5194.0. "NTP and Spectracom NetClock" by CSC32::B_HODGKINS () Tue Feb 04 1997 10:58

    
    Checking to see if there is any know problems running NTP if the 
    Spectracom NetClock/2 reference clock. He is running ucx 3.3 eco7 
    at this time. Told him to upgrade to v4.1 but he does not want
    to upgrade the 1800 systems unless we can prove to him the problem
    is corrected in the new version.
    
    I finally wound up setting up our Spectracom NetClock/2 reference clock
    on a PC running Linux since I couldn't get either the VMS/UCX or the
    Digital Unix NTP daemons to work with the clock (see C970102-3712 and
    C970110-2773).  The NTP on the Linux kit seems to be working just fine;
    all the other system types (VMS-UCX, DU, Ultrix, and various PC SNTP
    clients) seem to be able to use directly as a server.  However, when I
    enabled the "broadcast server" mode on the Linux system, the VMS/UCX
    daemon ceased functioning.
    
    All the VMS/UCX immediatedly acquired the Linux server as a "peer", but
    never seemed to complete synchronizing with it.  In this log file
    segment, the broadcast server was turned on at 12:52, and this is all
    that was written until I killed the daemon at 15:15 to restart it:

     12:52:29.39    -0.074867 seconds, trip 0.2497, aperture 0.0749, hold 4
    
    The log file from the restart at ~15:16 isn't any better.  It never
    synchronizes with anything until 6:30 the next morning when I gave up
    and turned off the broadcast server mode:

    Is there any way to get the UCX NTPD to either synchronize properly
    with
    the NTP broadcast messages, or to even simply ignore them.  I need to
    be
    able to use the broadcast server mode to handle all the PC based
    clients, but can't afford to loose NTP on the VMS server at the same
    time.
    
    
    Thanks
