NIC cards

NIC cards

[Majid Tahir]

hello all
i have just installed redhat 7.2 on a machine that needs to have 2 nic cards...however neither of the two nic cards have been "found".  How would i configure it so that the two cards are properly installed..also one other problem is that i dont know the name of one of the nic cards, therefore it is difficult to find the proper drivers

thanks for the help

Without knowing what the NICs are, it is difficult to give you a good answer.

If you really cannot determine the make and model, your only hope is brute 
force -- try modprobe'ing the various NIC modules one by one, until you get 
a hit. (I've actually had to do his once or twice myself, and it isn't as 
bad as it sounds, at least with pci-based NICs, since most of them seem to 
use tulip, rtl8139, or eepro100.)

It is possible that RH 7.2 uses a kernel with modules too old for some 
NICs. I've seen this sort of mismatch come and go with the tulip driver and 
Linksys NICs, for example.

Finally, are you sure that the NICs are good? Are they detected by the BIOS 
prior to Linux boot/init? Do they show up in /proc/interrupts? In the 
"lspci" listing?

If the NICs use isa slots ... did you configure them to use different IRQs 
and IObase values? (If you put only one in the system, is it detected and 
initialized properly?)

If none of this helps, please post again with the following additional info:

1. Are the cards isa or pci?

2. What is the make and model of the one NIC you *do* know?

3. What can you figure out about the other one?

4. What kernel version are you using?

And answer for us the various questions I suggested you try to answer for 
yourself.

Are they PCI or ISA cards.???

If they are PCI then the command 'lspci' or cat /proc/pci will show there 
make and type.
(I cant imagen them being PCI cards if the install did not find them).

If they are ISA cards and you have a windows machine handy then you may be 
able to gain information on thier type/make via windows.

When you can tell us what the cards are, there make and type then we can help 
you more.

Re: NIC cards

[Haines Brown]

Majid,

I've suffered from the multiple NIC problem, and so stalted way the
following notes. But keep in mind I've no expertise myself.

It is especially tricky to configure more than one network of the same
type, such as getting two NICS to co-exist. Sometimes the machine
determines which NIC is eth0 and eth1, so that when the drivers are in
the kernel or when two cards share a driver, whichever the machine
sees first is labeled eth0. Therefore you may have to adapt your
configuration to suit the machine.

1. If adapters don't coexist, you can try just swapping eth0 and eth1.  

2. Use NICs that use the same driver compiled into the
kernel. Sometimes this works automatically, but sometimes you must
include proper kernel options in LILO configuration so that the kernel
looks for two NICs (add line: append = "ether=0,0,eth1" to tell Linux
to look for a second card). This probably required if NICs are ISA
cards.

3. NICs that use the same driver which is compiled as a module. You can
usually get good results by adding lines in /etc/conf.modules to tell
the system you have two NICs. Add one alias line per NIC, as in:

	alias eth0 tulip
	alias eth1 tulip

This tells the system to use the tulip driver for both cards.
	
4. Different drivers compiled into the kernel. With PCI cards, which
often work automatically, see (2) above.

5. Two NICs using different drivers compiled as modules. This works
like (3) above except that the lines refer to different modules.

Hope this helps, but others will surely chim in with corrections and
other suggestions.

I'd suggest that you open the machine up and look at the cards.
