些常见端口功能对照表
电脑常用端口对照表4847
端口：544 服务：【null】 说明：kerberoskshell 端口：548 服务：macintosh,fileservices(afp/ip) 说明：macintosh,文件服务。 端口：553 服务：corbaiiop（udp） 说明：使用cablemodem、dsl或vlan将会看到这个端口的广播。corba是一种面向对象的rpc系统。 入侵者可以利用这些信息进入系统。 端口：555 服务：dsf 说明：木马phase1.0、stealthspy、inikiller开放此端口。 端口：568 服务：membershipdpa 说明：成员资格dpa。 端口：569 服务：membershipmsn 说明：成员资格msn。 端口：635 服务：mountd 说明：linux的mountdbug。这是扫描的一个流行bug。大多数对这个端口的扫描是基于udp的，但 是基于tcp的mountd有所增加（mountd同时运行于两个端口）。记住mountd可运行于任何端口（到底是 哪个端口，需要在端口111做portmap查询），只是linux默认端口是635，就像nfs通常运行于2049端口 。 端口：636 服务：ldap 说明：ssl（securesocketslayer） 端口：666 服务：doomidsoftware 说明：木马attackftp、satanzbackdoor开放此端口 端口：993 服务：imap 说明：ssl（securesocketsla【null】 说明：木马silencer、webex开放1001端口。木马dolytrojan开放1011端口。 端口：1024 服务：reserved 说明：它是动态端口的开始，许多程序并不在乎用哪个端口连接网络，它们请求系统为它们分配 下一个闲置端口。基于这一点分配从端口1024开始。这就是说第一个向系统发出请求的会分配到 1024端口。你可以重启机器，打开telnet，再打开一个窗口运行natstat－a将会看到telnet被分配 1024端口。还有sqlsession也用此端口和5000端口。 端口：1025、1033 服务：1025：networkblackjack1033：【null】 说明：木马netspy开放这2个端口。 端口：1080 服务：socks 说明：这一协议以通道方式穿过防火墙，允许防火墙后面的人通过一个ip地址访问internet。理 论上它应该只允许内部的通信向外到达internet。但是由于错误的配置，它会允许位于防火墙外部的 攻击穿过防火墙。wingate常会发生这种错误，在加入irc聊天室时常会看到这种情况。 端口：1170 服务：【null】 说明：木马streamingaudiotrojan、psyberstreamserver、voice开放此端口。 端口：1234、1243、6711、6776 服务：【null】 说明：木马subseven2.0、ultorstrojan开放1234、6776端口。木马subseven1.0/1.9开放1243、 6711、6776端口。 端口：1245 服务：【null】 说明：木马vodoo开放此端口。 端口：1433 服务：sql 说明：microsoft的sql服务开放的端口。 端口：1492 服务：stone－design－1 说明：木马ftp99cmp开放此端口。 端口：1500 服务：rpcclientfixedportsessionqueries 说明：rpc客户固定端口会话查询
计算机常用端口对照表
如果有不明白的地方或者陌生的端口可以在这里查到。
以便于检查系统是否感染病毒或木马。
但是在有防火墙的情况下，一般的防火墙都是严格审核程序的网络连接的，所以会预先封闭所有的端口，有需要访问网络的程序会预先向防火墙提出申请，防火墙做出响应，并弹出提示，要求用户做出选择，这时候我们就要认真看了，是哪一个程序，在文件夹的哪一个位置，要做一个估计，陌生程序就更要检查。
这样才能不给恶意程序任何余地。
同时系统自动升级最好打开，或者定期到windows的微软网站下载系统更新程序，这样也非常有利于系统安全。
系统漏洞可能会使恶意程序通过系统漏洞绕过防火墙连接到网络。
以下端口只做研究之用（一般有了防火墙了以后，会有一定的保障了）端口：1服务：tcpmux说明：这显示有人在寻找sgi irix机器。
irix是实现tcpmux的主要提供者，默认情况下tcpmux在这种系统中被打开。
irix机器在发布是含有几个默认的无密码的帐户，如：ip、guest uucp、nuucp、demos 、tutor、diag、outofbox等。
许多管理员在安装后忘记删除这些帐户。
因此hacker在internet上搜索tcpmux并利用这些帐户。
