NTP Settings Panel

NTP setting panel is a protocol designed to synchronize the host machine clocks over a network. For more information on NTP see the home page (http://www.ntp.org/).

Note: NetWitness core hosts must be able to communicate with the NetWitness Server host with UDP port 123 for NTP time synchronization.

You use the netwitness_adminicon_25x22.png (Admin) > System > NTP Settings view to configure one or more NTP servers. After you configure an NTP server, NetWitness uses NTP to synchronize the host machine clocks. You configure multiple NTP servers for Fail Over purposes.
