3. Synopsis
ntpsweep [-V | --version] [-l host]… [-p] [-m number] [-s prefix] [-h string] [hostfile…]
4. Description
ntpsweep prints per host the NTP stratum level, the clock offset in
seconds, the daemon version, the operating system and the processor.
Optionally recursing through all peers.
If no hosts are specified, ntpsweep reports on localhost.
ntpsweep relies on ntpq and Mode 6 queries to probe servers. This
depends on the remote host’s restrict configuration allowing
queries. Nowadays effectively all public hosts set noquery, so this
script is unlikely to be useful unless you have multiple specially-
configured timeservers on a LAN.
5. Options
-lstring,--host-list=string-
Host to execute actions on. This option may appear an unlimited number of times.
Use this option to specify the host on which this script operates. May appear multiple times. Multiple hosts may be specified, delimited by commas.
-p,--peers-
Recursively list all peers a host synchronizes to.
-mnumber,--maxlevel=number-
Traverse peers up to this level (4 is a reasonable number). This option takes an integer number as its argument.
-sstring,--strip=string-
Strip this string from hostnames.
-hstring,--host=string-
Specify a single host. Deprecated option for backwards compatibility.
-V,--version-
Print the version string and exit.
If hostfiles are specified, they are treated as lists of hostnames to be swept, one per line.
