Sync dynamic IP with openDNS service via ddclient
Setup openDNS in system settings
Set DNS addresses in resolv.conf file:
sudo gedit /etc/resolv.conf.head
with code:
nameserver 208.67.222.222
nameserver 208.67.220.220
Port forwarding
The ddclient daemon need opened incoming connections for ports 53, 443 and 80. If you using a firewall software and router device You need in the settings to allow connections to these ports, otherwise ddclient daemon can't working propertly and sending IP to openDNS servers failed with errors. Check status ddclient daemon by command:
sudo systemctl status ddclient -l
Looking for similar warnings:
ddclient[8999]: WARNING: cannot connect to myip.dnsomatic.com:80 socket: IO::Socket::INET: Bad hostname 'myip.dnsomatic.com'
If port forwarding is propertly setup, these warnings will be not showed and this mean all is fine.
