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.
