This tells ntpd to ignore _ALL_ NTP packets from _ALL_ sources,
including the servers that you configured below. Bad advice.

You _MUST_ explicitly allow your remote time servers when you use
"restrict default ignore". Please see below.

Before using any restrict lines please review
http://support.ntp.org/Support/AccessRestrictions and take the time to
work through the decision tree for chosing your default restriction.

This line ought to include 'kod' and 'limited'.

restrict 1 nopeer nomodify notrap

> server 2 iburst

restrict 2 nopeer nomodify notrap

> server 3 iburst

restrict 3 nopeer nomodify notrap

> server 4 iburst

restrict 4 nopeer nomodify notrap
