Je suis Administrateur systèmes (multi-os) et je travaille sur Rennes, je m'occupe de ce site quand j'en ai le temps et surtout le courage, c'est à dire pas souvent en fait ...

J'espère réunir ici des documentations ou mes développements en espérant que cela vous soit utile.

Squid - DansGuardian

DansGuardian: 2.12.0.5
Large System Performance


- Fix "Dammit Jim, I'm a filtering proxy, not a rabbit." Support large MaxChildren value - by Frederic Bourgeois.
This new option is used to define the number of file descriptors for DansGuardian on large system

Need to recompile DansGuardian with the new --with-filedescriptors=N compile option

--with-filedescriptors=N N=MaxChildren Max (yes, yes, I know same as Squid)

Tested with maxchildren=8000 without problem

Keep in mind this is NOT an official release, use at your own risk until an official release date is announced ... Maybe one day ...

From wiki:
The parameter maxchildren should generally be about the same as your peak number of simultaneous users. But attempts to increase this parameter beyond 1018 (the funny number is 1024 - 6) just result in a weird error message that says something about “rabbits”. This never used to matter much, because typical PC hardware couldn't handle more than about a thousand simultaneous users anyway. But some larger faster PC hardware could now greatly exceed this limit

Cette nouvelle version permet de s'affranchir des limites maxchildren en déterminant son maximum lors de la compilation. Particulièrement intéressant pour les gros réseaux ayant besoin de performance.

I'm writing some code now, so other good news very soon, keep in touch.

Squid - Dansguardian

For those who suffer from "maxupload" issues or some old bugs like "dansguardian[723]: Error connecting to proxy"
This is a new version of DansGuardian with many improvements and new features.
Keep in mind this is NOT an official release, use at your own risk until an official release date is announced ...

En attendant que le projet se réveille un jour, voici une version (personnelle) de DansGuardian contenant des correctifs et de nombreuses améliorations (multiples types distincts d'authentification proxy, gestion des timeouts, filtrage dans une liste fermée, corrections de bugs, etc ...)

January 2013 - Dansguardian 2.12.0.4 - alpha
- Set persistent cnx timeout in dansguardian.conf by Frederic Bourgeois
- Multiple auth fixed - checked only with one port - (crash fixed before patch#9) - by Frédéric Bourgeois
- French translation update (accents problem) - by Frédéric Bourgeois
- Added allow regex header filtering with greylist - Frédéric Bourgeois
- MITM issues null ceriticate end date value (fixed) - by Marcelloc
- Concat values resulting in /// on cert path (fixed) - by Marcelloc
- Mitm_magic check code does not work, even if you do not set any mitm key (disabled in code)(ConnectionHandler.cpp) - by Marcelloc
- Re-include general max_upload_size general option - use max_upload_size general value if not set in filtergrouplist - by Marcelloc
- Fixed maxuploadsize silently ignored - all posts blocked - (patch #12) by Frederic Bourgeois
- Applied patch 1 (allow regex filtering with greylist) - by Frederic Bourgeois
- Fixed minor compilation error - by Frederic Bourgeois
- Applied patch 13 (CONNECT broken due to attempted persistency) - by Nils Goroll

Requires three news options: (dansguardian.conf)

# Proxy timeout
# Set tcp timeout between the Proxy and DansGuardian
# Min 5 - Max 100
proxytimeout = 20

# Proxy header exchange
# Set timeout between the Proxy and DansGuardian
# Min 20 - Max 300
proxyexchange = 20

# Pconn timeout
# how long a persistent connection will wait for other requests
# squid apparently defaults to 1 minute (persistent_request_timeout),
# so wait slightly less than this to avoid duff pconns.
# Min 5 - Max 300
pcontimeout = 55

Mamecab OS Retrogaming

Livemamecab is a Mame (arcade games) OS

Livemamecab est un système d'exploitation (linux Xubuntu) dédié au Mamecab, il est utilisable comme live CD, live USB, ou plus classiquement comme OS principal.

Màj de Livemamecab:

• Remaniement de l'interface
  
• Màj Xubuntu precise
  
• Menu Wahcade affichable par le bouton 2 du joystick 1, permettant notamment l'extinction de la borne, sans souris ni clavier.
  
• Changement d'émulateur avec le bouton 1 du joystick 1.
  
• Ajout d'un émulateur snes (pas configuré je suis preneur d'une conf correcte idem pour Megadrive)
  
• Ajout d'un émulateur Megadrive (pas configuré, problème pour quitter l'émulateur la touche escape est obligatoire et je cherche un contournement autre que Qjoypad qui demande les librairies QT) -> Réglé, vu avec le très sympathique mainteneur de Dgen
  
• Ajout de la dernière version de Mame 0.146u3
  
• Mise en place d'une interface graphique de configuration pour le screensaver, il joue les roms automatiquement et sans messages d'avertissements, possibilité de choisir la fréquence ou de le désactiver.
  
• Mise en place d'une interface graphique de sauvegarde/restauration des configs, mame, dgen, zsness, wahcade, etc.
  

EDIT: Plein de nouveautés récemment, pas le temps de faire un changelog complet, je vous conseil de tester le dernier live CD
En vrac
- Des dizaines d'émulateurs avec retroarch
- Un meilleur système de sauvegarde
- 15 Khz (expérimental)
etc ...

VRRPD: 27/04/12

Great documentation about Fwbuilder and Linux Cluster Using VRRP

Un petit mot pour signaler une excellente documentation sur VRRP avec fwbuilder.

Il ne s'agit pas de ma version, mais elle est facilement adaptable.
