No, but a few more datapoints: - it only affects real network connections - localhost is unaffected - The problem also occurs when pinging FreeBSD 7.x from linux but not when the same linux system pings a Winbloze box. - Pinging either linux or winbloze from FreeBSD 7.x fails. --=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. --CpBQqYjq/d0HQTAP Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkh94cQACgkQ/opHv/APuIeuwACdG5508jNBAgINmXxgI9bG5ZmS F4kAn36jRss0DvTBpgcZMQs7xQ5Y4c7O =YjEY -----END PGP SIGNATURE----- --CpBQqYjq/d0HQTAP--
