system-config-firewall, replacement?

[hoinongdan]

I installed the firewall-config (yum install firewall-config) complete but typing firewall-config don't show window that give notice
** (firewall-config:3544): WARNING **: Could not open X display
** (firewall-config:3544): Gtk-WARNING **: cannot open display.
I would like to ask is I also install the package then?

It is an X program. Run it from an X term.
Otherwise use the command line program firewall-cmd.
man firewall-cnd
