Rotate NTP servers

◀ Go back to main README

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;
