【正文】 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(shí)際。 并且認(rèn)識(shí) 到實(shí)際當(dāng)中的設(shè)計(jì)和思想上與的課程設(shè)計(jì)是有很大的差別的。實(shí)際涉及到生產(chǎn)的設(shè)計(jì)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(jì)是不完整的、不嚴(yán)謹(jǐn)?shù)?、是沒有考慮經(jīng)濟(jì)和使用價(jià)值為基礎(chǔ)的。而這一點(diǎn)恰恰是實(shí)際生活設(shè)計(jì)之中必須考慮的，也是很重要的。設(shè)計(jì)的目的就是經(jīng)濟(jì)又適用，達(dá)到實(shí)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(jì)效益。 在設(shè)計(jì)中主要是完成了對(duì)于網(wǎng)卡信息的獲取還有對(duì)于網(wǎng)絡(luò)數(shù)據(jù)包捕獲功能的實(shí)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(shí)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(shí)現(xiàn)對(duì)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(shí)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(shí)現(xiàn)對(duì)于數(shù)據(jù)包的阻塞拋棄這個(gè)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(gè)問題暫時(shí)還沒有解決的頭緒。關(guān)于這個(gè)幾個(gè)問題還有再繼續(xù)豐富一些別的功能我會(huì)繼續(xù)下去直到最后，爭(zhēng)取做的更好更具有使用意義， 最后， 這是第一次單獨(dú)完成這么大代碼量的編程，由于 經(jīng)驗(yàn)欠缺或者是其他方面的一些原因，這次的項(xiàng)目開發(fā)也存在一些不足，如 程序員邏輯比較混亂，一些簡(jiǎn)單的問題要通過一堆無 用代碼才能實(shí)現(xiàn)，不能以簡(jiǎn)潔有效的方式解決 ， 在以后的項(xiàng)目開發(fā)過程中會(huì)逐漸解決這些不足之處。 參考文獻(xiàn) [1] 黃維通 .Visual C++面向?qū)ο笈c可視化程序設(shè)計(jì) [M].北京：清華大學(xué)出版社 ,2021。 [2] ：協(xié)議 [M].北京：機(jī)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(qiáng) .C程序設(shè)計(jì) [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(jī)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(shí)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(jì)期間給 了我巨大的幫助，耐心的認(rèn)真的回復(fù)我每一個(gè)問題，對(duì)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(jì)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(gè)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(duì)這個(gè)課題有了更加深刻的了解，也謝謝你們對(duì)我所遇到問題時(shí)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(píng)審本文的各位專家、老師表示衷心的感謝！ 作者簡(jiǎn)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(jī)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(shí)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)校可以采用影印、縮印或其他復(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(zèng)送和交換學(xué)位論文。 （ 4）學(xué)?？稍试S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 lists. Really? I said, trying not to sound jubilant. I found out they wear this red scarf thing on their arm. It covers up Sitting Bull39。s horse. That is a problem, I said. Well, that39。s not all. My docent told me about your lunch. Did Grandma Karen really tell you you were right? Yes. Gosh! I didn39。t believe that part. Well, anyway, my docent said you wouldn39。t listen to her about how great menstruating is, that you all kept talking about the negative aspects of it, like bloating and cramps and crabbiness, and I said, 39。What are cramps?39。 and she said, 39。Menstrual bleeding frequently causes headaches and depression,39。 and I said, 39。Bleeding! ? Nobody ever said anything about bleeding!39。 Why didn39。t you tell me there was blood involved, Mother? I had, but I felt it wiser to keep silent. And you didn39。t say a word about its being painful. An uget. It was impossible to keep secrets when seven people lived in such a confined space. She knew for a fact, for instance, that what the Polo sisters did behind the closed doors of their adjoining rooms was still illegal in Alabama. They had all bounced around a lot, especially in the early months of the voyage. Gene was the only married crew member, and h e had taken care to announce quite early that he and his wife had an arrangement about such matters. Still, he had slept alone for a long time because the Polos had each other, Gaby didn39。t seem to care about sex at all, and Cirocco had been irresistibly drawn to Calvin Greene. Her persistence was such that Calvin eventually went to bed with her, not just once, but three times. It didn39。t get any better, so before he could sense her disappointment she had cooled the re lationship and let him pursue Gaby, the woman he had been drawn to from the first. Calvin was a general surgeon trained by NASA to be petent as ship39。s biologist and ecologist as well. He was blac k, but attached little importance to it, having been born and raised in O39。Neil One. He was also the only crew member who was taller than sirocco. She didn39。t think that had much to do with his appeal。 she had learned early to be indifferent to a man39。s height, since she like a big, soft asteroid. The analogy pleased her. Extending it, she watched the te rminator line crawl around her to bring the hills and valleys of her front into sunlight. Cirocco liked space, reading, and sex, not necessarily in that order. She had never been able to satisfactorily bine all three, but two was not bad. New games were possible in freefall, like the one they had been playing, no hands. T hey could use feet, mouths, knees, or shoulders to position each other. One had to be gentle and careful, but with slow bites and nips anything could be done, and in such an interesting way. All of them came to the hydroponics room from time to time. Ringmaster had seven private rooms, and they were as necessary as oxygen. But even Cirocco39。s cabin was crowded when two people were in it, and it *as at the bottom of the carousel. It took one act of love in freefall to make a bed seem as limiting as the back scat of a Chevrolet. 39。Why don39。t you turn this way a little? Bill asked. Can you give me a good reason? He showed her one, and she gave him a little more than he had asked for. Then she found herself with a little more than she had .asked for, but as usual, he kne would be easy to move it. Cirocco frowned. Just how big is it, then? The PoloAugust, she was almost sure it was August looked at her with that calm, strangely unsettling face. I should say about two or three kilometers. Po
