Fedora18通过firewall-cmd命令修改防火墙ssh访问

使用root用户

查看所有的zone信息
# firewall-cmd --list-all-zones

查看默认zone是哪一个
# firewall-cmd --get-default-zone

临时修改接口p3p1所属的zone为internal,这是runtime修改,重启不保存
# firewall-cmd --zone=internal --change-zone=p3p1

如果需要重启保存接口的修改
则修改接口对应的配置文件/etc/sysconfig/network-scripts/ifcfg-p3p1
在配置文件中增加或修改一行ZONE=internal

从public zone中移除服务,重启后保存
临时修改则去掉--permanent选项
# firewall-cmd --permanent --zone=public --remove-service=ssh


这样便无法从接口p3p2上通过ssh访问了
但是可以从内网接口p3p1上通过ssh访问


再次查看所有的zone信息
# firewall-cmd --list-all-zones
