I wonder if Novell knows what networking is. :-) There are a couple of things to check and/or consider when doing X- forwarding over SSH: - check the local $DISPLAY (before you ssh into the server), which should be set to something like ":0" - authorize localhost to access the local X server with "xhost +localhost" (xhost without any options displays the current ACL) - try ssh with the "-Y" switch instead of "-X" (if you're not using it already). - use ssh with at least one "-v" switch. This may give you very useful hints to what's going wrong. It could be something like /usr/X11R6/bin/xauth that's missing on the remote server (multiple -v switches increase verbosity even more) - check the remote $DISPLAY after you login, which should be something like "localhost:10.0" - if the remote $DISPLAY does not get set when using ssh -Y, check the sshd_config on the server. There should be a line that reads "X11Forwarding yes" And, if you didn't know this already, the SuSE distro contains the "/ usr/X11R6/bin/sux" script, which provides a convenient alternative to su (actually just a wrapper). This preserves your X environment variables. Good luck :-) Leander ------------------------------------------------------------------------- Using Tomcat but need to do more?
