[ntp:questions] Orphan Mode Configuration

Here's a working orphan mode configuration using broadcast mode and
symmetric keys.

The minimal configuration files needed by all orphan mode participants:

# /etc/ntp.conf
driftfile /var/lib/ntp/ntp.drift
keys   /etc/ntp.keys
trustedkey 1
tos orphan 5
broadcastclient
broadcast <your_broadcast_address> key 1

# /etc/ntp.keys
1 M password

Notes:

1. The system that will be polling remote time servers (or a local
refclock) must be started with those time sources present in ntp.conf

2. This configuration does not include any access restrictions. Use it
at your own risk

3. The file paths are the ones used by my OS; yours may differ

4. You should use your own key id and password instead of the defaults
of "1" and "password"
