>Description:
It appears that UDP servers listening on a specific interface
address/socket pair do not receive broadcasts on those interfaces,
and/or inetd(8) doesn't fork off such servers when broadcast packets arrive.

>How-To-Repeat:
Bind "ip-address" as an alias on an ethernet interface.

Put a line like this in your inetd.conf:
ip-address:netbios-ns	dgram	udp	wait	root	/usr/local/samba/bin/nmbd nmbd

Cause another host on the network to send a UDP broadcast to this port.

Watch that inetd never forks off nmbd.
