网络端口及其详解日期:2004年1月17日来源:不详作者:步云阅读次数:58321您现在的位置:首页电脑网络安全正文网络端口及其详解按端口号可分为3大类:(1)公认端口(WellKnownPorts):从0到1023,它们紧密绑定(binding)于一些服务。通常这些端口的通讯明确表明了某种服务的协议。例如:80端口实际上总是HTTP通讯。(2)注册端口(RegisteredPorts):从1024到49151。它们松散地绑定于一些服务。也就是说有许多服务绑定于这些端口,这些端口同样用于许多其它目的。例如:许多系统处理动态端口从1024左右开始。(3)动态和/或私有端口(Dynamicand/orPrivatePorts):从49152到65535。理论上,不应为服务分配这些端口。实际上,机器通常从1024起分配动态端口。但也有例外:SUN的RPC端口从32768开始。0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,当你试图使用一种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。1tcpmuxTCPPortServiceMultiplexer传输控制协议端口服务多路开关选择器2compressnetManagementUtilitycompressnet管理实用程序3compressnetCompressionProcess压缩进程5rjeRemoteJobEntry远程作业登录7echoEcho回显9discardDiscard丢弃11systatActiveUsers在线用户13daytimeDaytime时间17qotdQuoteoftheDay每日引用18mspMessageSendProtocol消息发送协议19chargenCharacterGenerator字符发生器20ftp-dataFileTransfer[DefaultData]文件传输协议(默认数据口)21ftpFileTransfer[Control]文件传输协议(控制)22sshSSHRemoteLoginProtocolSSH远程登录协议23telnetTelnet终端仿真协议24anyprivatemailsystem预留给个人用邮件系统25smtpSimpleMailTransfer简单邮件发送协议27nsw-feNSWUserSystemFENSW用户系统现场工程师29msg-icpMSGICPMSGICP31msg-authMSGAuthenticationMSG验证33dspDisplaySupportProtocol显示支持协议35anyprivateprinterserver预留给个人打印机服务37timeTime时间38rapRouteAccessProtocol路由访问协议39rlpResourceLocationProtocol资源定位协议41graphicsGraphics图形42nameserverWINSHostNameServerWINS主机名服务43nicnameWhoIs绰号whois服务44mpm-flagsMPMFLAGSProtocolMPM(消息处理模块)标志协议45mpmMessageProcessingModule[recv]消息处理模块46mpm-sndMPM[defaultsend]消息处理模块(默认发送口)47ni-ftpNIFTPNIFTP48auditdDigitalAuditDaemon数码音频后台服务49tacacsLoginHostProtocol(TACACS)TACACS登录主机协议50re-mail-ckRemoteMailCheckingProtocol远程邮件检查协议[未结束]51la-maintIMPLogicalAddressMaintenanceIMP(接口信息处理机)逻辑地址维护52xns-timeXNSTimeProtocol施乐网络服务系统时间协议53domainDomainNameServer域名服务器54xns-chXNSClearinghouse施乐网络服务系统票据交换55isi-glISIGraphicsLanguageISI图形语言56xns-authXNSAuthentication施乐网络服务系统验证57?anyprivateterminalaccess预留个人用终端访问58xns-mailXNSMail施乐网络服务系统邮件59anyprivatefileservice预留个人文件服务60Unassigned未定义61ni-mailNIMAILNI邮件?62acasACAServices异步通讯适配器服务63whois+whois+WHOIS+64coviaCommunicationsIntegrator(CI)通讯接口65tacacs-dsTACACS-DatabaseServiceTACACS数据库服务66sql*netOracleSQL*NETOracleSQL*NET67bootpsBootstrapProtocolServer引导程序协议服务端68bootpcBootstrapProtocolClient引导程序协议客户端69tftpTrivialFileTransfer小型文件传输协议70gopherGopher信息检索协议71netrjs-1RemoteJobService远程作业服务72netrjs-2RemoteJobService远程作业服务73netrjs-3RemoteJobService远程作业服务74netrjs-4RemoteJobService远程作业服务75anyprivatedialoutservice预留给个人拨出服务76deosDistributedExternalObjectStore分布式外部对象存储77anyprivateRJEservice预留给个人远程作业输