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。
端口：23
服务：Telnet
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的防火墙常会看见大量发送到广播地址255.255.255.255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
服务：HTTP
说明：用于网页浏览。木马Executor开放此端口。
端口：99
服务：gram 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 -Version2
说明：
109端口是为POP2（Post Office Protocol Version2，邮局协议2）服务开放的，是用于接收邮件的。
端口：110
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rpc.mountd、NFS、rpc.statd、rpc.csmd、rpc.ttybd、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防火墙另一边与E-MAIL服务器的缓慢连接。许多防火墙支持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Exchange Server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：IMAP协议，和POP3协议一样是用来接收邮件的，但是它有它的特别和新颖之处，它是面向用户的，它和POP3协议的主要区别是：用户可以不用把所有的邮件内容全部下载，而是只下载邮件标题和发件人等基本信息，用户可以由标题等基本信息，去决定是否下载邮件全文，用户可以通过客户端的浏览器直接对服务器上的邮件进行操作（比如：打开阅读全文、丢进垃圾箱、永久删除、整理到某文件夹下、归档、）。再简单来说就是：浏览器用的IMAP协议（143端口）来为你接收邮件以及让你很方便的操作服务器上的邮件。邮件客户端用的POP3协议（110端口）来为你接收邮件的全部信息和全文内容保存到你的本地机器成为一个副本，你对邮件客户端上的副本邮件的任何操作都是在副本上，不干涉邮件服务器上为你保存的邮件原本。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
服务：[NULL]
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PhAse1.0、Stealth Spy、IniKiller开放此端口。
端口：568
服务：Membership DPA
说明：成员资格 DPA。
端口：569
服务：Membership MSN
说明：成员资格 MSN。
端口：635
服务：mountd
说明：Linux的mountd Bug。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（Secure Sockets layer）
端口：666
服务：Doom Id Software
说明：木马Attack FTP、Satanz Backdoor开放此端口
端口：993
服务：IMAP
说明：SSL（Secure Sockets layer）
端口：1001、1011
服务：[NULL]
说明：木马Silencer、WebEx开放1001端口。木马Doly Trojan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SQL session也用此端口和5000端口。
端口：1025、1033
服务：1025：network blackjack 1033：[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Streaming Audio Trojan、Psyber Stream Server、Voice开放此端口。
端口：1234、1243、6711、6776
服务：[NULL]
说明：木马SubSeven2.0、Ultors Trojan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：RPC client fixed port session queries
说明：RPC客户固定端口会话查询
端口：1503
服务：NetMeeting T.120
说明：NetMeeting T.120
端口：1524
服务：ingress
说明：许多攻击脚本将安装一个后门SHELL于这个端口，尤其是针对SUN系统中Sendmail和RPC服务漏洞的脚本。如果刚安装了防火墙就看到在这个端口上的连接企图，很可能是上述原因。可以试试Telnet到用户的计算机上的这个端口，看看它是否会给你一个SHELL。连接到600/pcserver也存在这个问题。
端口：1600
服务：issd
说明：木马Shivka-Burka开放此端口。
端口：1720
服务：NetMeeting
说明：NetMeeting H.233 call Setup。
端口：1731
服务：NetMeeting Audio Call Control
说明：NetMeeting音频调用控制。
端口：1807
服务：[NULL]
说明：木马SpySender开放此端口。
