DESCRIPTION:The OpenBSD Packet Filter (PF) is at the core of the network ma
 nagement toolset available to professionals working with the BSD family of
  operating systems.\n\nUnderstanding the networking toolset is essential t
 o building and maintaining a functional envirionment. The present session 
 will both teach principles and provide opportunity for hands-on operation 
 of the extensive network tools available on OpenBSD and sister operating s
 ystems in a lab environment. Participants will be performing practical exc
 ercises in their choice of OpenBSD and FreeBSD environments. Basic to inte
 rmediate understanding of TCP/IP networking and basic Unix command line sk
 ills are expected and required for this session.\n\nTopics covered include
 \n\nThe basics of and network design and taking it a bit further\n\nBuildi
 ng rulesets\n\nKeeping your configurations readable and maintainable\n\nSe
 eing what your traffic is really about with your friend tcpdump(8)\n\nFilt
 ering\, diversion\, redirection\, Network Address Translation\n\nHandling 
 services that require proxying (ftp-proxy and others)\n\nAddress tables an
 d daemons that interact with your setup through them\n\nThe whys and hows 
 of network segmentation\, DMZs and other separation techniques\n\nTackling
  noisy attacks and other pattern recognition and learning tricks\n\nAnnoyi
 ng spammers with spamd\n\nBasics of and not-so basic traffic shaping\n\nMo
 nitoring your traffic\n\nResilience\, High Availability with CARP and pfsy
 nc\n\nTroubleshooting: Discovering and correcting errors and faults\n\nYou
 r network and its interactions with the Internet at large\n\nCommon mistak
 es in internetworking and peering\n\nKeeping the old IPv4 world in touch w
 ith the new of IPv6\n\nThe tutorial is lab centered and fast paced. Time a
 llowing and to the extent necessary\, we will cover recent developments in
  the networking tools and variations between the implementations in the Op
 enBSD and FreeBSD operating systems.\n\nParticipants should bring a laptop
  for the hands on labs part and for note taking. The format of the session
  will be compact lectures interspersed with hands-on lab excercises based 
 directly on the theory covered in the lecture parts.\n\nThis session is an
  evolutionary successor to previous sessions. Slides for the most recent v
 ersion of the PF tutorial session are up at https://nxdomain.no/~peter/pf_
 fullday.pdf\, to be updated with the present version when the session open
