Thanks much Chris. That's exactly what I needed. I remain convinced
that most users probably want this functionality turned off.
After messing with this last night for a couple hours I never found
the problem. As far as I can tell my hosts.equiv, dns names, users,
etc. are all set up properly. Even compared against 2 working
clusters (both running torque 2.4.2).
In the end my solution was to try the exact same install procedure
with each version of torque successively going backward. My procedure
is the stupid-simple install:
When I got back to 2.4.2 it magically worked. I do not know what is
broken with each successive version since then, but the above worked
with 2.4.2 and not with any version since. I will be happy to isolate
this and file a proper bug report if someone will work with me on it.
