ethernet lost

[BadFishBrewer]

I am running red hat 6.1 (cartman)
as a server and i just installed a nic card.
When i booted up the server saw the nic and installed it.
Great!
then i used a win2K computer and telneted into my
Linux server and monitored it from the server.
Awsome!
i then used the command 'ifconfg'
and the result where
eth0 and the ethernet info
lo and the local info.

Ok... so i was messing around and got stuck so i rebooted the
server and now when it reboots it only logs in local all the ethernet info is gone.

what did i do wrong???
:(

you need to provide more information:

1. what kind of card

2. Does /etc/modules.conf have an "alias" line for eth0? If so, which module is listed there and skip to 3 d & e (and substitute the name of the module you found in /etc/modules.conf for the text "YOUR MODULE NAME HERE."

3. Please provide the output of the following commands:

a. ifconfig -a (this should list all your network interfaces whether they are up or down)


b. lspci |less (to see if your card has been assigned a resource)

c. lsmod (to see if your driver shows up in the list of loaded modules)

d. locate YOUR MODULE NAME HERE

e. modprobe YOUR MODULE NAME HERE

To add to rioguia's suggestions:

Do you get any error messages concerning the NIC during bootup? For instance, something similar to the following:

"Bringing up interface eth0 [FAILED]"

If so, post the exact text of the error. If not, you're card might just not configured to come up at boot. Log in as root, go to a command prompt and:

1. Try to bring it up manually by typing:

ifup eth0

Run ifconfig (without the "-a" option) and see if it came up.


2. Look in your /etc/sysconfig/network-scripts/ifcfg-eth0 file. You should find the following line:

ONBOOT="yes"

If ONBOOT is not set to "yes", open the file in a text editor (make a backup of the file first!) and change it to "yes". Reboot the computer and see what happpens.
