Just Curious on how you would go about altering your MAC address. I have seen it done with dos real-mode ipx drivers by putting an entry into the 'net.cfg' file.....

Is this possible in linux?

I'm aware that the MAC address is burned into your NIC. When you are using Novell's real-mode ODI drivers for DOS based machines you can change your MAC address By typing in your NET.CFG something like this...

Link Driver smc8000
    Node Address 10ba5e2

This will make your Make Address  02:00:01:0b:a5:e2
The '02' in the first octect is because we locally assigned the MAC address...

I'm merely just looking for a way to alter the MAC address
using software under linux...

When you mean Ethernet-Adress(00-00-c0-33-81-a4) by Mac-Adresse then I have an answer:

You cannot, as far as I know, change the Ethernet-Adresse of your Network-card. Every Eth-Card has its own worldwide unique Eth-Adr which is hardcoded by the manufactur.

I know you can't physically change your MAC address on your NIC short of an EPROM burner ( only on the older cards ).. I'm trying to find out a way to do it using software at run-time, like Novell's real-mode drivers...

You can change the extention but you cannot delete it. You could change 'ice' to 'icex'. May be this does the trick.
