Dynamic DNS Script Not Updating DNS Records.

Avatar forum:exc414 3 years, 2 months ago


I use a DDNS script that is executed daily (as a cronjob) to update my DNS records with the correct IP that I am given by my ISP (Verizon).

However, as of today it stopped working. Even manually running the script from different computers nothing gets updated. Below is my script and the output it gives.


#set -x

#Private Key

#Domain ID

#Resource ID


#Echo the date of the update once
echo "Updated on $(date) : " >> $LOGFILE

#The param remote_addr automatically gets the IP of the machine that the request was made from.
for index in 1 2 3 4 5
        wget --inet4-only -qO- --no-check-certificate "$URL" >> $LOGFILE

exit 0

Output :

  4 Updated on Sat Feb 13 21:51:55 EST 2016 :

{"ERRORARRAY":[],"DATA":{"ResourceID":5494854},"ACTION":"domain.resource.update"}{"ERRORARRAY":[],"DATA":{"ResourceID":5494843},"ACTION":"domain.resource.update"}{"ERRORARRAY":[],"DATA":{"ResourceID":5494856},"ACTION":"domain.resource.update"}{"ERRORARRAY":[],"DATA":{"ResourceID":5494857},"ACTION":"do    main.resource.update"}{"ERRORARRAY":[],"DATA":{"ResourceID":5494855},"ACTION":"domain.resource.update"}

Things I have done :

Delete the old key, resource id and domain id. I made new ones.

Run the script from 3 different machines. (Centos 6.5, Windows 7 and Windows Server 2012)

Run it manually from the CLI.

Checked the API Docs to make sure I am using domain.resources.update correctly.

I don't get any of the errors shown in the API docs as shown by the above output.

I am asking for any possible clues as to why it is not updating/failing or how to troubleshoot it further?

Thank you.

As shown in the output, the API calls are working fine. What are the DNS records, and what are you expecting them to change your IP to, and how have you confirmed that the contents of the calls you're sending look like what you intended to send?

Also, what's going on with "&target[remote_addr]" in your request? Where is the delimiter separating the key from its value?

Thank you that was the issue. I missed the delimiter. Working great now.
