    Leaving aside the inherent sketchiness of having a "company" and prosecuting people to "life-time prison," I'm going to let you in on a little secret. If you type in "MAC address" into the little box next to the word "search" above, you'll find that this subject has been hashed and re-hashed many a time already. For instance:

    In the future, kindly do a minute of searching before doing a minute of posting.

    perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'

    I assume from your statement, you are using static IP addresses. A better solution is to use DHCP to assign the addresses. Getting the MAC address and/or controlling who has access to Internet is then pretty simple. If you're using Linux for the DHCP server, the MAC address and corresponding IP address can easily be obtained from dhcpd.leases.

    I suspect there is a similar way under Win2000 to get the MAC addresses and corresponding IP's, but I have no first hand knowledge.

    Depending on your firewall / proxy server, I suspect the same information could be obtained from the logs there.

    Why not just configure Squid to use proxy_auth so the clients need to have a valid username and password?
