If the noafif() interface list includes a network interface which can have an address, it is a bug and the interface should be removed from the list, though. -- Hiroki [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iEYEABECAAYFAk57YMcACgkQTyzT2CeTzy2n2gCgn0vGp6FY2wYCgmJbYkv3n9qW QfwAoL/6endJCd68AdRCwC/jj7ItCe6P =yDGA -----END PGP SIGNATURE-----
