Buck-Security – Escáner de seguridad para servidores Ubuntu y Debian
31 mar
Buck-Security es un escaner de seguridad para Debian y Ubuntu Linux. Le ayuda a fortalecer su sistema mediante la ejecución de algunos controles de seguridad importante. Por ejemplo, encuentra archivos y directorios con permisos de escritura para todo el mundo, los programas setuid y setgid, cuentas de superusuario, y paquetes de herramienta instalada de ataque. Asimismo, comprueba su umask y comprueba si el bit sticky esta activado para / tmp, entre otros puntos. Fue diseñado para servidores con Debian y Ubuntu, pero puede ser útil para cualquier sistema Linux.
Por ahora se aplican las siguientes pruebas:
- Búsqueda de archivos de worldwriteable
- Búsqueda de directorios worldwriteable
- Búsqueda de programas en donde se establece el bit setuid
- Búsqueda de programas en donde se establece el setgid
- Comprobar su umask
- Verificar si el sticky-bit está establecido para / tmp
- Búsqueda de superusuarios
- Comprobación de las políticas de firewall
- Comprobación de si es seguro sshd
- Creación de las sumas de comprobación y verificación de los programas del sistema.
- Buscando paquetes de herramientas de ataque.
Security Support for Debian GNU/Linux 4.0 to be terminated on February 15th
21 ene
One year after the release of Debian GNU/Linux 5.0 alias “lenny” and nearly three years after the release of Debian GNU/Linux 4.0 alias “etch” the security support for the old distribution (4.0 alias “etch”) is coming to an end next month. The Debian project is proud to be able to support its old distribution for such a long time and even for one year after a new version has been released.
The Debian project released Debian GNU/Linux 5.0 alias “lenny” on the 15th of February 2009. Users and Distributors have been given a one-year timeframe to upgrade their old installations to the current stable release. Hence, the security support for the old release of 4.0 is going to end in February 2010 as previously announced.
Previously announced security updates for the old release will continue to be available on security.debian.org.
Security Updates
The Debian Security Team provides security updates for the current distribution via <http://security.debian.org/>. Security updates for the old distribution are also provided for one year after the new distribution has been released or until the current distribution is superseded, whatever happens first.
Upgrading to Debian 5.0 alias “lenny”
Upgrades to Debian GNU/Linux 5.0 from the previous release, Debian GNU/Linux 4.0 alias “etch” are automatically handled by the aptitude package management tool for most configurations, and to a certain degree also by the apt-get package management tool. As always, Debian GNU/Linux systems can be upgraded painlessly, in place, without any forced downtime, but it is strongly recommended to read the release notes[1] for possible issues, and for detailed instructions on installing and upgrading.

Debian Gnome + Beryl “3D-Desktop”
2 jul
Debian GNU/Linux with Gnome Desktop running Beryl/AIGLX for 3d desktop effects. The video seems to run slow because the recording takes time and the framerate is not the best, but it runs very smooth.
You can get all themes, styles, icons etc. on gnome-look dot org. A lot of people ask for the dockbar, that is part of gDesklets.
