NTP Configuration- AIX Client and Server

AIX Server Configuration:

NTP : Network Time Protocol. Used for time synchronization to perform and support real-time applications.

1) vi /etc/ntp/.conf
# comment the Broadcast line

2) Include the entry,

server 127.127.X.Y, where Y refers to the statum value for the purpose of synchronization. Statum value should be 0 to 3. Save the file.

3) # startsrc -s xntpd

4) # lssrc -ls xntpd

AIX Client Configuration:

1) Ensure there is a proper communication between the client and server.

2) Edit the configuration file for NTP.

# vi /etc/ntp.conf

3) Include the line

server <IP Address of the NTP Server or Name of the NTP Server>

4) Save the file.

5) # startsrc -s xntpd

NTP Syncronization process will take ~10 mins.

6) # lssrc -ls xntpd, if the statum value is "16". It shows no syncronization between the NTP Client and Server.

7) In that case manually configure the NTP,

# ntpdate <IP Address of the NTP Server or Name of the NTP Server>

8) Verify the same.

# ntpq -a or ntpq -peers
