determining ip information for eth0...failed
 
before i get into the error let me tell you a bit on the background so you can all get a clear picture.

Ok the 1st time I installed Redhat 9 I was getting an error saying....

Dertermining IP information for eth0....failed - no link present check cable?

I added this to the /etc/sysconfig/network-scripts/ifcfg-eth0 script:

check_link_down() {
return 1;
}

And it worked - i got an ok when it was bringing up eth0.

However.......

I just reinstalled rh9 in exactlly the same way on exactlly the same computer with exactlly the same hardware.

and when i modified the ifcfg-eth0 script again i got......

dertermining IP information for eth0 failed
iptables...no chain/target/match by that name
iptables...bad rule (does a matching rule exist in that chain?)

so i turned the iptables firewall off and now i get.....

Dertermining IP information for eth0...Failed!


I just don't know what else to do - please someone help me - why has this message only just starting to come up now when nothing has changed on the computer?!

also it works fine when I connect to it via win98 (I had it on a spare hdd) in the same computer.

Im at the end of my thether now!

thanx in advance....

also if you need any more info from me such as what the output of a command is or the contents of a file let me know and i will tell you - i am going to be online for a good few hours yet so i can reply almost straight away!

This is a boot up trying to connect in promisc to locate a dhcp server.
The system waits about 1 minute???
Then the failure.is that the DHCP server is not found.
Is the system set for a static IP
You can use redhat-config-network to make corrections or check the configuration.

It needs to be dhcp as it is for my broardband connection. i think that was what you was asking - sorry im not very good at all this.

From man ifcfg:

EXAMPLES
ifcfg-eth0 configured for DHCP:

DEVICE=eth0
BOOTPROTO=dhcp
NETMASK=255.255.255.0
ONBOOT=yes

Hope some of this helps..

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
