I don't know much about how our RPMs configure Condor, but I can see that 
something is wrong here...  Your central manager (node1) should be running 
both the collector and the negotiator.  Look at the DAEMON_LIST setting in 
the condor_config (or condor_config.local), and make sure that both COLLECTOR 
NEGOTIATOR is in the list.

Also, if you don't want to be running jobs on this machine, remove STARTD from 
the list.  Similarly, if you aren't going to be submitting jobs from this 
host, remove SCHEDD from the list.

Again, edit your condor_config on the execution node(s), and remove COLLECTOR 
and NEGOTIATOR from the DAEMON_LIST.

As above, I'll note that you're running the schedd here, which allows you to 
submit jobs from this host.  If this is not what you intended, then remove 
SCHEDD from the list.

You'll need to restart Condor on the affected nodes for these changes to take 
effect.  "condor_restart -master node1", or "/etc/init.d/condor restart" (or 
similar).

Nope.  See above.  I don't know _why_ they're set as they are, but it's 
obviously wrong.

Try the above first -- it'll probably solve the problems that you're seeing.  
If not, we can pursue it further.

Glad to help!
