psad-2.0 release

psad is an iptables log analysis tool, and the psad-2.0 release is now
available:

    http://www.cipherdyne.org/psad/

This release will be discussed in my upcoming book "Linux Firewalls:
Attack Detection and Response": http://www.nostarch.com/firewalls.htm

Here are some of the highlights:

- Completely re-factored Snort rule matching capability. The Snort
  keywords ttl, id, seq, ack, window, icmp_id, icmp_seq, itype, icode,
  ipopts, and sameip are now supported directly through Netfilter log
  messages.

- Signature updates are now published on cipherdyne.org at the link
  below, and psad can download these signatures and put them in place
  within the filesystem with the new --sig-update command line argument.

- Added the ability to parse Netfilter logs and generate CSV formatted
  output. This is useful for visualizing Netfilter data with AfterGlow
  (http://afterglow.sourceforge.net). I have used the --CSV mode along
  with AfterGlow to graphically represent two of the Honeynet scan
  challenges (#30 and #34) that include Netfilter log data:

- Enhanced --Analyze output to include a listing of the top scanned
  ports, top signature matches, and top attackers. Here is an example:

- Many other enhancements and a few bugfixes. Here is the complete
  Changelog:
