篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了linux查看端口及端口详解相关的知识，希望对你有一定的参考价值。
今天现场查看了TCP端口的占用情况，如下图
红色部分是IP，现场那边问我是不是我的程序占用了tcp的链接，，我远程登陆现场查看了一下，这种类型的tcp链接占用了400多个，，后边查了一下资料，说ESTABLISHED状态
ESTABLISHED的意思是建立连接。表示两台机器正在通信。 之后查找 ncube-lm 发现ncube-lm是一个端口，是nCube License Manager （即ncube管理的一个许可证明），意思是被允许，被认证开放的意思，，，
之后查看端口号 是1521 网络搜索1521 发现1521是Oracle默认开放的端口号，，，之后看第二个IP是干啥的，追索源头！......
下来先说一下在linux下怎么查看端口号的占用情况！
-
-
使用“netstat”命令，查看正在连接的端口【连接】列表信息。
-
使用“nestat -a”命令，查看所有服务端口【监听、连接】列表信息。
-
套接字的种类除了t（TCP）、u（UDP）之外，还有w（RAW）、x（UNIX）套接字。
-
使用" netstat -ap"查看所有服务端口和对应的程序名称。
-
接下来了解一下端口的详细情况！

以下是bingtang补充：
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。
??1 tcpmux 这显示有人在寻找SGI Irix机器。Irix是实现tcpmux的主要提供者，缺省情况下tcpmux在这种系统中被打开。Iris机器在发布时含有几个缺省的无密码的帐户，如lp, guest, uucp, nuucp, demos, tutor, diag, EZsetup, OutOfBox, 和4Dgifts。许多管理员安装后忘记删除这些帐户。因此Hacker们在Internet上搜索tcpmux并利用这些帐户。

以下是bingtang补充：
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。
??1 tcpmux 这显示有人在寻找SGI Irix机器。Irix是实现tcpmux的主要提供者，缺省情况下tcpmux在这种系统中被打开。Iris机器在发布时含有几个缺省的无密码的帐户，如lp, guest, uucp, nuucp, demos, tutor, diag, EZsetup, OutOfBox, 和4Dgifts。许多管理员安装后忘记删除这些帐户。因此Hacker们在Internet上搜索tcpmux并利用这些帐户。
??7 Echo 你能看到许多人们搜索Fraggle放大器时，发送到x.x.x.0和x.x.x.255的信息。常见的一种DoS攻击是echo循环（echo-loop），攻击者伪造从一个机器发送到另一个机器的UDP数据包，而两个机器分别以它们最快的方式回应这些数据包。另一种东西是由DoubleClick在词端口建立的TCP连接。有一种产品叫做“Resonate Global Dispatch”，它与DNS的这一端口连接以确定最近的路由。Harvest/squid cache将从3130端口发送UDP echo：“如果将cache的source_ping on选项打开，它将对原始主机的UDP echo端口回应一个HIT reply。”这将会产生许多这类数据包。
??11 sysstat 这是一种UNIX服务，它会列出机器上所有正在运行的进程以及是什么启动了这些进程。这为入侵者提供了许多信息而威胁机器的安全，如暴露已知某些弱点或帐户的程序。这与UNIX系统中“ps”命令的结果相似。再说一遍：ICMP没有端口，ICMP port 11通常是ICMP type=11。
??19 chargen 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知道连接关闭。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。由于服务器企图回应两个服务器之间的无限的往返数据通讯一个chargen和echo将导致服务器过载。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。
??21 ftp 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。Hackers或Crackers 利用这些服务器作为传送warez (私有程序) 和pr0n(故意拼错词而避免被搜索引擎分类)的节点。
??22 ssh PcAnywhere 建立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库的版本有不少漏洞。（建议在其它端口运行ssh）。还应该注意的是ssh工具包带有一个称为make-ssh-known-hosts的程序。它会扫描整个域的ssh主机。你有时会被使用这一程序的人无意中扫描到。UDP（而不是TCP）与另一端的5632端口相连意味着存在搜索pcAnywhere的扫描。5632（十六进制的0x1600）位交换后是0x0016（使进制的22）。
