You don't need RARP except for a diskless boot. RARP says, "Here I am (with MAC address ...); what is my IP address?" To find the IP address of a MAC interface *which*your*machine*has*seen*, use `/usr/sbin/arp -a -n' (the -n returns the IP address rather than the name). I don't think that there is any way to find the IP address of an arbitrary MAC device which isn't on the current network. -- Oliver Elphick [EMAIL PROTECTED] Isle of Wight http://lfix.co.uk/oliver PGP key from public servers; key ID 32B8FAA1 -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
