINE_NAME\User01 (not the actual Windows user name). It's still set to Windows Authentication, though, and I'm unable to change the login name. Now here's where the real problem comes in... I didn't realize that she was being logged in under this user name at the time, and I disabled it to see what would happen. Now I can't log into the server under her account. I created a new account in Windows called test, and as expected SSMS had the username as MACHINE_NAME\test, and I was able to log in fine. However, the area where the User01 account was listed is not visible to me as far as I can tell and so I can't reenable it. I also tried running the following query: alter login User01 ENABLE And got this error: Msg 15151, Level 16, State 1, Line 1 Cannot alter the login 'User01', because it does not exist or you do not have permission. So in a nutshell, ideally I'd like to reenable User01 somehow, just to get things back to where they used to be. Failing that, how can I force SSMS to log in using the Windows account name as it should be, rather than trying to use User01?

• Run a script on user connection on the VM host

  - by Scott Chamberlain

  I have a server running a Virtual Desktop Managed Pool, what I would like to do is when a user logs in I would like a script to check the number of available VMs and if below a threashold add additional VMs to the pool. The script to check the load and add to the pool is not the problem, I have that already figured out: $collectionName = "Test1"; $rdvh = "vmHost.example.com"; $minAvailableVMs = 2; Import-Module RemoteDesktop; $pool = Get-VirtualDesktopCollection -CollectionName $collectionName; $availableVMs = $pool.Size - ($pool.Size * $pool.PercentInUse / 100); $status = Get-VirtualDesktopCollectionJobStatus $collectionName #only add new servers if we are below the threashold and in the JOB_COMPLETEED state if($availableVMs -lt $minAvailableVMs -and $status.Status -eq [Microsoft.RemoteDesktopServices.Management.VirtualDesktopCollectionJobStatus]::JOB_COMPLETED) { Add-RDVirtualDesktopToCollection -CollectionName $collectionName -VirtualDesktopAllocation @{"$rdvh" = 1} } The problem I am having is, how do I run the above script on the Virtualization Host/Connection Broker/Some other server when a user connects?. I don't think it would be appropriate to run this as a logon script inside the VM, I think there is a way to do this on the management side but I don't know the new scripting interface in Server 2012 R2 well enough to know which commandlets I should look for to schedule this. EDIT: I know System Center is perfect for this but I do not have a license and was denied when I asked for it to be added to the budget.

• script to list user's mapped drive not giving results or error

  - by user223631

  We are in the process of migrating two file servers to a new server. We have mapped drives via user group in group policy. Many users have manually mapped drives and we need to find these mappings. I have created a PowerShell script to run that remotely get the drive mappings. It works on most computers but there are many that are not returning results and I am not getting any error messages. Each workstation on the list creates a text file and the ones that are not returning results have no text in the files. I can ping these machines. If the machine is not turned on, it does come up error message that the RPC server is not available. My domain user account is in a group that is in the local admin account. I have no idea why some are not working. Here is the script. # Load list into variable, which will become an array of strings If( !(Test-Path C:\Scripts)) { New-Item C:\Scripts -ItemType directory } If( !(Test-Path C:\Scripts\Computers)) { New-Item C:\Scripts\Computers -ItemType directory } If( !(Test-Path C:\Scripts\Workstations.txt)) { "No Workstations found. Please enter a list of Workstations under Workstation.txt"; Return} If( !(Test-Path C:\Scripts\KnownMaps.txt)) { "No Mapping to check against. Please enter a list of Known Mappings under KnownMaps.txt"; Return} $computerlist = Get-Content C:\Scripts\Workstations.txt # Loop through each item in the array (each computer in the list of computers we loaded into the variable) ForEach ($computer in $computerlist) { $diskObject = Get-WmiObject Win32_MappedLogicalDisk -computerName $computer | Select Name,ProviderName | Out-File C:\Tester\Computers\$computer.txt -width 200 } Select-String -Path C:\Tester\Computers\*.txt -Pattern cmsfiles | Out-File C:\Tester\Drivemaps-all.txt $strings = Get-Content C:\Tester\KnownMaps.txt Select-String -Path C:\Tester\Drivemaps-all.txt -Pattern $strings -notmatch -simplematch | Out-File C:\Tester\Drivemaps-nonmatch.txt -Width 200 Select-String -Path C:\Tester\Drivemaps-all.txt -Pattern $strings -simplematch | Out-File C:\Tester\Drivemaps-match.txt -Width 200

• different user group can not upload file in the server

  - by Dallal

  I have a CentOS server running in Thailand, and I'm in Canada. The guy at the computer center who set up the server for me doesn't really understand much about linux and left me off an issue to solve myself. I just moved from Mac Server to Linux server, and the first thing I'm facing a problem now is `file name` has failed to upload due to an error The uploaded file could not be moved to `location name` So what happen is that I knew from my experiences of these problem is all about permissions. So I go ahead and checked on my whole folder and found that everything in the folder permission is like myusername mygroupname then I checked the httpd file in the server and it is default to apache apache. My question is that how can I make my user to be in the same group with apache group so that I don't have to have any problem about uploading, changing data in my file....? But without having to affect other user in the same server. I'm holding Administrator account, but not root account, but I can change stuff on the server root no problem. When I was with godaddy.com there never been any problem about the permission and I wish I know how they configure that :(

• Permissions for Multiple User VPS

  - by adnymarc

  I have a Linode VPS server that I have recently setup and am migrating to from Mediatemple, where I have a VPS managed by Plesk. I dislike the Plesk interface and the mess it makes of a lot of things, but appreciated its ability to allow multiple people access to different domains on a server. I have most everything setup the way I would like it, but am having issues with permissions for my domain directories. I am running Ubuntu 8.04 LTS and Apache 2 as my web server. I have domains successfully located in /var/www/vhosts/domainname.com but have to modify files as root in order to add/change files for the domains. I would like to setup access with the following criteria: Each domain can have a user assigned to it (and allow for the same user to manage multiple domains - could even create symlinks in their home folder to their domains) Certain users will have shell access and may be chrooted to the domain directory they control FTP needs to be setup and able to correctly access the domains so that content editors for each domain can upload/download without permissions issues I am relatively new to linux sysadmin and have searched for a good guide to help solve these issues but haven't been able to find one yet. Thanks in advance for your help.

• Microsoft WPF Certification

  - by Carlo

  I'm seriously thinking about getting this certification. I already contacted Apex InfoTech and they gave me prices and everything. This is the description of the course. It lasts for 3 days, and the price is $1,495. What do you guys think, is it worth it? I've already been using WPF for a a bit more than a year, but I think a little Microsoft Certification badge would be good for my business card and resume. Let me know what you think. Thanks!

• Silverlight MVVM conversion from WPF

  - by IrishJoker

  I was reading this article - http://msdn.microsoft.com/en-us/magazine/dd419663.aspx And I came across this piece of code in the WPF Demo application that came with the article. This template applies a CustomerView to an instance of the CustomerViewModel class shown in the main window. <DataTemplate DataType="{x:Type vm:CustomerViewModel}"> <vw:CustomerView /> </DataTemplate> I substituted the angle brackets for square brackets - not sure how to post them. The code is in the MainWindowResourses.xaml and the code starts on line 19. Anyone know how I can do this in Silverlight ?? We don't have the DataType and I need to be able to tell the app that this View is associated with this ViewModel - so I can create a tab control with different view like the demo app. Cheers, EC

• Get XAML from WPF Custom RichTextFormat

  - by Erika

  I've looked at other posts, but i cant seem to find something that works. I have a custom control WPF RichTextBox and would like to obtain the XAML from this control. I have tried the following //rt is the name of this particular custom richtextbox TextRange range = new TextRange(rt.Document.ContentStart, rt.Document.ContentEnd); MemoryStream stream = new MemoryStream(); range.Save(stream, DataFormats.Xaml); string xamlText = Encoding.UTF8.GetString(stream.ToArray()); return xamlText; but this doesnt seem to work :s I can access the rt.Document.Content start etc but it seems to crash there "Object Reference not set to instance of an object". I am using the richtextbox directly from the .xaml.cs so it should be initiated and so on :s. Any Ideas or other ways to get the XAML from a richtextbox pls? (i'm requiring the XAML cos i actually want to get the HTML.. if theres some other direct manner perhaps?)

