I am behind a proxy in my college and things like ftp and ssh don't really work out of the box. I just set up git on my laptop and I configured it's proxy and I am able to push and fetch via http(s) methods.
However I want to be able to connect via ssh to my github repo. I spent a couple of hours reading workarounds online and trying to ssh into my github repo using corkscrew to tunnel the http proxy.
My ~/.ssh/config file looks something like this:
Host github.com
Hostname ssh.github.com
Port 443
ProxyCommand corkscrew proxy62.iitd.ernet.in 80 %h %p ~/.corkscrew-auth
Debugging the ssh attempt yields the following messages:
OpenSSH_5.9p1 Debian-5ubuntu1.1, OpenSSL 1.0.1 14 Mar 2012

Proxy could not open connnection to ssh.github.com: Method Not Allowed
ssh_exchange_identification: Connection closed by remote host
Since the proxy server here requires authentication, I created a corkscrew.auth file in my home directory where I put in my credentials in the form username:password.
How do I correctly set up ssh here? I think I should be able to ssh using http-proxy tunneling no matter what. I would appreciate any help.
You should replace proxy62.iitd.ernet.in 80 with 10.10.78.62 3128. In addition, you could remove the ~/.corkscew-auth and simply stay logged into the proxy from the browser
