Hi

I have an issue regarding configuration of IP to my linux machine.
I have installed linux EL4 on intel machine(with gigabyte motherbaord, sata hard disk, Edimax lan card) since realtek was not supporting it.

errors in configuration of ipaddress in Linux EL4:
The mother board is gigabyte and LAN card was realtek. When we tried to assign ipaddress we failed.
Later we add another lan card from EDIMAX
now when we assing ip adress locally it takes.
but when we give it static it fails.

when i assingn MANUALLY(STATIC):
#netconfig

root@localhost ~# service network restart

Bringing up loopback interface: OK
Bringing up interface eth0: OK
root@localhost ~#

everything works quite good.

But the problem is that i cannot ping to other machines in my LAN.
eventhough I gave the gateway subnet,....

root@localhost network-scripts# ifconfig -a
