Following on from my video on OpenDNS, heres how to use DDClient to automatically tell OpenDNS (via DNS-O-Matic) when your Dynamic IP address changes. This is a great alternative if your router has no custom DynDNS config options, such as BT Home Hub 3. DDClient can also be used with other services such as DynDNS, No-IP, and DtDNS. Install & Setup Instructions: sudo apt-get install ddclient sudo nano /etc/ddclient.conf daemon=3600 ssl=yes protocol=dyndns2 use=web, web=myip.dnsomatic.com server=updates.dnsomatic.com login=Your OpenDNS login password=Your OpenDNS Password all.dnsomatic.com sudo nano /etc/default/ddclient run_ipup="false" run_daemon="true" daemon_interval=3600 To run it initially: sudo ddclient -daemon=0 -debug -verbose -noquiet Once setup it will automatically run when your system is booted up, and send updates once every one hour (3600 seconds) For more information see: https://help.ubuntu.com/community/DynamicDNS DNSOMatic: https://www.dnsomatic.com/ OpenDNS: http://www.opendns.com/ OpenDNS Video: https://www.youtube.com/watch?v=h2Qa1xqO2v4
