208 Chapter 7

Conﬁguring NTP

This chapter contains information about how to conﬁgure and use

xntpd. xntpd is a daemon that maintains the local clock on an HP-UX

workstation in agreement with Internet-standard time servers. xntpd is

an implementation of the Network Time Protocol (NTP) version 3

standard, as deﬁned in RFC 1305.

This chapter includes the following sections:

• “Overview” on page 209

• “Conﬁguration” on page 214

• “Starting xntpd” on page 226

• “Stopping xntpd” on page 227

• “Querying xntpd” on page 228

• “Troubleshooting ntp” on page 230

You can use SAM to conﬁgure xntpd.

NOTE xntpd is an HP implementation of version 3.2 of a publicly-available

NTP daemon. HP provides support for the features documented in this

chapter and in the xnptd man page. Other features of the

publicly-available daemon may work; however, they are not supported by

HP.
