Sometimes life doesn’t work out, you want to be able to push/pull your code to github but the machine you are working on doesn’t have internet access to do so and in my case the receiving github server is internal so even with internet it would not have worked.
How to fix this with a reverse tunnel, add the following to your local ~/.ssh/config
Host example-host RemoteForward 12222 github.com:22
And on example-host, add this to the ~/.ssh/config
Host github.com hostname localhost port 12222
Now, I’m assuming you already have a straight line to the host you are working on, if not using ProxyCommand might solve that. And that you have AgentForwarding enabled because unprotected ssh keys are bad m’kay.
Now, once this is setup, you ssh to the host and should be able to use it without voodoo on the prompt
git clone email@example.com:username/project
