Checking my one Fedora 21 host, sshd is enabled and started, right?

$ systemctl status sshd
â sshd.service - OpenSSH server daemon
    Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled)
    Active: active (running) since Fri 2015-09-18 07:53:47 PDT; 1 months

      Docs: man:sshd(8)
            man:sshd_config(5)
  Main PID: 704 (sshd)
    CGroup: /system.slice/sshd.service
            ââ704 /usr/sbin/sshd -D

I don't have apache installed since this one is frontend only. I 
disabled firewalld too since this is sitting on my LAN:

$ systemctl status firewalld
â firewalld.service - firewalld - dynamic firewall daemon
    Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
    Active: inactive (dead)

I leave selinux enabled as a matter of policy (get it?) on all my 
systems. I refuse to give in to the fools who say "oh just disable selinux!"
