This works for me.
Thanks a lot. Anonymous Posted March 5, 0 Comments. However, a preferred time source will be used only if it falls within a certain window of accuracy determined by your NTP daemon.
For such a client, the server lines shown above are not used. Instead, a single line is used in the ntp. This line, included in the ntp. To use NTP in multicast mode, you need to provide a multicast server. While this isn't necessarily difficult, many more options exist for defining NTP servers and a bit more work must be done to get even the most basic server running.
Once configured as a broadcast or multicast server, an NTP server daemon will issue periodic time updates to its broadcast or multicast clients. To understand how this works, let's take a closer look at the ntp.
The top 50 lines or so of this prototype file are comments that provide information on the syntax of the operative lines. The most important line of this file is the server line. The initial server line will look like this:.
If you want to set up NTP for synchronization purposes only and are unconcerned with whether or not the system clocks are accurate with respect to the atomic clocks, you can configure this line to look like this:. The third octet in this IP address, the "1", indicates that you are electing to use a reference clock driver of type "undisciplined local clock".
This simply means your system clock. This setting is intended for isolated networks where no external source of synchronization is available. The NTP clients using this server for time information should use the multicastclient keyword as shown below. If you want your NTP server to obtain time updates from external servers, add server lines like these the same as those shown earlier in the column :.
By deriving accurate time from highly accurate i. To check the status of the time synchronisation, use the ntpq utility. Let run for about 6 minutes before continuing, Otherwise stratum will show NB 6 minutes is the best case — if a deamon is significantly out of sync, then may take several times longer. Now the client can be configured. For australia: AU ntp. Let the daemon run for 6 miuntes before proceeding to the next step — or may get stratum 16 error.
Problem: NTP daemon dies almost right after it is started. May log error in errpt -a. Solutions: 1. Check the date on the machine. Check the TZ variable. Often a timezone variable on the client that is different than the server can cause this problem. Kindly help. Best Regards, Santosh. What is the secret? Adapter Virt. For this you must configure ntp. Translation: You want ntpd, you need to configure ntp. You CAN use ntpdate to do manual updates.
Date change: 1. If the server is "insane": 2. Enter the following:startsrc -s xntpd -a "-x" 3. If the offset is greater than seconds, change the time manually on the client and run the ntpdate -d again. If you get the message, "no server suitable for synchronization found", verify xntpd is running on the server see above and that no firewalls are blocking port Leave the driftfile and tracefile at their defaults.
