However, it doesn't take much to -fly the <tt>ntpd</tt> 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 <a href="build.htm">Building and Installing the -Distribution</a> page describes how to do this.</p> - -<p>While it is possible that certain configurations do not need a -configuration file, most do require one. Strictly speaking, the -file need only contain one line specifying a remote server, for -instance</p> - -<p><tt>server foo.bar.com</tt></p> - -<p>Choosing an appropriate remote server is somewhat of a black -art, but a suboptimal choice is seldom a problem. Links to public -time servers operated by National Institutes of Science and -Technology (NIST), US Naval Observatory (USNO), Canadian Metrology -Centre (CMC) and many others are given in the home page of this -document collection. The lists are sorted by country and, in the -case of the US, by state.

If the <tt>ntpd</tt> 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. Thus, for most applications an additional line should be -added to the file of the form</p> - -<p><tt>driftfile /etc/ntp.drift</tt></p> - -<p>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 <tt>ntpd</tt> fails to come up at all.</p> - -<p>The best way to confirm NTP is working is using the <a href= -"ntpq.htm"><tt>ntpq</tt></a> utility, although the <a href= -"ntpdc.htm"><tt>ntpdc</tt></a> utility may be useful in extreme -cases.
