Chris, The code in "arp" that you're looking at does more or less the same thing as "route get" does, so try "route get ip.ad.dr.ess" to see what it has to say. Basically, the "cannot intuit" message means that when arp got the route for the destionation you're trying to set, it got a gateway route and not an interface route, meaning either that destination is not on a local subnet or your routing table is confused. If you want to learn more about routing sockets, I'd suggest "TCP/IP Illustrated, Volume 2" by Richard Stevens. Chapters 18, 19 and 20 cover the routing table and routing sockets, and chapter 21 covers ARP. Bill
