Situation réelle de la question

J'ai essayé de configurer sshd sur CM13, ce qui semble assez simple, mais ne semble pas vouloir fonctionner.

J'ai suivi le Article Wiki Doc : sshd mais lorsque j'exécute le 99sshd il produit l'avertissement suivant et les tentatives de connexion se bloquent indéfiniment.

Impossible de charger la clé de l'hôte : /data/ssh/ssh_host_dsa_key

J'ai essayé de décommenter le DEBUG=1 dans l'espoir de découvrir le problème, mais j'obtiens seulement ce qui suit de la part de logcat .

01-21 03:36:24.769 18044 18044 I sshd : debug1: sshd version OpenSSH_6.8, BoringSSL
01-21 03:36:24.771 18044 18044 I sshd : debug1: private host key #0: ssh-rsa SHA256:MMcwKtW+WxaCnIwPHMjHzgOjvdiNOBYPWOVpMKPUw+4

01-21 03:36:24.772 18044 18044 I sshd : debug1: rexec_argv[0]='/system/bin/sshd'
01-21 03:36:24.772 18044 18044 I sshd : debug1: rexec_argv[1]='-f'

01-21 03:36:24.773 18044 18044 I sshd : debug1: rexec_argv[4]='-d'
01-21 03:36:24.773 18044 18044 I sshd : Set /proc/self/oom_score_adj from -1000 to -1000
01-21 03:36:24.773 18044 18044 I sshd : debug1: Bind to port 22 on ::.
01-21 03:36:24.774 18044 18044 I sshd : Server listening on :: port 22.
01-21 03:36:24.774 18044 18044 I sshd : debug1: Bind to port 22 on 0.0.0.0.
01-21 03:36:24.774 18044 18044 I sshd : Server listening on 0.0.0.0 port 22.

Il est fait mention de "key_load_private : incorrect passphrase supplied to decrypt private key", mais il n'est pas précisé pourquoi ni même s'il s'agit d'une erreur.

Il semble également que le Wiki ne soit pas à jour, puisque certaines opérations n'ont pas pu être effectuées exactement comme indiqué, comme le fait de pousser la clé publique.

J'ai également essayé de régénérer manuellement les clés RSA et DSA du serveur, mais aucun changement. Si je commente l'élément HostKey /data/ssh/ssh_host_dsa_key l'avertissement concernant la clé DSA n'apparaît plus, mais les tentatives de connexion sont toujours bloquées. J'ai également essayé ce qui suit ce Gist GitHub mais de même, cela ne fonctionne pas pour CM13.

Ma question est donc la suivante : que faut-il faire pour que le serveur SSH intégré à CyanogenMod fonctionne ? S'il vous plaît noter que je ne suis pas à la recherche de suggestions d'applications, et spécifiquement veulent éviter d'utiliser une certaine application SSH.

Voici le contenu de mon fichier de configuration et de mon script init.

sshd_config :

Mise à jour

A la suggestion d'augmenter la verbosité, voici la sortie de logcat quand je remplace /system/bin/logwrapper /system/bin/sshd -f /data/ssh/sshd_config -D -d con /system/bin/logwrapper /system/bin/sshd -f /data/ssh/sshd_config -D -ddd . Je ne sais pas trop pourquoi (j'ai redémarré depuis le dernier essai), mais il ne se bloque plus et il semble que lorsque j'essaie de me connecter, sshd se plante à la place.

Could not load host key: /data/ssh/ssh_host_dsa_key

Ce n'est pas une erreur fatale, mais un avertissement. Comme vous l'avez déjà trouvé, vous pouvez vous en débarrasser en commentant HostKey de votre sshd_config .

01-21 03:36:24.774 18044 18044 I sshd : Server listening on 0.0.0.0 port 22.

Que voulez-vous que le serveur fasse ? Il attend votre connexion.

mais les tentatives de connexion sont toujours bloquées.

Pourriez-vous vous donner la peine de poster les logs du serveur et du client et comment vous vous connectez ? De préférence, le client avec -vvv commutateurs et serveur avec -ddd au lieu de seulement -d comme dans le script.

Excusez-moi de ne pas répondre à toutes vos questions, mais il y en a trop, pas assez d'informations et ce format ne conviendrait pas à un commentaire.
