I've successfully jogged my memory and setting the window sizing to 65535 is for ipf's, IMHO, broken handling of TCP window sizing. 65536, ftp proxy breaks, 65535, ftp proxy works. This took quite a while to diagnose and should show up in the eratta someplace and it doesn't look like it's fixed in the most recent version of ipf, even though there was work done on the ftp proxy. :-( Anyone know if ipfw handles window sizing correctly, I haven't tested it yet to see if it does or not. -sc --=20 Sean Chittenden --a6Ri6/t33sscKOaw Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Comment: Sean Chittenden iD8DBQE9iM5ajoUuCl9bPssRAjFnAJ0WRVvL3tssejeHblIsG4jGsTwakgCeKA8d cH2KD28Vn80iXlhNi39n7G4= =IPDv -----END PGP SIGNATURE----- --a6Ri6/t33sscKOaw-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
