計(jì)算機(jī)基礎(chǔ)知識(shí)一端口編輯：菜鳥學(xué)院 發(fā)表日期:2007-03-0700:04一摘要端口是個(gè)網(wǎng)絡(luò)應(yīng)用中很重要的東西，相當(dāng)于“門”了。二什么是端口在Internet上，各主機(jī)間通過TCP/TP協(xié)議發(fā)送和接收數(shù)據(jù)報(bào)，各個(gè)數(shù)據(jù)報(bào)根據(jù)其目的主機(jī)的ip地址來進(jìn)行互聯(lián)網(wǎng)絡(luò)中的路由選擇?？梢姡褦?shù)據(jù)報(bào)順利的傳送到目的主機(jī)是沒有問題的。問題出在哪里呢?我們知道大多數(shù)操作系統(tǒng)都支持多程序(進(jìn)程)同時(shí)運(yùn)行，那么目的主機(jī)應(yīng)該把接收到的數(shù)據(jù)報(bào)傳送給眾多同時(shí)運(yùn)行的進(jìn)程中的哪一個(gè)呢？顯然這個(gè)問題有待解決，端口機(jī)制便由此被引入進(jìn)來。本地操作系統(tǒng)會(huì)給那些有需求的進(jìn)程分配協(xié)議端口(protocalport,即我們常說的端口),每個(gè)協(xié)議端口由一個(gè)正整數(shù)標(biāo)識(shí)，如：80,139,445,等等。當(dāng)目的主機(jī)接收到數(shù)據(jù)報(bào)后，將根據(jù)報(bào)文首部的目的端口號(hào)，把數(shù)據(jù)發(fā)送到相應(yīng)端口，而與此端口相對(duì)應(yīng)的那個(gè)進(jìn)程將會(huì)領(lǐng)取數(shù)據(jù)并等待下?組數(shù)據(jù)的到來。說到這里，端口的概念似乎仍然抽象，那么繼續(xù)跟我來,別走開。端口其實(shí)就是隊(duì)，操作系統(tǒng)為各個(gè)進(jìn)程分配了不同的隊(duì)，數(shù)據(jù)報(bào)按照目的端口被推入相應(yīng)的隊(duì)中，等待被進(jìn)程取用，在極特殊的情況下，這個(gè)隊(duì)也是有可能溢出的，不過操作系統(tǒng)允許各進(jìn)程指定和調(diào)整自己的隊(duì)的大小。不光接受數(shù)據(jù)報(bào)的進(jìn)程需要開啟它自己的端口，發(fā)送數(shù)據(jù)報(bào)的進(jìn)程也需要開啟端口，這樣，數(shù)據(jù)報(bào)中將會(huì)標(biāo)識(shí)有源端口，以便接受方能順利的回傳數(shù)據(jù)報(bào)到這個(gè)端口。三端口的分類在Internet±,按照協(xié)議類型分類，端口被分為TCP端口和UDP端口兩類，雖然他們都用正整數(shù)標(biāo)識(shí)，但這并不會(huì)引起歧義，比如TCP的80端口和UDP的80端口，因?yàn)閿?shù)據(jù)報(bào)在標(biāo)明端口的同時(shí)，還將標(biāo)明端口的類型。從端口的分配來看，端口被分為固定端口和動(dòng)態(tài)端口兩大類(一些教程還將極少被用到的高端口劃分為第三類：私有端口)：固定端口(0-1023)：使用集中式管理機(jī)制，即服從一個(gè)管理機(jī)構(gòu)對(duì)端口的指派，這個(gè)機(jī)構(gòu)負(fù)責(zé)發(fā)布這些指派。由于這些端口緊綁于一些服務(wù)，所以我們會(huì)經(jīng)常掃描這些端口來判斷對(duì)方是否開啟了這些服務(wù)，如TCP的21(ftp),80(http),139(netbios).UDP的7(echo).69(tftp)等等一些大家熟知的端口；動(dòng)態(tài)端口(1024—49151)：這些端口并不被固定的捆綁于某一服務(wù)，操作系統(tǒng)將這些端口動(dòng)態(tài)的分配給各個(gè)進(jìn)程，同一進(jìn)程兩次分配有可能分配到不同的端口。不過一些應(yīng)用程序并不愿意使用操作系統(tǒng)分配的動(dòng)態(tài)端口，他們有其自己的‘商標(biāo)性‘端口，如。icq客戶端的4000端口，木馬冰河的7626端口等都是固定而出名的。四端口在入侵中的作用有人曾經(jīng)把服務(wù)器比作房子，而把端口比作通向不同房間（服務(wù)）的門，如果不考慮細(xì)節(jié)的話，這是一個(gè)不錯(cuò)的比喻。