DNS update Cpanel

Question

I’m trying to use a script to update the IP of our server, to be able to access externally since we use dynamic IP.

The script what use is [that][1]:

But it returns me the following error :

<?php
// Based on the hard work of Mitchel Haan

//
// usage:
// http://username:[email protected]/dyndns.php?hostname=remote&myip=192.168.1.1
//
// per the settings below, the above will update the IP remote.example.com to 192.168.1.1
// myip is not required, will default to the remote IP calling the script

// most dyndns clients will work with a custom url setting. you will likely need to only

--> line: 199 No hosts found

Someone’s used it and can give me a light?

Answer 1

"No hosts found" means the script did not find in the domain specified by the variable $dyndnsRemoteHostDomain the host you specified on the command line.

If you run the script with the following URL:

http://username:[email protected]/dyndns.php?hostname=remote

The host remote.website.com must already exist. The script does not create it for you.

NOTE: I am considering that you are obviously not using "this" script, but a particular version of it. Without your particular data "this" script does not work.
