The OpenBSD team traditionally makes available a new song with each new release of its software. The songs, though often of dubious lyrical quality, typically embody the current thinking of the development team, in particular that of team leader Theo de Raadt. In the past the songs have railed against proprietary software developers and corporates and the challenges they throw in the way of free software. This time, however, the target is the Free Software Foundation’s Richard Stallman.

The Linux kernel is a funny thing. A new kernel should mean increased functionality, but for me and my old-and-getting-older machines, I only seem to lose functionality with upgraded kernels. I hadn't updated Debian Lenny in a while on the $0 Laptop (the Gateway Solo 1450), and when I did it today, I noticed a new kernel being added to the system: 2.6.24-1. I didn't think about the new kernel when I next booted into Lenny, but when I did, I soon discovered that my sound card didn't work anymore. I looked at all the settings, tweaked a bit here and there, but still nothing.

As usual, OpenBSD 4.2 offers a large collection of intelligent changes to an already great operating environment.OpenBSD overviewThis section is for people who are not yet familiar with the OpenBSD operating system. Those who are may want to skip ahead to the next section on the new features in version 4.1The BSDs in general have a common reputation for high code quality and poor hardware support. In OpenBSD's case, the code is definitely high quality. Nothing in the default installation is half-implemented, or committed on an experimental basis. If full functionality is not yet possible for hardware drivers, basic functionality is achieved and thoroughly tested; this forms the basis for further driver development. Everything you get in the release is production-ready, secure by default (m

The OpenBSD team is pleased to announce the release of OpenBSD 4.2.

Como es costumbre cada seis meses, Theo de Raadt nos trae una nueva versión del sistema operativo de amores y odios, OpenBSD. En esta ocasión presenta importantes mejoras en soporte para SATA y los nuevos chipsets, nuevas herramientas de trabajo de escritorio y red. El interesante port de Xorg 7.2 bautizado como Xenocara y más. El informe completo. Por otro lado no es raro ver KDE actualizado en OpenBSD gracias al enfoque de este escritorio en ambientes multiplataforma (claro, gracias a Qt), sin embargo veo con agradable sorpresa que ya cuenta con las librerías GTK 2.10 lo que le abre paso a Xfce 4.4 y a Gnome 2.18. Ustedes pensaran que están un poco atrasados pero dada la relación entre GTK y Gnome y su enfoque principal en GNU/Linux las cosas son un poco más difíciles de portar. URL’s de interés: Informe. Xenocara. OpenBSD.

Packet Filter (from here on referred to as PF) is OpenBSD’s system for filtering TCP/IP traffic and doing Network Address Translation. PF is also capable of normalizing and conditioning TCP/IP traffic and providing bandwidth control and packet prioritization. PF has been a part of the GENERIC OpenBSD kernel since OpenBSD 3.0. Previous OpenBSD releases used a different firewall/NAT package which is no longer supported. (more…)
