在CentOS 5和6 Linux中使用iptables --如何防止以root、apache或任何人的身份运行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中:
-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,得到了错误:
# 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.

尝试使用数字UID而不是名称。例如:
-A OUTPUT -m owner --uid-owner 400 -j DROP而不是
-A OUTPUT -m owner --uid-owner apache -j DROP您可以通过键入
