The title of the presentation I'll be giving is:
"Linux firewalls for fun and profit (The short course)"
It's as quick-yet-complete an introduction as I can come up with to get
people familiar, not only with setting up a Linux firewall, but with
firewall and security concepts in general. It's probably going to be a
bit more "intense" than just a presentation - more of a mini-tutorial
kind of thing. I imagine it'll be just over an hour or so, excepting
Q&A.
Don't worry too much if you don't get something immediately - I'll post
all the slides on the web so you can go back over and look at everything
at your leisure.
And bring your pads and pencils, there WILL be a test afterwards.
