ntpserver

The ntpd package is already installed by default on WAGO (linux based) controller, in order to work as a NTP client.

Enable NTP server only once

To enable the NTP server on a WAGO Controller you can use the following command :

ntpd -l

You can see the NTP request by using the packet capture tool tcpdump

tcpdump port 123

To start the daemon at the controller startup, download the ntpserver script in the repo in /etc/init.d/ntpserver

Give it execution permission :

chmod 750 /etc/init.d/ntpserver

Add a symlink in /etc/rc.d :

ln -s /etc/init.d/ntpserver /etc/rc.d/S99_ntpserver

Disable the service

/etc/init.d/ntpserver stop

Disable daemon start at bootup

rm /etc/rc.d/S99_ntpserver

A package file is provided here to easily start the server, install the /etc/init.d/ntpserver script, and the symlink in /etc/rc.d/

You can install in command line using

opkg install -V3 ntpserver_v1.0.0_armhf.ipk

You can also install it using the Web Based Management and upload the file in Conofiguration / Software Upload.

You can remove it in command line using

opkg remove -V3 ntpserver_v1.0.0_armhf.ipk
