Issue/Introduction



Symptoms
You notice that the time of the SSIM appliance is drifting more than a few minutes from the NTP controlled times on the network

 

Cause

There are some restrictions in the ntp.conf file that is created when you setup the NTP configuration in the SSIM Web Configuration page. You will need to remove these restrictions.

Resolution

Note:  This is only for Security Information Manager v4.5 or Security Information Manager v4.6

Original ntp.conf file:


    restrict default ignore
    server 10.216.221.103
    restrict 10.216.221.103 nomodify nopeer noquery notrap
    server 127.127.1.0 # local clock
    fudge 127.127.1.0 stratum 10
    restrict 127.0.0.1
    driftfile /var/lib/ntp/drift



Modify the ntp.conf file and remove these restrictions: nomodify nopeer noquery notrap.

Sample edited ntp.conf file:

    restrict default ignore
    server 10.21.221.103
    server 10.21.221.103
    restrict 10.21.221.103
    server 127.127.1.0 # local clock
    fudge 127.127.1.0 stratum 10
    restrict 127.0.0.1
    driftfile /var/lib/ntp/drift
