12.8 NTP Utilities
• lopeers
Obtains and displays a list of all peers and clients having the destination
address.
•
lpassociations
Displays data for all associations, including unrecognized client associations,
from the internally cached list of associations.
• lpeers
Similar to peers except that a summary of all associations for which the
server is maintaining state is displayed. This command can produce a much
longer list of peers.
• mreadlist assocID assocID
Similar to the readlist command except that the query is done for each
of a range of (nonzero) association IDs. This range is determined from the
association list cached by the most recent associations command.
• mreadvar assocID assocID [variable_name[=value] [,...] ]
Similar to the readvar command except that the query is done for each of
a range of (nonzero) association IDs. This range is determined from the
association list cached by the most recent
associations command.
• opeers
An old form of the peers command, with the reference ID replaced by the
local interface address.
• passociations
Displays association data concerning recognized peers from the internally
cached list of associations. This command performs identically to the
associations command except that it displays the internally stored data
rather than make a new query.
• peers
Displays a list of recognized peers of the server, along with a summary of
each peer’s state. Summary information includes the address of the remote
peer; the reference ID (0.0.0.0 if the reference ID is unknown); the stratum of
the remote peer; the polling interval (in seconds); the reachability register (in
octal); and the current estimated delay, offset, and dispersion of the peer (in
milliseconds).
The character in the left margin indicates the fate of this peer in the clock
selection process. The codes are as follows:
Space indicates that the peer was discarded, because of high stratum or
failed sanity checks.
Lowercase x indicates that the peer was designated a falseticker by the
intersection algorithm.
Dot (.) indicates that this peer was culled from the end of the candidate
list.
Hyphen (-) indicates that the peer was discarded by the clustering
algorithm.
Plus sign (+) indicates that the peer was included in the final selection
set.
Pound sign (#) indicates that the peer was selected for synchronization,
but the distance exceeds the maximum.
Asterisk (*) indicates that the peer was selected for synchronization.
