Possible this is the problem with this machine: no other machine in my
pool is using DHCP except for this VM. I did a forward and reverse
lookup on the negotiator machine and after I did that the machine showed
up. I'm guessing it forced a DNS update on the box.

That's a resonabe explanation but the rejected message doesn't seem very
explicit in this case:

6/29 12:36:19 DaemonCore: PERMISSION DENIED to unknown user from host
<137.57.174.68:45472> for command 2 (UPDATE_MASTER_AD), access level
ADVERTISE_MASTER
6/29 12:36:19 Got QUERY_STARTD_ADS
6/29 12:36:19 (Sending 758 ads in response to query)
6/29 12:36:23 DaemonCore: PERMISSION DENIED to unknown user from host
<137.57.174.68:59677> for command 0 (UPDATE_STARTD_AD), access level
ADVERTISE_STARTD
6/29 12:36:24 Got QUERY_SUBMITTOR_ADS
6/29 12:36:24 (Sending 10 ads in response to query)
6/29 12:36:24 DaemonCore: PERMISSION DENIED to unknown user from host
<137.57.174.68:49270> for command 0 (UPDATE_STARTD_AD), access level
ADVERTISE_STARTD

Can someone from the Condor team confirm or deny that this is the
rejected message I'd see if my hostname <--> IP for an executor didn't
match up at the negotiator?
