If the SSH connection port is 22 on your server which is default and this is a security issue. The port 22 does receive brute force and DDOS attacks often. Login to your root SSH and edit the file /etc/ssh/sshd_config and find the line #port 22. Uncomment it and change the port to something like 2244, 2233. Then run the following commands one by one. If you lose SSH connection or something wrong, you can always hard reset your SSH from the SonicPanel, on the left menu under the restart services at the bottom which will revert your changes to default settings.
- semanage port -a -t ssh_port_t -p tcp PORT
(eg: semanage port -a -t ssh_port_t -p tcp 2244) - systemctl restart sshd
You can also contact your server provider support to change your SSH port if you are unable to make the changes.
