OK, I've confirmed that I still get the above with both dadwifi and bcm43xx-mac80211 A tcpdump indicates that my laptop sees its own neighbour-announce come back, and assumes that's a different machine sending it, failing the duplicate address detection. A tcdump against the ethernet device (or bcm43xx from 2.6.20) does not see the neighbour-announce come back, and so passes the duplicate address detection, and gets an autoconfig IPv6 address. I thought it might be the lack of IFF_BROADCAST which was fixed a while ago, but it's still there. kernel 2.6.20 from debian, patched with get_order() fix from 2.6.20.2 modular mac80211 stack from intel's 4.0.4 tarball, patched into kernel bcm43xx-mac80211 from wireless-dev dadwifi from madwifi.org subversion repository --=20 ----------------------------------------------------------- Paul "TBBle" Hampson, B.Sc, LPI, MCSE On-hiatus Asian Studies student, ANU The Boss, Bubblesworth Pty Ltd (ABN: 51 095 284 361) Paul.Hampson@Pobox.Com Of course Pacman didn't influence us as kids.
