Bonjour à tous,
Je dispose d’un serveur dédié tournant sous Debian Squeeze et hier j’ai installé un certificat SSL signé par Gandi (je ne sais pas si c’est lié) puis j’ai lancé apt-get update/upgrade/dist-upgrade puis j’ai reboot le serveur et… Plus rien. J’ai attendu 10/15 minutes et toujours aucunes connexion que ça soit en HTTP, en SSH, ou en FTP, j’ai même essayé de le ping, mais rien. Du coup je l’ai redémarré en mode “rescue” depuis le panel de l’hébergeur, je suis donc allé voir le syslog, mais je n’ai rien vu d’anormal, je vous le copie donc ici :
