J'utilise pour me connecter avec Windows 7 Pro x64 à mon serveur MySQL hébergé sur un Debian Wheezy avec le client MySQL Workbench en utilisant le "TCP / IP sur SSH" mais cela ne fonctionne pas sur mon nouveau serveur sur Debian Jessie, pourquoi?
Configuration de MySQL Workbench:
Connection Name: TEST
Connection Method: Standard TCP/IP over SSH
SSH Hostname: x.x.x.x:22
SSH Username: root
SSH Password: myRootPa$$word
SSH Key File: <NOT-USING-KEYFILE>
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root
Password: myMySQLPa$$word
J'ai une double vérification de l'adresse IP / nom d'hôte, nom d'utilisateur et mot de passe ...
Configuration du serveur Debian Wheezy:
root @ debian: ~ # cat / etc / debian_version
7.8
mysql> sélectionnez la version ();
+------------------+

Donc, la différence homme est ServerKeyBitsentre les deux fichiers sshd_config ...
L'erreur MySQL Workbench 6.3.3 me donne lorsque j'essaie de me connecter au serveur Debian Jessie :

Plus d'infos:
Le dossier "ssh" n'est pas présent dans:

Règles de pare-feu sur les deux serveurs:
root@debian:~# iptables -vnL
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)

Je peux me connecter avec SSH (KiTTY) sur les deux serveurs ...
J'ai essayé deux versions différentes de MySQL Workbench:
Version 6.3.3.0 build 592 (64 bits)
Version 6.0.9.11421 build 1170 (32 bits)
Ces deux versions fonctionnent avec Debian Wheezy mais pas avec Debian Jessie. Qu'est-ce que je rate?
