pushing to github from work "Bad file number" error

I got msysgit installed at my computer. And I configured it to work with github at home, where everything went fine. At work it do开发者_开发技巧esn't:

D:\rails_tutorial_projects\first_app>git push --verbose
Pushing to git@github.com:Monomachus/DemoRubyApp.git
ssh: connect to host github.com port 22: Bad file number
fatal: The remote end hung up unexpectedly

I read about Smart HTTP Support https://github.com/blog/642-smart-http-support

But it seems that it doesn't work too. I make clone and all that stuff without problems but when I try to push changes back to github this is where the same problems came in.

My msysgit version is git version 1.7.3.1.msysgit.0

Please help me with this awkward situation.

This error is also caused by attempting to push/clone etc. through a proxy server. Since you mentioned you are at a business, do they use a proxy server there?

The error is git literally saying, "hey, the file isn't there", because it can't get through the proxy server.