端口：7服务：echo说明：能看到许多人搜索fraggle放大器时，发送到x.x.x.0和x.x.x.255的信息。
端口：19服务：character generator说明：这是一种仅仅发送字符的服务。
udp版本将会在收到udp包后回应含有**字符的包。
tcp连接时会发送含有**字符的数据流直到连接关闭。
hacker利用ip欺骗可以发动dos攻击。
伪造两个chargen服务器之间的udp包。
同样fraggle dos攻击向目标地址的这个端口广播一个带有伪造受害者ip的数据包，受害者为了回应这些数据而过载。
端口：21服务：ftp说明：ftp服务器所开放的端口，用于上传、下载。
最常见的攻击者用于寻找打开anonymous的ftp服务器的方法。
常见端口对照表
常见端口对照表端口：0服务：Reserved说明：通常用于分析操作系统。
这一方法能够工作是因为在一些系统中“0”是无效端口，当你试图使用通常的闭合端口连接它时将产生不同的结果。
一种典型的扫描，使用IP地址为0.0.0.0，设置ACK位并在以太网层广播。
端口：1服务：tcpmux说明：这显示有人在寻找SGI Irix机器。
Irix是实现tcpmux的主要提供者，默认情况下tcpmux在这种系统中被打开。
Irix机器在发布是含有几个默认的无密码的帐户，如：IP、GUEST UUCP、NUUCP、DEMOS 、TUTOR、DIAG、OUTOFBOX等。
许多管理员在安装后忘记删除这些帐户。
因此HACKER在INTERNET上搜索tcpmux并利用这些帐户。
端口：7服务：Echo说明：能看到许多人搜索Fraggle放大器时，发送到X.X.X.0和X.X.X.255的信息。
端口：19服务：Character Generator说明：这是一种仅仅发送字符的服务。
UDP版本将会在收到UDP包后回应含有垃圾字符的包。
TCP 连接时会发送含有垃圾字符的数据流直到连接关闭。
HACKER利用IP欺骗可以发动DoS攻击。
伪造两个chargen服务器之间的UDP包。
同样Fraggle DoS攻击向目标地址的这个端口广播一个带有伪造受害者IP 的数据包，受害者为了回应这些数据而过载。
端口：21服务：FTP说明：FTP服务器所开放的端口，用于上传、下载。
最常见的攻击者用于寻找打开anonymous的FTP 服务器的方法。
这些服务器带有可读写的目录。
木马Doly Trojan、Fore、Invisible FTP、WebEx、WinCrash 和Blade Runner所开放的端口。
端口：22服务：Ssh说明：PcAnywhere建立的TCP和这一端口的连接可能是为了寻找ssh。
这一服务有许多弱点，如果配置成特定的模式，许多使用RSAREF库的版本就会有不少的漏洞存在。

计算机各端口的作用
计算机主要端口总结21端口：21端口主要用于FTP（File Transfer Protocol，文件传输协议）服务。
23端口：23端口主要用于Telnet（远程登录）服务，是Internet 上普遍采用的登录和仿真程序。
25端口：25端口为SMTP（Simple Mail Transfer Protocol，简单邮件传输协议）服务器所开放，主要用于发送邮件，如今绝大多数邮件服务器都使用该协议。
53端口：53端口为DNS（Domain Name Server，域名服务器）服务器所开放，主要用于域名解析，DNS服务在NT系统中使用的最为广泛。
67、68端口：67、68端口分别是为Bootp服务的Bootstrap Protocol Server（引导程序协议服务端）和Bootstrap Protocol Client（引导程序协议客户端）开放的端口。
69端口：TFTP是Cisco公司开发的一个简单文件传输协议，类似于FTP。
79端口：79端口是为Finger服务开放的，主要用于查询远程主机在线用户、操作系统类型以及是否缓冲区溢出等用户的详细信息。
80端口：80端口是为HTTP（HyperText Transport Protocol，超文本传输协议）开放的，这是上网冲浪使用最多的协议，主要用于在WWW（World Wide Web，万维网）服务上传输信息的协议。
端口: 99服务：Metagram Relay说明：后门程序ncx99开放此端口。
端口：102服务：Message transfer agent(MTA)-X.400 over TCP/IP 说明：消息传输代理。
端口：109服务：Post Office Protocol -Version3说明：POP3服务器开放此端口，用于接收邮件，客户端访问服务器端的邮件服务。
POP3服务有许多公认的弱点。
关于用户名和密码交换缓冲区溢出的弱点至少有20个，这意味着入侵者可以在真正登陆前进入系统。

