Step 4
Edit the ntp.conf file by changing multicastclient to server followed by the IP address of the target
NTP server:
# @(#)ntp.client 1.2 96/11/06 SMI
#
# /etc/inet/ntp.client
#
# An example file that could be copied over to /etc/inet/ntp.conf; it
# provides a configuration for a host that passively waits for a server
# to provide NTP packets on the ntp multicast net.
#
server 172.22.255.1
Step 5
Go to the directory /usr/lib/inet/ and start the NTP daemon by entering the xntpd command.
The daemon sets and maintains the time-of-day of the operating system in agreement with the master
time server.
onionring:/etc/inet$ cd /usr/lib/inet/
onionring:/usr/lib/inet$ ls
in.dhcpd xntpd
onionring:/usr/lib/inet$ xntpd
onionring:/usr/lib/inet$
Step 6
Verify that the NTP daemon is running by entering the ntpq -p command:
onionring:/usr/lib/inet$ ntpq -p

The following information appears:
•
The remote NTP server to which the workstation is connected.
•
The reference ID.
•
The stratum level of the server.
•
The type of NTP packet that was received by the client (local, unicast, multicast, or broadcast).
•
The polling interval in seconds.
•
The reachability register in octal.
•
The current delay of the server in seconds.
•
The current offset of the server in seconds and the dispersion of the server in seconds.
•
The delay, offset, and displacement between the client and the server in seconds.
When the daemon starts, most of the time values will be zeros until there is a sufficient number of
queries taken by the daemon to determine the correct offset.
