    NPT Server - NTP Client no sync

    hi guys

    since I got a secure area my linux servers don't not have internet connection at all...

    so I've configured an NTP Linux server with this configuration but my NTP Linux Client are not sync the time with the NTP Server


    1. I sync my NTP server to itselft
    # ntpdate -du ntpserver
    #service ntpd start
    2. I syn my linux clients
    # ntpdate -du ntpserver
    ntp service for clients is stop

    now my NTP server configuration

    # Permit time synchronization with our time source, but do not
    # permit the source to query or modify the service on this system.
    restrict default kod nomodify notrap nopeer noquery
    restrict -6 default kod nomodify notrap nopeer noquery
    # Permit all access over the loopback interface.  This could
    # be tightened as well, but to do so would effect some of
    # the administrative functions.
    restrict -6 ::1
    # Hosts on local network are less restricted.
    restrict mask nomodify notrap
    # Use public servers from the project.
    # Please consider joining the pool (
    #broadcast key 42         # broadcast server
    broadcastclient                 # broadcast client
    #broadcast key 42             # multicast server
    #multicastclient              # multicast client
    #manycastserver         # manycast server
    #manycastclient key 42  # manycast client
    # Undisciplined Local Clock. This is a fake driver intended for backup
    # and when no outside source of synchronized time is available.
    server     # local clock
    fudge stratum 10
    # Drift file.  Put this in a directory which the daemon can write to.
    # No symbolic links allowed, either, since the daemon updates the file
    # by creating a temporary in the same directory and then rename()'ing
    # it to the file.
    driftfile /var/lib/ntp/drift
    # Key file containing the keys and key identifiers used when operating
    # with symmetric key cryptography.
    keys /etc/ntp/keys

    when I run to sync my clients
    #ntpdate -du ntpserver
    results see the last line it says client is not sync by 87 what I have to do? which command so the time in my NTP client is the same as my NTP server?
