    Newbie, problem with: SIOCSIFNETMASK: No such device

    Hi everybody, I've just installed Fedora and getting in touch with Linux for the first time. I'm triying to configure the IP address with this command I've found in a tutorial:

    ifconfig eth0 netmask up

    but I receive from the bash this answer:

    SIOCSIFNETMASK: No such device
    SIOCSGIFADDR: No such device
    SIOCSIFBROADCAST: No such device unknown inteface: No such device

    which is the problem?
    I'm logged as root.

    I think your NIC is undetected. What if you just do 'ifconfig'? You should see your device 'lo', and if your NIC is detected, you should also see several lines for 'eth0'. If it's not detected, you may need to 'modprobe' the correct driver. What kind of NIC is it? Once you know what driver it should use, do 'lsmod' to see if the driver is listed. If it's a PCI slot NIC, do 'lspci' and see what returns for the NIC. If it's an ISA slot NIC (older box), there may be a couple of other configuration steps needed. If it's a USB NIC, it could get more complicated....
