Rotate NTP servers
==================
[◀ Go back to main README](../README.md)
> **Info**: This script can not be used on its own but requires the base
> installation. See [main README](../README.md) for details.
Description
-----------
RouterOS requires NTP servers to be configured by IP address. Servers from a
pool may appear and disappear, leaving broken NTP configuration.
This script allows to rotate IP addresses from a given pool.
Requirements and installation
-----------------------------
Just install the script:
$ScriptInstallUpdate rotate-ntp;
Configuration
-------------
The configuration goes to `global-config-overlay`, this is the parameter:
* `NtpPool`: dns name of ntp server pool
Usage and invocation
--------------------
Just run the script to update the NTP configuration with actual IP
addresses from pool if required.
Alternatively a scheduler can be created:
/system/scheduler/add interval=5d name=rotate-ntp on-event="/system/script/run rotate-ntp;" start-time=startup;
