Re: [PLUG] hubs vs switches

["tpanzarella (harley)" <tpanzarella@acm.org>]

I think Jeff and Charles gave a thorough enough explaination of the 
functional differences between switches and hubs, so in a nutshell if 
your looking for performance and security (less exposure to packet 
sniffers) and you have the $$ a switch is the way to go.

One thing to note is that sometimes you want the features of hub over a 
switch.  One scenario where a hub might be better is if you wanted to 
log all packets to and from all hosts on a particular network segment 
(whether it be for security purposes, traffic logging, etc.) then the 
fact that a hub sends all traffic to all ports actually helps you.  You 
may want to put an IDS (Intrusion Detection System) such as Snort 
(http://www.snort.org) or even just run tcpdump on one of the machines 
on that network segment in order to capture all packets.  Just something 
to think about.
