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 doesn’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

Please help me with this awkward situation.

  • git-cat-file output
  • msysgit: Unicode font warning
  • Git can't find .ssh
  • Cannot clone git repository with new user
  • Git launches mergetool without any arguments
  • Problems cloning a git repository (Newbie problems)
  • Should Git ever think a file that it got from a pull is now untracked?
  • Restore read-only status when switching branches in msysgit
  • One Solution collect form web for “pushing to github from work “Bad file number” error”

    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.

    Git Baby is a git and github fan, let's start git clone.
