The ssh port is the port used to securely connect to a server. The default ssh port is 22. Changing the ssh port can be useful for several reasons, including:

Security: Changing the ssh port can increase the security of your server. This makes it less likely for attackers to find and attack your server.
Access Control: Changing the ssh port can help you control access to your server. This can help you ensure that only authorized users can access your server.
Congestion: Changing the ssh port can help reduce congestion on port 22. This can improve your server performance.
To change the ssh port, you need to change your ssh server settings. This is usually done in the ssh configuration file. Depending on your operating system, the ssh configuration file may be located in different locations.
