How to change the SSH port on Linux server

Run the command to locate sshd_config file:

find / -name "sshd_config" 2>/dev/null

Sample outputs:

[[email protected] ~]# find / -name "sshd_config" 2>/dev/null
/etc/ssh/sshd_config
[[email protected] ~]#
Edit the file and set Port option

Type the following command:

nano /etc/ssh/sshd_config

Locate the line that read as follows:
Port 22
OR
#Port 22

To set the port to 2222, enter:
Port 2222

Save and close the file. Please note that port numbers 0-1023 are reserved for various system services. Hence, I recommend choosing port numbers between 1024 and 65535.

Restart the sshd service using the command:

service sshd restart
