[CLUE-Tech] Small network security distro recommendations?

[skipworthy at realivetech.com]

Hey-

I was on my way to sourcefourge to look for this, but I thought I'd toss it
out to you guys for your thoughts...

I want to build a firewall/router box, that should also  be able to do
things like logging and intrusion detection,  email alerts and so on, and
some other white-hat stuff. I'd like it to be lightweight, but be able to
optionally run a simple xserver/GUI and a fairly complete set of tools.

I plan on using a P233, with 6G or so of harddrive space and less than 128M
of RAM

I know this leaves alot of room- it shouldn't be hard to find somehting.
What I want to know is: what have you guys used for this kind of setup, or
heard of, that you are impressed with/exciited about?

Glen
