working with 2 similar network cards

kizersouzay · 07-17-2006, 12:16 AM

By chance i have 2 network cards that are of similar type.One is built-in in the motherboard.While other is in the pci slot.Now i am having following problems.
1-I can't distinguish them in the OS i-e when is list them by using "lspci", both listed but i cant be sure which one in the list is refering to which physical card.
2-Kernel is installing the driver for only one card(as expected as it is mentioned in the Network administrators guide NAG).Now the problem is that some parameters are required to probe it by passing certain parameters(irq,base address,I/O address)where can i ger this information for my cards.I have intel eepro

Hi,

First, you state there are two nics in the machine. One is in the pci slot. Which slot? What card?

The on board is a intel, which chipset? What is the motherboard?

Machine manufacture?

Post the output from a terminal/cli (un-edited);

Code:

#dmesg |grep eth     #show the eth devices on boot
#lspci -vv          #you should be able to see irq and nic info
#lsmod              #modules
#ifconfig -a        #recognized

I think you meant:

Code:

dmesg |grep eth

Hi,

Yes, just these big hands on a little laptop kybd.

ok,
that system was not mine but that of my friend
But on my system again there are two cards.Both in the pci slots.
here is the out put from the terminalKernel command line:

bash-3.00# dmesg | grep eth
Kernel command line: BOOT_IMAGE=Linux ro root=347 ether=0,0,eth0
e100: eth0: Intel(R) PRO/100 Network Connection

I think the kernel is probing the driver for only one.How to get the other one working?

archtoad6 · 07-20-2006, 07:20 AM

I think your Q about your own system is very different from your friend's. To me, the output of ifconfig -a clearly shows that the kernel has found both cards, eth1 just hasn't been brought up yet.

With the card connected to a DHCP server, try each of the following (only one will work):

Code:

pump     eth1
dhcpcd   eth1
dhclient eth1

As for your friend's box, we probably need to see the actual output of the suggested commands. Try ifconfig -a 1st. If you see both NIC's, then he has the same problem you do & the other commands probably aren't necessary. If you do post the output from lspci -vv, consider removing the sections not related to the NIC's.

how can it be possible that both cards are "up"
when system boots.What settings are required

archtoad6 · 07-27-2006, 12:52 PM

What makes you think that a GNU/Linux box can't have 2 cards up at once?

How do you think a dedicated firewall appliance (like my SmoothWall Express) works?

As for the "required settings", the short answer is to find out where your system brings up the 1st card & add similar lines appropriate to the 2nd card. This will be somewhere in the init scripts. I can't be more helpful because I switched from RH8 to Debian (& later to MEPIS) about 3 years ago.

Hi,

The eth0 and eth1 devices were detected! You just have eth0 with a IP assignment.
Therefore both eth devices are not up! Just eth0.

You could look at this tutorial to get some guidelines.

If you would like to assign a IP to eth1 statically then as root from cli;

Code:

#ifconfig eth1 192.168.1.12       #incremented eth0 IP
#ifconfig -a                      #seee the assignment
#route -n                         #check routing table

You could edit the config file;

Code:

#vi /etc/sysconfig/network-scripts/ifcfg-eth0  #make changes and save
#vi /etc/sysconfig/network-scripts/ifcfg-eth1  #make changes and save

Or you could use the tui;

Code:

#/usr/sbin/system-config-network-tui

Of course you will have to init your network if you make changes. Once you make changes to the config files the assignments will be made.

This is all covered in the tutorial

A little google does wonders!

BTW, I agree that you should only post relevant information. Not the whole output of a command unless the output contains information about the problem at hand.

The command;

Code:

#lspci -vv                 #very verbose

A lot of what you posted for the lspci was not relevant to the problem.

archtoad6 · 07-27-2006, 05:09 PM

Nice answer, gwsandvik.

And thanks for reinforcing my suggestion about leaving out extraneous info. I almost didn't bother w/ this one because of it.