??23 Telnet 入侵者在搜索远程登陆UNIX的服务。大多数情况下入侵者扫描这一端口是为了找到机器运行的操作系统。此外使用其它技术，入侵者会找到密码。
??25 smtp 攻击者（spammer）寻找SMTP服务器是为了传递他们的spam。入侵者的帐户总被关闭，他们需要拨号连接到高带宽的e-mail服务器上，将简单的信息传递到不同的地址。SMTP服务器（尤其是sendmail）是进入系统的最常用方法之一，因为它们必须完整的暴露于Internet且邮件的路由是复杂的（暴露+复杂=弱点）。
??53 DNS Hacker或crackers可能是试图进行区域传递（TCP），欺骗DNS（UDP）或隐藏其它通讯。因此防火墙常常过滤或记录53端口。需要注意的是你常会看到53端口做为UDP源端口。不稳定的防火墙通常允许这种通讯并假设这是对DNS查询的回复。Hacker常使用这种方法穿透防火墙。
??67&68 Bootp和DHCP UDP上的Bootp/DHCP：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分配。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的“中间人”（man-in-middle）攻击。客户端向68端口（bootps）广播请求配置，服务器向67端口（bootpc）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。
??69 TFTP(UDP) 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。但是它们常常错误配置而从系统提供任何文件，如密码文件。它们也可用于向系统写入文件。
??79 finger Hacker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它机器finger扫描。
??98 linuxconf 这个程序提供linux boxen的简单管理。通过整合的HTTP服务器在98端口提供基于Web界面的服务。它已发现有许多安全问题。一些版本setuid root，信任局域网，在/tmp下建立Internet可访问的文件，LANG环境变量有缓冲区溢出。此外因为它包含整合的服务器，许多典型的HTTP漏洞可能存在（缓冲区溢出，历遍目录等）
??109 POP2 并不象POP3那样有名，但许多服务器同时提供两种服务（向后兼容）。在同一个服务器上POP3的漏洞在POP2中同样存在。
??110 POP3 用于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Hacker可以在真正登陆前进入系统）。成功登陆后还有其它缓冲区溢出错误。
??111 sunrpc portmap rpcbind Sun RPC PortMapper/RPCBIND。访问portmapper是扫描系统查看允许哪些RPC服务的最早的一步。常见RPC服务有：rpc.mountd, NFS, rpc.statd, rpc.csmd, rpc.ttybd, amd等。入侵者发现了允许的RPC服务将转向提供服务的特定端口测试漏洞。记住一定要记录线路中的daemon, IDS, 或sniffer，你可以发现入侵者正使用什么程序访问以便发现到底发生了什么。
??113 Ident auth 这是一个许多机器上运行的协议，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机器的信息（会被Hacker利用）。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，你将会看到许多这个端口的连接请求。记住，如果你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。许多防火墙支持在TCP连接的阻断过程中发回RST，着将回停止这一缓慢的连接。
??119 NNTP news 新闻组传输协议，承载USENET通讯。当你链接到诸如：news://comp.security.firewalls/. 的地址时通常使用这个端口。这个端口的连接企图通常是人们在寻找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。
??135 oc-serv MS RPC end-point mapper 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/或RPC的服务利用机器上的end-point mapper注册它们的位置。远端客户连接到机器时，它们查询end-point mapper找到服务的位置。同样Hacker扫描机器的这个端口是为了找到诸如：这个机器上运行Exchange Server吗？是什么版本？这个端口除了被用来查询服务（如使用epdump）还可以被用于直接攻击。有一些DoS攻击直接针对这个端口。
