使用CentOS 5和6
Linux中的iptables – 如何防止以root用户,apache或无人启动的进程启动传出连接？
在CentOS 5 Linux上,我尝试将这些行放入/ etc / sysconfig / iptables：
-A OUTPUT -m owner --uid-owner root -j DROP -A OUTPUT -m owner --uid-owner apache -j DROP -A OUTPUT -m owner --uid-owner nobody -j DROP
但不幸的是得到错误：
# sudo service iptables restart
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: iptables-restore v1.4.7: owner: Bad value for "--uid-owner" option: "apache"
Error occurred at line: 27
Try `iptables-restore -h' or 'iptables-restore --help' for more information.
[Failed]
尝试使用数字UID而不是名称.例如：

代替
-A OUTPUT -m owner --uid-owner apache -j DROP
您可以通过键入找到UID
id user
