Accessing Git Repositories using SSH behind HTTP proxy (TortoiseGit, Putty)

There's an easier way to do this since my previous post on the subject above. SSH key generation steps are not discussed here, but the only thing worth mentioning here is that the private key be in PPK format (use PuTTYgen to convert them)

Using TortoiseGit, use Putty to save a 'Session'. Name the session short and simple e.g. hornetsnest. This is significant and to make things simpler, no spaces for the session names.

Under the saved Putty session, the place to add proxy information is at Connection > Proxy. For HTTP proxy:
  • Proxy hostname - IP or host name of proxy server
  • Port - Proxy server port e.g. 8080
  • Username - User login Id if proxy server requires authentication
  • Password - Login Id password
To associate a SSH key, go to SSH > Auth and specify the PPK key file path under "Private key for authentication".

Remember to save the Putty session.

Now, shift over to TortoiseGit. In the window to specify the Git repository URL, instead of the usual host name value, replace it with the Putty session name. In this example, hornetsnest. So

ssh://workerbee@imperialpalace.ip/~/git/super.git

becomes

ssh://workerbee@hornetsnest/~/git/super.git

So the connection to the Git repository via SSH will use the settings in the Putty's session. Of course, when you are not behind a proxy, you can just revert to the original URL when cloning/pulling/pushing.

Minor update: You'll need to use TortoisePlink as SSH client:
