NIC cards setup

Bink · 07-25-2003, 03:05 PM

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.

What kind of cards are they?

They are 3com cards.

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.

I'm also getting this error when I boot up this system. Cannot look up internet address H24-67-75-90. And i goes on to say that gnome will not work correctly. any ideas of how to fix this?

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

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

and /proc/interrupts:

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.
