I thought altq(4) could also do most of what dummynet(4) does but based on a closer look, it seems that it can't do the packet delay stuff, though it seems to have fairly similar bandwidth management facilities. >is the main selling point for ipfw on my servers -- being able to rate=20 >limit arbitrary IP addresses, port numbers, etc, both in terms of inbound= =20 >and outbound traffic is invaluable. I extensively use dummynet at work to simulate WANs (bandwidth limited and significant delays) between different servers in our models. It has proved invaluable for relicating field problems. --=20 Peter Jeremy --VbJkn9YxBvnuCH5J Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGNdTr/opHv/APuIcRAklGAJ943tw20evFrgxDlhb4xgYhTueH1ACfXaaH wvO0+1f/pxAZHaQpQXYVRnM= =9Vk8 -----END PGP SIGNATURE----- --VbJkn9YxBvnuCH5J--
