I'm running Ubuntu Server 12.04 on a mid-2009 MacBook Pro and using ddclient to update my IP address at After installing ddclient according to the instructions here I had one successful update but none since.

My /etc/ddclient.conf looks like this:

#use=if, if=eth0
use=web,, web-skip='IP Address'

When I run sudo ddclient -daemon=0 -debug -verbose -noquiet I get:

WARNING:  file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword 'ip' = ''
WARNING:  skipping update of Home from <nothing> to [real IP].
WARNING:   last updated <never> but last attempt on Mon Sep 10 09:06:05 2012 failed.

I've tried the solution described in this thread but after running both commands that izx mentions and restarting, the error above still persists thus leaving me unable to update my IP.

Any ideas as to what could be going on? And is there another way to apply the suggested patch?

Thank you!

You can create a free account on, then you sent your ip update there (they have an easy ddclient.conf) they will sent it for you to (and dyndns, and many others if you wish)
