X11 over SSH
CentOS 5's and Fedora 15's base installations are pretty good prepared to use X11 over SSH. You just need to install one more package on the server you're connecting to: xorg-x11-xauth. According to yum info, the purpose of this package is:
xauth is used to edit and display the authorization information used in connecting to an X server.
This editting probably means synchronising X11 authority cookies between SSH peers.
Installing is done using:
yum install xorg-x11-xauth
Then ssh into the box using:
ssh -X [servername]© GeekLabInfo
