NAME

6       ntpsweep - print various information about given NTP servers
7

SYNOPSIS

9       ntpsweep [-V | --version] [-l host]... [-p] [-m number] [-s prefix] [-h
10       string] [hostfile...]
11

DESCRIPTION

13       ntpsweep prints per host the NTP stratum level, the clock offset in
14       seconds, the daemon version, the operating system and the processor.
15       Optionally recursing through all peers.
16
17       If no hosts are specified, ntpsweep reports on localhost.
18
19       ntpsweep relies on ntpq and Mode 6 queries to probe servers. This
20       depends on the remote host’s restrict configuration allowing queries.
21       Nowadays effectively all public hosts set noquery, so this script is
22       unlikely to be useful unless you have multiple specially- configured
23       timeservers on a LAN.
24

OPTIONS

26       -l string, --host-list=string
27           Host to execute actions on. This option may appear an unlimited
28           number of times.
29
30           Use this option to specify the host on which this script operates.
31           May appear multiple times. Multiple hosts may be specified,
32           delimited by commas.
33
34       -p, --peers
35           Recursively list all peers a host synchronizes to.
36
37       -m number, --maxlevel=number
38           Traverse peers up to this level (4 is a reasonable number). This
39           option takes an integer number as its argument.
40
41       -s string, --strip=string
42           Strip this string from hostnames.
43
44       -h string, --host=string
45           Specify a single host. Deprecated option for backwards
46           compatibility.
47
48       -V, --version
49           Print the version string and exit.
50
51       If hostfiles are specified, they are treated as lists of hostnames to
52       be swept, one per line.
53

EXIT STATUS

55       One of the following exit values will be returned:
