NTP

Wazo has a NTP server, that must be synchronized to a reference server. This can be a public one or customized for specific target networking architecture. Wazo's NTP server is used by default as NTP server for the devices time reference.

Usage​

Show NTP service status:

service ntp status

Stop NTP service:

service ntp stop

Start NTP service:

service ntp start

Restart NTP service:

service ntp restart

Show NTP synchronization status:

ntpq -p

Configuring NTP service​

  1. Edit /etc/ntp.conf

  2. Give your NTP reference servers:

    server 192.168.0.1                           # LAN existing NTP Server
    server 0.debian.pool.ntp.org iburst dynamic  # default in ntp.conf
    server 1.debian.pool.ntp.org iburst dynamic  # default in ntp.conf

  3. If no reference server to synchronize to, add this to synchronize locally:

    server 127.127.1.0              # local clock (LCL)
    fudge 127.127.1.0 stratum 10    # LCL is not very reliable

  4. Restart NTP service

  5. Check NTP synchronization status.

Warning: If #5 shows that NTP doesn't use NTP configuration in /etc/ntp.conf, maybe have you done a dhclient for one of your network interface and the dhcp server that gave the IP address also gave a NTP server address. Thus you might check if the file /var/lib/ntp/ntp.conf.dhcp exists, if yes, this is used for NTP configuration prior to /etc/ntp.conf. Remove it and restart NTP, check NTP synchronization status, then it should work.
