Webservers and such aside, I was discussing the use of a workstation that connects to the Internet, and the chain of access via the machine's ethernet adapter or Network Interface Card (NIC), which is often plugged on the other end (after a few hundred feet of cat-5 cabling that snakes behind the walls and up in the ceiling) to a switch or hub that talks to a router.

Perhaps this is what I should've asked first :-) Hubs I believe by default offer bandwidth to connecting workstations on a "promiscuous" basis, that is, any port can kind of turn around and instead of saying "hm, is this packet for me, no.. okay is this one for me? no... etc" say "hm, is this packet for me, no... well it won't hurt to look IN the packet since I have it in my possession..." Switches use a dedicated bandwidth paradigm. Port #2 cannot sniff what's going on on say, Port #8 (by default), and promiscuously declare "ok all you packets, please step forward if you contain either [Uu]sername and/or [Pp]assword in your backpacks. > Appreciatively, > Courtney I just love the name Courtney. I just had to say that. Actually, all girlish names ending in an eee sound are loved by me; Ashley, Chelsey, Britney, Kelcey, I could go on forever but will spare you this once. :) -- Peter Leftwich President & Founder Video2Video Services Box 13692, La Jolla, CA, 92039 USA +1-413-403-9555 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
