namp命令详解
我将用两个不同的部分来涵盖大部分NMAP的使用方法,这是nmap关键的第一部分。在下面的设置中,我使用两台已关闭防火墙的服务器来测试Nmap命令的工作情况。
- 192.168.0.100 – server1.tecmint.com
- 192.168.0.101 – server2.tecmint.com
NMAP命令用法
- # nmap [Scan Type(s)] [Options] {target specification}
如何在Linux下安装NMAP
现在大部分Linux的发行版本像Red Hat,CentOS,Fedoro,Debian和Ubuntu在其默认的软件包管理库(即Yum 和 APT)中都自带了Nmap,这两种工具都用于安装和管理软件包和更新。在发行版上安装Nmap具体使用如下命令。
- # yum install nmap [on Red Hat based systems]
- $ sudo apt-get install nmap [on Debian based systems]
一旦你安装了最新的nmap应用程序,你就可以按照本文中提供的示例说明来操作。
1. 用主机名和IP地址扫描系统
Nmap工具提供各种方法来扫描系统。在这个例子中,我使用server2.tecmint.com主机名来扫描系统找出该系统上所有开放的端口,服务和MAC地址。
使用主机名扫描
- [root@server1 ~]# nmap server2.tecmint.com
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 15:42 EST

- Nmap finished: 3 IP addresses (1 host up) scanned in 0.552 seconds
- You have new mail in /var/spool/mail/root
6. 从一个文件中扫描主机列表
如果你有多台主机需要扫描且所有主机信息都写在一个文件中,那么你可以直接让nmap读取该文件来执行扫描,让我们来看看如何做到这一点。
创建一个名为“nmaptest.txt ”的文本文件,并定义所有你想要扫描的服务器IP地址或主机名。
- [root@server1 ~]# cat > nmaptest.txt
- localhost
- server2.tecmint.com
- 192.168.0.101
接下来运行带“iL” 选项的nmap命令来扫描文件中列出的所有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
- Interesting ports on localhost.localdomain (127.0.0.1):

24.使用TCP ACK (PA)和TCP Syn (PS)扫描远程主机
有时候包过滤防火墙会阻断标准的ICMP ping请求,在这种情况下,我们可以使用TCP ACK和TCP Syn方法来扫描远程主机。
- [root@server1 ~]# nmap -PS 192.168.0.101
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 17:51 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: 1 IP address (1 host up) scanned in 0.360 seconds
- You have new mail in /var/spool/mail/root
25.使用TCP ACK扫描远程主机上特定的端口
- [root@server1 ~]# nmap -PA -p 22,80 192.168.0.101
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 18:02 EST
- Interesting ports on server2.tecmint.com (192.168.0.101):
- PORT STATE SERVICE
- 22/tcp open ssh
- 80/tcp open http
- MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
- Nmap finished: 1 IP address (1 host up) scanned in 0.166 seconds
- You have new mail in /var/spool/mail/root
26. 使用TCP Syn扫描远程主机上特定的端口
- [root@server1 ~]# nmap -PS -p 22,80 192.168.0.101
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 18:08 EST
- Interesting ports on server2.tecmint.com (192.168.0.101):
- PORT STATE SERVICE
- 22/tcp open ssh
- 80/tcp open http
- MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
- Nmap finished: 1 IP address (1 host up) scanned in 0.165 seconds
- You have new mail in /var/spool/mail/root
27.执行一次隐蔽的扫描
- [root@server1 ~]# nmap -sS 192.168.0.101
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 18:10 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: 1 IP address (1 host up) scanned in 0.383 seconds
- You have new mail in /var/spool/mail/root
28.使用TCP Syn扫描最常用的端口
- [root@server1 ~]# nmap -sT 192.168.0.101
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 18:12 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: 1 IP address (1 host up) scanned in 0.406 seconds
- You have new mail in /var/spool/mail/root
29.执行TCP空扫描以骗过防火墙
- [root@server1 ~]# nmap -sN 192.168.0.101
- Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-11 19:01 EST
- Interesting ports on server2.tecmint.com (192.168.0.101):
- Not shown: 1674 closed ports
- PORT STATE SERVICE
- 22/tcp open|filtered ssh
- 80/tcp open|filtered http
- 111/tcp open|filtered rpcbind
- 957/tcp open|filtered unknown
- 3306/tcp open|filtered mysql
- 8888/tcp open|filtered sun-answerbook
- MAC Address: 08:00:27:D9:8E:D7 (Cadmus Computer Systems)
- Nmap finished: 1 IP address (1 host up) scanned in 1.584 seconds
- You have new mail in /var/spool/mail/root
以上就是NMAP的基本使用,我会在第二部分带来NMAP更多的创意选项。至此,敬请关注我们,不要忘记分享您的宝贵意见。
