ddclient WARNING: unable to determine IP add

[Nobody/Anonymous]

Hi,

I have tried to install ddclient on Ubuntu. It worked fine once and now this time, I get this message where it cant resolve the IP!!

$ddclient
WARNING:  unable to determine IP address

What can cause this?? and how to fix it? (I am behind a router, here is the results of my ifconfig)

Thanks

Please post the full result of ddclient -daemon=0 -debug -verbose -noquiet and your ddclient.conf for further debugging.

I'm getting this exact same message.  ddclient appears to have stopped working for me quite some time ago as I'm unable to locate any logging over the past few months.  I grabbed the 3.6.6 figuring DynDNS had made some back end changes that the client I had installed (mandrake rpm versioned 3.6.5) was not aware of.  Follows is the output using the above command suggested:

Ahh, yes, further information to the above.  The machien the client is running on is on a private subnet behind a NAT enabled router.

[drobosson]

Disregard, the information in the post below titled "client not updating DNS" contained the suggested fix.

I think you're missing a use-statement in your ddclient.conf  Oh, btw, the location of ddclient.conf has changed.  To make it possible to run it as a different user as root, ddclient expects his configuration in /etc/ddclient/ddclient.conf