??137 NetBIOS name service nbtstat (UDP) 这是防火墙管理员最常见的信息。
??139 NetBIOS File and Print Sharing 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。在Internet上共享自己的硬盘是可能是最常见的问题。大量针对这一端口始于1999，后来逐渐变少。2000年又有回升。一些VBS（IE5 VisualBasic Scripting）开始将它们自己拷贝到这个端口，试图在这个端口繁殖。
??143 IMAP 和上面POP3的安全问题一样，许多IMAP服务器有缓冲区溢出漏洞运行登陆过程中进入。记住：一种Linux蠕虫（admw0rm）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被感染的用户。当RadHat在他们的Linux发布版本中默认允许IMAP后，这些漏洞变得流行起来。Morris蠕虫以后这还是第一次广泛传播的蠕虫。这一端口还被用于IMAP2，但并不流行。已有一些报道发现有些0到143端口的攻击源于脚本。
??161 SNMP(UDP) 入侵者常探测的端口。SNMP允许远程管理设备。所有配置和运行信息都储存在数据库中，通过SNMP客获得这些信息。许多管理员错误配置将它们暴露于Internet。Crackers将试图使用缺省的密码“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你的网络。Windows机器常会因为错误配置将HP JetDirect remote management软件使用SNMP。HP OBJECT IDENTIFIER将收到SNMP包。新版的Win98使用SNMP解析域名，你会看见这种包在子网内广播（cable modem, DSL）查询sysName和其它信息。
??162 SNMP trap 可能是由于错误配置
??177 xdmcp 许多Hacker通过它访问X-Windows控制台， 它同时需要打开6000端口。
??513 rwho 可能是从使用cable modem或DSL登陆到的子网中的UNIX机器发出的广播。这些人为Hacker进入他们的系统提供了很有趣的信息。
??553 CORBA IIOP (UDP) 如果你使用cable modem或DSL VLAN，你将会看到这个端口的广播。CORBA是一种面向对象的RPC（remote procedure call）系统。Hacker会利用这些信息进入系统。
??600 Pcserver backdoor 请查看1524端口。
一些玩script的孩子认为他们通过修改ingreslock和pcserver文件已经完全攻破了系统-- Alan J. Rosenthal.

??635 mountd Linux的mountd Bug。这是人们扫描的一个流行的Bug。大多数对这个端口的扫描是基于UDP的，但基于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（到底在哪个端口，需要在端口111做portmap查询），只是Linux默认为635端口，就象NFS通常运行于2049端口。
??1024 许多人问这个端口是干什么的。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，它们请求操作系统为它们分配“下一个闲置端口”。基于这一点分配从端口1024开始。这意味着第一个向系统请求分配动态端口的程序将被分配端口1024。为了验证这一点，你可以重启机器，打开Telnet，再打开一个窗口运行“natstat -a”，你将会看到Telnet被分配1024端口。请求的程序越多，动态端口也越多。操作系统分配的端口将逐渐变大。再来一遍，当你浏览Web页时用“netstat”查看，每个Web页需要一个新端口。
??1025，1026 参见1024
??1080 SOCKS 这一协议以管道方式穿过防火墙，允许防火墙后面的许多人通过一个IP地址访问Internet。理论上它应该只允许内部的通信向外达到Internet。但是由于错误的配置，它会允许Hacker/Cracker的位于防火墙外部的攻击穿过防火墙。或者简单地回应位于Internet上的计算机，从而掩饰他们对你的直接攻击。WinGate是一种常见的Windows个人防火墙，常会发生上述的错误配置。在加入IRC聊天室时常会看到这种情况。
??1114 SQL 系统本身很少扫描这个端口，但常常是sscan脚本的一部分。
??1243 Sub-7木马（TCP）
