ddclient 3.8.3 from EPEL on Centos 7 is not updating IP in namecheap

[Rodrigo]

Hi,

I am running ddclient 3.8.3 from EPEL repository on Centos 7.

THE PROBLEM: Ddclient seens that get the IP address properly but this is not updated in Namecheap Server. There is no warning or error messages in Logs.

As a reference, consider the domains facilitasegtec.com.br and donachicatapiocaria.com.br.

Look to the following configurations and logs:

1 - Namecheap

Domain: donachicatapiocaria.com.br
Record: A
Host: @
IP: It does not updated

Domain: facilitasegtec.com.br
Record: A
Host: @
IP: It does not updated

2 - vi /etc/ddclient.conf

use=web,
web=dynamicdns.park-your-domain.com/getip \ protocol=namecheap, \ server=dynamicdns.park-your-domain.com \ login=facilitasegtec.com.br, \ password=9bb79cdb45bb40ee997c3661b3096826 \ @.facilitasegtec.com.br

use=web,
web=dynamicdns.park-your-domain.com/getip \ protocol=namecheap, \ server=dynamicdns.park-your-domain.com \ login=donachicatapiocaria.com.br, \ password=faa57d987b744723b58c96662dd02fbd \ @.donachicatapiocaria.com.br

You should try again with your cache file removed and post the complete output of ddclient -daemon=0 -noquiet -debug -verbose to pastebin and leave a link here.
Are you sure you use '@' in the configuration of namecheap? I've never used their service but it looks like ddclient tries to update the host called @.donachicatapiocaria.com.br while it should be '@.donachicatapiocaria.com.br'. I understand this confusing because the bind configuration will use @ as reference to donachicatapiocaria.com.br but your configuration should contain donachicatapiocaria.com.br as hostname.

I know this is an old thread but I have tried the debug from @wimpunk and it works flawlessly. It updates the namecheap DNS entries with the correct IP addresses.

• I have the folder /var/run/ddclient and it is owned by ddclient.ddclient with 744 permissions.
  The folder contains 0 files but the application is not running.

• Further, I have removed the DDCLIENT_OPTIONS="-deamon 300" from the /etc/sysconfig/ddclient.

Yet I continue to have the failure to start the ddclient as a service.

Any other suggestions?

[wimpunk]

Check the latest development version on github. There's a fix for systemd in that version.

Thanks!

I ran into the same issue. I've fixed by updating these two files
- chown -R chown:chown /var/cache/ddclient
- chown -R chown:chown /var/run/ddclient
