UNIX for Dummies Questions & Answers

Hello sir.
I used to invoke the remote terminal in any 2 RED HAT 9 systems using the command :-
But when I tried this on a FEDORA 8 or FEDORA 10 system.....it says that "cannot display".......Can you please tell me why is fedora distro not allowing me to do so? I need to invoke the remote terminal. I dont know anything other than "ssh".Can you please tell me the command if we can use some other command to do so ?

If al you need is a terminal session, then just

Code:

ssh root@<ip address>

is all that you need, but if you want to run some gui apps then you will need X forwarding. Ensure that

Code:

AllowX11Forwarding              yes

is set correctly in your ssh servers config file (/etc/ssh/sshd_config)
and that

Code:

ForwardX11                      yes

is set in the clients config file (/etc/ssh/ssh_config)
also have a look at the man page for ssh particularly the -X and -Y options.
