Fedora core 3, try to set up the network with "system settings" "network" it shows eth0 there and looking at the details it all seems normal, but when I try to
activate it, it shows it active for about 10 seconds and then goes back to inactive. I have searched many pages of similiar questions and tried many things. Doing /sbin/ifconfig looks ok, but it does not have a IP address. /sbin/route has no information, only the headings for the enteries.
do #ifconfig eth0 <ipaddress>, appears to work, but it does not get in ifconfig
do #route add -net 0.0.0.0 netmask 255.255.255.0 gw <gw address> get "network is unreachable"
do #route add -net <network quad> net mask 255.255.255.0 dev eth0 get
"no such device" Have done this using dhcp and with static ip addresses.
The computer is a IBM Think Pad 600X dual booting with win 2k which easily connects to the LAN!!!!! Have FC3 working ok on a old Pentium 3-450 desktop that works just fine, I have tried to see where the difference might be, but have not been able to identify it. By now this is driving me nuts, can anyone help?

try this and see it this works:

route add -net 0.0.0.0 gw <ipaddress>

For ifconfig try using the 'up' switch which tells it to enable the device:

ifconfig eth0 <ipaddress> up

try to ping yourself from your own computer using your IP and see if it times out after some time as you are sayin.............

To fotoguy - when do the suggested route add .....get
SIOCADDRT: Network is unreachable
and the ifconfig suggestion it does not get entered into ifconfig the next time I execute it??
To ALinux, do ping for the ipaddress of the computer - get network is unreachable.
Thanks for your suggestions, but no winner yet!

If there's no IP, you're going nowhere but loopback.

So there is a DHCP server running.

You may need to run a DHCP client.

Try it manually. Here are two of my earlier posts on the subject:
http://www.linuxquestions.org/questi...86#post1801286
http://www.linuxquestions.org/questi...44#post1780244

Once you see if that solves the problem, you can worry about getting it into your init scripts

To: archtoad6
At first I had no results trying dhc <tab>, so installed the dhcp - A DHCP from the Fedora intall sw. Now when I do the dhc<tab> I get:
dhclient dhcp6c dhcrelay
dhclient-script dhcpd
Still have an empty route table and no IP address in /sbin/ifconfig
Note, I am running this computer with a static ip address, so wonder if the dhcp is necessary?
I looked at your posts and tried to follow them as best I could. Any further help will be appreciated.

Can you easily verify there is a DHCP server running on your LAN? It's probably on you router. I assumed this because W2k was connecting, but it's possible you configured it w/ a static IP.

Assuming there is a DHCP server running, run as root:You might also read, even post if it's not to long or wide, dhclient-script .

I hope I'm not missing something in your Q.

Here is the result of doing dhclient
[root@localhost /]# dhclient

I could not find a dhclient-script file - does that mean something?
There was a dhclient-eth0.conf file, but it only has one line that said
"send host-name "ibm"; temporary RHL ifup addition"
Yes there is a dhcp server running, it is in the Linksys router and it assigns ip's to all the
orhter computers on the network, mostly Windows, but do have 2 or 3 Linuxes running some of the time. This is really a mystery to me!

I found the dhclient-script file, it is about 12.9kb, if that will not cause a problem with the
forum I will send it on a post, or is there another way?

Quote:

... dhclient-script file, it is about 12.9kb

How many lines is that?
Does it look interesting?
UPDATE: I am sitting in a room a Linux users, one of whom just read me the 1st few lines of /sbin/dhclient-script; don't bother posting it -- it's waay too long to clutter the forum with & almost sounds like a bad joke.


Vis-a-vis the real problem -- Would you be willing to try one of the live CD's?

• Knoppix -- great auto-detect, KDE default
• SImplyMEPIS -- good auto-detect, KDE default
• Ubuntu -- good auto-detect, GNOME default

It's not clear whether you have a Linux problem or an FC problem, or perhaps a hardware problem. (It's being jokingly suggested that you have a "Win NIC").

Yes I can try the live CDs I have Memphis, Atmission, and Knoppix. But be advised I know about win nics, this particular pccard has been used with Lycoris, and Red Hat 9.on the same compuer, so that can not be an issue!!!! So is it worthwhile to do that?

Does fedora core 3 have a /etc/rc.d/rc.init1 file?

If it does you maybe able to edit the script and manual add the configuration, this file is used a startup to configure the nics. Slackware 9 has this so it maybe the same for fodora, if you have it, it may look something like this:

#! /bin/sh
# /etc/rc.d/rc.inet1
# This script starts up the base networking system.
#
# Version:
# @(#)/etc/rc.d/rc.inet1 8.1 Tue May 28 15:27:39 PDT 2002 (pjv)

# Edit these values to set up your first Ethernet card (eth0):
IPADDR="192.168.1.15" # REPLACE with YOUR IP address!
NETMASK="255.255.255.0" # REPLACE with YOUR netmask!
# Or, uncomment the following lines to set up eth0 using DHCP:
#USE_DHCP=yes
# If your provider requires a DHCP hostname, uncomment and edit below:
#DHCP_HOSTNAME="CCHOSTNUM-A"

# Edit these values to set up your second Ethernet card (eth1),
# if you have one. Otherwise leave it configured to 127.0.0.1,
# or comment it out, and it will be ignored at boot.
IPADDR2="127.0.0.1" # REPLACE with YOUR IP address!
NETMASK2="255.255.255.0" # REPLACE with YOUR netmask!
# Or, uncomment the following lines to set up eth1 using DHCP:
#USE_DHCP2=yes
# If your provider requires a DHCP hostname, uncomment and edit below:
#DHCP_HOSTNAME2="CCHOSTNUM-A"

# Edit the next line to point to your gateway:
GATEWAY="192.168.1.1" # REPLACE with YOUR gateway!

Whats the output of


ifup eth0

when run as root

To: archtoad6 - I tried a live CD - without success, probably because that Linksys card is not listed in their eth0 card selections. That with your question about whether it is a "Win" eth0 card (even though it had previously worked with two other Linux distros) caused me to change to a 3com 3c574-tx card which is listed in the available cards. This was last night - and it worked just like it should, ifconfig had a IP address and I could connect to the LAN! BUT this morning it was back to the previous condition - no ip address in ifconfig and could not activate the eth0 card! Ugh - how disapointing. Any further suggestions please?
To: fotoguy - Fedora Core 3 does not seem to have a /etc/rc.d/rc.init1 file. In /etc/rc.d there are the following: init.d, rc, rc0.d, rc1.d, rc2.d, rc3.d, rc4,d, rc5.d, rc6.d, rc.local, rc.sysinit.
Maybe one of these has the info you are looking for?
To: abhijeetudas - The output of ifup eth0, ran as root is:
"Determing IP information for eth0....hdclient (4803) is already running - exiting failed"
Thanks for all the responses - please keep trying!

1. the reference to a "Win NIC" was a joke from one of a room full of Linux geeks. -- I was at our regular Wed. Linux Workshop & had access to a bunch of other talent. None of us has ever actually heard of such thing. Sorry if it caused you extra work, I was trying to make the tongue-in-cheek nature of the remark clear.

2. Which live CD did you try? Esp. what did Knoppix report or did MEPIS work?

3. I am beginning to lean toward "FC3 doesn't like you or maybe your NIC" -- i.e. I am almost stumped.
