计算机端口详细信息

摘要

端口在网络应用中是非常重要的，相当于“门”。

二 什么是端口

在 Internet上，各主机间通过TCP/TP协议发送和接收数据报，各个数据报根据其目的主机的ip地址来进行互联网络中的路由选择。可见，把数据报顺 利的传送到目的主机是没有问题的。问题出在哪里呢?我们知道大多数操作系统都支持多程序（进程）同时运行，那么目的主机应该把接收到的数据报传送给众多同 时运行的进程中的哪一个呢？显然这个问题有待解决，端口机制便由此被引入进来。

本地操作系统会给那些有需求的进程分配协议端口 （protocal port，即我们常说的端口），每个协议端口由一个正整数标识，如：80，139，445，等等。当目的主机接收到数据报后，将根据报文首部的目的端口 号，把数据发送到相应端口，而与此端口相对应的那个进程将会领取数据并等待下一组数据的到来。说到这里，端口的概念似乎仍然抽象，那么继续跟我来，别走 开。

端口其实就是队，操作系统为各个进程分配了不同的队，数据报按照目的端口被推入相应的队中，等待被进程取用，在极特殊的情况下，这个队也是有可能溢出的，不过操作系统允许各进程指定和调整自己的队的大小。

不光接受数据报的进程需要开启它自己的端口，发送数据报的进程也需要开启端口，这样，数据报中将会标识有源端口，以便接受方能顺利的回传数据报到这个端口。

三 端口的分类

在Internet上，按照协议类型分类，端口被分为TCP端口和UDP端口两类，虽然他们都用正整数标识，但这并不会引起歧义，比如TCP的80端口和UDP的80端口，因为数据报在标明端口的同时，还将标明端口的类型。

从端口的分配来看，端口被分为固定端口和动态端口两大类（一些教程还将极少被用到的高端口划分为第三类：私有端口）：

固定端口（0－1023）：

使用集中式管理机制，即服从一个管理机构对端口的指派，这个机构负责发布这些指派。由于这些端口紧绑于一些服务，所以我们会经常扫描这些端口来判断对方 是否开启了这些服务，如TCP的21（ftp），80（http），139（netbios），UDP的7（echo），69（tftp）等等一些大家熟 知的端口；

动态端口（1024－49151）：

这些端口并不被固定的捆绑于某一服务，操作系统将这些端口动态的分配给各个进程， 同一进程两次分配有可能分配到不同的端口。不过一些应用程序并不愿意使用操作系统分配的动态端口，他们有其自己的‘商标性’端口，如oicq客户端的 4000端口，木马冰河的7626端口等都是固定而出名的。

四 端口在入侵中的作用

有人曾经把服务器比作房子，而把端口比作通向不同房间（服务）的门，如果不考虑细节的话，这是一个不错的比喻。入侵者要占领这间房子，势必要破门而入（物理入侵另说），那么对于入侵者来说，了解房子开了几扇门，都是什么样的门，门后面有什么东西就显得至关重要。

入侵者通常会用扫描器对目标主机的端口进行扫描，以确定哪些端口是开放的，从开放的端口，入侵者可以知道目标主机大致提供了哪些服务，进而猜测可能存在 的漏洞，因此对端口的扫描可以帮助我们更好的了解目标主机，而对于管理员，扫描本机的开放端口也是做好安全防范的第一步。

五 端口的相关工具

1 netstat -an

的确，这并不是一个工具，但他是查看自己所开放端口的最方便方法，在cmd中输入这个命令就可以了。如下：

C:/>netstat -an

Active Connections

Proto Local Address Foreign Address State

TCP 0.0.0.0:135 0.0.0.0:0 LISTENING

TCP 0.0.0.0:445 0.0.0.0:0 LISTENING

TCP 0.0.0.0:1025 0.0.0.0:0 LISTENING

TCP 0.0.0.0:1026 0.0.0.0:0 LISTENING

TCP 0.0.0.0:1028 0.0.0.0:0 LISTENING

TCP 0.0.0.0:3372 0.0.0.0:0 LISTENING

UDP 0.0.0.0:135 *:*

UDP 0.0.0.0:445 *:*

UDP 0.0.0.0:1027 *:*

UDP 127.0.0.1:1029 *:*

UDP 127.0.0.1:1030 *:*

这是我没上网的时候机器所开的端口，两个135和445是固定端口，其余几个都是动态端口。

2 和m

这也是两个命令行下查看本地机器开放端口的小程序，其实与netstat -an这个命令大同小异，只不过它能够显示打开端口的进程，信息更多一些而已，如果你怀疑自己的奇怪端口可能是木马，那就用他们查查吧。

3 active（也称a）

还是用来查看本地机器开放端口的东东，除了具有上面两个程序的全部功能外，他还有两个更吸引人之处：图形界面以及可以关闭端口。这对菜鸟来说是个绝对好用的东西，推荐使用喔。

4

它的大名你不会没听说过吧，纯端口扫描类软件中的NO.1，速度快而且可以指定扫描的端口，不多说了，绝对必备工具。

六 保护好自己的端口

刚接触网络的朋友一般都对自己的端口很敏感，总怕自己的电脑开放了过多端口，更怕其中就有后门程序的端口，但由于对端口不是很熟悉，所以也没有解决办法，上起网来提心吊胆。其实保护自己的端口并不是那么难，只要做好下面几点就行了：

1) 查看：经常用命令或软件查看本地所开放的端口，看是否有可疑端口；

2) 判断：如果开放端口中有你不熟悉的，应该马上查找端口大全或木马常见端口等资料（网上多的很），看看里面对你那个可疑端口的作用描述，或者通过软件查看开启此端口的进程来进行判断；

3) 关闭：如果真是木马端口或者资料中没有这个端口的描述，那么应该关闭此端口，你可以用防火墙来屏蔽此端口，也可以用本地连接－TCP/IP－高级－选项－TCP/IP筛选，启用筛选机制来筛选端口；

注意：判断时候要慎重，因为一些动态分配的端口也容易引起你多余的怀疑，这类端口一般比较低，且连续。还有，一些狡猾的后门软件，他们会借用80等一些常见端口来进行通信（穿透了防火墙），令人防不胜防，因此不轻易运行陌生程序才是关键。
