Installation

As root, use the make install command to install the binaries in the destination directory. Most commonly, these programs are installed in /usr/local/bin, but this can be overridden during configuration. You must of course have write permission on the install in the destination directory. This includes the following programs:

If the precision time kernel modifications are present, the following program is installed:

If the public key authentication functions are present, the following program is installed:

In some systems that include the capability to edit kernel variables, the following program is installed:

Cryptographic support, both symmetric and public key, requires one or more key files, commonly installed in /usr/local/etc. Public key cryptography requires a random seed file, usually called .rnd, installed in a dark place such as the root directory or /etc. Directions for generating keys is on the Authentication Options page.

Configuration

You are now ready to configure the daemon and start it. You will need to create a NTP configuration file ntp.conf and a cryptographic key file ntp.keys. The latter file is necessary only for remote configuration support, if needed. Newbies should see the Quick Start page for orientation. Seasoned veterans can start with the ntpd - Network Time Protocol (NTP) daemon page and move on to the specific configuration option pages from there. A tutorial on NTP subnet design and configuration options is in the Notes on Configuring NTP and Setting up a NTP Subnet page.

If You Have Problems

If you have problems peculiar to the particular hardware and software environment (e.g. operating system-specific issues), browse the Hints and Kinks page. For other problems a tutorial on debugging technique is in the NTP Debugging Technique page. As always, the first line of general assistance is the NTP web site www.ntp.org and the FAQ resident there. Requests for assistance of a general nature and of interest to other timekeepers should be sent to the NTP newsgroup comp.protocols.time.ntp. Bug reports of a specific nature should be sent to bugs@ntp.org. Bug reports of a specific nature on features implemented by the programmer corps mentioned in the Copyright page should be sent directly to the implementor listed in that page, with copy to bugs@ntp.org.

Please include the version of the source distribution (e.g., ntp-4.0.70a) in your bug report, as well as billboards from the relevant utility programs and debug trace, if available. Please include the output of config.guess in your bug report. It will look something like:

pdp11-dec-fuzzos3.4

This is an index for a set of troubleshooting notes contained in individual text files in the ./hints directory. They were supplied by various volunteers in the form of mail messages, patches or just plain word of mouth. Each note applies to a specific computer and operating system and gives information found useful in setting up the NTP distribution or site configuration. The notes are very informal and subject to errors; no attempt has been made to verify the accuracy of the information contained in them.

A distribution so widely used as this one eventually develops numerous barnacles as the result of porting to new systems, idiosyncratic new features and just plain bugs. In order to help keep order and make maintenance bearable, we ask that proposed changes to the distribution be submitted in the following form.

Please avoid patching the RCS subdirectories; better yet, clean them out before submitting patches.
If you have whole new files, as well as patches, wrap the files and patches in a shell script. If you need to compress it, use either GNU gzip or the stock Unix compress utility.
Don't forget the documentation that may be affected by the patch. Send us patches for the ./htm files as well. -

We would be glad to include your name, electric address and descriptive phrase in the Copyright page, if you wish.
Prior to ntp3-5.83 (releases up to and including ntp3.5f) a complete patch history back to the dark ages was kept in the ./patches directory, which might have been helpful to see if the same problem occurred in another port, etc. Patches were saved in that directory with file name in the form patch.nnn, where nnn was approaching 200. All patches in that directory have been made; so, if yours was there, it was in the distribution.

Since we have been getting multple patches for some bugs, plus many changes are implemented locally, no two maintainers here use the same tools, and since we're not using any bug-tracking software or even source code control, there is currently no tracking of specific changes.

For the rank amateur the sheer volume of the documentation collection must be intimidating. However, it doesn't take much to fly the ntpd daemon with a simple configuration where a workstation needs to synchronize to some server elsewhere in the Internet. The first thing that needs to be done is to build the distribution for the particular workstation and install in the usual place. The Building and Installing the Distribution page describes how to do this.

While it is possible that certain configurations do not need a configuration file, most do require one. The file, called by default /etc/ntp.conf, need only contain one line specifying a remote server, for instance

server foo.bar.com
-
Choosing an appropriate remote server is somewhat of a black art, but a suboptimal choice is seldom a problem. There are about two dozen public time servers operated by National Institutes of Science and Technology (NIST), US Naval Observatory (USNO), Canadian Metrology Centre (CMC) and many others available on the Internet. Lists of public primary and secondary NTP servers maintained on the Public NTP TIme Servers page, which is updated frequently.The lists are sorted by country and, in the case of the US, by state. Usually, the best choice is the nearest in geographical terms, but the terms of engagement specified in each list entry should be carefully respected.

Usually, the best choice is the nearest in geographical terms, but the terms of engagement specified in each list entry should be carefully respected.

During operation ntpd measures and corrects for incidental clock frequency error and writes the current value to a file called by default /etc/ntp.drift. If ntpd is stopped and restarted, it initializes the frequency from this file. In this way the potentially lengthy interval to relearn the frequency error is avoided.

That's all there is to it, unless some problem in network connectivity or local operating system configuration occurs. The most common problem is some firewall between the workstation and server. System administrators should understand NTP uses UDP port 123 as both the source and destination port and that NTP does not involve any operating system interaction other than to set the system clock. While almost all modern Unix systems have included NTP and UDP port 123 defined in the services file, this should be checked if ntpd fails to come up at all.
-
The best way to confirm NTP is working is using the ntpq utility, although the ntpdc utility may be useful in extreme cases. See the documentation pages for further information. In the most extreme cases the -d option on the ntpd command line results in a blow-by-blow trace of the daemon operations. While the trace output can be cryptic, to say the least, it gives a general idea of what the program is doing and, in particular, details the arriving and departing packets and detected errors, if present.
-
Sometimes the ntpd. behavior may seem to violate the Principle of Least Astonishment, but there are good reasons for this. See the Network Time Protocol (NTP) daemon page for revealing insights. See this page and its dependencies for additional configuration and control options. The Notes on Configuring NTP and Setting up a NTP Subnet page contains an extended discussion of these options.

Performance

Really good. With the VP/UT+, the generated PPS pulse is referenced to UTC(GPS) with better than 50 nsec (1 sigma) accuracy. The limiting factor will be the timebase of the computer and the precision with which you can timestamp the rising flank of the PPS signal. Using FreeBSD, a FPGA based Timecounter/PPS interface, and an ovenized quartz oscillator, that performance has been reproduced.
