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?
Thank you.

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.

Hi folks,
The server time is no tgetiing synched up with the NTP server.
I tried ntpdate -u <ipadress> this is not working. please help out.

Hello all,
What would be the most convienint and proper way on syncing up the time and date on Solaris 8 servers with an NTP server?
Any help would be appreciated. Thanks (2 Replies)
All,
I need to write a script which can determine if my NTP client is X second off from the NTPD server time. I am looking for a crafty oneliner to calculate the time difference? (3 Replies)
I need to configure an NTP daemon on a "bridge-PC" connected on 2 LANs. It is expected to read the correct time on a time server on the first LAN and behave as a server for the second LAN.
Can I do both the things with ntpd?
In other words, is ntpd able to work as client and server at the same... (3 Replies)
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)
Hi
I am looking to have an NTP server that will support both ipv4 and ipv6 clients. Is there anything specific about the configuration that I should be looking at? (7 Replies)
Hi folks, I have developed a Linux server for my customer. After migrating the server to my customer site, I was trying to sync its time to the NTP time servers at my customer site.
Below is the ntp.conf:

We had a network problem a couple of days before that caused 1 interface to down and up. But today I have noticed that our date is wrong, our system have 4 servers and the other 3 are OK.
I used <date> command, the result is: Fri Jan 2 17:57:55 ICT 1970
I have tried set date to be the same as... (3 Replies)

tnm::ntp
ntp(n) Tnm Tcl Extension ntp(n)
__________________________________________________________________________________________________________________________________________________NAME
ntp - Retrieve NTP status information.
_________________________________________________________________DESCRIPTION
The Network Time Protocol (NTP) (RFC 1119, RFC 1305) allows to synchronize computer clocks by exchanging NTP messages. The ntp command
allows to retrieve control variables from NTP peers.
NTP COMMAND
ntp [options]
Invoking the ntp command with options but without any command arguments allows to retrieve and change the default values. See the
description of supported options below. Default values are bound to a Tcl interpreter which allows to have multiple Tcl interpreter
with different defaults.
ntp [options] host arrayName
The ntp command sends a NTP version 3 mode 6 request to host and writes status information into the Tcl array arrayName. After suc-
cessful completion, the array will contain the following elements (RFC 1305):
peer.delay
This is a signed fixed-point number indicating the roundtrip delay of the peer clock relative to the local clock over the
network path between them, in seconds.
peer.dispersion
This is a signed fixed-point number indicating the maximum error of the peer clock relative to the local clock over the net-
work path between them, in seconds.
peer.offset
This is a signed, fixed-point number indicating the offset of the peer clock relative to the local clock, in seconds.
peer.precision
This is a signed integer indicating the precision of the various clocks, in seconds to the nearest power of two.
peer.reach
This is a shift register used to determine the reachability status of the peer, with bits entering from the least significant
(rightmost) end. A peer is considered reachable if at least one bit in this register is set to one.
peer.srcadr
This is the IP address of the peer.
peer.stratum
This is an integer indicating the stratum of the local clock.
peer.valid
This is an integer counter indicating the valid samples remaining in the filter register. It is used to determine the reacha-
bility state and when the poll interval should be increased or decreased.
sys.peer
This is a selector identifying the current synchronization source.
sys.precision
This is a signed integer indicating the precision of the various clocks, in seconds to the nearest power of two.
sys.refid
This is a 32-bit code identifying the particular reference clock.
sys.rootdelay
This is a signed fixed-point number indicating the total roundtrip delay to the primary reference source at the root of the
synchronization subnet, in seconds.
sys.rootdispersion
This is a signed fixed-point number indicating the maximum error relative to the primary reference source at the root of the
synchronization subnet, in seconds.
sys.stratum
This is an integer indicating the stratum of the local clock
sys.system
A textual description of the system type.
NTP OPTIONS
The following options control how NTP requests are send and how the ntp command deals with lost NTP packets.
-timeout time
The -timeout option defines the time the ntp command will wait for a response. The time is defined in seconds with a default of 2
seconds.
-retries number
The -retries option defines how many times a request is retransmitted during the timeout interval. The default number of retries is
2.
