Bikeshed apart, what about: rp> # ifconfig fxp0 -nd6 (to disable ND6) rp> # ifconfig fxp0 nd6 (to enable it) This is actually "ifconfig fxp0 *inet6* ifdisabled". The reason why I used this name is ndp(8) uses "disabled" and the flag constant is named as ND6_IFF_IFDISABLED. The "ifconfig fxp0 inet6 -nd6" is technically correct, but it sounds rather cryptic from viewpoint that we use it as a flag to disable IPv6. It means disabling NDP as well as marking all of the AF_INET6 addresses on that interface as IN6_IFF_TENTATIVE. Hm, actually I do not stick to the name "ifdisabled". Is "nd6" better? -- Hiroki ----Security_Multipart(Sun_Jun_28_08_35_34_2009_561)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAkpGrMYACgkQTyzT2CeTzy1XAQCffG6CpCWqMnRXoN0qkvMzeAOL QvAAoJi5h94Zwj/58EdZs/27NxwR435R =riKr -----END PGP SIGNATURE----- ----Security_Multipart(Sun_Jun_28_08_35_34_2009_561)----
