Configure the ssh connection to be uninterrupted

Solution 1: The server actively keeps the connection

Log in to the server and open the ssh configuration file

vim /etc/ssh/sshd_config

Add the following statement

ClientAliveInterval 120
ClientAliveCountMax 720

Restart sshdservice

systemctl restart sshd

• The first sentence means that the server will send an empty packet to the client every 120s.
• The second sentence indicates that the server will send a maximum of 720 times, 120*720=24 hours
• The connection will not be disconnected during 24 hours

Solution 2: The client actively keeps the connection

Edit ~/.ssh/configfiles, increasingServerAliveInterval 120

Host server
    HostName xxx.domain.local
    ServerAliveInterval 120
    User root

Send an empty packet to the server every 120 seconds
