You can use [code] tags to make your output formatted like the terminal output. The NTP daemon is usually packaged with several README files in HTML format. If not, Google turned up the top link: http://www.ntp.org/documentation.html
"st" is "stratum" -- the lower, the more authoritative. "remote" is obviously the name of the NTP server the rest of the line refers to. "refid" is complicated to explain. "poll" is how often the NTP sever in question is asked about the time. "when" means how many more seconds until the poll time is reached (or how many seconds ago it was last reached). "reach" means whether the site in question is reachable -- zero means it isn't; the others are various metrics used by NTP to calculate the actual time. The "offset" means how much the remote server's clock differs from the local clock. The "delay" means how many tics it takes for a packet from "there" to reach "here", which is important in determining how to interpret offset. Not sure what "disp" is, but often you see "jitter" which means how consistent the delay values is. So the real time is something like:
but I doubt it's that simple.

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 All,
Where can I find all the NTP server names/ip addresses on Linux/Solaris systems. How can I grep these names/IP address from specific files from a specific OS (Linux/Solaris).
I know on linux /etc/ntp.conf and /etc/ntp/ntp.conf on solaris contains these details. Whether I am right about... (4 Replies)

ntp.drift
ntp.drift(4) Kernel Interfaces Manual ntp.drift(4)NAME
ntp.drift - Network Time Protocol (NTP) drift file
DESCRIPTION
When the NTP daemon (xntpd) is first started, it computes the error in the intrinsic frequency of the clock on the computer it is running
on. This process usually takes about a day or two after the daemon is started to compute a good estimate of this (and it needs a good
estimate to synchronize closely to its server). Once the initial value is computed, it will change only by relatively small amounts during
the course of continued operation.
The driftfile declaration should always be included in the ntp.conf file. This provides xntpd with complete path name to a file in which
it can store the current value of the frequency error. That way, if the daemon is stopped and restarted, it can reinitialize itself to the
previous estimate without spending time recomputing the frequency estimate.
The ntp.drift file contains one line with the following format: freq_offset flag Specifies the nominal frequency offset. DO NOT modify
this field. Specifies the method used to improve system clock accuracy. Specifies that xntpd runs a Phase-Locked Loop (PLL) algorithm to
keep synchronized with other hosts. This is the default. Specifies the use of the PLL algorithm in the kernel. This requires the
NTP_TIME kernel option. After the option is configured in the kernel, edit the ntp.drift file and change the flag value to 1.
See System Administration for information on the NTP_TIME kernel option.
