Bonjour,
Mon serveur bourre : je dois le redémarrer tout les jours... Je suppose que je suis hacké mais c'est pas sûr. Comment est-ce que je peux faire?
Meilleures salutations.

Hello !
Je ne connais pas gentoo, mais as-tu regardé tes logs avec dmesg ? Est-ce que tu as encore assez d'espace disque ? Est-ce que tu as essayé de scanner ton système avec clamscan -i -r / (ça sera un peu long) ?

Salut,

Resalut,
En fait j'ai fait un df -ih
df -ih Filesystem Inodes IUsed IFree IUse% Mounted on rootfs 1.3M 1.3M 0 100% / /dev/root 1.3M 1.3M 0 100% / /dev 4.0M 290 4.0M 1% /dev /dev/md2 5.8M 318K 5.5M 6% /home tmpfs 4.0M 1 4.0M 1% /dev/shm /dev/loop0 126K 1.1K 124K 1% /tmp /dev/loop0 126K 1.1K 124K 1% /var/tmp
Je ne sais pas comment vider les inodes....

Salut,
J'ai réussi à vider les inodes
df -ih Filesystem Inodes IUsed IFree IUse% Mounted on rootfs 1.3M 154K 1.1M 13% / /dev/root 1.3M 154K 1.1M 13% / /dev 4.0M 290 4.0M 1% /dev /dev/md2 5.8M 318K 5.5M 6% /home tmpfs 4.0M 1 4.0M 1% /dev/shm /dev/loop0 126K 22 125K 1% /tmp /dev/loop0 126K 22 125K 1% /var/tmp
Il me semble que exim me remplit trop vite mon serveur....
Que faire???

Salut,
En fait un virus chez un client envoyait des tonnes d'email au moyen du serveur. Ces emails gonflaient la queue exim, je ne sais pas pourquoi et faisait que les inodes arrivaient à 100%. Ce qui mettait finalement le serveur en panne. Après avoir analysé les logs exim, j'ai pu changer le mot de passe de l'utilisateur qui était vérolé pour provisoirement rétablir le serveur.
Meilleures salutations.
Jean.
