About

ntpMerlin implements an NTP time server for AsusWRT Merlin with charts for daily, weekly and monthly summaries of performance. A choice between ntpd and chrony is available.

ntpMerlin is free to use under the GNU General Public License version 3 (GPL 3.0).

Supported firmware versions

You must be running firmware Merlin 384.15/384.13_4 or Fork 43E5 (or later) Asuswrt-Merlin

Installation

Using your preferred SSH client/terminal, copy and paste the following command, then press Enter:

/usr/sbin/curl --retry 3 "https://raw.githubusercontent.com/AMTM-OSR/ntpMerlin/master/ntpmerlin.sh" -o "/jffs/scripts/ntpmerlin" && chmod 0755 /jffs/scripts/ntpmerlin && /jffs/scripts/ntpmerlin install

Prerequisites

1. Asuswrt-Merlin running on a supported ASUS router
2. Entware installed, preferably using amtm
3. jffs scripts enabled in the firmware; this can be set manually, and installing Entware via amtm usually takes care of it

Usage

ntpMerlin can be configured via the WebUI, in the Addons section.

Command Line

To launch the ntpMerlin menu after installation, use:

ntpmerlin

If this does not work, you will need to use the full path:
