Field Descriptions
The following section describes the fields displayed using the ntppstat command.
remote host. The IP address of the host whose statistics you are viewing.
local interface. The local interface address assigned by NTP to the remote association. If this
address is 0.0.0.0, then the local address has yet to be determined.
time last received. The number of seconds since the last NTP message packet was received
from another NTP entity in the network.
time until next send. The number of seconds until this NTP peer sends out an NTP message
packet.
reachability change. This field displays the number of times this client/server’s reachability has
changed.
packets sent. The number of NTP message packets this peer has sent out.
packets received. The number of NTP message packets this peer has received.
bad authentication. The number NTP message packets this peer has rejected due to failed
authentication.
bogus origin. The number of times a response packet from another NTP entity doesn’t match
the request packet sent out by this client/server.
duplicate. The number of identical NTP message packets this peer has received.
bad dispersion. The number of packets that were discarded due to overly large error disper-
sions.
bad reference time. The number of packets that were discarded because the contained refer-
ence time didn’t match the local peer expectation.
candidate order. A number that represents this client/server’s synchronization order. A lower
number represents a reliable synchronization source.
