Configure NTP

M1 Chassis

On the M1 server, with MK.IO Beam Contribution version 5.1 and above, it is recommended to configure NTP via the front panel or by using the “frontPanel” command line tool, as for the M2 chassis.

If your MK.IO Beam Contribution is hosted on an M1 server with a version lower than 5.1, NTP is configured directly on the server by editing the /etc/chrony.conf configuration file.

Add a line to point to the appropriate time server(s).

server 192.168.7.2 iburst

Check that the timeserver(s) can be reached with:

tracepath 192.168.7.2

Restart chronyd and sync quickly:

sudo systemctl restart chronyd 
sudo chronyc makestep

Check the status. Note that it may take a few minutes for the synchronization with the NTP server.

sudo chronyc ntpdata 
timedatectl

Additional debug:

sudo chronyc sources -v

M2 Chassis

If your MK.IO Beam Contribution is hosted on the M2 server, NTP is configured from the CE1 front panel or using the “frontPanel” command line tool.
