FWIW, I'm working on a fresh install at the moment....doing some
"experimenting".
Using firewalld, ports 53 (DNS) and 67 (bootp) are not open. Additionally, after install
of the bind and dhcp packages they remain not open.
It is only when specifically configured to be opened are they. Also, when configured by
the firewall-config GUI, udp/tcp is open for port 53 but only udp is open for 67.
Well, I have done nothing to cause this "recent" change.
By "recent" I mean within the last few (4-5) days.
So, something is doing this, but have no idea how to track it down.
When Linux is doing so many things behind the scenes (which is nothing new),
it does not help when things become visible and make one to think or say
things
about Linux that were, for quite some years, reserved for windows.
So, how do I track this down?
