After you connect to the server by using an SSH command, if you do not perform the operation for a period of time, when you enter terminal again, there will be no response for a period of time, and an error prompt will appear:

packet_write_wait: Connection to 47.92.226.106 port 22: Broken pipe

You can only use the SSH command to connect again.

 

Solution:

 

1. If you have multiple servers and do not want to set them on each server, you only need to set them on the client:

• Keep all connections: (root access required), Edit/etc/ssh/ssh_config
• Set: edit on your user only~/.ssh/config(Create the file if it doesn't exist)

Host *
　　ServerAliveInterval 300    

　　ServerAliveCountMax 2

 

2. If there are multiple personal management servers, you can configure them on the server side:

Make your OpenSSH server keep alive all connections with clients by adding the following/etc/ssh/sshd_config:

ClientAliveInterval 300ClientAliveCountMax 2

 

These settings allow the SSH client or server to send an empty package to the other end every 5 minutes.

If it does not receive any response after two attempts, give up. The connection is disconnected.
