drop script 'rotate-ntp'
For RouterOS 6.x a separate package 'ntp' exists. This adds server functionality, but allows ip addresses for the client only. I added the script 'rotate-ntp' to update addresses from names... Now with RouterOS 7.x there's no extra package and the limitation does no longer exist. So let's just drop the script. This adds migration code, that... * removes the script from configuration * removes a scheduler from configuration * sets the configured ntp pool name for ntp client

Rotate NTP servers
|
||||
==================
|
||||
|
||||
[◀ Go back to main README](../README.md)
|
||||
|
||||
> ℹ️ **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;
|
||||

||||

||||

|
||||
[▲ Go back to top](#top)
|
||||
This script has been dropped as the limitation does no longer exist with
|
||||
RouterOS 7.x, where you can enable a ntp server and use a name for the client
|
||||
at the same time.
