[NTLUG:Discuss] Where's the best place to find answers about Linux?

[Bob Byron]

Hmm...  Sounds pretty good.  So this begs the question, can
the DHCP server be modified to execute iptables commands.
When someone logs into the DHCP server, I could automatically
execute an iptables command to allow only that MAC address.
And record the account used to create it.

Any comments?
