I am having a really hard time getting
ddclient (which updates OpenDNS with my current IP address) to work. I have it running as a daemon, but it never succeeds in updating my IP address at
To troubleshoot, I am running
ddclient from the command line as follows.
(In these examples, values in square brackets  are stand-ins for the real values for security reasons)
use=web, web=checkip.dyndns.org/, web-skip='IP Address' server=updates.opendns.com protocol=dyndns2 login=[my login] password=[my password] Home
When I run:
sudo ddclient -daemon=0 -debug -verbose -noquiet
WARNING: file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword 'ip' = '' ... WARNING: skipping update of Home from <nothing> to [my real ip]. WARNING: last updated <never> but last attempt on Tue Oct 4 08:38:32 2011 failed.
rm the cache file,
ddclient does work once, but then it fails on subsequent times.
