Saya menggunakan untuk terhubung dengan Windows 7 Pro x64 ke server MySQL saya yang di-host pada Debian Wheezy dengan klien MySQL Workbench menggunakan "TCP / IP over SSH" tetapi tidak bekerja pada server baru saya di Debian Jessie, mengapa?
Konfigurasi 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
Saya sudah mengecek alamat IP / nama host, nama pengguna dan kata sandi ...
Konfigurasi server Debian Wheezy:
root @ debian: ~ # cat / etc / debian_version
7.8
mysql> pilih versi ();

Konfigurasi server Debian Jessie:

Jadi perbedaan pria adalah ServerKeyBitsantara dua file sshd_config ...
Kesalahan yang diberikan MySQL Workbench 6.3.3 ketika saya mencoba terhubung ke server Debian Jessie :

Lebih banyak info:
Folder "ssh" tidak ada di:
C:\Users\myUser\AppData\Roaming\MySQL\Workbench
Aturan firewall di kedua 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)
pkts bytes target prot opt in out source destination
Saya dapat terhubung dengan SSH (KiTTY) di kedua server ...
Saya telah mencoba dua versi berbeda dari MySQL Workbench:
Version 6.3.3.0 build 592 (64 bits)
Version 6.0.9.11421 build 1170 (32 bits)
Kedua versi ini bekerja dengan Debian Wheezy tetapi tidak dengan Debian Jessie. Apa yang saya lewatkan?
