I have searched around and have nowhere else to turn. I wonder if anyone
else here has ran into this problem?
I have turned on X11 forwarding. I have no problem with running a command
to open an xterm window or another X app on a node
eg:
[kaizaad@beowulf kaizaad]$ ssh node2 /xtest
opens an test xterm window from node2. The display enviornment variable
is already set by ssh and the window pops up on my screen.
The problem arises is I use pvm to spawn a window on a node.
eg:
pvm> conf
conf
2 hosts, 1 data format
HOST DTID ARCH SPEED DSIG
beowulf 40000 LINUX 1000 0x00408841
node2.brockwulf.ca 80000 LINUX 1000 0x00408841
pvm> spawn -node2.brockwulf.ca /xtest
spawn -node2.brockwulf.ca /xtest
1 successful
t80001
Looks good but no window pops up and when I check the log
file /tmp/pvml.1745 I get
[t80040000] 01/21 15:32:21 [t80001] /xtest Xt error: Can't open display:
node2.brockwulf.ca:10.0
The test_cluster script (supplied with OSCAR) works fine so I think my PVM
works. And I haven't got any complaints from people using pvm if they
don't have any X windows that they need to popup.
Has anyone else run into this problem? I could turn X11 forwarding off
but I would rather keep it encrypted.
thanks a bunch
