[SOLVED] Need to Re-build my Network

D_Redd · 02-01-2010, 10:55 AM

I just recently rebuilt my RHEL 5.3 system using MONDO onto differnt hardware. The tool worked GREAT on my 32 bit system. The only problem I am having now is that since this system was built as a clone of another system on different hardware, it copied over the network definitions as well. Not good!!! So although my system is up, I can't get it on the network because it still wants to use the original NIC's that were on the other system.

How can I blow away all network hardware definitions and tell the system to go out and re-discover so that I can configure them with the nessasary network information. PLEASE HELP.

Thanks in advance..

can you please post the output of:

Code:

lspci
lsusb
ifconfig
iwconfig
ifconfig -a
lsmod

Doesn't use udev? couldn't you edit udev rules, to see if that prevents your new NICs to get detected properly?

will sudo dhclient refresh the network parameters ?

D_Redd · 02-01-2010, 03:22 PM

Fixed it. I had to delete all my network devices in /etc/sysconfig/network-scripts; then re-add the hardware devices mapping them to the eth* that I desired using the $:neat mapping gui. Once that was done, I just restarted network services (service network restart). and everything came up!

Thanks all for trying to help..
