This repository contains a service that syncs resources from different entities. All entities must publish their Timestamp and also be capable to set a delay at one sampling period. This service will only work if the clock of all computer nodes are synced. For that we recommend using chrony - a versatile implementation of the Network Time Protocol (NTP).
- Install chrony on all computer nodes:
$ sudo apt install chrony-
Choose one node to be the reference (i.e 10.60.0.3)
-
On the reference node add allow 0/0 in /etc/chrony/chrony.conf to allow any user to connect to the server:
+ allow 0/0- On other nodes edit /etc/chrony/chrony.conf and remove all lines that start with pool and add one with our reference node:
- pool 2.debian.pool.ntp.org offline iburst
+ pool 10.60.0.3 iburst- Restart chrony on every node:
$ sudo service chrony restart- Check the synchronism by running:
$ sudo chronyc sources
210 Number of sources = 1
