【正文】 技術(shù)中, 監(jiān)測 過濾技術(shù)是一個(gè)廣泛使用的技術(shù)。從小型公司員工上網(wǎng)浪費(fèi)工作時(shí)間和公司資源,到商業(yè)間諜通過一封郵件將公司機(jī)密泄露,無不體現(xiàn)著網(wǎng)絡(luò) 監(jiān)測 的必要性。 2 網(wǎng)絡(luò) 監(jiān)測 和過濾技術(shù) 伴隨著互聯(lián)網(wǎng)的迅速普及,良莠不齊的網(wǎng)絡(luò)發(fā)布內(nèi)容日漸泛濫。 綜合運(yùn)用以前所學(xué)的專業(yè)知識,設(shè)計(jì)開發(fā)一個(gè)互聯(lián)網(wǎng) 監(jiān)測 軟件,本設(shè)計(jì)要求實(shí)現(xiàn)能夠自動獲取目標(biāo)論壇的發(fā)布內(nèi)容,系統(tǒng)針對發(fā)帖作者、發(fā)帖時(shí)間、帖子URL、帖子標(biāo)題和帖子正文等關(guān)鍵字段開放基于單個(gè)字段或是組合選項(xiàng)的熱點(diǎn)查詢等這些功能,具體包括以下內(nèi)容: 1. 在設(shè)計(jì)與開發(fā)中,重點(diǎn)如何解決客 戶發(fā)的信息能夠捕獲到的問題; 2. 在設(shè)計(jì)與開發(fā)中, 難點(diǎn) 是對捕獲的信息過濾的問題 。 同時(shí)企業(yè)如何能夠從海量的數(shù)據(jù)信息中獲取民眾焦點(diǎn)和 社會輿論動向已經(jīng)成為 管理部門日常工作的重中之重。 聲 明 ................................................... 錯誤 !未定義書簽。 參考文獻(xiàn) ................................................... 錯誤 !未定義書簽。 filter。 “資源共享,信息互通” 需要更多相關(guān)設(shè)計(jì)資料和源代碼加 :493703123 Design and Implementation of the Inter Forum Detective System Abstract As the inter has been developing rapidly, the inter forum has brought many convenient to the people. But at the same time, it also has been having a series of questions, such as spreads the pornography, declares the reactionary opinion, divulges the secret of technology, etc. Therefore the requirement of the Inter forum detective system has been stared in the face, and thorough analysis for the system has the extremely vital significance. The thesis introduces the base knowledge of work, the principle of the work detecting and filter. Pointed out a method of how the data transport from the customer to the server. The thesis has analyzed the goal of inter forum detective system, the principle of system position and the function module. The important module includes the module of capture package, module of decode, module of matching. The system proposes the broadcast characteristic of Ether, using the BPF technology to gain the work information in the mon work environment. The system has base on Linux operation system, transferring a libpcap storeroom function to grasp the package, analyzing the content of the package and finding the bad message in order to realize the function of filter. The thesis uses the method which was referred just now to construct the system detective, and it realizes some of its functions. Key words: The forum detecting。利用文中介紹的方法來構(gòu)建 監(jiān)測 系統(tǒng),能起 到一定的 監(jiān)測 作用。它還提出了利用以太網(wǎng)的廣播特性,在共享 式網(wǎng)絡(luò)環(huán)境下使用 BPF 技術(shù)來獲取傳輸中的信息。分析了互聯(lián)網(wǎng)論壇監(jiān)測 系統(tǒng)的目的、系統(tǒng)的組成原理和系統(tǒng)的功能模塊。因此人們對網(wǎng)絡(luò)論壇內(nèi)容監(jiān)測 的需求已經(jīng)迫在眉睫,而對它的深入分析和研究就更具有極為重要的意義。 互聯(lián)網(wǎng)論壇監(jiān)測系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn) 摘 要 互聯(lián)網(wǎng) 發(fā)展迅速, 網(wǎng)絡(luò)論壇也隨之發(fā)展起來。它在給人們帶來了諸多方便的同時(shí)也產(chǎn)生了諸如傳播色情暴力、發(fā)表反動 言論和泄漏技術(shù)機(jī)密等一系列嚴(yán)重的問題。 本文介紹了網(wǎng)絡(luò)基礎(chǔ)知識、網(wǎng)絡(luò)監(jiān)測 和過 濾的原理以及數(shù)據(jù)從客戶端傳到服務(wù)器端的方式。其主要模塊包括包捕獲模塊、解碼模塊、模式匹配模塊。系統(tǒng)在 Linux 操作系統(tǒng)下,調(diào)用 Libpcap 庫函數(shù)來實(shí)現(xiàn)抓包,對包中的內(nèi)容進(jìn)行分析, 找出有害的信息 ,從而實(shí)現(xiàn)過濾功能。 關(guān)鍵詞 :論壇 監(jiān)測 ; 抓包;過濾; 伯克利數(shù)據(jù)包過濾器 “ IT 開拓者 3 網(wǎng)絡(luò)工作室”成立于 2021 年,是一個(gè)專業(yè)的計(jì)算機(jī)軟件開發(fā)團(tuán)隊(duì)。 Libpcap。 BPF 目 錄 論文總頁數(shù): 25 頁 1引 言 ..................................................................... 1 ................................................................ 1 ...................................................... 1 ...................................................... 1 2網(wǎng)絡(luò)監(jiān)測和過濾技術(shù) ........................................................ 1 ...................................................... 1 ................................................................ 2 ..................................... 3 ................................................................ 3 3系統(tǒng)需求分析 .............................................................. 4 .................................................. 4 ............................................ 4 ................................................ 5 ...................................................... 6 .......................................................... 6 4論壇監(jiān)測軟件設(shè)計(jì)的總體方案 ................................................ 8 .................................................. 9 ........................................... 10 5論壇監(jiān)測軟件的實(shí)現(xiàn) ....................................................... 11 ............................................... 11 ............................................... 12 ............................................................. 12 ....................................................... 12 ............................................. 15 ................................................... 16 6結(jié)果測試,性能分析 ....................................................... 20 : ........................................................... 20 ............................................................. 20 ............................................. 20 ............................................. 21 網(wǎng)關(guān)的配置 ....................................................... 21 測試方法與結(jié)果 ................................................... 21 ............................................... 21 ............................................. 22 ....................................................... 22 ................................................... 22 結(jié) 論 ................................................... 錯誤 !未定義書簽。 致 謝 ................................................... 錯誤 !未定義書簽。
