(So now, why can dhclient cope with promiscous > mode?) It's actually because dhclient is stupid: if you unplug the cable and then plug in a different network, dhclient won't notice it. That's one of the many improvements of dhcpcd. Now, why does dhcpcd gets triggered in your situation remains to be explained, but I tend to believe it would be a bug in the driver rather than in dhcpcd. -- Quentin Garnier - cube%cubidou.net@localhost - cube%NetBSD.org@localhost "See the look on my face from staying too long in one place [...] every time the morning breaks I know I'm closer to falling" KT Tunstall, Saving My Face, Drastic Fantastic, 2007.
