My display is reaching out to unknown NTP servers instead of Daktronics.pool.ntp.org

Potential Symptoms

  • My display is reaching out to unknown NTP servers instead of 0.daktronics.pool.ntp.org, 1.daktronics.pool.ntp.org, 2.daktronics.pool.ntp.org, or 3.daktronics.pool.ntp.org.
  • I am seeing the VIP connect to unknown IP addresses or hosts using ntp-udp services when monitoring my network traffic.

Environment

  • Product Family: Message Displays, Billboards
  • Product: GS6
  • Component: DMP-5060
  • Control System: Venus Control Suite, Visiconn, Venus 1500

Cause

  • In addition to [0,1,2,3].daktronics.pool.ntp.org, the DMP-5000's are sent out configured to ntp.ubuntu.com. Since this is a NTP Pool it is attempting to reach out to multiple public NTP services.

Resolution

  • Remove ntp.ubuntu.com from the DMP's web config time page or allow it on the network.
