Is there a way to force the sending >of these messages for all the addresses of an interface? The kernel should send out gratuitous ARP requests whenever you assign an address to an interface. You could confirm that this is happening by tcpdumping the interface whilst you add aliases. Rummaging around in ports, you might find net/arping or net/p5-Net-ARP useful if you want to manually generate gratuitous ARP requests. --=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. --g7w8+K/95kPelPD2 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkhklVUACgkQ/opHv/APuIcz3QCgrwfIbdm214/HD2yZD5P7cgIS aJ4An2iMEy5dE9PQO2RmZfVZEf0cxUkp =bWWo -----END PGP SIGNATURE----- --g7w8+K/95kPelPD2--
