Help with OPENDNS Linux IP UPDATER

[PizzaGrease]

Hi,

I've been using OPENDNS and Linux IP UPDATER without issue until recently (AFAIK). I changed my password a few weeks ago and last week I realized the IP address wasn't changing. In troubleshooting, I realized I neglected to also change my password in /etc/ddclient.conf, so I updated it with the new password. After changing the password in the .conf file, I'm not sure that the updater or ddclient is working correctly. So I'd like help please.

I've set up following this article:
https://support.opendns.com/hc/en-us/articles/227987727-Linux-IP-Updater-for-Dynamic-Networks

##
## OpenDNS.com account-configuration
##
protocol=dyndns2
use=web, web=myip.dnsomatic.com
ssl=yes
server=updates.opendns.com
login=opendns_username
password='opendns_password'
opendns_network_label

From the CLI,
$ sudo service ddclient status

Does dyndns2 need to be changed to something else?

Thanks,

So I had this problem. I installed ddclient 3.9.1-7, but I don't think that solved b/c I was still getting the FAILED message like you.

All of this is from using ChatGPT

Check for multiple config files:

ls -l /etc/ddclient.conf /etc/ddclient/ddclient.conf 2>/dev/null
sudo grep -RIn . -e 'protocol=|server=|login=|password=|opendns_networklabel' /etc/ddclient* 2>/dev/null

Nuke line ending characters

sudo sed -i 's/\r$//' /etc/ddclient.conf
sudo perl -pi -e 's/[ \t]+$//' /etc/ddclient.conf
sudo nl -ba /etc/ddclient.conf | sed -n '1,120p'

Check that the default file isn't adding surprises

sudo sed -n '1,200p' /etc/default/ddclient

 Restart, then run once in the foreground with full debug

sudo systemctl restart ddclient
sudo ddclient -daemon=0 -debug -verbose -noquiet

You should see exactly one attempt ending with good <IP> or nochg <IP>.

No unexpected status (12). No protocol <undefined>.

I hope this helps if you haven't got it sorted yet.
