摘  要
網(wǎng)絡(luò)監(jiān)聽軟件是提供給網(wǎng)絡(luò)安全管理人員進(jìn)行安全管理的工具，可以用來(lái)監(jiān)視網(wǎng)絡(luò)的狀態(tài)、數(shù)據(jù)流動(dòng)情況以及網(wǎng)絡(luò)上傳輸?shù)男畔�，以獲取有用信息。作為黑客來(lái)說(shuō)，通過(guò)網(wǎng)絡(luò)監(jiān)聽可以獲取其所需信息（比如密碼等）；對(duì)黑客活動(dòng)和其他網(wǎng)絡(luò)犯罪進(jìn)行偵察、取證時(shí)，可以使用網(wǎng)絡(luò)監(jiān)聽技術(shù)來(lái)獲取必要的信息。因此，在目前研究和使用網(wǎng)絡(luò)監(jiān)聽技術(shù)及相關(guān)工具，對(duì)于防護(hù)網(wǎng)絡(luò)安全、打擊網(wǎng)絡(luò)犯罪具有重要的現(xiàn)實(shí)意義。
本局域網(wǎng)監(jiān)聽軟件主要利用Winpcap和Jpcap等工具進(jìn)行開發(fā)，使用Java語(yǔ)言在Eclipse 3.2環(huán)境下進(jìn)行開發(fā)。軟件主要實(shí)現(xiàn)了對(duì)網(wǎng)絡(luò)上的數(shù)據(jù)進(jìn)行監(jiān)聽，并分析出每一協(xié)議層的傳輸數(shù)據(jù)和協(xié)議層上主要字段的數(shù)據(jù)，然后將其顯示出來(lái)，同時(shí)進(jìn)行動(dòng)態(tài)更新；另外，添加了一些附加功能（指定對(duì)象監(jiān)聽、餅狀圖顯示、界面選擇等）。經(jīng)過(guò)測(cè)試與分析，說(shuō)明了該軟件運(yùn)行穩(wěn)定、可靠，具有一定的實(shí)際應(yīng)用價(jià)值。

Design and Development of LAN Monitoring Software
Abstract
Network-monitoring software is a secure management tool providing for the network security administrator. It can obtain useful information which monitors the network status, data flowing and information of network transmitting. Hackers can get the necessary information (such as password and so on) by means of network -monitoring. Hacker may gain the information which its needs (for instance password and so on) through the network-monitoring; Carrying on taking the reconnaissance and collecting the evidences about the hacker activity and other network crime, we may use the network monitor technology to gain the essential information. Therefore, studying and using network-monitoring technology and the correlate tool in present, it is important and practical significance for protecting network security and attacking network crime.
This local area network-monitoring software mainly is developed by using of Winpcap, Jpcap, the Java language and so on in the Eclipse 3.2 environment. This software mainly realizes monitoring the network data, analyzes the transmission data and the main field data on each protocol layer, and then demonstrates it, carries on the dynamic renewal. Simultaneously, this software increases some attachment functions (such as assigning object monitor, demonstrating of cake shape, the choice of surface etc.). After testing and the analyzing, which shows that this software is stable, reliable, and having the certain practical application value.

Key words: LAN; Network Monitoring; Protocol Layer; Data Transmission; Object Monitoring
