hi,
i am facing some problem in network configuration for linux.
i have installed a linux 7 .but it fails to identify my NIC
card.

when i gave the command ping localhost ..it worked..

for command "ifconfig"
-- it shows only the status of lo. and the status of eth0 is showing as inactive

i tried running the network script.."/etc/rc.d/init.d/network start"
it shows:

SIOCADDRT: File exists
Delaying eth0 initialization..

for the command "/etc/rc.d/init.d/network status"
it showed:

configured device:
lo eth0

devices that are down:

devices with modified configuration:


And while restarting its showing some error msg like invalid parameters in insmod module....unable to initialize eth0.

Network and everything seems to be perfect....what could be the problem ???

Have you recently changed anything on the box, or moved the OS from one box to another?

Could you do a few things... and paste them...


cat /proc/net/dev
cat /proc/pci
ifconfig -a
netstat -nr
lsmod

Do that, and we can go from there...

I received an error like that when my kernel wasn't compiled with proper chip set. If your NIC uses Tulip chipset make sure the .config file including Tulip as being enabled. Make sure your kernel supports the NIC.

Before PCQlinux 6.1 was there in that system after that I installed Redhat 7.2 and Redhat 7 but I'm facing the same problem

I tried various options but no luck and finally thought to reinstall the OS, then I reinstalled Redhat 7.2 hmmm...now its working perfect !!!
