Update your OpenDNS network ip

Intended for dynamic ip OpenDNS users, this command will update your OpenDNS network IP.

For getting your IP, you can use one of the many one-liners here on commandlinefu.


I use this in a script which is run by kppp after it has successfully connected to my ISP:



IP="`curl -s http://checkip.dyndns.org/ | grep -o '[[:digit:].]\+'`"


if [ "$IP" == "" ] ; then echo 'Not online.' ; exit 1


wget -q --user=topsecret --password="`echo $PW | xxd -ps -r`" 'https://updates.opendns.com/nic/update?hostname=myhostname&myip='"$IP" -O -

/etc/init.d/ntp-client restart &



PS: DynDNS should use a similar method, if you know the URL, please post a comment. (Something with members.dyndns.org, if I recall correctly)


There are 5 alternatives - vote for the best!

What others think

For DynDNS just use ddclient or Inadyn. Inadyn does NOT use https but ddclient does. My fav part of users script is that it uses DynDNS' checkip to update his/her OpenDNS account.

inadyn does a superb job. I prefer it very much to ddns. inadyn allows you to have multiple dyndns domains updated in one instance of the app. ddclient does not. inadyn > ddns imo

shout out to inadyn developers -- great job guys!

+1 for Inadyn > ddclient

@eGGstain Well, I have my own script on my webserver (just a php command, thats all) that returns my IP. And because I don't want to make that too public ;-) , I looked for a command to replace that and used the dyndns one from here.
