CentOS - Jun 2012 - Request for recommendations for dynamic dns daemon

Greetings,

I'm trying to configure dynamic dns on my test/backup machine (CentOS 
5.8). I'm using Zoneedit DNS.

I've been trying to setup ddclient; the error message that I get is:
Jun 26 15:20:09 xxxxxx ddclient[28467]: WARNING:  file 
/var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword
'ip'
= ''

Or should I use ez-ipupdate?

Thank you.
