Change default SSH port

By default, SSH runs on port 22. This leads to thousands of automatic scans and scripted attacks being launched.

No reason not to change your port exists to the best of my knowledge. Get it changed!

Add a line in the file /etc/ssh/sshd_config:

Port 6969

Reload sshd

#/etc/rc.d/sshd reload
OR
service sshd restart

A couple of simple things here will ensure you of success:

Check that whichever port you choose is not already in use
After restarting ssh, do not close that window. Instead, open a new connection leaving the existing connection open. If anything has gone wrong and you wish to revert your changes back, you can do so in your existing window.
