Reads the SSH banner and, if you ask, checks that the host key is still the one you know.

设置步骤: Monitor an SSH server

In the address, write the host name or IP address, with the port if it is not 22: "server.home.lan:2222".
To be warned when the server's identity changes, read its fingerprint with ssh-keygen -lf /etc/ssh/ssh_host_ed25519_key.pub.
Paste that fingerprint (SHA256:...) in "Expected host key", or tick "Alert when the host key changes" to record it without choosing one.

注意. The check never logs in and does not verify the server's signature: it reads the key the server shows, like ssh-keyscan.
