[TCLUG:1315] Internet server (was: Why Linux?)





Cool...thanks guys. I might try the port-blocking, but then again I've
been meaning to set up a local DNS too...

If I point the Win95 box to the local DNS, but link is down and my DNS
doesn't have the requested record in it's cache, will that cause the
link to come up?

Block udp and tcp on ports 137, 138, and 139. This what netbios crap
talks on. Or nbt for that matter. Filter these ports and your keep 
your link stay down.