入侵者要占領(lǐng)這間房子，勢(shì)必要破門而入（物理入侵另說）,那么對(duì)于入侵者來說，了解房子開了幾扇門，都是什么樣的門，門后面有什么東西就顯得至關(guān)重要。入侵者通常會(huì)用掃描器對(duì)目標(biāo)主機(jī)的端口進(jìn)行掃描，以確定哪些端口是開放的，從開放的端口，入侵者可以知道目標(biāo)主機(jī)大致提供了哪些服務(wù)，進(jìn)而猜測(cè)可能存在的漏洞，因此對(duì)端口的掃描可以幫助我們更好的了解目標(biāo)主機(jī)，而對(duì)于管理員，掃描木機(jī)的開放端口也是做好安全防范的第一步。五端口的相關(guān)工具1netstat-an的確，這并不是一個(gè)工具，但他是查看自己所開放端口的最方便方法，在and中輸入這個(gè)命令就可以了。如下：C:\>netstat-anActiveConnectionsProtoLocalAddressForeignAddressStateTCP:13:0LISTENINGTCP:44:0LISTENINGTCP:10:0LISTENINGTCP:102:0LISTENINGTCP:102:0LISTENINGTCP:337:0LISTENINGUDP:135UDP:445*.*UDP:1027UDP:1029*.*UDP:1030這是我沒上網(wǎng)的時(shí)候機(jī)器所開的端口，兩個(gè)135和445是固定端口，其余幾個(gè)都是動(dòng)態(tài)端口。2fport.exe和mport.exe這也是兩個(gè)命令行下查看本地機(jī)器開放端口的小程序，其實(shí)與netstat-an這個(gè)命令大同小異，只不過它能夠顯示打開端口的進(jìn)程，信息更多一些而已，如果你懷疑自己的奇怪端口可能是木馬，那就用他們查查吧。3activeport.exe（也稱aports.exe）還是用來查看本地機(jī)器開放端口的東東，除了具有上面兩個(gè)程序的全部功能外，他還有兩個(gè)更吸引人之處：圖形界面以及可以關(guān)閉端口。這對(duì)菜鳥來說是個(gè)絕對(duì)好用的東西，推薦使用喔。4superscan3.0它的大名你不會(huì)沒聽說過吧，純端口掃描類軟件中的N0.1,速度快而且可以指定掃描的端口，不多說了，絕對(duì)必備工具。六保護(hù)好自己的端口剛接觸網(wǎng)絡(luò)的朋友一般都對(duì)自己的端口很敏感，總怕自己的電腦開放了過多端口，更怕其中就有后門程序的端口，但由于對(duì)端口不是很熟悉，所以也沒有解決辦法，上起網(wǎng)來提心吊膽。其實(shí)保護(hù)自己的端口并不是那么難，只要做好下面幾點(diǎn)就行了：1）查看：經(jīng)常用命令或軟件查看本地所開放的端口，看是否有可疑端口；2）判斷：如果開放端口中有你不熟悉的，應(yīng)該馬上查找端口大全或木馬常見端口等資料（網(wǎng)上多的很），看看里面對(duì)你那個(gè)可疑端口的作用描述，或者通過軟件查看開啟此端口的進(jìn)程來進(jìn)行判斷；3）關(guān)閉：如果真是木馬端口或者資料中沒有這個(gè)端口的描述，那么應(yīng)該關(guān)閉此端口，你可以用防火墻來屏蔽此端口，也可以用本地連接一TCP/IP一高級(jí)一選項(xiàng)一TCP/IP篩選，啟用篩選機(jī)制來篩選端口；注意：判斷時(shí)候要慎重，因?yàn)橐恍﹦?dòng)態(tài)分配的端口也容易引起你多余的懷疑，這類端口一般比較低，且連續(xù)。還有，一些狡猾的后門軟件，他們會(huì)借用80等一些常見端口來進(jìn)行通信（穿透了防火墻），令人防不勝防，因此不輕易運(yùn)行陌生程序才是關(guān)鍵。下面我們?cè)敿?xì)介紹常見端口。常見端口表匯總1tcpmuxTCPPortServiceMultiplexer傳輸控制協(xié)議端口服務(wù)多路開關(guān)選擇器compressnetManagementUtilitycompressnetCompressionProcess5rjeRemoteJobEntry7echoEcho9discardDiscard11systatActiveUsers13daytimeDaytimeqotdQuoteoftheDaymspMessageSendProtocolchargenCharacterGeneratorcompressnet管理實(shí)用程序壓縮進(jìn)程遠(yuǎn)程作業(yè)登錄回顯丟棄在線用戶時(shí)間每日引用消息發(fā)送協(xié)議字符發(fā)生器
