NTP needs some time so sync with other servers (even when using burst option). If your stratum is too low (16 = not synchronized) clients will refuse to take time from the server. How long have you waited? What does
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)
Hello Guys,

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?

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;
Code:

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?

ntptrace
ntptrace(8) System Manager's Manual ntptrace(8)NAME
ntptrace - trace a chain of NTP servers back to the primary source
SYNOPSIS
ntptrace [ -n ] [ -m maxhosts ] [ server ]
DESCRIPTION
ntptrace is a perl script that uses the ntpq utility program to follow the chain of NTP servers from a given host back to the primary time
source. For ntptrace to work properly, each of these servers must implement the NTP Control and Monitoring Protocol specified in RFC 1305
and enable NTP Mode 6 packets.
If given no arguments, ntptrace starts with localhost. Here is an example of the output from ntptrace:
% ntptrace
localhost: stratum 4, offset 0.0019529, synch distance 0.144135
server2ozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'
On each line, the fields are (left to right): the host name, the host stratum, the time offset between that host and the local host (as
measured by ntptrace; this is why it is not always zero for "localhost"), the host synchronization distance, and (only for stratum-1
servers) the reference clock ID. All times are given in seconds. Note that the stratum is the server hop count to the primary source, while
the synchronization distance is the estimated error relative to the primary source. These terms are precisely defined in RFC-1305.
OPTIONS -n Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.
BUGS
This program makes no attempt to improve accuracy by doing multiple samples.
