Avé tout le monde.

Je vous soumets un problème qui doit sans doute être peu compliqué pour un veritable admin, mais qui me gâche la fête depuis hier.

J'ai migré avec succès de Debian 9 à 10. Tout s'est bien passé sauf :

mon accès ssh/sftp ne marche plus, le serveur ssh ne répond pas OU refuse la connexion, malgré mes précautions (j'avais demandé de garder le fichier de config existant). ssh/sftp marchait bien sous Debian 9.

Message PuTTY :

"Network error : connection refused"

Message de Core FTP LE :

"Resolving xx.xxx.xxx.xxx…

xx.xxx.xxx.xxx [22] connecting…

SFTP connection error - Connection timed out
Can't establish connection --> xx.xxx.xxx.xxx:22 @ Thu Nov 07 15:24:34 2019 (10038-10060) :

Mon serveur chez OVH :

Operating system    Debian Linux 10
Webmin version  1.930
Kernel and CPU  Linux 3.8.13-xxxx-grs-ipv6-64-vps on x86_64
Processor information   AMD Opteron(tm) Processor 6128, 4 cores

PHP 7.2.24-1+0~20191026.31+debian8~1.gbpbbacde (cli) (built: Oct 26 2019 16:08:53) ( NTS )

J'ai donc desinstallé openssh-server et openssh-client 

apt-get remove openssh-server openssh-client --purge

et nettoyé

apt-get autoremove 
sudo apt-get autoclean

avant de rechercher à nouveau ces deux packages 

apt-get update

Voici ce qui se passe quand je reinstalle openssh-server et openssh-client ("-y --force-yes -f" permet de passer la confirmation de continuation au script, dans webmin)

apt-get -y --force-yes -f install openssh-server openssh-client

Je sais qu'il y a des erreurs pour d'autres modules, mais n'ont toutefois pas causé des problèmes tout au long de la migration Debian 7 > 8 > 9 :

grub-pc
keyboard-configuration
console-setup
console-setup-linux

(mais je peux me tromper !)
A rectifier … une fois que mon accès ssh/sftp remarche !

Merci de vos lumières, et de votre précieuse assistance !

    • Tes erreurs de permissions denied sont louches, Ta partition est bien en montée en lecture/écriture ? Tu n'as pas fait un chattr +i sur /etc ?
    • Regarde tes logs via journalctl -xu ssh
    • Regarde tes logs /var/log/syslog
    • Si tu fais un netstat -lpn |grep 22 tu as quelque chose ?
    • Réinstalle les paquets openssh en forçant le reset des configurations : mv /etc/ssh{,.old} apt-get -o DPkg::options::=--force-confmiss --reinstall install openssh-client openssh-server openssh-sftp-server

    Is it a Bird? Is it a Plane?? No, it's Super Poil !!!

      Bonjour, je dis sans doute une énorme connerie (patapé, patapé), mais Buster avec Gnome bloque les connexions entrantes pas défauts, non? Soit: paramètres/partage/connexions distantes: activées?

      Sommaire

      Merci M.Poil !

      Re : permissions louches : yep, y a souci je crois… Partition OK MAIS visiblement problème dans /etc car impossible d'y faire quoi que ce soit - j'ai pas réussi à ajouter un fichier, renommer, effacer le moindre élément. Tests fait dans /etc/, /etc/default/keyboards, /etc/ssh/, /etc/Imagemagick :

      "failed to create: test : No such file or directory"

      J'ai pas sciemment fait chattr +i sur /etc

      journalctl -xu ssh

          Bonjour l'ami fan de Tolkien !

          Avec une commande, le problème se volatilisa !

          PuTTY et Core FTP remarche comme avant…

          Je suppose que vous avez déjà rencontré ce type d'erreur ? Combien d'années de métier ?

          Un très grand merci pour votre apport - comment évaluer votre réponse svp ? Je suis nouveau sur le forum…

              M. Poil,

              C'est souvent comme ça dans la vie ;-)

              Grace à tes suggestions, j'ai pu accéder à des logs dont j'ignorais l'existence. La réponse était, en effet, écrite noir sur blanc !

              Mais j'avais déjà passé la journée à chercher des solutions via Google, et rien marchait… Je commençais à fatiguer.

              En tout cas, il reste un problème de droits dans /etc qui provoque des erreurs à l'installation d'autres packets, je vais tranquillement revisiter cela et peut-être poser d'autres questions.

              Un grand merci à silmaril et à toi, c'est très apprécié.

              Christian

                Mais j'avais déjà passé la journée à chercher des solutions via Google, et rien marchait… Je commençais à fatiguer.

                parce qu'en général les gens cherchent des solutions "finales" sur google en se basant sur un problème générique, au lieu de lire tout simplement ce que le système renvoi ^

                Je suppose que vous avez déjà rencontré ce type d'erreur ?

                Celle la non pas particulièrement, mais les appli qui ne demarrent pas en général oui ^

                Combien d'années de métier ?
                Heu, 15 de métier, 20 de linux et 30 d'informatique en général XD

                Pour être plus précis dans ton premier "dump" il y avait:

                Job for ssh.service failed because the control process exited with error code.
                See "systemctl status ssh.service" and "journalctl -xe" for details.

                systemctl status ssh.service

                ssh.service - OpenBSD Secure Shell server
                Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: enabled)
                Active: failed (Result: exit-code) since Thu 2019-11-07 15:24:53 CET; 18s ago
                Docs: man:sshd(8)
                man:sshd_config(5)
                Process: 31292 ExecStartPre=/usr/sbin/sshd -t (code=exited, status=255/EXCEPTION)

                Deux écoles ici, soit à la systemd, lancer: "systemctl status ssh.service" puis "journalctl -xe" si le premier n'aide pas assez.

                Soit directement lancer à la main "/usr/sbin/sshd -t", qui est la commande utilisé par systemd pour vérifier que le service peut démarrer (dans le cas du service ssh) et qui ici à renvoyé une erreur (status=255/EXCEPTION), vous aurais sorti directement le message

                  Merci silmaril pour ce post-mortem…

                  En te relisant, je me rends bien compte qu'il faudra que je me forme pour acquérir des compétences nécessaires à me dépanner pour mes propres projets. La passation, à l'époque, en SSL m'avait bien pourri la vie pendant des jours…

                  Question : existe-t-il des formations gratuites ou payantes pour obtenir une compétence un peu polyvalente en gestion de serveurs ? En tant que bidouilleur invétéré depuis le début des années 90, je ne suis pas un débutant, et absolument pas expert. Quand ça casse, il y en a pour des jours - je ne peux pas continuer comme ça ;-)

                  Non pas une formation diplômante, juste de quoi être à l'aise avec les manips courantes d'un serveur comme le mien chez OVH.

                  C'est probablement un sujet qui mérite son propre fil…

                    1. lire les logs (vu que c'était marqué dedans)
                    2. apprendre l'anglais car beaucoup de logiciel parle en anglais
