Re: cable connection stopped working
Yeah, apparently some of the modems memorize the hardware address of the ethernet card, so if you change the card, you have to turn off the modem for a few minutes. -chris On Wed, 30 Aug 2000, Michael Smith wrote: BTW, I've hooked up several boxen to @home, and sometimes the modem needs to be turned off.

cable connection stopped working
I have a cable connection to [EMAIL PROTECTED] It worked under linux. I now have a new machine. Even with the same ethernet card as the old machine, I can't get the connection going. Same settings, same ip address, no dhcp (don't need it says Rogers, since my ip hasn't changed). I can up the eth0 interface, no errors, but pinging any host on the internet does nothing: the ping just sits there (Same thing for telnet). tcpdump occasionally reports one or two lone responses from the DNS host. This after a minute or so. iptraf reports some UDP stuff, almost all of it outgoing and not incoming, but no tcpip stuff. tried changing ethernet cable. The lights on the cable modem flash a bit when I ping, as expected. Can someone suggest how to debug this sort of thing please, it's been four days and three ethernet cards already and I'm running out of ideas. -chris

Do cable modems act as a gateway? I have DSL and you may have a similar situation I had. I don't know how much dsl is to cable modems. Paul
Re: cable connection stopped working
Can you ping your default gateway? Also are you running a internal network? -- Original Message -- From: Chris Majewski [EMAIL PROTECTED] Date: Wed, 30 Aug 2000 11:28:22 -0700 (PDT) I have a cable connection to [EMAIL PROTECTED] It worked under linux.

Re: cable connection stopped working
First of all, I just got the connection working. Thanks to all. Using the correct NIC driver did the trick, though note that I did try two different NICs earlier this week with negative results. To sum up: isapnp 3c509 no longer works (although the driver reports no errors), pci NDC card with tulip driver similarly, 3c905b works. As for your questions, I would like to answer them but don't know how. My /etc/network/interfaces does have a gateway entry in the eth0 section, it is similar to my ip address but the last number is different. -chris On Wed, 30 Aug 2000, Paul T.McNally wrote: Can you ping the cable modem?

Re: cable connection stopped working
Hm, I can't remember if I tried pinging the default gateway before I got the connection going five minutes ago. No I'm not running an internal network and never was. Anyway I'm glad it works now but still shaky on the network problem diagnosis issue.. if I hadn't been stubborn and tried 3 nics i might have wasted another couple days on this.. hmm chris On Wed, 30 Aug 2000, Ray Percival wrote: Can you ping your default gateway?

BTW, I've hooked up several boxen to @home, and sometimes the modem needs to be turned off. That's my big troubleshooting step if I can't ping the outside.

It's a step we take all the time on our CSU/DSU units (some people call them modems). Bottom line is that it works. They are old outdated pieces of crap, but they do the job for now.
