Fixed In Version: ntp-4.2.6p5-3.el6
Doc Type: Bug Fix
Doc Text:
Previously, the ntpd daemon included a root delay when calculating its root dispersion. Consequently, the NTP server reported larger root dispersion that it should have and clients could reject the source when its distance reached the maximum synchronization distance (1.5 seconds by default). Calculation of root dispersion has been fixed, the root dispersion is now reported correctly, and clients no longer reject the server due to large synchronization distance.
