I did not define accept_rtadv in rc.conf nor is it fr> enabled via sysctl. net.inet6.ip6.accept_rtadv is set to 0 (default) An interface on FreeBSD 8.x accepts RAs only when net.inet6.ip6.accept_rtadv=1 *and* ACCEPT_RTADV is enabled at the same time. This has been the default behavior regarding RAs for a long time. A new thing on 8.x is that the interface option ACCEPT_RTADV is exposed in the ifconfig output. This flag was actually enabled by default prior to 8.x, too. -- Hiroki ----Security_Multipart(Tue_May_24_18_09_01_2011_319)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iEYEABECAAYFAk3bda0ACgkQTyzT2CeTzy0bPACg1ZaOAf6I9aMBlcjwcH3S29/l LYEAoMNF+WLvt+gHP/8bZfdLA5OFgbEY =1n49 -----END PGP SIGNATURE----- ----Security_Multipart(Tue_May_24_18_09_01_2011_319)----
