The device +drivers may be different, the input/output system may be +idiosyncratic and the libraries may have different semantics. It is +not possible in a software distribution such as this one to support +every individual sysdtem with a common set of binaries, even with +the same system but different versions. Therefore, it is necessary +to configure each system individually for each system and version, +both at compile time and at run time. In almost all cases, these +procedures are completely automatic and all the newbie user need do +is type "make" and the autoconfigure system does the rest. There +are some exceptions, as noted below.</p> + +<p>Some programs included in this distribution use cryptographic +algorithms to verify server authenticity and credentials. As +required by the International Trade in Arms Regulations (ITAR), now +called the Defense Trade Regulations (DTR), certain cryptographic +products and media, including the Data Encryption Standard (DES), +cannot be exported without per-instance license. For this reason, +the DES encryption routine has been removed from the the current +version, even though it is used only to compute a message digest. +Current DTR regulations allow export of the the MD5 message digest +routine, which is in fact the preferred algorithm, and this is +included in the current version.</p> + +<p>The NTP authentication routines conform to the interface used by +RSA Laboratories in the <tt>rsaref20.zip</tt> package, which was +formerly downloadable from <tt>ftp.rsa.com</tt> or via the web at +<tt>www.rsa.com</tt>, but this may no longer be the case. Outside +the US and Canada, the functionally identical <tt>rsaeuro.zip</tt> +package is available from J.S.A. Kapp and other sources. The +recommended way to integrate the routines in either package with +the NTP build procedures is to uncompress and extract the <tt> +rsaref20</tt> files in a top level directory with that name. Then +install a link to that directory from <tt>rsaref2</tt> in the top +level directory of the distribution. Use <tt>rsaeuro1</tt> instead +for that distribution. These steps must be completed +before the configuration process described below.</p> + +<h4>Building and Installing under Unix</h4> + +Make sure that you have all necessary tools for building +executables. These tools include <tt>cc/gcc, make, awk, sed, tr, +sh, grep, egrep</tt> and a few others. Not all of these tools exist +in the standard distribution of modern Unix versions (compilers are +likely to be an add-on product - consider using the GNU tools and +<tt>gcc</tt> compiler in this case). For a successful build, all of +these tools should be accessible via the current path. + +<p>The first thing to do is uncompress the distribution and extract +the source tree. Use the <tt>./configure</tt> command to perform an +automatic configuration procedure. This command inspects the +hardware and software environment and tests for the presence of +system header files and the contents of these files to determine if +certain features are present. When one or more of these features +are present, the code is compiled to use them; if not, no special +code is compiled. However, even if the code is compiled to use +these features, the code does a special test at run time to see if +one or more are actually present and avoids using them if not +present. In such cases a warning message is sent to the system log, +but the daemon should still work properly.</p> + +<p>The default build normally includes the debugging code, which +can be useful in diagnosing problems found in initial test, and all +reference clock drivers known to work with each machine and +operating system. Unless memory space is at a premium, this is a +sensible strategy and saves lots of messy fiddling. If you need to +delete either the debugging code or one or more or all reference +clock drivers to save space, see the <a href="config.htm"> +Configuration Options</a> page.</p> + +<p>If your site supports multiple architectures and uses NFS to +share files, you can use a single source tree to compile +executables for all architectures. While running on a target +architecture machine and with the distribution base directory +active, create a subdirectory using a command like <tt>mkdir +A.`config.guess`</tt>, which will create an architecture-specific +directory with name peculiar to the architecture and operating +system. Then change to this directory and configure with the <tt> +../configure</tt> command. The remaining steps are the same whether +building in the base directory or in the subdirectory.