入服务78vettcpvettcp修正TCP?79fingerFinger查询远程主机在线用户等信息80httpWorldWideWebHTTP全球信息网超文本传输协议81hosts2-nsHOSTS2NameServerHOST2名称服务82xferXFERUtility传输实用程序83mit-ml-devMITMLDevice模块化智能终端ML设备84ctfCommonTraceFacility公用追踪设备85mit-ml-devMITMLDevice模块化智能终端ML设备86mfcobolMicroFocusCobolMicroFocusCobol编程语言87anyprivateterminallink预留给个人终端连接88kerberosKerberosKerberros安全认证系统89su-mit-tgSU/MITTelnetGatewaySU/MIT终端仿真网关90dnsixDNSIXSecuritAttributeTokenMapDNSIX安全属性标记图91mit-dovMITDoverSpoolerMITDover假脱机92nppNetworkPrintingProtocol网络打印协议93dcpDeviceControlProtocol设备控制协议94objcallTivoliObjectDispatcherTivoli对象调度95supdupSUPDUP96dixieDIXIEProtocolSpecificationDIXIE协议规范97swift-rvf(SwiftRemoteVirturalFileProtocol)快速远程虚拟文件协议98tacnewsTACNewsTAC新闻协议99metagramMetagramRelay100newacct[unauthorizeduse]101=NICHostNameServer102=ISO-TSAP103=GenesisPoint-to-PointTransNet104=ACR-NEMADigitalImag.&Comm.300105=MailboxNameNameserver106=3COM-TSMUX3com-tsmux107=RemoteTelnetService108=SNAGatewayAccessServer109=PostOfficeProtocol-Version2110=PostOfficeProtocol-Version3111=SUNRPC112=McIDASDataTransmissionProtocol113=AuthenticationService114=AudioNewsMulticast115=SimpleFileTransferProtocol116=ANSAREXNotify117=UUCPPathService118=SQLServicessqlserv119=NetworkNewsTransferProtocol120=CFDPTKTcfdptkt121=EncoreExpeditedRemotePro.Call122=SMAKYNETsmakynet123=NetworkTimeProtocol124=ANSAREXTrader125=LocusPC-InterfaceNetMapSer126=UnisysUnitaryLogin127=LocusPC-InterfaceConnServer128=GSSXLicenseVerification129=PasswordGeneratorProtocol130=ciscoFNATIVE131=ciscoTNATIVE132=ciscoSYSMAINT133=StatisticsService134=INGRES-NETService135=LocationService136=PROFILENamingSystem137=NETBIOSNameService138=NETBIOSDatagramService139=NETBIOSSessionService140=EMFISDataService141=EMFISControlService142=Britton-LeeIDM143=InterimMailAccessProtocolv2144=NewSnews145=UAACProtocoluaac146=ISO-IP0iso-tp0147=ISO-IPiso-ip148=CRONUS-SUPPORT149=AED512EmulationService150=SQL-NETsql-net151=HEMShems152=BackgroundFileTransferProgram153=SGMPsgmp154=NETSCnetsc-prod155=NETSCnetsc-dev156=SQLService157=KNET/VMCommand/MessageProtocol158=PCMailServerpcmail-srv159=NSS-Routingnss-routing160=SGMP-TRAPSsgmp-traps161=SNMP162=SNMPTRAP163=CMIP/TCPManager164=CMIP/TCPAgent165=Xeroxxns-courier166=SiriusSystems167=NAMPnamp168=RSVDrsvd169=Send170=NetworkPostScript170=NetworkPostScript171=NetworkInnovationsMultiplex172=NetworkInnovationsCL/1173=Xyplexxyplex-mux174=MAILQ175=VMNET176=GENRAD-MUXgenrad-mux177=XDisplayManagerControlProtocol178=NextStepWindowServer179=BorderGatewayProtoc
