[lug] NTP Configuration

Attached are the configurations I placed in the server's /etc/ntp.conf
file.  I have reject on my ppp0 device for the ntp port (both tcp and
udp).  (Note: Even without the ipchains reject rule . . . it doesn't
work.)  I executed ntpdate and I get the following:

13 Sep 14:01:28 ntpdate[598]: no servers can be used, exiting


Where did I go wrong?

Are there better peers to use for ntp in Colorado?

# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available. The
# default stratum is usually 3, but in this case we elect to use stratum
# 0. Since the server line does not have the prefer keyword, this driver
# is never used for synchronization, unless no other other
# synchronization source is available. In case the local host is
# controlled by some external source, such as an external oscillator or
# another protocol, the prefer keyword would cause the local host to
# disregard all other synchronization sources, unless the kernel
# modifications are in use and declare an unsynchronized condition.
