Uso per connettermi con Windows 7 Pro x64 al mio server MySQL ospitato su un Debian Wheezy con il client MySQL Workbench usando "TCP / IP over SSH" ma non funziona sul mio nuovo server su Debian Jessie, perché?
Configurazione di 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
Ho ricontrollato l'indirizzo IP / nome host, nome utente e password ...
Configurazione del server Debian Wheezy:
root @ debian: ~ # cat / etc / debian_version
7.8
mysql> select version ();
+------------------+

Configurazione del server Debian Jessie:

mysql> select version ();

Quindi la differenza uomo è ServerKeyBits
tra i due file sshd_config ...
L'errore MySQL Workbench 6.3.3 mi dà quando provo a connettermi al server Debian Jessie :

Altre informazioni:
La cartella "ssh" non è presente in:
C:\Users\myUser\AppData\Roaming\MySQL\Workbench
Regole del firewall su entrambi i server:
root@debian:~# iptables -vnL
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)

Posso collegarmi con SSH (KiTTY) su entrambi i server ...
Ho provato due diverse versioni di MySQL Workbench:
Version 6.3.3.0 build 592 (64 bits)
Version 6.0.9.11421 build 1170 (32 bits)
Queste due versioni funzionano con Debian Wheezy ma non con Debian Jessie. Cosa mi sto perdendo?
