filter command 中文意思是什麼
filter command
解釋
過濾命令-
In designing analogic circuit, we adopt programmable filter max262 to meet the system ' s command. after the step, we can make the signal ' s frequency width is wider and noise level is lower. to make the signal ' s amplitude to meet the analogic to digital device ' s command, we adopt the max551 to finish the gain control
在模擬電路部分，採用可編程濾波器max262 ，這樣就滿足了該數據採集裝置所採集的信號的頻率范圍較寬以及具有較低的噪聲水平的要求，為了使采樣到的信號的幅度滿足後面a d轉換器的要求，採用max551對采樣到的信號進行調理（增益控制） 。 -
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。 -
