【正文】 驗比較少，對于在編程上還存在著很大的不足之處，這也是 以后應(yīng)該予以重視 第 25 頁 共 27 頁 的地方， 理論 還需要 聯(lián)系了實際。 并且認(rèn)識 到實際當(dāng)中的設(shè)計和思想上與的課程設(shè)計是有很大的差別的。實際涉及到生產(chǎn)的設(shè)計是嚴(yán)謹(jǐn)?shù)?、科學(xué)的、有根據(jù)的、完整的。但我們所做 的課程設(shè)計是不完整的、不嚴(yán)謹(jǐn)?shù)?、是沒有考慮經(jīng)濟和使用價值為基礎(chǔ)的。而這一點恰恰是實際生活設(shè)計之中必須考慮的，也是很重要的。設(shè)計的目的就是經(jīng)濟又適用，達到實際生產(chǎn)的要求和目的，能更大更快的為使用廠家創(chuàng)造經(jīng)濟效益。 在設(shè)計中主要是完成了對于網(wǎng)卡信息的獲取還有對于網(wǎng)絡(luò)數(shù)據(jù)包捕獲功能的實現(xiàn)的函數(shù)，其中參考了一些網(wǎng)絡(luò)上的教程和書籍，通過閱讀和實踐來修改學(xué)習(xí)，最終通過掃描可用網(wǎng)絡(luò)接口并打開網(wǎng)卡接口來獲取到網(wǎng)卡的信息，然后再通過更改設(shè)置網(wǎng)卡的混雜模式后調(diào)用 Winpcap 中的函數(shù)來實現(xiàn)對于網(wǎng)絡(luò)數(shù)據(jù)包的捕獲并 且分析顯示出來。 從目前的完成情況來看這些功能已經(jīng)實現(xiàn)，不過還是感覺程序稍微顯得功能少了些。系統(tǒng)還存在一些不足之處，比如說，沒能實現(xiàn)對于數(shù)據(jù)包的阻塞拋棄這個功能感覺比較可惜還有就是保存下來的數(shù)據(jù)包用 UltraEdit 打開是亂碼這個問題暫時還沒有解決的頭緒。關(guān)于這個幾個問題還有再繼續(xù)豐富一些別的功能我會繼續(xù)下去直到最后，爭取做的更好更具有使用意義， 最后， 這是第一次單獨完成這么大代碼量的編程，由于 經(jīng)驗欠缺或者是其他方面的一些原因，這次的項目開發(fā)也存在一些不足，如 程序員邏輯比較混亂，一些簡單的問題要通過一堆無 用代碼才能實現(xiàn)，不能以簡潔有效的方式解決 ， 在以后的項目開發(fā)過程中會逐漸解決這些不足之處。 參考文獻 [1] 黃維通 .Visual C++面向?qū)ο笈c可視化程序設(shè)計 [M].北京：清華大學(xué)出版社 ,2021。 [2] ：協(xié)議 [M].北京：機械工業(yè)出版社 ,2021。 [3] 朱雁輝 .Windows防火墻與網(wǎng)絡(luò)封包截獲技術(shù) [M].北京：電子工業(yè)出版社 ,2021。 [4] 劉文濤 .網(wǎng)絡(luò)安全開發(fā) 包詳解 [M].北京：電子工業(yè)出版社 ,2021。 [5] 譚浩強 .C程序設(shè)計 [M].北京：清華大學(xué)出版社 ,1999。 [6] 張仕斌，譚三，易勇，蔣毅 .網(wǎng)絡(luò)安全技術(shù) [M].北京：清華大學(xué)出版社 ,2021。 [7] 閻慧，王偉，寧宇鵬 .防火墻原理及技術(shù) [M].北京：機械工業(yè)出版社 ,2021。 [8] 黎連業(yè)，張維，向東明 .防火墻及其應(yīng)用技術(shù) [M].北京：清華大學(xué)出版社 ,2021。 第 26 頁 共 27 頁 致 謝 本文是在韓斌老師的熱情關(guān)心和指導(dǎo)下完成的，真的十分感謝他，他淵博的知識和嚴(yán)謹(jǐn)?shù)闹螌W(xué)作風(fēng)使我受益匪淺，在我畢業(yè)設(shè)計期間給 了我巨大的幫助，耐心的認(rèn)真的回復(fù)我每一個問題，對我們十分的認(rèn)真負(fù)責(zé)，這次能夠順利完成本課題韓老師起到了極大的作用。在此向他表示我最衷心的感謝！ 感謝宋波老師和張磊同學(xué)在課題研究初期給予的幫助，在我做畢業(yè)設(shè)計的過程中兩位同樣給我了很大的幫助，正是在你們的幫助下課題才得以很好的展開，有了一個很好的開端！另外還要特別感謝 CSDN 網(wǎng)上的一些朋友們，在更大家的相互討論中使我對這個課題有了更加深刻的了解，也謝謝你們對我所遇到問題時給予的無私幫助。 當(dāng)然在論文完成過程中，本人還得到了其他老師和許多同學(xué)的熱心幫助，本人向他 們表示深深的謝意！ 最后向在百忙之中評審本文的各位專家、老師表示衷心的感謝！ 作者簡介 姓 名：龔俊杰 性別： 男 出生年月： 1984 年 9月 19 日 民族： 漢 Email: 第 26 頁 共 27 頁 聲 明 本論文的工作是 2021年 2 月至 2021年 6月在成都信息工程學(xué)院網(wǎng)絡(luò)工程系完成的。文中除了特別加以標(biāo)注地方外，不包含他人已經(jīng)發(fā)表或撰寫過的研究成果 ，也不包含為獲得成都信息工程學(xué)院或其他教學(xué)機構(gòu)的學(xué)位或證書而使用過的材料。除非另有說明，本文的工作是原始性工作。 關(guān)于學(xué)位論文使用權(quán)和研究成果知識產(chǎn)權(quán)的說明： 本人完全了解成都信息工程學(xué)院有關(guān)保管使用學(xué)位論文的規(guī)定，其中包括： （ 1）學(xué)校有權(quán)保管并向有關(guān)部門遞交學(xué)位論文的原件與復(fù)印件。 （ 2）學(xué)?？梢圆捎糜坝　⒖s印或其他復(fù)制方式保存學(xué)位論文。 （ 3）學(xué)?？梢詫W(xué)術(shù)交流為目的復(fù)制、贈送和交換學(xué)位論文。 （ 4）學(xué)校可允許學(xué)位論文被查閱或借閱。 （ 5）學(xué)?？梢怨紝W(xué)位論文的全部或部分內(nèi)容（保密學(xué)位論文在解密后遵守此 規(guī)定）。 除非另有科研合同和其他法律文書的制約，本論文的科研成果屬于成都信息工程學(xué)院。 特此聲明！ 作者簽名： 2021年 06月 1 日 第 26 頁 共 27 頁 Billy saw service with the infantry in Europe, and was taken prisoner by the Germans. After his honorable discharge from the Army in 1945, Billy again enrolled in the Ilium School of Optometry. During his senior year there, he became engaged to the daughter of the founder an d owner of the school, and then suffered a mild nervous collapse. He was treated in a veterans39。 