I've done this without troubles on Redhat, using the basic following procedure: on host side, enter: xhost +client_sys_name on client side, enter: export DISPLAY="host_sys_name:0.0" then run the app. I've been unable to get this to run at all on SUSE 9.1 with the latest kernel update(linux-2.6.5-7.95) as the host machine and a Redhat 7.3 machine as client. That same Redhat machine works fine with other Redhat machines. The results I get are typically: Error: Can't open display: host_sys_name:0.0 I've run through the Yast security settings - the only thing that seems vaguely related is "Allow Graphical Login", although I doubt that's involved I ticked it and restarted X. Still no go. I'm not running a firewall, I unfortunately need to run an app as root but I can't even get xeyes to run as myself, so small steps first. I'm suspecting it's a security issue, as opposed to any sort of incompatibility. Any thoughts or suggestions? I need it to work this way(not looking for vnc solutions), and it should, shouldn't it?

IIRC for this to work you will have to open ports 6000-6063 on your host firewall. This may have possible security implications. It would be better to use ssh with the -X option. Cheers, Alex.

Lol! I've *really* got to start doing more reading about ssh. :P It worked a charm, thanks a lot!

Indeed. X in SuSE 9.1 by default does not accept TCP network connections. If you are doing this over the internet, consider using "ssh -X" instead If you are doing this on a secure LAN and you *really* want to do it unencrypted, then edit /etc/sysconfig/displaymanager and set DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN to "yes" and run SuSEconfig and restart X

I believe Putty will do that: http://www.chiark.greenend.org.uk/~sgtatham/putty/ Cheers, Alex.

indeed and putty is excellent
I have PuTTY already-- I also have my "host" laptop set up where I can SSH in to a text terminal, but can't get an X session going... What am I missing?

not sure if I understand you correctly and really I'm no expert but do you mean the settings in connection/ssh/tunnels? in putty obviously 8)

putty has a built-in X server now?

Look at x.cygwin.com, Xfree under Microsoft Windows. Greg Engel PS Have not tried it, just saw it.

You're going to need to install an X server for windows, perhaps the one in cygwin? After that, I think the ssh client in cygwin will do it for you
