I am trying to get NTPd working on my RedHat 9.0 system. I system is having problems keeping the correct time. I edited my ntp.conf file and started ntpd. But everytime I run ntpq - p all my values come back as 0 (jitters of 4000 as well) from what I have read, this means that NTP is not working.

my ntp.conf file is as follows:

# Prohibit general access to this service.
restrict default ignore

# Permit all access over the loopback interface. This could
# be tightened as well, but to do so would effect some of
# the administrative functions.

# -- CLIENT NETWORK -------
# Permit systems on this network to synchronize with this
# time service. Do not permit those systems to modify the
# configuration of this service. Also, do not use those
# systems as peers for synchronization.
# restrict mask notrust nomodify notrap

# or remove the default restrict line
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.

restrict mask nomodify notrap noquery
restrict mask nomodify notrap noquery

#multicastclient # listen on default
# restrict mask notrust nomodify notrap
# restrict mask notrust nomodify notrap

# 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.
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 /etc/ntp/drift
broadcastdelay 0.008

# Authentication delay. If you use, or plan to use someday, the
# authentication facility you should make the programs in the auth_stuff
# directory and figure out what this number should be on your machine.
authenticate yes

# Keys file. If you want to diddle your server at run time, make a
# keys file (mode 600 for sure) and define the key number to be
# used for making requests.
# systems might be able to reset your clock at will. Note also that
# ntpd is started with a -A flag, disabling authentication, that
# will have to be removed as well.
keys /etc/ntp/keys


What am I doing wrong? is there anyone out there that has ntp working on redhat that could post there ntp.conf file?

Thanks for the help


also, running ntpdate works fine, but i dont want to have to run this every day. NTPD seems like a better fix.
