We’ve all heard about Windows Rootkits, but open source operating systems aren’t immune either. In this edition of Federico Biancuzzi’s periodic BSD Interview series, he talks to Joseph Kong, author of Designing BSD Rootkits about creating and defending against rootkits.
OpenBSD 4.1: Puffy Strikes Again
OpenBSD 4.1 has recently been released. It includes improvements to spam fighting, SMP, porting to new platforms, and much more. As usual, Federico Biancuzzi has sought out some of the most influential OpenBSD developers for a discussion of what you’ll find in 4.1
Making NetBSD Multiboot-Compatible
The i386 boot process is as crufty as you’d expect from decades of stagnation. Booting your OS could be much easier–that’s why the GRUB hackers developed The Multiboot Specification. Julio M. Merino Vidal explains why Multiboot exists, what it can do for you, and how he modified the NetBSD kernel to work with it.
Inside PC-BSD 1.3
iXsystems’ recent acquisition of PC-BSD hasn’t slowed the development of the desktop-capable FreeBSD distribution. Version 1.3 is out and available. Dru Lavigne talks with PC-BSD developers about the new release and their plans to continue to make an effective, efficient, and usable free desktop operating systems.
Greylisting with PF
Greylisting–delaying mail delivery briefly per the SMTP RFCs–is an effective way to reduce the amount of incoming spam. While many greylisting solutions require customization of your SMTP server, OpenBSD’s PF can do it too. Dan Langille shows how to use the powerful packet filter to identify and pass legitimate mail, delay and divert potential spammers, and throw in some OS fingerprinting to ward off certain zombie clients.

The Release Engineering Team is happy to announce the availability of FreeBSD 4.11-RELEASE, the latest release of the FreeBSD Legacy development branch. Since FreeBSD 4.10-RELEASE in May 2004 we have made conservative updates to a number of software programs in the base system, dealt with known security issues, and made many bugfixes.
For a complete list of new features, known problems, and late-breaking news, please see the release notes and errata list.
FreeBSD 4.11 will become the first “Errata Branch”. In addition to Security fixes other well-tested fixes to basic functionality will be committed to the RELENG_4_11 branch after the release. Both Security Advisories and Errata Notices are announced on the freebsd-announce@freebsd.org mailing list.
This is expected to be the last release from the RELENG_4 branch. Most of the Developers are now focused on the RELENG_5 branch, or on the cutting edge development in HEAD.[/quote]
