Changing NTP Server On RSA Appliances

In order to change the NTP server, we will have to carry out the following steps via Putty (An open source telnet and SSH Client for the Windows and Unix platforms):

1. Login using the account emcsrv and key in the password when prompted.

2. Change to root and key in the password when prompted:

    bash-3.00$ sudo su

3. Navigate to the directory where the NTP configuration file resides:

    bash-3.00$ cd /etc

4. Edit the file NTP.CONF and locate the “server” line. Specify the NTP server to be added and save the file:

    bash-3.00$ vi ntp.conf

    For example:
    # server mytrustedtimeserverip
    server 192.168.7.22

5. Enter the below command to enable the NTPD service to start when the appliance is rebooted:

    [root@Primary/ ]# /sbin/chkconfig –levels 2345 ntpd on

6. Restart the NTPD service for the change to take effect:

    [root@Primary/ ]# /sbin/service ntpd restart

7. The appliance immediately synchronizes its time with the NTP server and sets the hardware clock automatically.  You can verify that the NTPD service is running using the below command:

    [root@Primary/ ]# ntpq –p

Repeat the above steps at the Replica.
