sudo apt-get install inadyn

sudo nano /etc/inadyn.conf

--username ********
--password ********
--update_period 3600
--forced_update_period 21600
--alias masteras.mooo.com,a2tMNjAzd3huVzR5MXExdFJIc246MTI5ODMxMjk=
--dyndns_system [email protected]
--verbose 5

Now, we need to ensure that the DNS updater (Inadyn) runs automatically after every re-boot

export EDITOR=nano && sudo crontab -e

Add the following line:

@reboot /usr/sbin/inadyn
*/5 * * * * /usr/sbin/inadyn

Reboot system and then run the following command to ensure inadyn is running:

ps -A | grep inadyn
