Hi Tom,

NETWORK_INTERFACE is one of the (rare) config settings that cannot be 
changed on the fly... you need to shutdown HTCondor, change 
NETWORK_INTERFACE, and then restart up HTCondor again.

Also note that setting NETWORK_INTERFACE=127.0.0.1 means that you truly 
have a condor pool of one node - no HTCondor tools or daemons will 
communicate over the network.
