If you are using Fedora >= 18, the server is probably running firewalld
, which you can disable by running
systemctl stop firewalld.service
as root. You might also want to read man firewall-cmd
to find out more about adding firewall rules.
If you are running an older version of Fedora (or one that has been upgraded from an older version), the server is probably running iptables
, which you can turn of by running
systemctl stop iptables.service
(using systemctl
assumes you are running Fedora >= 15, with systemd
as init deamon).
