Netfilter coreteam updates: Arturo Borrero enters emeritus status

Thanks to Arturo Borrero who has now become emeritus member of the coreteam.

Arturo Borrero joined the coreteam in 2017 after many years of contributions. In particular, Arturo was instrumental in driving the development of nftables in its early stages, after the code was merged into the Linux kernel in January 2014. Arturo also improved the conntrack-tools in many aspects as well.

Thank you Arturo for your contributions, your support and your invaluable feedback in these years!

Netfilter coreteam updates: Eric Leblond enters emeritus status

Thanks to Eric Leblond who has now become emeritus member of the coreteam.

Eric Leblond joined the coreteam in 2012 for his continuous contributions to the project since 2005 with a particular interest in the nfnetlink_* subsystems that allow to send packets and logs to user space, as well as to nftables. Eric Leblond was one of the main organizers of NFWS 2008 in Paris, France. Eric also maintained ulogd2 for many years, the userspace software for log management.

Thank you Eric for your contributions, your support and your invaluable feedback in these years!

Michael Rash's book on Linux Firewalls and IDS/IPS

Linux Firewalls is subtitled "Attack Detection and Response with iptables, psad, and fwsnort", and focuses heavily on what is possible from an intrusion detection and prevention standpoint within the context of iptables. There are many books that discuss firewall concepts and still other books that discuss intrusion detection, but none that really focus on the combination of the two technologies. Significant coverage in Linux Firewalls is devoted to seeing how attacks appear within iptables logs (with automated analysis performed by psad), and how the string match extension is used by fwsnort to detect application layer attacks. The book has two chapters on port knocking and Single Packet Authorization, and wraps up with a set of visualizations with Gnuplot and AfterGlow of iptables log data from the Honeynet project. The book is available for a substantial discount at:

http://www.nostarch.com/firewalls_mr.htm

An online site for the book is maintained here at:

Mailinglist problems

Due to yet unknown reasons, the netfilter and netfilter-devel lists have been deleted from lists.samba.org. While we are still investigating this problem, we have created new mailinglists at lists.netfilter.org. It is not clear whether there is a recent backup of the subscriber lists, so subscribing to the new lists is strongly recommended.
