    Range of ports open on F30

    Hi,
    i was wondering if fedora 30 had any open ports by default.
    When i checked the ports with
    Code:
    firewall-cmd --list-ports
    i was very surprised what it told me.
    The output was
    Code:
    1025-65535/udp 1025-65535/tcp
    .
    Is this normal on a new fedora installation or should i worry?
    Wouldnt such a thing be a huge security issue?

    Thanks for answers

    They are known as high ports (1025 and higher). There is nothing listening on those ports by default and they are used for outgoing connections as well, otherwise your outgoing connections wouldn't work.

    I think the default is to allow ssh, dhcp6 and mdns (maybe I'm wrong, I can't remember exactly) and to block everything else.

    Check your /etc/firewalls/zones/ and see what your public.xml contains.
