Hello, I'm trying to create a NTP server on a FreeBSD machine inside my local network, so all the clients of that network can actually query for that machine.
Should be of no problem right?
Here's the configuration of the /etc/ntp.conf on the FreeBSD machine:
It should get the time from br.pool.ntp.org, and restrict everything besides the local network right?
Here's the output of a linux machine when I try to execute
Code:
ntpdate -d -t 60 10.100.0.1

Hi.
i was wondering if anyone can show me or direct me on setting up a ntp server under redhat.. Is there any howtos so i can get familar to it "any good sites" (3 Replies)
All,
How do you set a Solaris 9 server which received ntp updates from a ntp server to broadcast them on a local subnet. I have created a /etc/inet/ntp.conf file to receive the updates from a server on network and need to make this server become like a ntp relay from the main server.
Any... (1 Reply)

Hi All....
I need to configure NTP server in my network, which is heterogeneous, containing Linux as well as windows systems. I'm planning to configure it on RHEL 5.0. What are the prerequisites for this and do I need to register this server?
Can anyone give me as many information as... (1 Reply)
All here, thank you for listening. Now I've set up a Linux NTP server by adding a external windows NTP server in /etc/ntp.conf. Then I start the ntpd daemon. But how often does the Linux NTP server update its time with the external NTP server? I've looked up everywhere but found no information... (1 Reply)
hello Guys,
I have an NTP problem on my SUN N240 server. External NTP server is being used for this box and when i run 'ntpq -p' i get connection refused message;

Hi,
I have two ntp servers in my cluster and I want all the nodes in my cluster to sync with either of the ntp servers or just one. Unfortunately it keep rotating the sync, between my ntp server 1, ntp server 2 and local. Is there anyway I can change the sync to avoid local?

timesyncd.conf
TIMESYNCD.CONF(5) timesyncd.conf TIMESYNCD.CONF(5)NAME
timesyncd.conf, timesyncd.conf.d - Network Time Synchronization configuration files
SYNOPSIS
/etc/systemd/timesyncd.conf
/etc/systemd/timesyncd.conf.d/*.conf
/run/systemd/timesyncd.conf.d/*.conf
/usr/lib/systemd/timesyncd.conf.d/*.conf
DESCRIPTION
These configuration files control NTP network time synchronization.
CONFIGURATION DIRECTORIES AND PRECEDENCE
The default configuration is defined during compilation, so a configuration file is only needed when it is necessary to deviate from those
defaults. By default, the configuration file in /etc/systemd/ contains commented out entries showing the defaults as a guide to the
administrator. This file can be edited to create local overrides.
When packages need to customize the configuration, they can install configuration snippets in /usr/lib/systemd/*.conf.d/. Files in /etc/
are reserved for the local administrator, who may use this logic to override the configuration files installed by vendor packages. The main
configuration file is read before any of the configuration directories, and has the lowest precedence; entries in a file in any
configuration directory override entries in the single configuration file. Files in the *.conf.d/ configuration subdirectories are sorted
by their filename in lexicographic order, regardless of which of the subdirectories they reside in. When multiple files specify the same
option, for options which accept just a single value, the entry in the file with the lexicographically latest name takes precedence. For
options which accept a list of values, entries are collected as they occur in files sorted lexicographically. It is recommended to prefix
all filenames in those subdirectories with a two-digit number and a dash, to simplify the ordering of the files.
To disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null in the configuration
directory in /etc/, with the same filename as the vendor configuration file.
OPTIONS
The following settings are configured in the "[Time]" section:
NTP=
A space-separated list of NTP server host names or IP addresses. During runtime this list is combined with any per-interface NTP
servers acquired from systemd-networkd.service(8). systemd-timesyncd will contact all configured system or per-interface servers in
turn until one is found that responds. When the empty string is assigned, the list of NTP servers is reset, and all assignments prior
to this one will have no effect. This setting defaults to an empty list.
FallbackNTP=
A space-separated list of NTP server host names or IP addresses to be used as the fallback NTP servers. Any per-interface NTP servers
obtained from systemd-networkd.service(8) take precedence over this setting, as do any servers set via NTP= above. This setting is
hence only used if no other NTP server information is known. When the empty string is assigned, the list of NTP servers is reset, and
all assignments prior to this one will have no effect. If this option is not given, a compiled-in list of NTP servers is used instead.
RootDistanceMaxSec=
Maximum acceptable root distance. Takes a time value (in seconds). Defaults to 5 seconds.
PollIntervalMinSec=, PollIntervalMaxSec=
The minimum and maximum poll intervals for NTP messages. Each setting takes a time value (in seconds). PollIntervalMinSec= must not be
smaller than 16 seconds. PollIntervalMaxSec= must be larger than PollIntervalMinSec=. PollIntervalMinSec= defaults to 32 seconds, and
PollIntervalMaxSec= defaults to 2048 seconds.