hospital near Lake Placid, and was given shock treatments and released. He married his fianc 閑 , finished his education, and was set up in business in Ilium by his fatherinlaw. Ilium is a particularly good city for optometrists because the General Fe and Foundry Company is there. Every employee is required to own a pair of safety glasses, and to wear them in areas where manufacturing is going on. GFamp。F has sixtyeight thousand employees in Ilium. That calls for a lot of lenses and a lot of frames. Frames are where the money istion of coalmines was far distant and there was no dread of scarcity. There were still extensive mines to be worked in the two Americas. The manufactories, appropriated to so many different uses, lootives, steamers, gas works, amp。c., were not likely to fail for want of the mineral fuel。 but the consumption had so increased during the last few years, that certain beds had been exhausted even to their smallest veins. Now deserted, these mines perforated the ground with their useless shafts and forsaken galleries. This was exactly the case with the pits of Aberfoyle. Ten years before, the last butty had raised the last ton of coal from this colliery. The underground working stock, traction engines, trucks which run on rails along the galleries, subterranean tramways, frames to support the shaft, pipes in short, all that constituted the machinery of a mine had been brought up from its depths. The exhausted mine was like the body of a huge fantasticallyshaped mastodon, from which all the ans of life have been taken, and only the skeleton remains. Nothing was left but long wooden ladders, down the Yarrow shaft the s, carpenters, outside and inside laborers, women, children, and old men, all were collected in the great yard of the Dochart pit, formerly heaped with coal from the mine. Many of these families had existed for generations in the mine of old Aberfoyle。 they were now driven to seek the means of subsistence elsewhere, and they waited sadly to bid farewell to the engineer. James Starr stood upright, at the door of the vast shed in which he had for so many years superintended the powerful machines of the shaft. Simon Ford, the foreman of the Dochart pit, then fiftyfive years of age, and other managers and overseers, surrounded him. James Starr took off his hat. The miners, cap in hand, kept a profound silence. This farewell scene was of a touching character, not wanting in grandeur. My friends, said the engineer, the time has e for us to 第 26 頁 共 27 頁 separate. The Aberfoyle mines, which for so many years have united us in a mon work, are now exhausted. All our researches have not led to the discovery of a new vein, and the last block of coal has just been extracted from the Dochart pit. And in confirmation of his words, James Starr pointed to a lump of coal which had been kept at the bottom of a basket. This piece of coal, my friends, resumed James Starr, is like the last drop of blood which has flowed through the veins of the mine! We shall keep it, as the first fragment of coal is kept, which was extracted a hundre
