A simple way to access GitHub repositories inside the University of Nantes
$ ssh -f -N -L:9418:github.com:9418 <e+n°etu>@bastion.etu.univ-nantes.fr
$ git clone git://localhost/ojbruce/BDD_project.git
$ git push -v https://github.com/ojbruce/BDD_project.git
This command also works without bastion (just for pushing), but be carefull to correctly setup the proxy (git config http.proxy)
$ git pull -v git://localhost/ojbruce/BDD_project.git
You have to kill the SSH process
$kill -9 <processus SSH>
Enjoy !
