ddclient not working

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,

I use ddclient to update the IP of my server in dyndns, but it doesn't 
work: the IP does not get set. It has been working for years.

I have to go manually into dyndns and set the IP and the one that it has 
is stale.

All I see is:
hugo@HDBB:~$ ps ax | grep -i ddclient
 1792 ?        S      0:00 ddclient - sleeping for 50 seconds

There are no ddclient messages in syslog.

ii  ddclient                  3.8.0-11.3                address updating 
utility for dynamic DNS services

How does one debug this?
