Re: X Forwarding via SSH

not sure, but, think you missed my out-of-order ssh commandline
inserted back in before your comments below
connections between foo and westek is assumed to be over ssh

lots of things can be done to run securely or
other "conveniences" .... good or bad is up to them...

- X11 should not be running if security is an issue...
- if one insists on running X11, one should never login as root in xdm...
- ssh/X11 forwarding is assumed to be on still...