99端口：99端口是用于一个名为“MetagramRelay”（亚对策延时）的服务，该服务比较少见，一般是用不到的。
109、110端口：109端口是为POP2（PostOfficeProtocolVersion2，邮局协议2）服务开放的，110端口是为POP3（邮件协议3）服务开放的，POP2、POP3都是主要用于接收邮件的。
111端口：111端口是SUN公司的RPC（RemoteProcedureCall，远程过程调用）服务所开放的端口，主要用于分布式系统中不同计算机的内部进程通信，RPC在多种网络服务中都是很重要的组件。

这一方法能够工作是因为在一些系统中“0”是无效端口，当你试图使用通常的闭合端口连接它时将产生不同的结果。
一种典型的扫描，使用IP地址为，设置ACK位并在以太网层广播。
端口：1服务：tcpmux说明：这显示有人在寻找SGI Irix机器。
Irix是实现tcpmux的主要提供者，默认情况下tcpmux在这种系统中被打开。
Irix机器在发布是含有几个默认的无密码的帐户，如：IP、GUEST UUCP、NUUCP、DEMOS 、TUTOR、DIAG、OUTOFBOX等。
许多管理员在安装后忘记删除这些帐户。
因此HACKER在INTERNET上搜索tcpmux并利用这些帐户。
端口：7服务：Echo说明：能看到许多人搜索Fraggle放大器时，发送到和的信息。
端口：19服务：Character Generator说明：这是一种仅仅发送字符的服务。
UDP版本将会在收到UDP包后回应含有垃圾字符的包。
TCP连接时会发送含有垃圾字符的数据流直到连接关闭。
HACKER利用IP欺骗可以发动DoS攻击。
伪造两个chargen服务器之间的UDP包。
同样Fraggle DoS攻击向目标地址的这个端口广播一个带有伪造受害者IP的数据包，受害者为了回应这些数据而过载。
端口：21服务：FTP说明：FTP服务器所开放的端口，用于上传、下载。
最常见的攻击者用于寻找打开anonymous的FTP服务器的方法。
这些服务器带有可读写的目录。
木马DolyTrojan、Fore、Invisible FTP、WebEx、WinCrash和Blade Runner所开放的端口。
端口：22服务：Ssh说明：PcAnywhere建立的TCP和这一端口的连接可能是为了寻找ssh。
这一服务有许多弱点，如果配置成特定的模式，许多使用RSAREF库的版本就会有不少的漏洞存在。
端口：23说明：远程登录，入侵者在搜索远程登录UNIX的服务。
大多数情况下扫描这一端口是为了找到机器运行的操作系统。
还有使用其他技术，入侵者也会找到密码。
木马Tiny Telnet Server就开放这个端口。
端口：25服务：SMTP说明：SMTP服务器所开放的端口，用于发送邮件。
入侵者寻找SMTP服务器是为了传递他们的SPAM。
入侵者的帐户被关闭，他们需要连接到高带宽的E-MAIL服务器上，将简单的信息传递到不同的地址。
木马Antigen、Email Password Sender、Haebu Coceda、Shtrilitz Stealth、WinPC、WinSpy都开放这个端口。
端口：31服务：MSG Authentication说明：木马Master Paradise、Hackers Paradise开放此端口。
端口：42服务：WINS Replication说明：WINS复制端口：53服务：Domain Name Server（DNS）说明：DNS服务器所开放的端口，入侵者可能是试图进行区域传递（TCP），欺骗DNS（UDP）或隐藏其他的通信。
因此_blank">防火墙常常过滤或记录此端口。
端口：67服务：Bootstrap Protocol Server说明：通过DSL和Cable modem的_blank">防火墙常会看见大量发送到广播地址的数据。
这些机器在向DHCP服务器请求一个地址。
HACKER常进入它们，分配一个地址把自己作为局部路由器而发起大量中间人（man-in-middle）攻击。
客户端向68端口广播请求配置，服务器向67端口广播回应请求。
这种回应使用广播是因为客户端还不知道可以发送的IP地址。
端口：69服务：Trival File Transfer说明：许多服务器与bootp一起提供这项服务，便于从系统下载启动代码。
但是它们常常由于错误配置而使入侵者能从系统中窃取任何文件。
它们也可用于系统写入文件。
端口：79服务：Finger Server说明：入侵者用于获得用户信息，查询操作系统，探测已知的缓冲区溢出错误，回应从自己机器到其他机器Finger扫描。
端口：80说明：用于网页浏览。
木马Executor开放此端口。
端口：99服务：Metagram Relay说明：后门程序ncx99开放此端口。
