A message to the [leaf-user] mailing list (Sun, 29 Jun 2008 04:52:58 -0700) asked whether it would be practical to submit firewall logs to DShield.org
In the follow-up messages we concluded that it would not be practical with Bering-uClibc 3.x, mainly because there was no Perl interpreter available.
With Bering-uClibc 4.x everyone running Shorewall must also have Perl available, so presumably this is a possibility now?
The DShield "framework" client details are at http://www.dshield.org/framework.html and while the "iptables" entry refers to Linux 2.4x I don't think iptables has changed fundamentally for Linux 2.6x