• Creating an installer with WPF forms, packaged files and custom setup actions

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• wpf c# media player questions

  - by Sankar

  I'm making a media player in wpf using c#. I had 3 questions. 1) I tried making a seeker XAML: <Slider Name="timelineSlider" Margin="40,91,26,0" ValueChanged="SeekToMediaPosition" Height="32" VerticalAlignment="Top" /> Code: private void Element_MediaOpened(object sender, EventArgs e) { timelineSlider.Maximum = ply.NaturalDuration.TimeSpan.TotalMilliseconds; } private void SeekToMediaPosition(object sender, RoutedPropertyChangedEventArgs<double> e) { int SliderValue = (int)timelineSlider.Value; TimeSpan ts = new TimeSpan(SliderValue, SliderValue, SliderValue, SliderValue, SliderValue); ply.Position = ts; } When I run the program, I open the mp3 and play it but the seeker won't move. When I click on the seeker to move it to a certain position, the song stops playing but the seeker moves. What's the problem and how do I fix it? How do I create a volume increase/decrease bar? How can I open several mp3s and queue them up like a playlist? Thank you

• Binding list of objects to WPF ListView

  - by Dave Colwell

  Hi all, I have a list of objects which i want to bind to a ListView control in my WPF application. The Objects have a DataTemplate already, so no need to define that. The list of objects is a property in the codebehind file in the format list<object> When i add one object programatically, it appears fine. But when i try to bind the ItemSource of the ListBox to the list of objects, nothing shows up. I am using the following binding: ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Portfolios}" where the name of the property i am trying to bind to is Portfolios and exists on the parent window

• Real winforms/wpf projects which use MVC, MVP, MVVM

  - by Belousov Pavel

  Hello everybody, I have looked some videos and read some articles about MVC, MVP, MVVM. I think, that I understood basic principles and differences. But it seems to me that samples in articles and videos are very easy. I think that it's easy to learn how to apply these patterns when you can look on some projects. So I'd like to look on real projects(Winforms/WPF), which use MVC, MVP or MVVM. Could you provide me links to sources of such projects? (If it is open source) It will be great if projects will have unit tests for Controller/Presenter/ViewModel, because it's one of my problem when I develop applications. Thanks in advance.

• Uri for bitmap in subfolder (c# wpf)

  - by the empirical programmer

  I have a wpf app where I'm using an image. To reference the image I use: Uri uri = new Uri("pack://application:,,,/assemblyName;Component/myIcon.png"); BitmapImage(uri) If I add the png directly under the csproj file (with its properties BuildAction=Resource) then it works fine. But I want to move it to a subfolder under the csproj. Another SO question asked about bitmaps\uri's (857732) and an answer linked to this msdn. So I tried : Uri uri = new Uri("pack://application:,,,/assemblyName;Component/Icons/myIcon.png"); But that did not work. Any ideas?

• WPF Composite - Expose EF model to all modules

  Hi All, I have an application that uses WPF Composite, and I have an issue. I've got a big database that is attached to the application and I need it exposed to different modules as part of the application. What is the best way to expose my Entity Framework model to all my different modules and views inside them? Do I have one EF model or a separate one for each module and then only the tables that each module needs. The only problem being that some tables have a relationship and will have different views and those views will be in different modules. Any ideas how to resolve this?

• VS 2008 - Procedure to ship C#/WPF solution to ensure compatibility

  I am attempting to collaborate on a C#/WPF project with another developer remotely via e-mail; and although the code compiles perfectly when it leaves, my collaborator has not been able to compile the code on his side. We are both using VS 2008 Version 9. This is the first time trying to work with someone else on an application and I was hoping that someone would advise me if there are any suggestions to obtain and ensure compatibility between the two of us? Additionally, is there a recommended procedure to prepare the solution for shipment (ie. just zip up the solution folder? export the application? etc.)? Thanks very much.

• Backup Permissions for an Active Directory Profile Directory

  I have Folder Redirection turned on so the profiles are on a Windows shared folder on a File and Print Server... \folders\Profiles I want to back up the entire Profiles directory, but as Domain Admin I don't seem to have the privileges to "select all and copy" the entire directory structure. The user profile subfolders (Appdata, Documents, Desktop, Pictures, etc.) throw access denied errors... I tried to grant Domain Admins full privileges to the Profiles directory and thought the subfolders would inherit the privileges, but I get access denied errors just trying to set the permissions... How can I assign a user to the Profiles directory so that I can copy the entire directory tree to back it up?
