Les slides de la présentation Bro : un NIDS pas comme les autres ? effectuée le 16 janvier 2007 dans le cadre de la réunion du groupe SUR (OSSIR), en collaboration avec Guillaume Arcas, sont disponibles au format PDF. Guillaume s'est chargé de faire la présentation, en prenant en compte les remarques très intéressantes de Franck Debieve, JP. Luiggi, et mes quelques remarques "cosmétiques". Je me suis chargé d'une démonstration de Bro 1.2.1 en me plaçant du point de vue d'un utilisateur qui connaît bien Unix (la plate-forme utilisée pour la démonstration est FreeBSD 6.2-PRERELEASE) et Snort et en essayant de clairement montrer que Bro, bien que très intéressant, reste encore incomplet du point de vue du "packaging" (configuration après installation, outils de gestion, ...) et au niveau de la documentation.

I am extremely proud and happy to announce that Lily-Aya, my second child/daughter, was born today at 11:40 AM CET. We didn't know her gender until the very last second! And it was a very nice and thrilling experience. We did the same thing for Noée-Neyla, her elder sister.

At 3.640Kg and 51cm, she is a nice baby. Expect some pictures to be published on this website pretty soon (read: until I get some rest and finish selecting the nicest ones). In the meantime, here is one.

Dans le cadre de mon travail, je crée et j'assure des formations autour de la sécurité et des réseaux informatiques. J'ai développé et je maintiens une formation sur le système d'exploitation libre OpenBSD, qui est maintenu par le projet éponyme; projet dont je fais partie en tant que traducteur en langue française et coordinateur principal de l'effort de traduction principalement.

Cette formation, que j'assure sur 4~5 jours habituellement en intra/inter-site couvre les sujets suivants:

• Vue d’ensemble
  
• Utilisation basique
  
• Aperçu des services disponibles
  
• Gestion des utilisateurs
  
• Gestion du réseau
  
• Ports et packages
  
• Système de fichiers
  
• Cron et gestion des logs
  
• Apache
  
• OpenSSH
  
• Packet Filter (PF)
  
• IPsec
  
• Maintenance et mise à jour
  

HAPSIS, mon employeur, a mis à disposition sous licence BSD les slides (PDF) d'une ancienne version de cette formation qui traite de la version 3.7 d'OpenBSD (aujourd'hui nous sommes en 4.0). Même si cette version date un peu, la plupart des informations y figurant restent pertinentes.

Je tiens à remercier Fabrice Frade d'avoir aussi rapidement accepté ma proposition de mettre à disposition ces slides.

When reading technical books, I use a variation of Richard Bejtlich's reading method. Please take the time to read his post before continuing with this one.

As far as I can tell, my method takes more time but it allows me to fully understand key material and "engrave" it on memory. I use a combination of post-it flags and plain, bright yellow highlighters and three reading passes:

• First pass of reading. Usually not very mentally taxing. Flag key ideas with the post-it flags. I usually do this during my daily commute (currently 1h15 * 2 approx) in the public transportation.
  
• Second pass of reading. Give more concentration juice to the flagged items. Highlight the parts that need to be fully understood and remembered. Take notes using a pencil when applicable. I usually do this either at home/work or while commuting.
  
• Third pass of reading. This is done sometimes later (after reading two/three other books for example). Skim over the text and reread the flagged/highlighted items. Take note using a text editor, wiki or something like that. I currently use VoodooPad. Enter important URLs in bookmarks (in a special "Analyze this" folder) and/or in del.icio.us (using a special tag). I usually do this at home/work.
  

[Jazz] Byzance, Nguyên Lê Duos (Nguyên Lê and Dhafer Youssef)
From the album Homescape.

Byzance is in my opinion the best song of 2006. Featuring two of my favorite artists, Guitar player Nguyên Lê and Oud player Dhafer Youssef, it has something very special that I can't define clearly in words, that "transcends" Music and gives me a ruch of amazing and very enjoyable emotions with its oriental, almost hypnotic, tone. The intertwinement of Oud and Guitar with oriental percussions is just perfect. The same goes for the excellent sound engineering, made in a home studio by Nguyên Lê. Dhafer Youssef's voice adds a very welcome touch to the song's core fabric. This is great Art. Thank you guys for this amazing piece of Music. I've listened to it about 30 times already and I am absolutely not tired of it.

I'd like to wish you a happy new year 2007, full of every good thing your heart may desire. Did you make any good resolutions? I made three. Here they are in no particular order:

• Give more love to the people I cherish and care for.
  
• Practice sport seriously and lose (many) extra kilos I've been carrying for too long.
  
• Get a driver license.
