It is the networking copyright daemon, /etc/cpd.  It is indeed
broadcasting serial numbers.  Early versions did shut down networking
if somebody broadcast a duplicate serial number.  For some reason
that was not popular :-)  Anyway, newer versions just print nasty
messages when that happens.  Networking does not shut down.
