  • 1.  Question on NTP + NTS

     
    Posted 12-06-2022 23:48

    Hi.

     

    I am unable to sync with public NTP server time.cloudfare.com but not with NTS enabled.

     

    TIME SYNC SUCCEEDS WITHOUT NTS:

    system {

       ntp {

            server 162.159.200.123 ;

        }

     

     

    lab@vmx-1> show ntp associations

         remote           refid     auth st t when poll reach   delay   offset  jitter

    ==============================================================================

    time.cloudflare.com

                     10.29.8.4         -  3 u    1   64    1    6.534   -0.143   0.000

     

     

    TIME SYNC FAILS WITH NTS DUE TO AUTHENTICATION FAILURE

    system {

       ntp {

            server 162.159.200.123 nts remote-identity hostname time.cloudflare.com;

       }

     

    [edit]

    lab@vmx-1# run show ntp associations   

         remote           refid     auth st t when poll reach   delay   offset  jitter

    ==============================================================================

    time.cloudflare.com

                     .AUTH.          NTS 16 u    -  128    0    0.000   +0.000   0.000

     

     

    TIME SYNC FAILS WITH NTS AND LOCALY-GENERATED PKI CERTIFICATE (NOT SURE WHY I WOULD NEED THIS, BUT MENTIONED IN DOCUMENTATION)

    system {

       ntp {

            server 162.159.200.123 nts remote-identity hostname time.cloudflare.com;

            nts local-certificate testname;

        }

     

    [edit]

    lab@vmx-1# run show ntp associations

         remote           refid     auth st t when poll reach   delay   offset  jitter

    ==============================================================================

    time.cloudflare.com

                     .AUTH.          NTS 16 u    - 1024    0    0.000   +0.000   0.000

    We are seeing this issue too:

    > show version 
    Hostname: 105979_NTP-3
    Model: srx300
    Family: junos-es
    Junos: 24.4R1.9

    > show ntp associations no-resolve
         remote               refid           auth  st  t  when  poll reach  delay     offset   jitter rootdelay rootdisp
    =====================================================================================================================

    ...

     94.198.159.15          .AUTH.             NTS  16  u     -  1024    0    0.000    +0.000    0.008    0.000    0.000

    Does anyone using Junos NTP client with NTS found a solution for this ?
