By default, the ssh connection to your Red Hat should forward X connections securely over the ssh link. You may be circumventing this security by setting the DISPLAY variable yourself. Check the DISPLAY variable after you use ssh to login: set | grep DISPLAY or: echo $DISPLAY and see what that says...it should be something like: localhost:10.0 or: 127.0.0.1:10.0 If that is correct, try to start something: xterm & and see if it displays on the Mac box.

Help is much appretiated. You should be able to do the following: 1) ssh into your redhat box from your OSX box. 2) Assumming that you use the bash shell, type export DISPLAY=192.168.0.1:0.0, replacing the IP address with the IP address of your OSX box. 3) At this point, if your OSX box is configured correctly and ready to accept X11 connections, you should be able to start an x program and it will send the X11 packets over to the host specified in your DISPLAY variable. -Erik _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
