This is exactly what I was looking for - thank you very much!

I had been looking at the xauth command, but being somewhat new to X, the man page
was not exactly making thinks clear. (I've been using it blindly for a few years but never needed
to understand much of what it did.)

Can you point me to any good source of understanding, or a reference for newbies? I'm sure
people are going to be asking me how all this works and what the various parts do.

Again, thanks!

Steve
