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,

eth0: Identified 8139 chip type 'RTL-8100B/8139D'

eth0: link up, 10Mbps, half-duplex, lpa 0x0000
The output of "cat /proc/ioports" is:

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'

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.
