Thanks for the information.  Unfortunately this doesn't seem to work for 
me although the network policy isn't anywhere as draconian as yours 
was/is.  I tried cloning using different approaches but none seems to 
work, maybe I'm doing something wrong:

  1. I setup my .ssh/config suitably based on the above (and 
experimented with various options)

Host github.com
         User git
         HostName github.com # also tried ssh.github.com
         Port 443
         ProxyCommand /usr/bin/corkscrew my_proxy.iitb.ac.in  80 %h %p 
         IdentityFile /home/prabhu/.ssh/id_dsa.pub

  2. $ git clone --origin svn git://github.com/pv/scipy-svn.git scipy.git

And it does not work at all.  I get this:

Initialized empty Git repository in /.../scipy.git/.git/

and nothing for a long while and eventually something like this:

github.com[0:]: errno=Connection timed out
fatal: unable to connect a socket (Connection timed out)
fetch-pack from 'git://github.com/pv/scipy-svn.git' failed.

svn has worked well for me in this regard.  I have always been able to 
checkin and checkout stuff with svn.

Finally, this worked:
proxycmd git clone --origin svn http://github.com/pv/scipy-svn.git scipy.git

proxycmd is just a simple shell script that prompts for my password and 
sets up the http_proxy for the subsequent command.