</p> + +<h4>Compilation</h4> + +Peruse the operating-system-specific information for your +architecture under <a href="hints.htm">Hints and Kinks</a>. + +<p>Use the <tt>make</tt> command to compile all source modules, +construct the libraries and link the distribution. Expect few or no +warnings using <tt>cc</tt> and a moderate level of warnings using +<tt>gcc</tt>. Note: On some Unix platforms the use of <tt>gcc</tt> +can result in quite a few complaints about system header files and +type inconsistencies, especially about pointer variables. This is +usually the case when the system header files are not up to ANSI +standards or <tt>gcc</tt>-isms, when gcc is not installed properly, +or when operating system updates and patches are applied and gcc is +not reinstalled. While the autoconfigure process is quite thorough, +the Unix programming cultures of the various workstation makers +still remain idiosyncratic.</p> + +<h4>Installation</h4> + +As root, use the <tt>make install</tt> command to install the +binaries in the destination directory. You must of course have +write permission on the install in the destination directory. This +includes the following programs: + +<ul> +<li><a href="ntpd.htm"><tt>ntpd</tt> - Network Time Protocol (NTP) +daemon</a></li> + +<li><a href="ntpq.htm"><tt>ntpq</tt> - standard NTP query +program</a></li> + +<li><a href="ntpdc.htm"><tt>ntpdc</tt> - special NTP query +program</a></li> + +<li><a href="ntpdate.htm"><tt>ntpdate</tt> - set the date and time +via NTP</a></li> + +<li><a href="ntptrace.htm"><tt>ntptrace</tt> - trace a chain of NTP +servers back to the primary source</a></li> +</ul> + +<p>If the precision time kernel modifications are present, the +following program is installed:</p> + +<ul> +<li><a href="ntptime.htm"><tt>ntptime</tt> - read kernel time +variables</a></li> +</ul> + +<p>If the public key authentication functions are present, the +following program is installed:</p> + +<ul> +<li><a href="genkeys.htm"><tt>ntp-genkeys</tt> - generate public +and private keys</a></li> +</ul> + +<p>In some systems that include the capability to edit kernel +variables, the following program is installed:</p> + +<ul> +<li><a href="tickadj.htm"><tt>tickadj</tt> - set time-related +kernel variables</a></li> +</ul> + +<h4>Configuration</h4> + +<p>You are now ready to configure the daemon and start it. You will +need to create a NTP configuration file <tt>ntp.conf</tt> and +possibly a cryptographic key file <tt>ntp.keys</tt>. Newbies should +see the <a href="quick.htm">Quick Start</a> page for orientation. +Seasoned veterans can start with the <a href="ntpd.htm"><tt> +ntpd</tt> - Network Time Protocol (NTP) daemon</a> page and move on +to the specific configuration option pages from there. A tutorial +on NTP subnet design and configuration options is in the <a href= +"notes.htm">Notes on Configuring NTP and Setting up a NTP +Subnet</a> page.</p> + +<h4>If You Have Problems</h4> + +<p>If you have problems peculiar to the particular hardware and +software environment (e.g. operating system-specific issues), +browse the <a href="hints.htm">Hints and Kinks</a> page. For other +problems a tutorial on debugging technique is in the <a href= +"debug.htm">NTP Debugging Technique</a> page. As always, the first +line of general assistance is the <a href="http://www.ntp.org">NTP +web site www.ntp.org</a> 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. Bug reports of a specific +nature should be sent to <a href="mailto:bugs@mail.ntp.org"> +<bugs@mail.ntp.org></a>. Bug reports of a specific nature on +features implemented by the programmer corps mentioned in the <a +href="copyright.htm">Copyright</a> page should be sent directly to +the implementor listed in that page, with copy to +bugs@mail.ntp.org.</p> + +<p>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 <tt>config.guess</tt> in your bug report. It +will look something like:</p> + +<p><tt>pdp11-dec-fuzzos3.4</tt></p> + +<p>Additional <tt>make</tt> commands</p> + +<dl> +<dt><tt>make clean</tt></dt> + +<dd>Cleans out object files, programs and temporary files.</dd> + +<dt><tt>make distclean</tt></dt> + +<dd>Does the work of <tt>clean</tt>, but cleans out all directories +in preparation for a new distribution release.</dd> + +<dt><tt>make dist</tt></dt> + +<dd>Does the work of <tt>make distclean</tt>, but constructs +compressed tar files for distribution. You must have GNU automake +to perform this function.</dd> +</dl> + +<h4>Building and Installing under Windows NT</h4> + +See <tt><a href="hints/winnt.htm">hints/winnt.htm</a></tt> for +directions to compile the sources and install the executables. + +<hr> +<a href="index.htm"><img align="left" src="pic/home.gif" alt= +"gif"></a> + +<address><a href="mailto:mills@udel.edu">David L.
