Short text going over several tools that can help a system administrator work on incident prevention, network monitoring and intrusion detection in Linux. I presented this talk in UNAM's Departamento de Seguridad en Cómputo internal admin-unam seminar, in June 2005. It was also published in the August 2005 issue of PC Magazine en español.

This talk was prepared for the National Free Software Conference CONSOL 2003 and for Computer Security DGSCA/UNAM 2003 Conference. I analize the main ideas that were used for designing Multics, which of those ideas were adapted for the Unix model, which main shortcomings the traditional Unix model has, and what ideas have evolved to make Unix better.

I gave this talk at the GNU/Linux 2001 conference in Jalapa, Veracruz, in September 2001. In this article I show different characteristics and security reccomendations using free operating systems and tools.

Once again, I was invited to the seminar, with Computer Security Department of UNAM, this time in April 2001. The topic this time: Security guidelines in a Linux installation. How you can make a newly made Linux installation a difficult target for an attacker.
This same material, although updated and enhanced, was also presented as a tutorial at Congreso de Seguridad en Cómputo 2001, also organized (of course) by DSC, UNAM.

Beyond what the Debian policy gives us, a highly coherent system in which everything is in its place and works as it should (for what we the system administrators are really thankful for), we can find a great amount of tools for easing the homogeneity in the administration both in the planning of its package management system as in many packages we have at our disposition. We will go through this, as well as the process of creating .deb packages, beyond the basic instructions. This talk was originally prepared for CICOL, June 2006

Resumen: 
Más allá de lo que ya nos dan las políticas de Debian, un sistema altamente coherente en el cual todo está en su sitio (lo cual bendecimos los administradores de sistemas), tanto en la planeación de su sistema de paquetes como en varios paquetes que tenemos a nuestra disposición encontraremos una gran cantidad de herramientas para facilitar la homogeneidad en la administración de sistemas. Revisamos algunas de ellas, así como el proceso de creación de paquetes .deb, más allá de las instrucciones básicas. Preparado originalmente para el CICOL, junio 2006

What social characteristics can define the Free Software developers? Are we really a homogeneous group? Which problems can appear when facing a global project? How can we avoid them? I analize mainly the Debian project, comparing a bit with the OpenBSD and Ximian/Gnome projects.
This talk was prepared for the 2003 GULEV conference.
It is available as:

Resumen: 
¿Qué características sociales definen a los desarrolladores de Software Libre? ¿Somos realmente un grupo homogéneo? ¿Qué problemas principales pueden darse al enfrentarnos con un proyecto mundial? ¿Cómo los evitamos? Analizo principalmente al proyecto Debian, comparando un poco con los proyectos OpenBSD y Ximian/Gnome.
Esta plática fue presentada en la edición 2003 del Congreso GULEV.

A system I wrote while working for FES Iztacala. It helps a network administrator on his tough job relating MAC and IP addresses, generating configurations for the DHCP server and for ARP.

In this presentation, I explain what is Debian GNU/Linux, and what makes it be what it is. I presented it for Departamento de Seguridad en Cómputo's GASU seminar, May 2002.

A presentation prepared for Días de Software Libre, confernce organized by Melix at CUCEI (Guadalajara, May 2002). Here I talk about what are package management systems, why are they needed in modern operating systems, the main characteristics
for the main package management systems, and briefly explain how to create .deb (Debian) packages.

Tutorial (not completely finished) I gave together with Rodrigo Galladro at Congreso Nacional de Software Libre (CONSOL 2002). There are many aspects in this tutorial that are just outlined, but I hope you find it useful.
