In order to remove the need to run ipfw(8), I am looking at migrating to altq(4). Unfortunately, whilst altq(4) provides bandwidth management, there does not appear to be any provision for providing time delay on packets. Has anyone looked into implementing time delays in altq? --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --aM3YZ0Iwxop3KEKx Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkg/Ad0ACgkQ/opHv/APuIetJwCgiC4BpU3lHYZNqzEZMaDkeJEn v4kAnRfdNYP2rZc64kXdKGFsiyYMuzEB =FvQY -----END PGP SIGNATURE----- --aM3YZ0Iwxop3KEKx--
