X11 forwarding using SSH

First of all open MAC terminal and try:
MAC#ssh -X -l login-name hostname/ip-add

This command will enable X login in the remote system. If you are logged in the remote system, you can run graphical tool in the remote system. For example, say we logged in the RHEL system,

RHEL#system-config-network-gui will run the graphical network config tool over the network.

RHEL#xclock will run the graphical clock of the system remotely.
