Symptoms

When NTP is configured on Gaia OS machine, machine responds to queries from hosts (in case it allows connections on NTP port - UDP port 123).

Example:

[Expert@HostName]# ntpq
ntpq> peers
     remote           refid      st t when poll reach   delay   offset  jitter 
============================================================================== 
 172.16.30.109        .INIT.     16 u    -  512    0    0.000    0.000   0.000 
 192.168.70.183       .INIT.     16 u    -  512    0    0.000    0.000   0.000

Cause

Enabling use of an NTP server in the Gaia configuration automatically starts the NTP daemon.
The daemon acts as a client and server by design.
