I have a CentOS 6.4 server, it does not have any iptable rules, it runs NTP daemon as service using the following configuration:

```
  driftfile /var/lib/ntp/drift

  server 0.pool.ntp.org
  server 1.pool.ntp.org
  server 2.pool.ntp.org
  server 3.pool.ntp.org

  restrict default ignore
  restrict 127.0.0.1

```

When I run `ntpq` to query peers, the following response is received:

```
ntpq> peers
localhost.localdomain: timed out, nothing received

```

`dig` shows that:

```
localhost.localdomain.  86400   IN  A   127.0.0.1

```

Why doesn't ntp query work?
