Why don't the numbers support the experience? We have 1Mb/s download and
128K upload (telewest cable). In theory even between us we weren't using
all the bandwidth.
If I put a FreeBSD NAT/router box between the cable modem and the LAN
what console based tools should I put on it to examine what's happening?
You want:
snort for packet sniffing and analysis
nmap for scanning your network to see if someone is running wierd apps.
You may want to configure your firewall with pf and queuing so limewire
etc doesn't eat it all up. With pf, you can also monitor the state
table, and you can also log suspicious traffic or traffic that causes
problems. You need to use tcpdump to read the logfile.
IIRC, ethereal is a server/client program where the server runs on the
trusted host where you want to monitor the traffic. It is good for
getting the big picture of what is going on. Also, take a look at
nagios. I have to say that I haven't used ethereal or nagios at all.
