    I'm unable to make contact with the internet. I get an "Unable to find
    IP
    address for server name "localhost.localdomain" - Host name lookup
    failure" error message. The step-by-step procedure I've followed so
    far.

    I have a Fast Ethernet 10/100M PCI network card from Genius on a linux
    PC running Fedora core 1, kernel 2.4.22-1.2115.nptl and GNOME. My
    system recognizes the networkcard, because at bootup, I see (using the
    command "dmesg | grep eth0"):
    eth0: RealTek RTL8139 Fast Ethernet at 0xc48bd000, 00:40:f4:6f:b4:90,
    IRQ 11
    eth0: Identified 8139 chip type 'RTL-8100B/8139D'

    eth0: Identified 8139 chip type 'RTL-8100B/8139D'
    eth0: link up, 10Mbps, half-duplex, lpa 0x0000

    The output of "cat /proc/ioports" is:
    0000-001f : dma1
    0020-003f : pic1
    0040-005f : timer

    So I presumed the driver is 8139too, which I loaded -I think-
    succesfully (using "modprobe 8139too io=0e400 irq=11"), because
    "lsmod" gives me:

    [note: yes, I am aware about the recent discussion on this list that the 8139too is not a
    good ethernet chipset, but I bought it because I originally had on my Windows-machine a
    USB to Ethernet convertor (USB LAN 100 from Topcom), that didn't support Linux; and I'm
    not very jumpy to run to the shops a third time.]

    I adapted /etc/modules.conf to:
    alias usb-controller usb-uhci
    alias eth0 8139too
    options 8139too io=0xe400 irq=11

    I'm not sure if that was entirely correct. Are 2 aliasses allowed? Is
    my choice for IRQ=11 correct? On "cat /proc/interrupts" both my
    ethernetcard and my USB are listed on 11, both won't this give any
    confusion?

    I then went on to configure my network with the command
    "redhat-config-network", which gives a GUI. In the tab "Devices" I
    selected "New" > Ethernet connection > RTL-8139/8139C/8139C+ (eth0) >
    automatically obtain IP adress settings with DHCP. When I then save
    and select my eth0, there is the error message "Determining IP information for eth0....
    Failed"

    If I start DHCP Client manually (command "dhclient"), I get the
    (error)message:

    In /var/log/cups/error_log.1 I find this line:

    address for server name "localhost.localdomain" - Host name lookup

    The command "ifconfig -a" gives this output. I notice that the IPs for inet
    addr, Bcast and Mask are missing.

    I don't understand much of DHCP yet, but on
    http://users.pandora.be/bdr/DHCP/dhcp.html the command "tcpdump -n -i
    eth0 -l -s 500 -x udp port 67 | tee dhcp_dump" was recommended to analyse problems. That
    gave me some output like this:

    I can't get much out of this, but sometimes I recognized something, like in:

    52:21.988678 81.83.160.1.bootps > 255.255.255.255.bootpc: xid:0x3abb2391

        4500 0160 f72c 0000 ff11 d20b 5153 a001
    Where "pandora.be" is the name of the ISP which provides me with dynamic
    IPs.

    Some more info that I was able to squeeze out of my machine:
    The contents of my /etc/sysconfig/networking/devices/ifcfg-eth0 file:
    USERCTL=yes
    PEERDNS=yes
    TYPE=Ethernet
    DEVICE=eth0
    HWADDR=00:40:f4:6f:b4:90
    BOOTPROTO=dhcp

    The following came from a log file. A lot of things are not yet filled in.
    Should I change and add them in in ifcfg-eth0 manually, or should dhclient
    (or some other program) do that for me?
    Mon Mar 29 10:10:31 2004: -+ //etc/sysconfig/networking/devices/ifcfg-eth0
    NETMASK=''
    DOMAIN=''
    BOOTPROTO='dhcp'
    HWADDR='00:40:f4:6f:b4:90'
    DEVICE='eth0'
    IPADDR=''
    DHCP_HOSTNAME=''
    TYPE='Ethernet'
    GATEWAY=''
    PEERDNS='yes'
    USERCTL='no'
    ONBOOT='yes'
    NETWORK
    BROADCAST
    DOMAIN
    DHCP_HOSTNAME
    IPADDR
    NETMASK
    GATEWAY

    That's about as much information as I can give you.
    Where did I go wrong, or what did I forget?
    Thanks for the help.

    Jeroen
