Linux maintains ssh connection implementation code
Often when we use ssh to remotely connect to a host, the connection will be automatically disconnected due to no operation for a long time, which is very inconvenient.
By configuring the ssh server or client, we can maintain the ssh connection.
Server configuration
vim /etc/ssh/sshd_config, add the following configuration:
# 表示每30秒服务端就向客户端发送一个数据包来保持连接 ClientAliveInterval 30 # 如果发送了60次客户端都还没有回应，就断开连接 ClientAliveCountMax 60
Client configuration
vim /etc/ssh/ssh_config, add the following configuration:
# 表示每30秒服务端就向服务端发送一个数据包来保持连接 ServerAliveInterval 30 # 如果发送了60次服务端还没有回应就断开连接 ServerAliveCountMax 60
