Which internet standard it might be > referencing to. The first thing that comes to mind is that FreeBSD doesn't pass on network broadcast packets by default. This violates RFC1812 , which mandates that subnet broadcast packets must be passed on as specified in STD3 . This actually is no longer good practice, so I'd say it's more prudence than an outright design flaw that FreeBSD doesn't comply with this. -- -- Skylar Thompson (skylar@cs.earlham.edu) -- http://www.cs.earlham.edu/~skylar/ --------------enigE531468BE1618695A0C99DA5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Cygwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFB0ePhsc4yyULgN4YRAnffAJ9rNtScAYToVLf5tyKT41tQMNo0yACfc6Vj 37CQErxjwJs/ihZvHD1MJSE= =fM7i -----END PGP SIGNATURE----- --------------enigE531468BE1618695A0C99DA5--
