Installation guide

/etc/rc.config file by using the /usr/sbin/rcmgr utility to
automatically start the NIS daemons when the system boots. On ULTRIX
systems, this is done by editing the /etc/rc.local file.
The DIGITAL UNIX system also has commands, such as ypcat, ypmatch,
and ypwhich, that allow you to get information from NIS. In addition, the
system has commands, such as yppasswd and yppush, that allow you to
maintain your NIS databases. These commands are the same on DIGITAL
UNIX systems as they are on ULTRIX systems.
Like an ULTRIX system, the DIGITAL UNIX system has a /etc/svc.conf
file that determines how your system uses NIS to find information. You can
use the svcsetup command to maintain the svc.conf file.
See the Network Administration manual for more information on NIS
configuration.
4.15.3 Time Services
The DIGITAL UNIX system includes the Network Time Protocol (NTP) and
Time Synchronization Protocol (TSP) for time synchronization.
NTP allows accurate, dependable, and synchronized time for hosts on both
wide area networks (WANs) (like the Internet) and local area networks
(LANs). In particular, NTP provides synchronization traceable to clocks of
high absolute accuracy, and avoids synchronization of clocks keeping
incorrect time.
The time daemon for the DIGITAL UNIX NTP is xntpd. This daemon is an
implementation of the NTP Version 2 standard as defined by the Internet
Request For Comment (RFC) 1119, omitting authentication. The daemon is
compatible with Version 1 servers, including the ntpd daemon available on
ULTRIX systems. For more information about the daemon, see xntpd
(8).
You normally use two commands to set and monitor time for the xntpd
daemon. The ntpdate command sets the locale date and time by polling
the NTP server you specify to determine the correct time. The ntpq
command monitors NTP servers that are running the xntpd daemon. For
more information about these commands, see ntpdate
(8) and ntpq(8).
The DIGITAL UNIX system has the ntpsetup command to help you
configure and run the xnptd daemon on a DIGITAL UNIX system. For
information about setting up NTP, see the Network Administration manual.
The DIGITAL UNIX system also includes the ntp and ntpdc commands to
allow you to monitor ULTRIX systems that run the ntpd daemon. For
more information, see ntp
(8) and ntpdc(8.)
