Here is how to configure X11 forwarding with ssh.
Takes under a minute to configure:
1. On the SERVER: set “X11Forwarding yes” in your
/etc/ssh/sshd_config |
2. On the SERVER in the USER’s home dir:
sudo rm -f .Xauth* |
3. On the client:
ssh -2 -4 -C -X -v USER@SERVER |
4. Once logged in to the SERVER run “xclock” to confirm
done 
I am trying to do what is suggested, however on my school box “sshd_config” is protected. Any thoughts?
unprotect it
do: sudo vi sshd_config
or find someone who has permissions to do so
Thank you – very precise and short.
Tool me under 3 minutes – am I slow?
But it does really what it supposed to, that is cool!
You can also use the following command
ssh hostname -X
the X switch tells ssh to forward X11 info for that session. It can be done without changing the sshd_config file.
