Hi! Got following issue: I have my workstation running 4.0 Release (german Lehmanns dist) with a generic Realtek NIC configured (for several reasons) as non-PnP ed0. Everythings working so far. For using DHCP support on our dorm's network (and to obey local policy ;-) ) I wanted to use it. So I compiled BPF into the kernel, and it works. But one thing troubles me: At least under 3.2R , there was a boot-up message saying :ed0 promiscuous mode enabled Problem is, that another part of local policy forbids cards being in promisc mode due to possible sniffer attacks etc. Questions: (man bpf left some questions open) Can I assume. that with the presence of bpf the card is _always_ put in promisc. mode? If thats the case, are there any other thinkable ways to use the DHCP service for automatic IP assignment? And, final one, to be prepared for heated discussion with local admin: In which ways does Linux do DHCP? (He is some hardcore Linux guy) TIA Olaf Hoyer -------- Olaf Hoyer www.nightfire.de mailto:Olaf.Hoyer@nightfire.de FreeBSD- Turning PC's into workstations ICQ:22838075 Liebe und Hass sind nicht blind, aber geblendet vom Feuer, dass sie selber mit sich tragen.
