CentOS SSH Command

Use SSH to remotely log in to the CentOS system
Common formats are: SSH [[email protected]]hostname [Port]
Detailed commands can: Man SSH

As an example:
Do not specify User:
SSH 192.168.0.1
Specify User:
SSH [email protected]
Specify port: (22 is the default port for SSH)
SSH 192.168.0.1 22
SSH [email protected] 22

Of course we can change the port number by modifying the SSH configuration file,/etc/ssh/sshd_config
To avoid being scanned by malicious ports
Vim/etc/ssh/sshd_config
Found it
#Port 22
Remove comments
Change the port number 22 to a 5-digit number, such as 54321, not greater than 65535.
Port 54321
: Wq

Restart the SSH service
Service SSH Restart

SSH [email protected] 54321
We can land.
