D.2.1 OpenSSH

In most cases, SSH will forward X11 traffic by default, so the simplest thing is to go ahead and try it. To explicitly enable X11 forwarding use the -X option to ssh. If you want to disable it for some reason (for instance, it is too slow for your taste and you have a tendency to inadvertently start up graphical tools instead of commandline ones), then use the -x option.