端口：102服务：Message transfer agent(MTA) over TCP/IP说明：消息传输代理。
端口：109服务：Post Office Protocol -Version3说明：POP3服务器开放此端口，用于接收邮件，客户端访问服务器端的邮件服务。
POP3服务有许多公认的弱点。
关于用户名和密码交换缓冲区溢出的弱点至少有20个，这意味着入侵者可以在真正登陆前进入系统。
成功登陆后还有其他缓冲区溢出错误。
端口：110服务：SUN公司的RPC服务所有端口说明：常见RPC服务有、NFS、、、、amd等端口：113服务：Authentication Service说明：这是一个许多计算机上运行的协议，用于鉴别TCP连接的用户。
使用标准的这种服务可以获得许多计算机的信息。
但是它可作为许多服务的记录器，尤其是FTP、POP、IMAP、SMTP和IRC等服务。
通常如果有许多客户通过_blank">防火墙访问这些服务，将会看到许多这个端口的连接请求。
记住，如果阻断这个端口客户端会感觉到在_blank">防火墙另一边与E-MAIL服务器的缓慢连接。
许多_blank">防火墙支持TCP连接的阻断过程中发回RST。
这将会停止缓慢的连接。
端口：119服务：Network News Transfer Protocol说明：NEWS新闻组传输协议，承载USENET通信。
这个端口的连接通常是人们在寻找USENET服务器。
多数ISP限制，只有他们的客户才能访问他们的新闻组服务器。
打开新闻组服务器将允许发/读任何人的帖子，访问被限制的新闻组服务器，匿名发帖或发送SPAM。
端口：135服务：Location Service说明：Microsoft在这个端口运行DCE RPC end-point mapper为它的DCOM服务。
这与UNIX 111端口的功能很相似。
使用DCOM和RPC的服务利用计算机上的end-point mapper注册它们的位置。
远端客户连接到计算机时，它们查找end-point mapper找到服务的位置。
HACKER扫描计算机的这个端口是为了找到这个计算机上运行ExchangeServer吗？什么版本？还有些DOS攻击直接针对这个端口。
端口：137、138、139服务：NETBIOS Name Service说明：其中137、138是UDP端口，当通过网上邻居传输文件时用这个端口。
而139端口：通过这个端口进入的连接试图获得NetBIOS/SMB服务。
这个协议被用于windows文件和打印机共享和SAMBA。
还有WINS Regisrtation也用它。
端口：143服务：Interim Mail Access Protocol v2说明：和POP3的安全问题一样，许多IMAP服务器存在有缓冲区溢出漏洞。
记住：一种LINUX蠕虫（admv0rm）会通过这个端口繁殖，因此许多这个端口的扫描来自不知情的已经被感染的用户。
当REDHAT在他们的LINUX发布版本中默认允许IMAP后，这些漏洞变的很流行。
这一端口还被用于IMAP2，但并不流行。
端口：161服务：SNMP说明：SNMP允许远程管理设备。
所有配置和运行信息的储存在数据库中，通过SNMP可获得这些信息。
许多管理员的错误配置将被暴露在Internet。
Cackers将试图使用默认的密码public、private访问系统。
他们可能会试验所有可能的组合。
SNMP包可能会被错误的指向用户的网络。
端口：177服务：X Display Manager Control Protocol说明：许多入侵者通过它访问X-windows操作台，它同时需要打开6000端口。
端口：389服务：LDAP、ILS说明：轻型目录访问协议和NetMeeting Internet Locator Server共用这一端口。
端口：443服务：Https说明：网页浏览端口，能提供加密和通过安全端口传输的另一种HTTP。
端口：456服务：[NULL]说明：木马HACKERS PARADISE开放此端口。
端口：513服务：Login,remote login说明：是从使用cable modem或DSL登陆到子网中的UNIX计算机发出的广播。
这些人为入侵者进入他们的系统提供了信息。
端口：544说明：kerberos kshell端口：548服务：Macintosh,File Services(AFP/IP)说明：Macintosh,文件服务。
端口：553服务：CORBA IIOP （UDP）说明：使用cable modem、DSL或VLAN将会看到这个端口的广播。
CORBA是一种面向对象的RPC系统。
入侵者可以利用这些信息进入系统。
端口：555服务：DSF说明：木马、Stealth Spy、IniKiller开放此端口。
端口：568服务：Membership DPA说明：成员资格 DPA。
