Dear Sir:

I installed the linux version 3 to my laptop pc and do a ifconfig, there is only the lo device shows up, no eth0 device. i need to setup the networking, security and firewall for this linux system. if there is no eth0 device, can i do all of these? what does the eth0 device do?

thanks and regards!
David

Hi , eth0 means your ethernet card. For networking this should be needed,if u dont have inbuilt nic, purchase pcmcia nic card and installed in to your machine. It will work.

dear sir:

the linux i used is version 3 redhat enterprise ws. could it be possible that the version of linux i installed cannot find the eth0 device on the pc? how can i physically identify the eth0 device on my laptop?

thanks!
david

Try "lspci" and look for the card. Once you have found it, you can figure out the module it needs, and "modprobe" it. You can also add it to /etc/modules.conf for autoloading at boot.

If you have documentation on the laptop, you can always read that and identify the ethernet card.

its like a telephone jack but bigger in size,normally its in your backside of the laptop (two connected monitor symbol will be there.)

dear sir:

the linux i'm using is version 3 enterprise ws, a pretty new version of linux. the laptop i'm using is Gateway solo, 33mhz. could it be possible that the new version linux doesn't support my old laptop pc?

thanks!

wow.. It's definitely not going to have an onboard ethernet card... you need to go get yourself a PCMCIA (PC Card) LAN Card for the notebook.. then you will have an eth0 entry... also.. since you will need to purchase one... make sure it is a card well supported by linux...

Good Luck..

dear sir:

it looks like that there is not the module for eth0 in the linux system. how can i know which module should be provided in order to make the eth0 available for the linux system?

thanks!

are u trying to network to a desktop computer... u r going to need network cards in each one and also a cable to connect them both....u can do this directly with a cross over cable from pc to pc or u can use a hub or router
Mainly u r going to have to make sure u have the network cards in each before you can go any further. Check in the back of your laptop and other pc that u have a slot (similar to where u would plug in your modem) there is usually a small light (which will light up green when u plug in your cable)
The next questions are which type of os are u trying to network to? and by which method?
