Hello John,

By default bosserver will listen on all the interfaces. The bosserver
only uses the NetInfo/NetRestrict files when it is started with the
-rxbind option.

You can verify the interfaces it is listening on with a netstat -a -u.
I like to use the options, -a, -u, -n, and -p (the -p options requires
you to be running as root). You should see bosserver listening on
if it is listening on any interface;

$ sudo netstat -aunp | grep 7007
udp  0   0*      31246/bosserver

Unfortunately, this log message is misleading, and is my error. It does not
mean bosserver is listening exclusively on the loopback interface.  The
loopback address is logged when the bosserver is also listening on all
addresses.  This log entry was added when we added the new bosserver.rxbind
file to give init scripts a way to shutdown the bosserver when it is started
with the -rxbind option.  I've submitted a fix to gerrit to fix the misleading
BosLog message.
