Firepass - 一种隧道技术工具，通过它可以避开防火墙的规则约束，将数据流封装在合法的HTTP POST请求中。任何基于TCP/UDP协议的子协议可以通过它来穿越HTTP代理服务器对HTTP协议的严格审查。到目前为止，客户端和服务器端仅用PERL语言编写。服务器端作为一个CGI脚本运行在WEB服务器上。Firepass的主要特点是用户可以在外网使用几种方法安装服务器端脚本。用户无需在外网计算机上帮定任何端口。当服务端脚本被置于企业WEB服务器上，客户端脚本从外部网络和它通信时，Firepass也可适用于反弹作业。-Firepass-a tunnel technology tools, it can be avoided through the firewall rules to the data flow Packaging legitimate HTTP POST request. Any TCP/UDP protocol for the agreement to cross through its HTTP proxy server to the HTTP protocol rigorous review. So far, the client and server side only PERL language. Server as a CGI script is running on Web servers. Firepass are the main characteristics of network users who can use several methods to install the server-side scripting. Net users who need computer help any port. When the service was placed in the script-enterprise Web server, the client script from the network and its external communications, Firepass also apply to rebound operations.

一个Linux下的五子棋对战游戏，可以给学习Linux下Socket编程的初学者参考。分为客户端和服务器端，客户端界面用QT开发，所以也可作为初学者学习QT的参考。-Under a Linux Gobang war games under Linux can learn Socket programming reference for beginners. Divided into client and server, the client interface developed by QT, so it can be used as a reference for beginners to learn QT.
