NIC cards setup


Hello,
Ok I'm very new at using Linux and need some help!

I want to setup an old pentium as a firewall for my home use. I'm running into some problems though configuring the network cards.

For some reason it will only detect one of the cards but I still can't connect to the internet using it.

Where should I start? Or what do you guys need from me for more information on how to fix this. Remeber I'm really new with Linux, I'm running Redhat 7.0.

3com make lots of cards... 3c509, 3c90x, etc... ISA or PCI. Some of the older cards have to have the IRQ and address changed by hand. Depending on the card you may have to specify the cards parameters in the lilo.conf file.

Take a look here for more info:

Ok I have a 3Com 3C900B-TPO and a SMC 1244TX-50 ( my mistake I thought they were both 3com) Both are PCI. But I do have a very old ISA 3Com 3C509B laying around. How do I edit the lilo.conf? what shoudl I be looking for?

THanks for your help so far.

Post the section of your kernel boot up sequence where the nic cards are configured.


Jul 14 21:28:35 kernel: 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html

It would also help to look at /proc/ioports:

0300-030f : 3c509
fc00-fc7f : 3Com Corporation 3c905B 100BaseTX [Cyclone]
fc00-fc7f : 00:0e.0
fce0-fcff : Intel Corp. 82557/8/9 [Ethernet Pro 100]


and /proc/interrupts:

Code:
           CPU0
  0:   63535527          XT-PIC  timer
  1:          2          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  5:     174062          XT-PIC  eth1
 10:     343630          XT-PIC  eth0
 14:     174320          XT-PIC  ide0
 15:          4          XT-PIC  ide1
I have found the 509 cards to work very well. It is only 10Mb but that should be fine if you are talking to a 10Mb DSL or cable modem.
