I have just set up a wonderful new transparent bridge/firewall and am looking for suggestions on good additions to my networking toolbelt. Running FreeBSD on a brnad new little server with a 40GB HDD, 256MB Ram for a dozen web/mail/ftp servers.
I am pretty impressed with one particular thing I found - iftop - (for the first time ever I see what is happening on the network) and realized there is probably a whole world opening up to me in the FreeBSD CLI world.
What other "critical networking tools" do you guys swear by?

2) Snort (and related additions?) / Hogwash
If you can give me a "programs you can't live without" list for managing a network, that would be swell. Think bandwidth monitoring, bandwith limiting, intrusion detection, etc.
Any suggestions are welcome...
