Good day to you all...
I am able to do the following successfully:
ssh -X 10.1.1.47 (once connected...) /usr/openv/netbackup/bin/jnbSA &
The above works just fine...
However, if I try the following:
ssh -X 10.1.1.47 /usr/openv/netbackup/bin/jnbSA
it doesn't work. :(
But... if I do this:
ssh -X 10.1.1.47 xeyes
It works just peachy...
I'll be honest, I have no idea but as a suggestion, given you are wise and are using a proper operating system, strace / truss it, and compare against the 'xeyes' command and see if that givens any clues.
