The source code is in, /usr/src/sys/netinet/if_ether.c The error message is generated by the arplookup() routine. arplookup() is called in arpresolve() and in_arpinput(). I've seen these messages too (usually from misconfigured machines). I am not _exactly_ sure what is prompting the machine to try to do an arp lookup on a machine that is not on the local network, but it may be that for some reason the machine's in question sent a packet directly to the host and it is doing a sanity check on the packet. A guess. -- Crist J. Clark cjclark@home.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
