Then this paper concerns about the network packet intercepting technology of linux os and gives a thoroughly overview of network hacking methods and some application protocol criterion, including http, ftp, telnet, nntp, pop3, smtp etc. then the system design scheme of the transparent proxy has been discussed, this system can be divided to 4 modules below : establishment of transparent charnel, implement of proxy service, gui configuration and management application, accessory filter functions ( such as url filter, command filter and logger etc ). we explain key techniques in all 4 main parts of this system, define the interfaces of each module, what is more the main data structures and software implements codes are all illustrated
首先,論文陳述了防火
墻的相關技術基礎,分析了透明代理作為一種先進易用的防火
墻技術的原理,闡述了linux操作
系統網路數據包攔截技術和http 、 ftp 、 telnet 、 nntp 、 pop3 、 smtp等應用層協議的協議規范和具體的工作流程。接著敘述了本透明代理服務器的
系統總體設計方案,將
系統分為以下幾個部分:透明通道建立、代理服務實現、 gui配置管理程序以及過濾功能(如url過濾、命令過濾和日誌審計等) 。論文然後分別介紹各個關鍵部分的具體實現要點,解釋了相互間的介面關
系,列出了主要數據結構和實現流程。

As a whole the system may compart three modules : ndis drivers in the kernel mode, the dll program in the user mode and the user application program, adopting the share memory technology three modules realize the data share of the control canal rule, the encapsulation data and the network neiborhood name and so on, so we can easily finis1 " the packet authentication by the control canal rule, improve the filtering efficiency of the system. whereas the current of firewall technology, the system has wide utily value and business value. this software is based on windows 2000 operating system, the programming language is chosen as visual c + + 6. 0 and win2000 ddk
從總體上可以劃分為以下三個模塊:核心層的ndis網路驅動程序、應用層的動態鏈接庫程序以及用戶應用程序,這三個模塊之間通過內存共享技術完成對控管規則、封裝數據、網上鄰居名字列表等數據的讀寫操作,從而很方便的根據控管規則實現了對網路封包的認證操作,提高了
系統的過濾效率。鑒于目前防火
墻技術的發展趨勢,本
系統具有廣泛的實用價值和商業價值,因此具有一定的推廣前景。軟體的開發基於windows2000操作
