"Unable to open ToolTalk channel"
If you open an X window on a remote system and want to run
an Xwindows app from there and see the display back on your
desktop, the first thing you
normally do is play with 'xhost' on your desktop and the
value of the $DISPLAY variable in the remote X window:
The 'xhost' command is run on your local desktop, and the
DISPLAY setting is done in the X window on the remote system.
DISPLAY=mydesk:0.0; export DISPLAY
If the app is a little smarter than the average bear, you
may get this error when you try to start it up:
Unable to open ToolTalk channel
Here's how to work around the error:
In this example, machine would be your desktop
(not the remote machine you're executing the ttsession
command on) and command is the X application
you're trying to run on the remote system.
/usr/dt/bin/ttsession -s -d machine:0.0 -c command
