    Have you enabled the NIC cards and/or do you have the correct drivers loaded
    for Linux to use those NIC cards?

    Subject: Network Not Working in Linux ; Works in Windows Why ?

    Hi,
    I have just installed RedHat in my system (Dual OS : Windows and
    Linux)
    I can ping any system on the network under windows.

    But, when i ping any system on the network under Linux I get,
    Undestination Unreachable error.

    I have Inter Pro 100 Ethernet card on my system.

    The Static IP is same for Windows and Linux.

    When i do ifconfig ; i am getting ip, netmask everything is ok. except
    Tx Packets and Rx Packets which are 0.

    I tried

    cardctl ident

    I got an message saying no devices in /proc/devices.

    I dont know what is the problem.

    I checked The driver is e100 it is loaded. but still network is not
    working.

    Please advice.

    Would appreciate if you could tell me what (steps) i should do inorder
    to correct my problem.
