On board ethernet keeps dropping

[hpoko]

I have installed RH 7.3 on a intel motherboard PIII 1.2Ghz with built in motherboard. I have done the up2date and built it as a web server. For some reason the interface stops working and I have to bounce the interface to get it to work again. At first I thought it was a bad system but I build another box yesterday and it started doing the same thing. Would anyone have an idea why the interface keeps dropping out.

Thanks

I have RH7.3 installed on a Intel 810 motherboard with no problem. I don't think the issue is the motherboard but rather a setup problem that you are repeating on the 2nd system.

First, what is the make of the NIC? Do you have another NIC that you can use to eliminate the interface card itself as the offending element?

Secondly, is the card interface set to get IP address dynamically (DHCP) or is is set statically?
look at /etc/sysconfig/networking/devices/ifconfig-ethx

if dynamic it will have a line like this:

BOOTPROTO=dhcp

if statically assigned it will have the IP Address, Subnet Mask, and perhaps a Gateway address.

My guess is that you have it set for DHCP and there are two DHCP servers on your network (such as a W2K machine and a cable modem.)

Third, examine your logs for an answer.

Thank you for you reply and suggestions I added a 3com nic and it seems to be working fine. I am not sure why the onboard nic would drop out. I did try to check the log files and I could not see anything that was related to the interface dropping.

Thanks

It wasn't a Intel EtherExpress Pro100 (eepro100) by any chance?
