This script is intended to be used for the Securepoint Dynamic DNS Service (https://www.spdyn.de/).
The script tries to contact the service only if necessary to avoid a ban due a high request count. But because of it's router independent pre check function you can execute it every 5 minutes with the Windows Task Scheduler without any risks.
Due to the extended security restrictions of PowerShell scripts the easiest way is to copy & paste the code.
- open Powershell ISE
- paste the code
- adjust your values
- save it as a *.ps1 file
- execute the script
$fqdn Your fully qualified domain name, e.g. home.spdns.de
$user Your username at spdns.de
$pwd Your password at spdns.de
$dnsserver Specify an external DNS Server to avoid DNS caching
This script has an optional logging function for simple debugging purposes. Change $logging = $true to enable it.
Ensure proper write permissions in the given folder structure. The log file itself will be created if missing.
Q: I get a ...execution of scripts is disabled on this system. error when executing the script. What can I do?
A: Open PowerShell as administrator paste set-executionpolicy remotesigned and confirm it.
Q: Does the script work with tokens?
A: Yes. A token is nothing else but an password that only works with the desired FQDN. Note: When you generate a token $user MUST be equal to your FQDN!
