端口号的作用及常见端口号用途

在网络技术中，端口（Port）大致有两种意思：一是物理意义上的端口，比如，ADSLModem、集线器、交换机、路由器用于连接其他网络设备的接口，如RJ-45端口、SC端口等等。二是逻辑意义上的端口，一般是指TCP/IP协议中的端口，端口号的范围从0到65535，比如用于浏览网页服务的80端口，用于FTP服务的21端口等等。我们这里将要介绍的就是逻辑意义上的端口。那么TCP/IP协议中的端口指的是什么呢？如果把IP地址比作一间房子，端口就是出入这间房子的门。真正的房子只有几个门，但是一个IP地址的端口可以有65536个之多！端口是通过端口号来标记的，端口号只有整数，范围是从0到65535.端口有什么用呢？我们知道，一台拥有IP地址的主机可以提供许多服务，比如Web服务、FTP服务、SMTP服务等，这些服务完全可以通过1个IP地址来实现。那么，主机是怎样区分不同的网络服务呢？显然不能只靠IP地址，因为IP地址与网络服务的关系是一对多的关系。实际上是通过“IP地址+端口号”来区分不同的服务的。服务器一般都是通过知名端口号来识别的。例如，对于每个TCP/IP实现来说，FTP服务器的TCP端口号都是21，每个Telnet服务器的TCP端口号都是23，每个TFTP(简单文件传送协议)服务器的UDP端口号都是69.任何TCP/IP实现所提供的服务都用知名的1～1023之间的端口号。这些知名端口号由Internet号分配机构（InternetAignedNumbersAuthority,IANA）来管理。IP协议是由TCP、UDP、ARP、ICMP等一系列子协议组成的。其中，主要用来做传输数据使用的是TCP和UDP协议。在TCP和UDP协议中，都有端口号的概念存在。端口号的作用，主要是区分服务类别和在同一时间进行多个会话。7781=accu-lmgraccu-lmgr7789=ICQKiller7932=DataResourceManager7933=BusineRulesManager7999=irdmi2iRDMI28000=irdmiiRDMI8032=pro-edProEd8400=cvdcvd8401=sabarsdsabarsd8402=abarsdabarsd8403=admindadmind8450=npmpnpmp8473=vp2pVitualPointtoPoint8888=NewsEDGEserver8889=DesktopDataTCP18890=DesktopDataTCP28891=NESSapplication

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TinyTelnetServer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、EmailPawordSender、HaebuCoceda、ShtrilitzStealth、WinPC、WinSpy都开放这个端口。端口：80服务：HTTP说明：用于网页浏览。木马Executor开放此端口。端口：109服务：PostOfficeProtocol-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：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。6253/udpCRIP#
