STEP 1
Install ddclient
sudo apt-get install ddclient
If you are changing DNS service provider, just reconfigure ddclient
sudo dpkg-reconfigure ddclient
STEP 2
Enter required fields. I’m using dynu.com
Dynamic DNS service provider: others Dynamic DNS server: api.dynu.com Dynamic DNS update protocl: dyndns2 Username for dynamic DNS service: your-user-name Password for dynamic DNS service: password Network interface used for dynamic DNS service: ethx DynDNS fully qualified domain names: xxx.dynu.com
STEP 3
Let’s make it more secure by using SSL
sudo apt-get install ssh libio-socket-ssl-perl sudo nano /etc/ddclient.conf
protocol=dyndns2 #use=if, if=eth1 use=web, web=ipv4.kim.sg/, web-skip='IP Address' server=api.dynu.com login=xxxxxxxxx password='xxx' xhostnamex.dynu.com daemon=600 ssl=yes
STEP 4
Run ddclient as daemon. Simply change run_daemon=false to true
sudo vim -c '%s/run_daemon=\"false\"/run_daemon=\"true\"/gc' -c 'wq' /etc/default/ddclient
Troubleshooting:
sudo ddclient -daemon=0 -debug -verbose -noquiet | less
Check your current DNS servers
cat /etc/resolv.conf
Remove/purge all of the previous install attempts:
sudo apt-get remove --purge ddclient
Restart ddclient daemon
sudo service ddclient restart
