Here's a working orphan mode configuration using unicast mode for three
nodes:

The minimal configuration files needed for both systems:

# /etc/ntp.conf - System A (192.168.0.1)
driftfile /var/lib/ntp/ntp.drift
tos orphan 5
server 192.168.0.2 iburst
server 192.168.0.3 iburst
server pool.ntp.org iburst
server pool.ntp.org iburst
server pool.ntp.org iburst
server pool.ntp.org iburst

# /etc/ntp.conf - System B (192.168.0.2)
driftfile /var/lib/ntp/ntp.drift
tos orphan 5
server 192.168.0.1 iburst
server 192.168.0.3 iburst

# /etc/ntp.conf - System C (192.168.0.3)
driftfile /var/lib/ntp/ntp.drift
tos orphan 5
server 192.168.0.1 iburst
server 192.168.0.2 iburst

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. 'peer' associations may be used instead of 'server' associations
