NTP synchronization frequency

Hi all, how can I determine how often my UTM Sophos synchronizes time with the public NTP servers listed in the Management, System Settings, Time and Date, Synchronize Time with Internet Server tab?


Thanks 1000 in advance.

  • ntpdc can provide statistics. I'm pretty sure sophos didn't change the adaptive scheme used in vanilla ntpd.

  • Hi  , the commands I launch from ntpdc go into time-out

    <M> sophosutm:/var/mdw/scripts # ntpdc
    ntpdc> host 127.0.0.1
    current host set to 127.0.0.1
    ntpdc> peers
    127.0.0.1: timed out, nothing received
    ***Request timed out
    ntpdc> sysinfo
    127.0.0.1: timed out, nothing received
    ***Request timed out
    ntpdc> exit

    Instead I found ntpq..

    <M> sophosutm:/var/mdw/scripts # ntpq
    ntpq> host 127.0.0.1
    current host set to 127.0.0.1
    ntpq> sysinfo

    Then, the poll column is the one that indicates the polling intreval? Then the utm synchronizes every 16 seconds?
