Setting up a Git server on Windows using Git for Windows and Win32_OpenSSH

You need to download and install:

• Install Win32_OpenSSH
• Git for Windows, selecting the "Run Git and included Unix tools from the Windows Command Prompt" when prompted. This option will install a bin folder in Program Files\git that will be placed into your path thus taking possibly taking precedence over other tools.

On Server

1. Set system environment variable for sshd to pick up the git commands

   $gitPath = Join-Path -Path $env:ProgramFiles -ChildPath "git\mingw64\bin"
   $machinePath = [Environment]::GetEnvironmentVariable('Path', 'MACHINE')
   [Environment]::SetEnvironmentVariable('Path', "$gitPath;$machinePath", 'Machine')

2. Restart sshd so the changes to the Path environment variable can take effect.
3. Create Windows users for all Git users.
4. Create a central Git repositories
   • Go to where you want to create a central repo, git clone --bare <source dir> A directory with name <source dir>.git will be created. In it will be the .git contents of your source dir repo. for example

   git clone --bare c:\git\newrepo.git
   

5. If you already have user private and public keys, copy the public key to C:\Users{user}.ssh\ and rename it to authorized_keys

On Client

1. Set environment variable for git to use Win32_OpenSSH

   $env:GIT_SSH_COMMAND = '"C:\Program Files\OpenSSH\ssh.exe" -T'

2. (Optional) Register the user private key for single sign on

   ssh-add.exe <user priviate>

3. To check out a repository: **Note that git clone username@domain@servermachine:C:/test/myrepo.git does not work due to known issue. Work around it by following steps:

   # initialize a local repo folder
   git init mylocalrepo
   cd mylocalrepo
   # add the remote repro
   git remote add origin username@domain@servermachine:C:/test/myrepo.git
   # work around the known issue by launching powershell to run the git commands
   git config --local remote.origin.uploadpack "powershell git-upload-pack"
   git config --local remote.origin.receivepack "powershell git-receive-pack"
   git fetch origin
