Answer by Daniel Krenn for I have access to a remote server through a gate computer with this command:ssh -fN -l user -L port:host:22 gate #To Bring up the tunnelssh -X -p port user@localhost #To open an X session to my serverOnce on the server I run sage by typing "./sage" in the installation directory. Now the questions:1)Which are the right commands to bring up the remote notebook server?2)What should I type in my local browser? (I suppose something like 'localhost:port', but even without launching the notebook server I get the following error:'SSH-2.0-OpenSSH_4.3 Protocol mismatch')I tried to read the instructions and the wiki, but I confess that I am at a loss.Thanks a lotGiovanni

1. Connect via ssh to your server and bind port, e.g. ssh -L 8000:localhost:8000 user@your.server.com You can use some extra ssh-options if you want... 2. Run ./sage -notebook on your server. 3. Open a browser (locally) and type in http://localhost:8000 BTW: You do not need a X session to your server for that.
