Ubuntu Server 10.10 Maverick:

ddclient just stops working

The log shown (in verbose debug mode) 

Sep 20 13:53:13 zambas ddclient[3531]: CONNECT:  checkip.dyndns.com:8245

What could be causing this? The link does have packet loss from time to time, but surely that should not cause ddclient to stop responding?

    How long did you actually waited? It looks like a timeout problem: either ddclient should get a timeout or it should get an answer. By default it should wait 120seconds.

    The process typically stops responding some time during the night and then 6 or 10 hours later, when I can't connect to the server because the IP address change was not updated in the DNS record, I realise the process is hanging. It never times out.
