I'm on an Ethernet. BOOTP doesn't work. Huh? Maybe it's the beers that have done it (to all that give a damn, the customers gave the hardware a 100% thumbs up, including the cluster of FreeBSD machines running the radar and processing the test data - we even made half a dozen photocopies of the FreeBSD CDrom covers 8), but I can't work this out out. Either : You have a machine coming up and you want to work out what address it should have (1), or you're on a machine and you want to find its IP (2). For (1), BOOTP will only work if you have a server previously configured for it on the network. Assuming this is met, then BOOTP certainly _does_ work. For (2), try 'ifconfig -au' for a list of all of the interfaces that are up on the system. > Ivan -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
