Comment avoir des logs moins verbeuses

Support Debian
#1

Bonjour,

Je recherche à faire en sorte que mes logs soient moins verbeuses.
Exemple, je demarre mon raspberry PI, j’ai dans vars logs:

[code]
ls -lrt

…
-rw-rw-r-- 1 root utmp 820224 Jan 2 15:49 wtmp
-rw-rw-r-- 1 root utmp 292584 Jan 2 15:49 lastlog
-rw-r----- 1 root adm 400648 Jan 2 15:54 auth.log
-rw-r----- 1 root adm 249539 Jan 2 15:54 daemon.log
-rw-r----- 1 root adm 2822309 Jan 2 15:54 syslog
-rw-r----- 1 root adm 2353246 Jan 2 15:54 messages
-rw-r----- 1 root adm 2382127 Jan 2 15:54 kern.log[/code]
Les fichiers modifié juste au démarrage.

quand je regarde à l’interieur, j’ai

Tout ça semble venir du dongle Wifi mais est-il possible de dire au driver de logger seulement ce qui est en “warn”?

Les infos de rigueur, comme c’est mon 1er post sur le forum:

?

Sans garantie. Pas trouvé debug propre à rtl8188e.

Bonjour,

modinfo ne donne rien:

pi@raspberrypi / $ modinfo rtl8188e ERROR: Module rtl8188e not found.

J’ai recherché des debug.h, je n’en trouve que 3. je n’ai rien trouvé d’utile dedans.

pi@raspberrypi / $ sudo find . -name debug.h ./usr/include/linux/nfsd/debug.h ./usr/include/linux/sunrpc/debug.h ./usr/include/c++/4.6/debug/debug.h

Je vais rechercher comment mettre le rtlwifi_debug en liste noir.
Merci pour la réponse tt de même.
Xavier.

rtlwifi/debug.h se trouve dans les sources du noyau régulier linux.
Cependant, étant donné que tu utilises les binaires de chez realtek, on peut imaginer que la loquacité du debug n’en dépende pas.
Il faudrait donc chercher dans les sources du module rtl8188eu de chez realtek.

Trouvé sur la toile, un guide pour compiler rtl8188eu en raspbian qui semble avoir repéré la cause :

tech.enekochan.com/tag/compile/

…

[quote] very verbose at boot time because it has a debug flag defined. To get rid of those messages comment this line:

Remarque :

[quote] NOTICE!

Linux kernel 3.12 now has built-in support for this wifi dongle.[/quote]

#6

Parfait.
Merci pour les infos. Je sais ce qu’il me reste à faire.
