Julian- The patch worked. Everything seems to be working fine now. The patched seem to fix both the DHCP issue (the kernel panics) and the ARP issue. One quick question though, if I do decide to go the node route, can you suggest any reference on mbuf packets? I don't care if its a book or website or man page, etc. I just haven't been able to find much, except the information I gleaned from reading through mbuf.h. I just figure there must be something else out there. So far my daemon is working the way its suppose to, but CPU usage gets pretty high (3% or more) when I'm testing with just one client box, so I'm worried about what may happen if I connect 100 or more. Anyway, thanks for all your help. - Ben Schumacher To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
