ntpd does not handle the SIGHUP signal. This means when ntpd receives HUP, it is terminated. The ntpd script might wrap the ntpd call in a while loop, so that it restarts the daemon after HUP is received.
At any rate, there's no way to reload the ntpd daemon without restarting it.

NTP home page for more info.

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.

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.

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?

ntp-wait(1) User Commands ntp-wait(1)
NAME
ntp-wait - Wait for ntpd to stabilize the system clock
SYNOPSIS
ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]]
All arguments must be options.
DESCRIPTION
ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not
yet produced a synchronized and stable system clock.
ntp-wait will do this quietly, unless the -v flag is provided. This can be useful at boot time, to delay the boot sequence until after
ntpd -g has set the time.
OPTIONS
-n number, --tries=number
Number of times to check ntpd. This option takes an integer number as its argument. The default number for this option is:
100
The maximum number of times we will check ntpd to see if
it has been able to synchronize and stabilize the system clock.
-s secs-between-tries, --sleep=secs-between-tries
How long to sleep between tries. This option takes an integer number as its argument. The default secs-between-tries for this
option is:
6
We will sleep for secs-between-tries after each query
of ntpd that returns "the time is not yet stable".
-v, --verbose
Be verbose.
By default, ntp-wait is silent.
With this option, ntp-wait will provide status information.
-?, --help
Display usage information and exit.
-!, --more-help
Pass the extended usage information through a pager.
-v [{v|c|n --version [{v|c|n}]}]
Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and
`n' will print the full copyright notice.
EXIT STATUS
One of the following exit values will be returned:
0 (EXIT_SUCCESS)
Successful program execution.
1 (EXIT_FAILURE)
The operation failed or the command syntax was not valid.
70 (EX_SOFTWARE)
libopts had an internal operational error. Please report it to autogen-users@lists.sourceforge.net. Thank you.
