NTP Authentication

Version History

ReleaseModification
5.6.0NTP Authentication introduced

Support for NTP authentication allows external NTP servers to be authenticated using an md5 or sha1 hash, allowing the SSR to verify the identity of the server being used for NTP time synchronization.

To allow the NTP client to synchronize with an authenticated server the following information must be provided:

  • Server ip-address: This is required.
  • Key-number: The specific number used by the server to identify the key. Range is 1-65534. The number configured on the device must match the key number expected by the server.
  • Authentication type: Either md5 or sha1 (recomended)
  • Shared key from the server: 20 characters long for md5. 40 characters long for sha1.

Example config:

                    authority
name Authority128
router Fabric128
name Fabric128
system
ntp
server 1.1.1.1
