In this regard, I've noticed that on *some* of our computer X forwarding
occurs automatically when using ssh2, but on others it does not. Since all
machines were set up identically, it is very confusing and irritating.
I've noticed that, if I slogin to machine "A_host" and check the setting
of DISPLAY with the "env" command, it will say: "DISPLAY=A_host:11.0
That seems to properly X-forward.
However, on those machines which do not X-forward (all of the others!),
when I slogin into any of our other machines, e.g., "B_host",
then DISPLAY=:0
On these machines I seem to have no choice but to use setenv
DISPLAY=<hostname>:0.0
Does anyone have a suggested explanation?
Have I missed something?
