Configuring NTP in PowerVM VIOS

1. Login to the VIOS as padmin user.
2. To configure VIOS as NTP client, edit /home/padmin/config/ntp.conf with vi (there is no nano) and add your NTP server to the NTP configuration file.
   
   $ vi config/ntp.conf Add the line: server <your_NTP_Server_FQDN>
   
   For example, if your NTP Server is ntpserver.austin.ibm.com, your file should look something like this:
   

   ...
   # IBM_PROLOG_END_TAG
   # server time3-1b.austin.ibm.com
   # server time3-2c.austin.ibm.com prefer
   server time.nrc.ca prefer
   driftfile /home/padmin/config/ntp.drift
   tracefile /home/padmin/config/ntp.trace
   logfile /home/padmin/config/ntp.log

3. Once NTP is configured, start the xntpd service: $ startnetsvc xntpd
4. To stop the daemon, run: $ stopnetsvc xntpd
5. To check status of xntpd daemon, run: $ lsnetsvc xntpd
