In reply to Ezeelogin. Try ssh -p 34627 user@ command.

Did all the steps but now I cannot log in to SSH anymore, on port 22 it says connection refused, and on the port, I defined it says connection timed out. Any help on this? Btw I added it on Plesk firewall as both income and outgoing rules and please visit us: https://www.ezeelogin.com.

Thanks for the article.

Updated firewall as below for centos7, works smooth.

$ sudo firewall-cmd --permanent --zone=public --add-port=34627/tcp
$ sudo firewall-cmd --reload

Each open port can be discovered, but adding an obscurity layer makes it harder for bots, for instance, to discover a service running on a well-known or standard port.

Security through obscurity is not security. A simple nmap -sV will discover your new ssh port on minutes.
