But the DHCP assigned address doesn't have to be randomly assigned from "the free pool." I like having each machine be assigned the same address each time. If nothing else, when something shows up in the firewall logs it's trivial to figure out which machine was the problem child. And if something does show up that was assigned from the free pool.. it's always turned out to be something new my wife didn't mention. <.. snip ..> > If you are interested in some good reading on Unix & Linux networking, > then pick up a copy of W.

I've got it, but I preferred Internetworking with TCP/IP by Douglas Comer - a three volume set; volume 1 was my reference manual for ages. Regards, Lee
