Okay thanks!

But...how do I use xauth?  I have tried doing what what suggested in the man
page ie variants of

xauth extract - $DISPLAY | rsh otherhost xauth merge -

but there still seems to be a problem.  One thing I was wondering is if this
works when dhcpd is used.  In particular, the machine in my DISPLAY variable on
the remote machine is different from the machine in the .Xauthority file (on the

remote machine)

Is there a way to deal with this do you know?
