UTILITIES & FEATURES

 

 

Revised: 6 Sep 11 

4-8 

EST P/N AA107A 

 

 

3.  The  NTP  daemon  is  enabled  by  selecting  YES  for 

NTP  ENABLE

  (Figure  12).    When  enabled,  the  NTP 

daemon will use time services from upstream services to keep the time on this system accurate. 

 

4.  Next, the 

NTP SERVICE ENABLE

 should be configured to “YES,” if you want to allow the system to provide 

NTP service for clients wishing time synchronization (Figure 12). 

 

5.  The final step in configuring NTP services is to enter the IP address or the host name of the upstream NTP 

server.
