Syncing with NTP servers

Pexip Infinity uses NTP servers to obtain accurate system time. This is necessary to ensure correct operation, including configuration replication and log timestamps.

All host servers must be synchronized with accurate time before you install the Management Node or Conferencing Nodes on them.

NTP must be enabled on the Management Node VM before you deploy any Conferencing Nodes (this is done during installation of the Management Node).

We strongly recommend that you configure at least three distinct NTP servers or NTP server pools on all your host servers and the Management Node itself. This ensures that log entries from all nodes are properly synchronized.

The VMs hosting the Management Node and Conferencing Nodes use the UTC timezone, and all logs are in UTC. Do not attempt to change the timezone on these systems. Note however that the administrator web interface uses your local time. For more information, see Timezones.

To add, edit or delete the set of available NTP servers, go to System > NTP servers.

The available options are:

Option Description
Address The IP address or FQDN of the NTP server.
Description An optional description of the NTP server.
Secure NTP key ID This optional field allows you to configure a key ID which is used in conjunction with the Secure NTP key for authenticating access to a secure NTP server.
Secure NTP key This optional field, used in conjunction with the Secure NTP key ID, allows configuration of a SHA1 key for authenticating access to a secure NTP server. Enter the plaintext key; this will be stored as a SHA1 hash.

After configuring the NTP servers available to your system, you should assign appropriate NTP servers to each location (Platform > Locations). Each Conferencing Node in that location will then use those NTP servers.

You can also select the specific NTP servers to be used by the Management Node (Platform > Management Node).
