Or try this:
#!/bin/bash
if [ "$1" == "" -o "$1" == "fromremote" ] ; then
# same machine
su -c "cd ; xauth add `xauth list $DISPLAY`; xterm -ls -vb -sb -sl
2000 -T Root@`hostname -f` -n Root@`hostname -f` -j -rw +vb -bg \#ff8c6d
-fn 10x20 &"
# sleep to give the xterm time to open
[ "$1" == "fromremote" ] && sleep 1
else
cmd="\"export DISPLAY=$DISPLAY;xauth add `xauth list
$DISPLAY`;xterm -geometry 20x1 +sb -e xsu fromremote\""
rsh $1 "bash -c $cmd"
fi
Works very nice over rlogin, too. It add's the users xauth entry to roots
XAuthority instead of letting root manipulate the users .XAuthority
Have Fun,
Schlomo
PS: I couldn't resist sending it because it's the product of a quite long
improvement curve and I still have some open issues: Like skipping the
cmd= stuff for the rsh. Without it it always would loose the quotes ...