??1524 ingreslock 后门许多攻击脚本将安装一个后门Shell于这个端口（尤其是那些针对Sun系统中sendmail和RPC服务漏洞的脚本，如statd, ttdbserver和cmsd）。如果你刚刚安装了你的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。你可以试试Telnet到你的机器上的这个端口，看看它是否会给你一个Shell。连接到600/pcserver也存在这个问题。
??2049 NFS NFS程序常运行于这个端口。通常需要访问portmapper查询这个服务运行于哪个端口，但是大部分情况是安装后NFS运行于这个端口，Hacker/Cracker因而可以闭开portmapper直接测试这个端口。
??3128 squid 这是Squid HTTP代理服务器的默认端口。攻击者扫描这个端口是为了搜寻一个代理服务器而匿名访问Internet。你也会看到搜索其它代理服务器的端口：8000/8001/8080/8888。扫描这一端口的另一原因是：用户正在进入聊天室。其它用户（或服务器本身）也会检验这个端口以确定用户的机器是否支持代理。
??5632 pcAnywere 你会看到很多这个端口的扫描，这依赖于你所在的位置。当用户打开pcAnywere时，它会自动扫描局域网C类网以寻找可能得代理（译者：指agent而不是proxy）。Hacker/cracker也会寻找开放这种服务的机器，所以应该查看这种扫描的源地址。一些搜寻pcAnywere的扫描常包含端口22的UDP数据包。
??6776 Sub-7 artifact 这个端口是从Sub-7主端口分离出来的用于传送数据的端口。例如当控制者通过电话线控制另一台机器，而被控机器挂断时你将会看到这种情况。因此当另一人以此IP拨入时，他们将会看到持续的，在这个端口的连接企图。（译者：即看到防火墙报告这一端口的连接企图时，并不表示你已被Sub-7控制。）
??6970 RealAudio RealAudio客户将从服务器的6970-7170的UDP端口接收音频数据流。这是由TCP7070端口外向控制连接设置的。
??13223 PowWow PowWow 是Tribal Voice的聊天程序。它允许用户在此端口打开私人聊天的连接。这一程序对于建立连接非常具有“进攻性”。它会“驻扎”在这一TCP端口等待回应。这造成类似心跳间隔的连接企图。如果你是一个拨号用户，从另一个聊天者手中“继承”了IP地址这种情况就会发生：好象很多不同的人在测试这一端口。这一协议使用“OPNG”作为其连接企图的前四个字节。
??17027 Conducent 这是一个外向连接。这是由于公司内部有人安装了带有Conducent "adbot" 的共享软件。Conducent "adbot"是为共享软件显示广告服务的。使用这种服务的一种流行的软件是Pkware。有人试验：阻断这一外向连接不会有任何问题，但是封掉IP地址本身将会导致adbots持续在每秒内试图连接多次而导致连接过载：
机器会不断试图解析DNS名—ads.conducent.com，即IP地址216.33.210.40 ；216.33.199.77 ；216.33.199.80 ；216.33.199.81；216.33.210.41。（译者：不知NetAnts使用的Radiate是否也有这种现象）
机器会不断试图解析DNS名—ads.conducent.com，即IP地址216.33.210.40 ；216.33.199.77 ；216.33.199.80 ；216.33.199.81；216.33.210.41。（译者：不知NetAnts使用的Radiate是否也有这种现象）
??27374 Sub-7木马(TCP)
??30100 NetSphere木马(TCP) 通常这一端口的扫描是为了寻找中了NetSphere木马。
??31337 Back Orifice “elite” Hacker中31337读做“elite”/ei’li:t/（译者：法语，译为中坚力量，精华。即3=E, 1=L, 7=T）。因此许多后门程序运行于这一端口。其中最有名的是Back Orifice。曾经一段时间内这是Internet上最常见的扫描。现在它的流行越来越少，其它的木马程序越来越流行。
??31789 Hack-a-tack 这一端口的UDP通讯通常是由于"Hack-a-tack"远程访问木马（RAT, Remote Access Trojan）。这种木马包含内置的31790端口扫描器，因此任何31789端口到317890端口的连接意味着已经有这种入侵。（31789端口是控制连接，317890端口是文件传输连接）
??32770~32900 RPC服务 Sun Solaris的RPC服务在这一范围内。详细的说：早期版本的Solaris（2.5.1之前）将portmapper置于这一范围内，即使低端口被防火墙封闭仍然允许Hacker/cracker访问这一端口。扫描这一范围内的端口不是为了寻找portmapper，就是为了寻找可被攻击的已知的RPC服务。
??33434~33600 traceroute 如果你看到这一端口范围内的UDP数据包（且只在此范围之内）则可能是由于traceroute。参见本站相关部分。
