I am trying to setup my Debian 6 (Squeeze) VM to act as a local time server for my network. I have it set to sync with `tock.usno.navy.mil` which is a stratum 1 server.

I am having some problems finding any information on how to setup the ntp daemon to serve the time to clients requesting the time. I have looked through the ntpd man page and that was probably the best doc I found. [support.ntp.org](http://support.ntp.org/bin/view/Main/WebHome) was pretty much useless to me, the documentation I found was talking more about how NTP works not how to configure a server.

I also noticed I am not getting anything in my logs about being synced with the server that I am listed.

Any help anyone can offer would be great, I am not sure what is wrong. I am sure it is something I am doing. I had a previous time server running but my SAN blew up and I was not making backups since it was for testing. So I have no old config to look at.

Here is a copy of `ntp.conf` since there is nothing in here that has a any personal information I thought posting might help.

```
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /var/lib/ntp/ntp.drift

# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable

# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example

# pool.ntp.org maps to about 1000 low-stratum NTP servers.  Your server will
# pick a different set every time it starts up.  Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
server tock.usno.navy.mil iburst

# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details.  The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery
restrict 10.0.0.0 mask 255.255.255.0 notrap nomodify

# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1

# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust

# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
#broadcast 192.168.123.255

# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines.  Please do this only if you trust everybody on the network!
#disable auth
#broadcastclient

```

Here the output from `ntpq -p`

**Update**

When I remove the line `restrict 10.0.0.0 mask 255.255.255.0 notrap nomodify` from my config ntp seems to spring to life. This is what I see now when I look at `ntpq -p`
