Subject: [UKUUG-Announce] UKUUG & O'Reilly - PF - the OpenBSD packet filter    - Tutorial
Building the network you need with PF, the OpenBSD packet filter
22nd September 2011
Imperial Hotel, Russell Square, London WC1B 5BB
Description: This one day session is aimed at experienced or aspiring network 
administrators who want to expand their knowledge of PF, the OpenBSD packet 
filter, and related tools. A basic knowledge of Unix and TCP/IP network 
configuration is expected and required. Topics covered include
* Configuration on OpenBSD, FreeBSD and NetBSD
* PF ruleset basics and rule interactions: block, pass, match
* Writing maintainable rulesets
* Address families: IPv4 NAT vs IPv6
* Redirections and services with odd dependencies (ftp-proxy, spamd)
* Adaptive rulesets (state tracking tricks)
* ALTQ traffic shaping
* Per user filtering with authpf 
* High availability with CARP, relayd 
* Wireless vs wired networks
* Filtering bridges
* Logging and monitoring - pflog, pflow and others
* Testing, debugging, and optimizing your configuration
The session will provide updates on the new PF syntax and features introduced 
in OpenBSD 4.7 (with samples presented in the old and new syntax where 
appropriate), with newer updates and reviews of relevant new features in the 
upcoming OpenBSD 5.0 release.
The tutorial is loosely based on Hansteen's book, The Book of PF (No Starch 
Press, second edition November 2010).
Tutor: Peter N. M. Hansteen is a consultant, writer and sysadmin from Bergen, 
Norway. A long time freenix advocate and during recent years a frequent 
lecturer and tutor with emphasis on OpenBSD and FreeBSD, author of several 
articles and The Book of PF (No Starch Press 2007, 2nd edition November 2010). 
He writes a frequently slashdotted blog at

I never really understood how there could be things that would
drive you insane just because you knew them until I ran into Windows.
