    Hi!

    I have a problem to configure properly a ntpd server for local network. I
    followed a handbook example, but maybe I didn't understand something well. My
    aim is to configure a ntpd server, allow to synchronize computers from local
    network according to this server and hide mentioned ntpd server for all
    computers out of local network.

    My ntp server is:

    >uname -a
    FreeBSD hilbert.chtf.stuba.sk 4.9-STABLE FreeBSD 4.9-STABLE #0: Wed Feb 11
    18:23:18 CET 2004 root@hilbert.chtf.stuba.sk:/usr/obj/usr/src/sys/HILBERT
    i386
    >

    ntpd server is allowed in rc.conf with no additional flags:

    xntpd_enable="YES"

    Its IP is 147.175.67.128, network is class B: 147.175.0.0 with netmask
    255.255.0.0. My ntp.conf:

    server public.stratum2.server1
    server public.stratum2.server2
    server public.stratum2.server3
    driftfile /var/db/ntp.drift
    # default to ignore
    restrict default ignore
    # allow my net to configure, byt not act my setting (according to handbook):
    restrict 147.175.0.0 mask 255.255.0.0 notrust nomodify notrap

    Server synchronize itself well, but when I try query from 147.175.64.41, i
    obtain:

    > ntpdate -vq 147.175.67.128
    23 Feb 07:54:52 ntpdate[6145]: ntpdate 4.1.0-a Fri Feb 6 09:54:31 CET 2004 (1)
    server 147.175.67.128, stratum 16, offset 0.301619, delay 0.02689
    23 Feb 07:54:52 ntpdate[6145]: no server suitable for synchronization found
    >

    ntpd is already running for several days, so it si synchronized and -- i think
    -- ready to serve.

    Can you help me with appropriate 'restrict' rule sets? No firewall is running
    here.

    Thanks, Jozef.
