ssh: Run sshd in the foreground.

sshd

$ sshd -D

try on your machine

The command sshd -D is used to start the OpenSSH server in the foreground with debug mode enabled.

Here is a breakdown of the components:

sshd: It stands for Secure Shell Daemon. sshd is the server component of the OpenSSH (Secure Shell) protocol and handles incoming SSH connections. It provides secure remote access to a system through encrypted communication channels.
-D: It is a command-line option for sshd. When used, it instructs sshd to run in debug mode. Debug mode provides detailed information about what is happening during the SSH session, such as authentication details, connection establishment, and other relevant data. It is useful for troubleshooting purposes to understand and diagnose any issues.

By running sshd in debug mode, you can monitor the server's activities in real-time, allowing you to track any errors or unexpected behavior. It helps in identifying and resolving problems related to SSH connections and configurations. Note that running sshd in debug mode should generally be done in testing or troubleshooting scenarios, rather than in a production environment.
