Linux环境下自带了防火墙软件———ipchains,它以命令行的规则配置方式提供了齐全的数据包过滤功能。但ipchains的命令行方式,对用户来说使用非常不便,同时使得过滤规则的扩充和修改也极为繁琐。为了更为有效地配置防火墙的配置规则,本文针对ipchains设计了一个用过滤规则配置的图形界面,从而可以方便快捷地应用功能强大的ipchains。 Linux environment comes with a firewall software --- ipchains, which provides a full range of packet filtering features to the command line rule configuration. However, ipchains command line mode, the user is very inconvenient to use, while making the expansion and modification of the filter rules is extremely tedious. In order to configure the firewall configuration rules more effectively, this article designed a graphical interface for ipchains that uses a filtering rule to quickly and easily apply powerful ipchains.
