So yeah, configuring Fedora 20's firewall-cmd. Tried to limit inbound traffic to only http, https, and ssh. However, the machine still responds to pings, and the --get-service command shows a laundry list of things I do not use.
Why the disconnect?
Is the --get-service command accurate, or is the --list-services command accurate?
If the latter, why does ping get through?

Additionally, excerpts from iptables -L -n.
