Hi, just a quick note to whoever is maintaining this page: http://wiki.centos.org/HowTos/Network/SecuringSSH The procedure is missing the firewall-cmd calls necessary in EL7: firewall-cmd --add-port 2345/tcp firewall-cmd --add-port 2345/tcp --permanent Also, it may be worth mentioning that semanage is in the policycoreutils-python package, which isn’t installed by default in all stock configurations.
