There are sockets in a system.
Sometimes a firewall can pass packets due to its malfunction or not

If there are no extra sockets it is much much better for security.

I ilked Chrony and will use it instead of NTPd on 3 of 5 interfaces of the
server.
One thing that stopped me from using Chrony on a real server is lack of
multiple bindings.
