Hmm, the drawbacks of such a licensing system are numerous under
Linux, and are virtually unenforcable. Simply set the eth0 MAC
address to be whatever you like. It shouldn't be too hard, and
it will also ensure that your expensive software will continue
to be available if you should ever have to swap the motherboard
because of hardware problems, or an upgrade.

Looking at ifconfig(8), it looks like the following will work:

ifconfig eth0 hw ether 01:23:45:67:89:ab

I just tested this and it appears to work on my card (xirc2ps_cs)
after I unconfigured the interface (couldn't do it while up),
and I checked on a remote host that it also appears with this
MAC to arp. This is ifconfig 1.39 (1999-03-18) and kernel 2.4.13.


Note that I'm not advocating stealing the software (or using more
than the number of licensed copies), just in making the situation
much more convinient for you.


This is, once again, is a situation where describing the real
goal, as opposed to the immediate problem, is much more likely to
get you a usable solution.

Cheers, Andreas
