no network connectivity (cable modem)

[clevisvb]

I have two NICs installed on my Linux Box. both are using the 3c90x driver provided by Red Hat Linux 7. Both are being seen and both are seeming to work for the most part.

When I start up and the computer runs through the menu, i am always getting a eth0 operation failed. Not only that but I can not seem to start up the ethernet card on my Cable Modem. Cable One said that DHCP should work, and I actually had it working one time, but then I shut off the computer and restarted tot he Operation Failed. What do you think my issue could be?

I can not seem to get it to work at all.

I have tried using dhcpcd, and it goes to the next prompt without an error, but nothing happens.

Hi ..

1) which distro are you using.... There are differing scripts to use to manage things.

2) You say that both 'seem to be working'
What are the results of ifconfig -a


3) In my slackware install I would use
/sbin/dhcpd eth0
This requires that /etc/HOSTNAME and /etc/dhcpd.conf be filled out with apropriate info ..HOSTNAME must be the assigned hostname from my isp provider, and the interface must be active prior to issuing this command.

Some system startup scripts attempt to dhcpd [ifx] BEFORE the insmod [ifx driver] .

This is generally what results in the ...delaying ifx initialization... errors.

Once the interface is up you can manually reissue the dhcpd [interface] to get the job done. If you use modules for your network cards, I suggest finding the dhcpd [interface] command in your startup scripts and inserting the appropriate modprobe [module names] line just before the dhcpd statement.
