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。 -
Transparent model realization built in ip rebuilding, one course of rebuild, check and forward of ip data gram base mac frame and under united structure, and the method to realize stream filter base tcp datagram assorting management and special protocol rebuilding, and tcp datagram rebuilding have nothing to do with application protocol completely transparent for application have some innovations
保留mac地址，同一數據結構下的ip報文重組、檢查、轉發過程一氣呵成，將透明模式融合在ip重建過程中實現；在對tcp報文採取分類處理的指導思想下，通過重建專用tcp來實現流過濾；這些均為本文創新之處。 -
Theoretical source of transparent model " s advantages is discussed, and then solutions of its key technology, last a programming realization - setting network card promsic to receive packets, keeping mac address, and checking packets base mac frame to realize transparent model in ip protocol rebuilding. the key technologies of firewall are packet filter and application proxy both of which can " t keep in step with network attack development
鑒於此，本文從透明模式防火墻的特徵和功能出發，探討了其本質、技術實現要點及可行性方案，給出有別于上述兩方案的實現：網卡置於混雜模式，保留mac地址， ip重組、檢查、轉發過程一氣呵成，將透明模式的實現融合在ip重建中，使得整個防火墻體系結構更加緊湊，提高了效率。 -
In summary, research and realization of transparent model and stream filter technology are done in this essay
方案的關鍵為專用tcp的構建，不同於通用操作系統中以rfc文檔為模板的標準tcp實現。 -
Transparent model and stream filter technology of firewall are discussed in this essay
