This is not right. Guess I was typing "man" in the wrong xterms.
FreeBSD (4.x, 5.x) listens to the network by default (and can be persuaded not to with a "-s" flag). NetBSD (1.6) does the same.
You were right the first time, at least for FreeBSD. The "-s" flag is applied by default - see /etc/defaults/rc.conf . Not quite as idiot-proof as a compiled-in default, but way better than defaulting to listening.
The same is true of NetBSD 1.6; look in the same place. --Steve Bellovin, http://www.research.att.com/~smb (me) http://www.wilyhacker.com (2nd edition of "Firewalls" book)

Serves me right for contradicting myself.
