（接上一條）解決ssh隧道斷開自動重連的問題

Sounds like you need autossh. This will monitor an ssh tunnel and restart it as needed.

Autossh example

autossh -M 5122 -N -R 5022:localhost:22 rex

Explanation:

Forward port 5022 on rex (the remote machine) to port 22 on localhost (the local machine).

Use port 5122 and 5123 will be used for connection monitoring.

 

還有個問題是自動重連的時候要輸password，這樣寫.sh script就有點問題

解決方法就是ssh-keygen生成 rsa key 免密登陸。這里不贅述了。
