ntpq
queries the NTP daemon for status and configuration information
TLDR
SYNOPSIS
ntpq [options] [host...]
DESCRIPTION
ntpq queries the NTP daemon for status and configuration information. It can display peer associations, system variables, and synchronization statistics in both interactive and command-line modes.The peer list (-p) shows all configured time sources with columns indicating:- remote: Server address (* = current sync source)- refid: Reference clock or upstream server- st: Stratum level- reach: Reachability register (377 = all recent queries successful)- delay/offset/jitter: Timing metrics in millisecondsInteractive mode provides additional commands for detailed inspection of the NTP daemon's state.
PARAMETERS
-n, --numeric
Display addresses numerically without DNS resolution-c _command_, --command _command_
Execute a command without entering interactive mode-d, --debug-level
Enable debugging output-i, --interactive
Force interactive mode.-4, -6
Resolve hostnames using IPv4 or IPv6 only.-w, --wide
Use a wider peer table so long hostnames are not truncated.-k FILE, --keyfile FILE
Read symmetric keys from FILE for authenticated control requests.-a KEYID, --authentication KEYID
Use the given key id when sending authenticated queries.-p, --peers
Print a summary of all configured peers (same as interactive `peers`).-V, --version
Print version information and exit.
CAVEATS
Queries the local ntpd by default; specify a hostname to query remote daemons. Requires ntpd to be running. Some information may require authentication to access. The output format is cryptic; refer to NTP documentation for interpretation.
