Hi there!

I've just installed Redhat 8.0 and each time it boot I got the same problem. It says "Determining IP information for eth0... failed; no link present. Check cable?". When my system his fully loaded I just have to do a "ifup eth0 in a shell and it work after 2 or 3 times. I change my module "tulip" to be autoclean and restart the network and its still doing the same thing.

my eth0 is hooked up on a cable modem
network-script: bootproto: DHCP
onboot: yes

in my var/log/message:
Its sending DHCPREQUEST multiple times before dropping.
then like i told before.. when I'm in my shell.. I do ifup eth0 and it work...
I just dont understand hehe..


I'm thinking to re-compile the kernel.

Do anybody have an other option?

thx

Have you tried another cable? Sometimes the pins can work their way loose in the lug/connector.

I've change the cable and its does the same thing...

Suppose the cable is good.
Have you enabled DHCP on the cable modem? DHCPREQUEST without any reply message means your DHCP server does not respond.

Here is the msg I have when I do it manualy on the shell (var/log/msg)

dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67
dhclient: DHCPACK from 10.48.128.1
dhclient: bound to 24.200.x.x -- renewal in 40198 seco
nds.

Its only on the boot sequence that it the eth0 just dont start....


I really appreciate your help at the moment guys thx))

possibilities:

1. your cable modem is doing MAC address caching. you initially connected with a different network card, and therefore, not getting an address for your current nic. unplug your cable-modem for several minutes, or otherwise try to reset it, and try connecting again. its also possible, that your cable provider only provides DHCP service to registered MAC addresses. if this is the case, provide your cable company with the MAC address of the NIC on your linux box.

2. your cable provider is using a private IP for the DHCP server, and response packets are being dropped by the firewall rules. check something like /var/log/messages for denied packets. you might try disabling IP tables in using the GUI for network services. this might not seem possible since you are able to connect after the IP tables have loaded. however, i think i recall that many firewall rules load a stringent set of rules temporarily until the ordinary rules can complete loading.

I have RedHat 8.0 and on that version the friewall his automaticly setup by the system and you can't change it until you go clean /etc/sysconfig/iptables.
So I did clean that one up just in case there were no bad configuration on the startup.

I've look trough /var/message and there is nothing about packet denied....

MAC related problem was'nt the case because I'm still able to hook up after I do it manually on a shell..

Here is a summary of my log:

startup:

Jan 14 14:01:15 noise network: Setting network parameters: succeeded
Jan 14 14:01:16 noise network: Bringing up loopback interface: succeeded
Jan 14 14:01:16 noise ifup:
Jan 14 14:01:16 noise ifup: Determining IP information for eth0...
Jan 14 14:01:21 noise ifup: failed; no link present. Check cable?
Jan 14 14:01:21 noise network: Bringing up interface eth0: failed
Jan 14 14:01:23 noise network: Bringing up interface eth1: succeeded

Then.. on my shell:
after I do ifup eth0 manually

Jan 14 14:02:45 noise dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67
Jan 14 14:02:45 noise dhclient: DHCPACK from 10.48.128.1
