Right, this will run on the existing (if any) X display on 'bar', if you have permissions to do so, it exists, etc. > Trying "export DISPLAY=my_ip_address:0.0" returns something like > "Xlib: client is not authorized to connect to server" which seems to > indicate that something is missing or lacking on the local machine. > Any suggestions where to look? First: you're not doing this right. You want to ssh to the remote host with X11 forwarding set. This both sets all your DISPLAY environment settings properly *AND* tunnels the session through an encrypted SSH session back to your local (foo) display. On the client side (foo): ssh -X bar <connection established> <run X command> You can shortcut this to: ssh -Xf bar <command> ...which will set up the SSH session, the X11 tunnel, run your command, then fork SSH to background until your X application closes. On the server side, it's necessary to enable X11 forwarding. Generally in /etc/ssh/sshd_conf . Many distros disable this by default (it's an access/security issue, though in the grand scheme of things, a lesser risk than many sins). You'll also find: - Mark Kim's "xhost+" advice. DON'T DO THIS. EVER. Google for the reasons, they're well known and tedious to recount. Fortunately, most sane X servers don't allow this in their default sessions. - Most X servers don't allow remote TCP connections. These may also be blocked at other stages, including IP filters and (possibly) tcpwrappers (not sure on last). - You don't have a cookie. It's magic. It's from a secret recipie sold by MIT for $50,000. Wait, wrong chain mail.... Peace. -- Karsten M.
