I'm on an Ethernet. BOOTP doesn't work. You mean ethernet address for bootp, not IP address? Your IP address is assigned to the machine by your administrator. If you boot using BOOTP, then part of the rc is to run /etc/netstart to start up networking -- and to bind your assigned IP address to your interface. If your machine is up and you can telnet into another host, then the command "who am i" at the shell prompt should return your host name, or your IP address, if RARP is incorrectly configured, that you used to telnet in. >From there, you can type "arp -a" (or "/usr/sbin/arp -a") to get a name-to-ethernet-address mapping for your host.
