No network connection, unable to ping netgear router from RH Linux

alak123 · 05-03-2006, 12:56 AM

Hi,

I recently partitioned the hard drive on my PC and installed Redhat 9. I have XP on the other partition. While I am able to access the network and ping the netgear router from the XP partition as well as from another XP laptop linked to the router, I am unable to do so from Linux.

The PC has an Intel EtherExpress/100 NIC. The NIC was not automatically recoginized during installation but seems to be ok after I installed the drivers. Could this be causing the problem?

I setup DHCP through the Network Configuration gui. dhclient returns with "No DHCPOFFERS received"

ifconfig does not show an IP address assigned to eth0.

Any suggestions?

Thanks!

if it was me, I would go to a shell prompt and type "setup" there is a text driven "gui-ish" menu that pops up and allows you to play with a bunch of settings from FW to network to keyboard, etc. I would start with redoing the network config, and then I would check the FW settings. I've also notice wierd nuances with selinux enabled, I generally disable it until I'm done building an image, and then re-enable for production.

please post the output of the following..

lsmod

ifconfig -a ( must be root for this one to work on RH9 )

more /etc/sysconfig/network

more /etc/sysconfig/network-scripts/ifcfg-eth0 (the card is eth0 right ? )

Hi farslayer,

The card is eth0.

I tried setting up using this menu. No luck...I still get the same error. How do I figure out if the problem is with my NIC or with the way the m/c is communicating with the netgear router (RP614)? Would getting a new router help? Thanks!
