Hey All, I tried tcpdump with the appropriate flags and was able to see my gateway. It was responding to arp's from my IP. So, i thought that perhaps my modem was indeed my gateway and the @home people were just incorrect. I then portscanned the gateway (nmap) and found telnet open (23). I

Just a note in the fray: My cable modem has no MAC address. It is bound (via something the cable company set up on installation) to my specific network card's mac address. Walt -~ The size of one's feet bears no relationship to the ease with which they can be inserted in the mouth.

Hey Kelly, Funny that you mention compiling rarp into the kernel. I have just sat down to compile in Bastille Linux (kernel security) into my router. I just finished creating another 486 to use as a router while I take this one down. I'll check it out and see what happens. Thanks again for you

Hey Kelly, Yeah mine doesn't have a MAC addr on it either. Unfortunately traceroute give me a hop from my ethernet card directly to my gateway. So I guess for now I'm outta luck. Thanks for all the help Harry Hoffman Product Systems Specialist Restaurants Unlimited Inc. Seattle WA 206 634-3082

Hey Nicole, I did indeed try it, that's how I came to trying arp instead, ref. in man pages. Neither seems to do the trick. As for the how-to's none that I've found have described a simple switch (modem) as opposed to a router like the Cisco series for DSL. Thanks for the link. I haven't seen th

Have you tried it? (it doesn't sound like it) :o) You might try linuxconf or netconf or something that accesses your network configuration also... tho if it's not in ifconfig I don't know/think it'll be there. Have you tried looking at a howto for cable modems? http://www.oswg.org/oswg-nightly/o

Hey Kelly, I don't know if that is normally the case, however I would think that it would not be. The reason that I say this is that the cable modem is not directly connected to the computer. It is connected thru cat5 cable. ifconfig reports (I may be wrong here) on system devices only. Arp sho

Hey Jane, I'm not sure how tp run ifconfig on it. Normally, you have a cable modem that plugs into the ethernet card on the computer. So, when you run ifconfig it reports on your computers ethernet card not on the ethernet on the modem. So I'm kinda stumped. Thanks, Harry Hoffman Product Syste
