problem getting repository

am using proxy server to get clone on linux. When i type command of git clone

" git clone git:// libo "

i get following errror:[0:]: errno=Connection refused fatal: unable to connect a
socket (Connection refused)

Unable to understand. I even ping. And set http.proxy with my proxy and port address.


I am behind a HTTP proxy, I even try

and get this new error:

Cloning into core... error: The requested URL returned error: 403

while accessing

fatal: HTTP request failed

Please, Help!
