網(wǎng)安全實驗6(端口掃描)

鄭州大學(xué)信息工程學(xué)院09級計算機研究生實驗報告（六）課程名稱：網(wǎng)絡(luò)安全技術(shù)導(dǎo)論實驗地點：網(wǎng)絡(luò)實驗室實驗時間：2012年6月20日學(xué)生姓名：高燕燕學(xué)號：201112171993指導(dǎo)教師：翟光群一、實驗室名稱：網(wǎng)絡(luò)實驗室二、實驗項目名稱：端口掃描實驗（nmap）應(yīng)用三、實驗學(xué)時：2個學(xué)時四、實驗?zāi)康模菏煜map的使用及安裝；選擇幾臺肉雞，并使用-D標(biāo)志在命令行中指定它們。namp通過誘騙的IP地址來進行欺騙式端口掃描，可以同時看到不同的端口掃描，而只有一個是真實的，有效的保護了自己。五、實驗要求：對每個實驗要認真學(xué)習(xí)理解動手完成，對每個結(jié)果分析，并提交實驗報告六、試驗步驟1.安裝軟件nmap。進入主界面：2.在Target中輸入要掃描的目標(biāo)主機名，域名或者IP地址。在Profile中輸入要掃描的端口類型。下面是對目標(biāo)主機9的端口TCP以及UDP的掃描的詳細信息。下面是對目標(biāo)主機TCP端口掃面的結(jié)果：3.在cmd命令行中輸入nmap–d掃描目標(biāo)主機90兩臺主機。掃描結(jié)果如下所示：C:\DocumentsandSettings\Administrator>nmap-d90Winpcappresent,dynamiclinkedto:WinPcapversion4.1.2(packet.dllversion001),basedonlibpcapversion1.0branch1_0_rel0b(20091008)StartingNmap4.76()at2012-06-2111:02中國標(biāo)準(zhǔn)時間PORTS:Usingtop1000portsfoundopen(TCP:1000,UDP:0)---------------Timingreport---------------hostgroups:min1,max100000rtt-timeouts:init1000,min100,max10000max-scan-delay:TCP1000,UDP1000parallelism:min0,max0max-retries:10,host-timeout:0min-rate:0,max-rate:0---------------------------------------------InitiatingARPPingScanat11:02Scanning2hosts[1port/host]Packetcapturefilter(deviceeth0):arpandetherdsthost00:1F:C6:22:11:74CompletedARPPingScanat11:02,0.23selapsed(2totalhosts)Overallsendingrates:8.55packets/s,358.97bytes/s.mass_rdns:UsingDNSservermass_rdns:UsingDNSserverInitiatingParallelDNSresolutionof2hosts.at11:02mass_rdns:0.14s0/2[#:2,OK:0,NX:0,DR:0,SF:0,TR:2]CompletedParallelDNSresolutionof2hosts.at11:02,6.50selapsedDNSresolutionof2IPstook6.67s.Mode:Async[#:2,OK:0,NX:2,DR:0,SF:0,TR:4,CN:0]InitiatingSYNStealthScanat11:02Scanning2hosts[1000ports/host]Packetcapturefilter(deviceeth0):dsthost8and(icmpor((tcporudp)and(srchost9orsrchost0)))Discoveredopenport139/tcpon9Discoveredopenport139/tcpon0Discoveredopenport445/tcpon9Discoveredopenport445/tcpon0CompletedSYNStealthScanagainst9in10.94s(1hostleft)processDatatook62msCompletedSYNStealthScanat11:02,11.06selapsed(2000totalports)Overallsendingrates:363.82packets/s,16008.00bytes/s.Host9appearstobeup...good.Scannedat2012-06-2111:02:35中國標(biāo)準(zhǔn)時間for18sInterestingportson9:Notshown:998filteredportsReason:998no-responsesPORTSTATESERVICEREASON139/tcpopennetbios-ssnsyn-ack445/tcpopenmicrosoft-dssyn-ackMACAddress:00:1F:C6:22:0A:F8(AsustekComputer)Finaltimesforhost:srtt:0rttvar:1185to:100000Host0appearstobeup...good.Scannedat2012-06-2111:02:35中國標(biāo)準(zhǔn)時間for18sInterestingportson0:Notshown:998filteredportsReason:998no-responsesPORTSTATESERVICEREASON139/tcpopennetbios-ssnsyn-ack445/tcpopenmicrosoft-dssyn-ackMACAddress:00:1F:C6:22:11:95(AsustekComputer)Finaltimesforhost:srtt:10644rttvar:20538to:100000ReadfromC:\ProgramFiles\Nmap:nmap-mac-prefixesnmap-services.Nmapdone:2IPaddresses(2hostsup)scannedin19.66secondsRawpacketssent:4004(176.172KB)|Rcvd:18(788B)C:\Documents
