AIX as NTP Client

AIX as NTP Client
On machine that will be the client:
1. In file /etc/ntp.conf

Add:
server

prefer
driftfile /etc/ntp.drift
tracefile /etc/ntp.trace


2. Issue command:
ntpdate

NOTE:If it doesn't say "No server suitable for synchronization found" proceed
to next step.


3. Start using:
#smitty xntpd -> Start at both system restart and now
or
#startsrc -s xntpd

and uncomment the line in /etc/rc.tcpip
start /usr/sbin/xntpd -x "$src_running"


Let the daemon run for 6 miuntes before proceeding to the next step - or
may get stratum 16 error.


4.
#lssrc -ls xntpd
Stratum should show between 3-4, but longer is okay so long as not 16.

#ntpdate -d

(to sync server to client)
# ntpq -p

Start NTP Server and check /var/log/messages
# /etc/rc.d/init.d/ntpd start



You can use sysman to configure NTP client.

XNTP_SERV2="ntp_server2"
export XNTP_SERV2
XNTP_SERV3="ntp_server3"
export XNTP_SERV3
