New Network Card

[jrbush82]

Hello all, I've installed a second Linksys Network card into my system. When I type ifconfig, there is only the original eth0 card that I had to begin with. How do I go about configuring and installing the software for the new network card in Linux?

Thanks,
Jason Bush

The software is already installed... "/ifconfig eth1 up" All you need to do is configure.

How do you want it configured?

Well... as you can see:

root@jason:/home/jason# ifconfig eth1 up
eth1: unknown interface: No such device

It didn't work. Any other ideas?

Fire up linuxconf, choose Config->Networking->Hostname and IP Network Devices->Adaptor 2. In the Net Device field, select eth1. Choose the correct module from the Kernel Module drop-down list. Enter the apppropriate information (host/domain name,IP, netmask, etc.) in the remaining fields and enable the device. If you're using DHCP, most of this will be automatically obtained, of course. Since you already have one card working, your DNS and Gateway info should already be in place, yes?

If you still get the error, here are some thoughts:

as root:
- Type dmesg|less to review your bootup messages, and use the page up/down keys to navigate through the file. Look for lines beginning with "eth0" and "eth1" and note any relavent messages/errors.

- Type cat /proc/pci. Are both Ethernet controllers identified, or just the controller on eth0?

- Type cat /proc/interrupts. Do you see both eth0 and eth1? IRQs can usually be shared, but note any conflicts just to be on the safe side.

- Type lsmod to list the currently loaded modules. Is your NIC's module listed?

- Does /etc/modules.conf have an "alias" line for both NICs?

I do not have linuxconf. I am running Slackware 8. Should I download and install that? The only thing that found the card was /proc/pci and when I was in KDE I went to a device manager type deal, and it said that it was an ethernet card, but there was no drivers or anything for it.

I haven't used Slack yet, so I don't know what it uses for a configuration utility. If it doesn't have linuxconf, I'm sure it has something similar. You said you already have a net card; how did you set that one up? It is working correctly, right?

Did you try "lsmod"? If not, do so now, and post the output. Check your /etc/modules.conf file (/etc/conf.modules in some distros). There should be an alias for both devices, even if the cards both use the same module:alias eth0 name_of_module_used_by_eth0
alias eth1 name_of_module_used_by_eth1

Here is the result of lsmod:

The other card was in during installation, and it was configured perfectly and working perfectly the first time.

Do you know what module the Linksys uses and do you have that module on your system? If you do, then try 'modprobe module_name'.

If it loads, then next would be 'ifconfig eth1 up' as the others suggested.

de4x5 39440 1 *** ETH0O.K., lsmod is showing that the de4x5 module is loaded, and being used by eth0 (although I'm not sure about those three asterisks). No mention of eth1 though, so:

Do as mdwatts suggests. If that doesn't work, please give the exact model of both NICs, and what modules you believe they should be using. Also, give us the result of my previous suggestions:

Yuo might also have a resource conflict with the second card. Turn off Plug-N-Play OS support in your BIOS if you haven't already.
