Whilst you can see the "--resumesession" or the "tail . . .
/session", then there's no point in trying any more reconnections
Instead, run "cat /share/homeuser1/.nx/C- etc etc /session" file to
see how far it got.
If you look in the session file after a disconnect, don't worry about the
garbage at its beginning.
It's caused by clearing the file with an echo > but then tee keeps writing
where it left off . . .
In the session file you should see all or part of something like :-
Session: Resuming session at 'Wed May 23 11:17:00 2012'.
Info: Proxy running in server mode with pid '25121'.
Info: Waiting for connection from '127.0.0.1' on port '5012'.
Info: Accepted connection from '127.0.0.1'.
Info: Connection with remote proxy completed.
By 11:18 there ought to have been a child nxagent spawned by 25121 and/or
a "netcat 127.0.0.1 5012" . . .
