In follow up to my previous post, I up together an outline for iptables and posted a
classroom session here:
https://fedoraproject.org/wiki/Classroom
This gives about 2 weeks for promotion of the event.
The handout is long, and I am planning to cover the basics and filtering only in the irc
session, NAT or other questions as time allows, but the handout is a (bit) more
comprehensive.
I will look at suggestions for additional classroom sessions , selinux has been mentioned
and I may do that next.
