I would setting promiscuous mode on the interface somehow notifies userland and dhcpcd retries getting an address. Can't say if it is a bug or not that dhcpcd renews its lease, but it might be the driver that is at fault there. Try using adding -p to the list of options of tcpdump, if you can afford it. -- 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.
