Solve the situation that the terminal is stuck after logging in to the server without operation for a period of time

The stuck is due to the problem of LIUNX security settings. It will be automatically disconnected if no data is used for a period of time. The solution is to let the local or server send a request to the other party every other time.

Open the configuration file locally (not recommended to set on the server side)

 sudo vim /etc/ssh/ssh_config

Add the following parameters at the end of the file, and remove the following comments when adding

ServerAliveInterval 50  #每隔50秒就向服务器发送一个请求
ServerAliveCountMax 3  #允许超时的次数，一般都会响应

Restart the ssh service after modification

sudo /etc/init.d/ssh restart
