help [command_keyword]
A ? or help by itself will print a list of all the command keywords. ntpq.A? or
help followed by a command keyword (command_keyword) will print function and
usage information about the command.
delay milliseconds
Specify a time interval to be added to timestamps included in requests which require
authentication. This is used to enable (unreliable) server reconfiguration over long
delay network paths or between machines whose clocks are unsynchronized.
host hostname Set the host to which future queries will be sent. The hostname may be either a host
name or a numeric address.
hostnames [yes|no]
If yes is specified, host names are printed in information displays. If no is specified,
numeric addresses are printed instead. The default is yes, unless modified using the
command line -n command.
keyid keyid This command allows the specification of a key number to be used to authenticate
configuration requests. The keyid must correspond to a key number that the server
has been configured to use for this purpose.
quit Exit xntpdc.
passwd This command prompts you to type in a password (which will not be echoed) which
will be used to authenticate configuration requests. The password must correspond to
the key configured for use by the NTP server for this purpose if such requests are to
be successful.
timeout milliseconds
Specify a timeout period for responses to server queries. The default is about 8000
milliseconds. Note that since xntpdc retries each query once after a timeout, the
total waiting time for a timeout will be twice the timeout value set.
CONTROL MESSAGE COMMANDS
Query commands result in NTP mode 7 packets containing requests for information being sent to the
server. These are read-only commands in that they make no modification of the server configuration state.
listpeers Obtains and prints a brief list of the peers for which the server is maintaining state.
This list should include all configured peer associations as well as those peers whose
stratum is such that they are considered by the server to be possible future synchroni-
zation candidates.
peers Obtains a list of peers for which the server is maintaining state, along with a sum-
mary of that state. Summary information includes the address of the remote peer, the
local interface address (0.0.0.0 if a local address has yet to be determined), the stra-
tum of the remote peer (a stratum of 16 indicates the remote peer is unsynchronized),
the polling interval in seconds, the reachability register in octal, and the current
estimated delay, offset and dispersion of the peer, all in seconds. In addition, the char-
acter in the left margin indicates the mode this peer entry is operating in.
+ indicates symmetric active
- indicates symmetric passive
= indicates the remote server is being polled in client mode
^ indicates the server is broadcasting to this address
~ indicates the remote peer is sending broadcasts
* indicates the peer that the server is currently synchronizing to.
The contents of the host field may be a host name, an IP address, a reference clock implementation
name with its parameter or REFCLK (implementation number, parameter). For hostnames no,
only IP addresses will be displayed.
dmpeers
A slightly different peer summary list. The output is similar to that of the
peers command,
except for the character in the leftmost column. Characters only appear beside peers which were
included in the final stage of the clock selection algorithm. A period (
.) indicates that this peer
