There are several ways to see if a machine is set to execute jobs in your
Condor pool:

* Run condor_status and see if the hostname appears in the output. If the
hostname doesn't appear, then Condor isn't aware of it as an execute node.

* On the machine, run ps and look for any process named condor_startd.
condor_startd is the daemon that makes a machine an execute node.

* On the machine, run condor_config_val -master DAEMON_LIST and see if
"STARTD" appears in the results. This will tell you if Condor is
configured to run the condor_startd daemon. You can also look in the
config file (which is where you'd change DAEMON_LIST if STARTD is listed).

* On the machine, look for a file StartLog in the Condor log directory. If
it's present and has recent entries in it, the condor_startd is probably
running.

As for what interface the Condor daemons are using, every Condor daemon
writes something like the following to its log when it starts:

12/31 16:58:38 ******************************************************
12/31 16:58:38 ** condor_master (CONDOR_MASTER) STARTING UP
12/31 16:58:38 ** $CondorVersion: 6.6.1 Dec 30 2003 RH9-BRANCH-PRE-RELEASE $
12/31 16:58:38 ** $CondorPlatform: I386-LINUX-RH9 $
12/31 16:58:38 ** PID = 7125
12/31 16:58:38 ******************************************************
12/31 16:58:38 Using config file: /some/path/name

12/31 16:58:38 DaemonCore: Command Socket at <128.105.111.110:32873>

That last line tells you the ip:port the daemon is listening on. All
outgoing connections will be made on the same network interface. If it
reads 127.0.0.1, you're going to have problems. :-)
