Use autossh to Ensure ssh Tunnel Stability

Using autossh to ensure the stability of the ssh tunnel we recently hope to establish is reliable. Sometimes the process is still in progress, but the connection is no longer valid. Autossh is a good thing. Installing apt-get install autossh in Ubuntu is simple, for example, the original command of Using ssh: [plain] ssh-N-v-D localhost: 8527 root @ remote_ssh_server-p remote_ssh_port is now changed to [plain] autossh-M 5122-N-v-D localhost: 8527 root @ remote_ssh_server-p remote_ssh_port. -M 5122 is the port used by the server echo mechanism. Although I do not quite understand the usefulness, adding it does not affect my work.
