Two pfSense boxes and NTP



  • Trying to make pfSense-nano to get time from pfSense-1.2.3
    On client I see
    21 May 09:58:09 ntpdate[46964]: no server suitable for synchronization found
    21 May 09:58:14 ntpdate[46967]: no server suitable for synchronization found

    On the server I see
    09:59:04.710161 IP 192.168.81.251.123 > 192.168.81.252.123: NTPv4, Client, length 48

    Can somebody explain why it is not working?
    Thanks.

  • Have you started the NTP server on pfSense?

    Have you searched the forum?  It's a known and much discussed issue that OpenNTPd takes some time (tens of minutes, maybe longer) to sync, unlike the ISC implementation.



  • Yes, I am sorry for posting. After an hour or so it is ok now.



  • No problem.  It wouldn't happen if pfSense used ISC's version ;)
