I followed the steps described in http://returnbooleantrue.blogspot.com/2009/06/using-github-through-draconian-proxies.html, but then connecting to the internal server fails:
Proxy could not open connnection to 192.168.1.***: Forbidden ssh_exchange_identification: Connection closed by remote host svn: Commit failed (details follow): svn: Network connection closed unexpectedly
Can I set up
config file so that
ProxyCommand is only used for ssh.github.com?
