NTP Setup AIX Client Side

NTP Setup AIX Client Side

Within any production environment it is advisable to implement an ntp server to
synchronize the date and time of all you server to one central clock. To configure
this on and AIX ( Client Side) , perform the following:

The client configuration for ntp is defined in the configuration file /etc/ntp.conf
and should resemble the following , where server point to the ip address of the ntp
server

root#> more xntp.conf

server 10.101.50.6
driftfile /etc/ntp.drift
tracefile /etc/ntp.trace


# To start the xntpd daemon, enter:

startsrc -s xntpd

# To stop the xntpd daemon, enter:

stopsrc -s xntpd

to configure xntpd to start up at boot time

Edit the /etc/rc.tcpip file, and near the bottom uncomment the
'start xntpd' line. This will ensure ntp client restart on reboot.


e.g.

root#> stopsrc -s xntpd
0513-044 The /usr/sbin/xntpd Subsystem was requested to stop.
root#> ps -ef | grep xntpd
root 499964 581830 0 12:33:58 pts/1 0:00 grep xntpd
root#> startsrc -s xntpd
0513-059 The xntpd Subsystem has been started. Subsystem PID is 499966.
root#> ps -ef | grep xntpd
root 499966 209062 0 12:34:10 - 0:00 /usr/sbin/xntpd
root 532568 581830 0 12:34:13 pts/1 0:00 grep xntpd
root#> date
Sun May 4 12:34:16 BST 200



Note : The /etc/rc.tcpip startup script which defines the TCP/IP daemons is called at boot time by
/etc/inittab

i.e.

root#> grep tcpip inittab

rcptcpip:23456789:wait:/etc/rc.tcpip > /dev/console 2>&1 # Start TCP/IP daemons
