Ethernet/connectivity problems RH 9


A friend asked me to do a fresh install of RH 9 with a LAMP install and Qmail - he mailed me his box from W. Va., I did the install, and everything worked fine with my cable modem. He's 800 miles away and knows nothing about Linux and I'm no Linux whiz either - but I've done these installs 30 times and never have had any significant probs. He just got a cable modem and it's working (with other PCs). He has this PC on the cable by iteslf, however and has no firewall of any kind. At first his ethernet detection failed during boot, then eventually worked. Still - he cannot connect to the net. He emailed me with the following error:
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2018ms, pipe 3 failed
We've tried removing the ethernet card physically, reinstalling the card, deactivating the device then reactivating, etc.

Anyone have a clue as to what the prob is....I had never done this sort of install and then switched ISPs, which I guess is the problem....

Any help would be greatly appreciated

Hi,

the first thing you can do is execute kudzu :
Code:
/usr/sbin/kudzu -p
This shows you an output of the hardware your RH9 system detects. If your network device is listed you can configure it with the help of 'redhat-config-network'. Both has to be done as root.

If this dosen't work, post the error messages here.

Hope this helps ...

If he is switching one cable modem between a few different pc's make sure he power cycling the cable modem (unplugging it) when switching the connection (if he is using a router it doesn't matter though). A cable modem will remember the mac address of the pc it is connected to until power cycled. You can also post the output of /sbin/ifconfig to help.

Argh - appreciate the input but I made need to query the insurance dept. at UPS.......can't do that from the comand line. He told me that "some cards got pushed out" during shipment and he'd powered it up before pushing them back in....I ruined the first PC I ever built in a similar fashion. Think we have a major hardware failure - just PM'd me that the processor has turned itself off, etc. What a mess.....thanks, though, guys.
