I'm setting up another cluster, this time with condor 6.8.2.  I tried 
setting 'NETWORK_INTERFACE=10.255.255.*' in condor_config, and condor 
did bind to the correct interface.  But it did not seem to find the 
correct local IP address for the machine on that network:

12/4 16:21:00 attempt to connect to <10.255.255.255:33270> failed: 
Network is unreachable (connect errno = 101).  Will keep trying for 20 
total seconds (20 to go).

If I set 'NETWORK_INTERFACE=10.*.*.*', then it ignores the setting and 
listens on the public interface.  Is there a different way that I'm 
supposed to specify the local interface/IP without setting 
NETWORK_INTERFACE=<local-ip> in every host's condor_config.local?
