对于Linux系统/网络管理员的nmap的29个实例
================================================================================
**Nmap**亦称为**Network Mapper**(网络映射)是一个开源并且通用的用于Linux系统/网络管理员的工具。**nmap**用于**探索网络、执行安全扫描、网络核查**并且**找出开放端口**在远程机器上。它扫描在线主机、操作系统、包过滤和运行在远程主机的开放端口。
![Nmap 命令](http://www.tecmint.com/wp-content/uploads/2013/12/Nmap-Commands.png)
*Nmap 命令和示例*
我会在两个不同部分覆盖大部分**NMAP**的使用，这篇是nmap系列的第一部分(译注:原文为I’ll be covering most of NMAP usage in two different parts and this is the first part of nmap serious,这里serious可能为笔误，应该为series)。在这个步骤来，我有两个没有防火墙的服务器来测试nmap命令的工作。
- 192.168.0.100 – server1.tecmint.com
- 192.168.0.101 – server2.tecmint.com
### Nmap 命令使用 ###
# nmap [Scan Type(s)] [Options] {target specification}
### 如何在Linux上安装nmap ###
**Nmap** on distribution specific use the following command.
如今大部分Linux发行版像**Red Hat, CentOS, Fedoro, Debian** 和 **Ubuntu**已经包含了**nmap**在它们默认的包管理仓库中，名为[Yum][1] 和 [APT][2]。这两者用于安装和管理软件包和更新。为了在特定发行版上安装**nmap**，使用下面的命令。
# yum install nmap [on Red Hat based systems]
$ sudo apt-get install nmap [on Debian based systems]
一旦你已经安装了最新的nmap程序，你可以跟着这篇文章中的示例指令来。
### 1. 带主机名和IP地址扫描系统 ###
**nmap**工具提供了不同的方法来扫描一个系统。在这个例子中，我使用主机名为**server2.tecmint.com**的机器执行扫描来找出所有开放端口，服务和系统上的MAC地址。
#### 使用主机名扫描 ####
[root@server1 ~]# nmap server2.tecmint.com

Nmap finished: 1 IP address (1 host up) scanned in 0.465 seconds
You have new mail in /var/spool/mail/root
### 2. 使用"-v"选项扫描 ###
你可以看到带"-v"选项的命令给出了关于远程机器的更多信息。
[root@server1 ~]# nmap -v server2.tecmint.com
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 15:43 EST

#### 扫描多台主机 ####
你可以简单地通过在namap后写上它们的IP地址或者主机名来扫描多台主机。
[root@server1 ~]# nmap 192.168.0.101 192.168.0.102 192.168.0.103
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:06 EST
Interesting ports on server2.tecmint.com (192.168.0.101):
Not shown: 1674 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
111/tcp open rpcbind
957/tcp open unknown
3306/tcp open mysql
8888/tcp open sun-answerbook
MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 3 IP addresses (1 host up) scanned in 0.580 seconds
### 4. 扫描整个子网 ###
你可以通过**通配符**来使nmap扫描整个子网或者IP段。
[root@server1 ~]# nmap 192.168.0.*
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:11 EST
Interesting ports on server1.tecmint.com (192.168.0.100):
Not shown: 1677 closed ports
PORT STATE SERVICE
22/tcp open ssh
111/tcp open rpcbind
851/tcp open unknown
Interesting ports on server2.tecmint.com (192.168.0.101):
Not shown: 1674 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
111/tcp open rpcbind
957/tcp open unknown
3306/tcp open mysql
8888/tcp open sun-answerbook
MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 256 IP addresses (2 hosts up) scanned in 5.550 seconds
You have new mail in /var/spool/mail/root
从上面的输出你可以看到nmap扫描了整个子网，并给出了**网络**中**在线**主机的信息。
### 5. 使用IP地址的最后八位扫描多台主机 ###
你可以简单地通过指定IP地址的最后8位执行扫描多台主机。比如说，这里我在IP地址为192.168.0.101, 192.168.0.102 and 192.168.0.103的机器上执行了扫描。
[root@server1 ~]# nmap 192.168.0.101,102,103
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:09 EST
Interesting ports on server2.tecmint.com (192.168.0.101):
Not shown: 1674 closed ports
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
111/tcp open rpcbind
957/tcp open unknown
3306/tcp open mysql
8888/tcp open sun-answerbook
MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 3 IP addresses (1 host up) scanned in 0.552 seconds
You have new mail in /var/spool/mail/root
### 6. 从文件中扫描主机列表 ###
如果你有更多的自己要扫描，并且所有的主机细节写在一个文件中，你可以直接让namp读取它并执行扫描。让我们看看要怎么做。
创建一个名为“**nmaptest.txt**”的文本文件，并定义所有你想要扫描的IP地址或者服务器的主机名。
[root@server1 ~]# cat > nmaptest.txt
localhost
server2.tecmint.com
192.168.0.101
接着，带“**iL**”运行nmap命令来扫描文件中所有列出的IP地址。
[root@server1 ~]# nmap -iL nmaptest.txt
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-18 10:58 EST

MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 3 IP addresses (3 hosts up) scanned in 2.047 seconds
### 7. 扫描一个IP段 ###
在使用nmap扫描时，你可以指定一个IP段。
[root@server1 ~]# nmap 192.168.0.101-110
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:09 EST

MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 10 IP addresses (1 host up) scanned in 0.542 seconds
### 8. 排除远程主机扫描网络 ###
你可以在执行全网扫描的时候排除一些主机，或者在使用通配符扫描时使用“**–exclude**”选项。
[root@server1 ~]# nmap 192.168.0.* --exclude 192.168.0.100
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:16 EST

957/tcp open unknown
3306/tcp open mysql
8888/tcp open sun-answerbook
MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 255 IP addresses (1 host up) scanned in 5.313 seconds
You have new mail in /var/spool/mail/root
### 9. 扫描系统信息及路由跟踪 ###
使用nmap，你可以检测到运行在远程主机上的操作系统和版本。为了启用OS和版本检测，脚本扫描和跟踪路由，我们可以使用带 “**-A**” 选项使用nmap。
[root@server1 ~]# nmap -A 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:25 EST

在上面的输出中，你可以看到运行在远程主机上操作系统的TCP/IP指纹和更详细的运行在远程主机上的特定端口和服务。
### 10. 使用nmap启用系统检测 ###
使用选项“-O”和“-osscan-guess”同样帮助发现OS信息。
[root@server1 ~]# nmap -O server2.tecmint.com
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 17:40 EST

### 11. 扫描主机来检测防火墙 ###
下面的命令会在远程主机上执行扫描来检测主机上是否使用了任何包过滤器或者防火墙。
[root@server1 ~]# nmap -sA 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:27 EST

Nmap finished: 1 IP address (1 host up) scanned in 0.382 seconds
You have new mail in /var/spool/mail/root
### 12. 扫描主机以检查其受到防火墙保护 ###
为了扫描一个主机是否受到任何包过滤器软件或者防火墙保护。
[root@server1 ~]# nmap -PN 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:30 EST

Nmap finished: 1 IP address (1 host up) scanned in 0.399 seconds
### 13. 找出网络中在线主机 ###
在“**-sP**”选项的bang帮助下，我们可以简单地检测网络中的主机是否在线,带这个选项后nmap会跳过端口检测和其他事情。
[root@server1 ~]# nmap -sP 192.168.0.*
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-18 11:01 EST
Host server1.tecmint.com (192.168.0.100) appears to be up.
Host server2.tecmint.com (192.168.0.101) appears to be up.
MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
Nmap finished: 256 IP addresses (2 hosts up) scanned in 5.109 seconds
### 14. 执行快速扫描 ###
你可以带“**-F**”选项扫描所有列在nmap服务文件中的端口而留下其他端口。
[root@server1 ~]# nmap -F 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:47 EST

Nmap finished: 1 IP address (1 host up) scanned in 0.322 seconds
### 15. 找出nmap版本 ###
你可以使用“**-V**”选项找出运行在你机器上的nmap版本。
[root@server1 ~]# nmap -V
Nmap version 4.11 ( http://www.insecure.org/nmap/ )
You have new mail in /var/spool/mail/root
### 16. 连续扫描端口 ###
使用“**-r**”选项而不随机化。
[root@server1 ~]# nmap -r 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 16:52 EST

Nmap finished: 1 IP address (1 host up) scanned in 0.363 seconds
### 17. 打印主机接口及路由 ###
你可以使用nmap的“**–iflist**”选项来找出主机接口和路由信息。
[root@server1 ~]# nmap --iflist
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 17:07 EST
************************INTERFACES************************

**************************ROUTES**************************
DST/MASK DEV GATEWAY
192.168.0.0/0 eth0
169.254.0.0/0 eth0
在上面的输出中，你可以看到清单列出了连接到你系统中的接口和它们相应的路由。
### 18. 扫描特定端口 ###
nmap使用不同的选项来发现远程机器上的端口。你可以用“**-p**”选项指定你想扫描的端口，默认上，nmap只会扫描**TCP**端口。
[root@server1 ~]# nmap -p 80 server2.tecmint.com
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 17:12 EST

### 19. 扫描TCP端口 ###
你同样可以指定nmap扫描的端口类型和号码。
[root@server1 ~]# nmap -p T:8888,80 server2.tecmint.com
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 17:15 EST

### 21. 扫描多个端口 ###
You can also scan multiple ports using option “**-p**“.
[root@server1 ~]# nmap -p 80,443 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-18 10:56 EST

### 22. 扫描网络的端口范围 ###
You can scan ports with ranges using expressions.
你可以使用表达式扫描端口范围
[root@server1 ~]# nmap -p 80-160 192.168.0.101
### 23. 找出主机服务版本号 ###
我们可以使用“**-sV**”选项找出运行在远程主机的服务版本号。
[root@server1 ~]# nmap -sV 192.168.0.101
Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 17:48 EST

#### 24. 使用 TCP ACK (PA) 和 TCP Syn (PS) 扫描远程主机 ####
有时包过滤防火墙阻止了标准**ICMP**ping请求，在这个情况下，我们可以使用**TCP ACK**和**TCP Syn**方法来扫描远程主机。

这些就是目前**NMAP** 的用法，我会写出更有创造性的**NMAP**的第二部分(译注:原文为 I’ll be coming up more creative options of **NMAP** in our second part of this serious,这里serious可能为笔误，应该为series)。接着，不要走开也别忘了分享你们有价值的评论。
