Steps:

1. Edit /etc/ssh/sshd_config as follows. Simply uncomment (remove #) the below lines and edit as needed.

   1. Port 2222 # Or any port above 1000
   2. AddressFamily any
   3. ListenAddress 0.0.0.0
   4. ListenAddress ::
   5. PasswordAuthentication yes

2. Restart sshd as: sudo service ssh --full-restart

3. If the above step shows error, such as error: sshd: no hostkeys available -- exiting, then generate the keys as follows: sudo ssh-keygen -A. Then restart sshd again (Step 2).

4. ssh localhost -p 2222 should work now. Enjoy.

Bonus Tip: Use tunnel if you need to make your ssh server (securely) accessible from the internet (across any NAT/Firewall).
