这是一个更加详细的扫描命令,其中:
- -T5 参数表示使用最快的扫描速度;
- -A 参数表示启用操作系统和服务版本检测等高级选项;
- -v 参数表示输出详细的扫描结果信息;
- 192.168.88.1 是被扫描的主机 IP 地址。
这个命令的作用是使用 SYN 扫描方式对主机的 22 端口进行扫描,并尝试检测该主机的操作系统和开放的服务版本等信息。同时,该命令使用了最快的扫描速度,并输出了详细的扫描结果信息。

31.使用Nmap进行端口扫描时,如何指定扫描特定的端口?( 1.5分) A.nmap -port 80 target B.nmap -P 80 target C.nmap -ports 80 target D.nmap -p 80 target
正确答案是 D. nmap -p 80 target。在使用 Nmap 进行端口扫描时,可以使用 -p 参数来指定要扫描的端口号。该参数后面可以跟一个端口号或一段端口范围,也可以使用逗号分隔多个端口号。例如,nmap -p 80 target 表示对目标主机进行端口扫描,只扫描 80 端口。如果要扫描多个端口,可以使用类似于 nmap -p 80,443,8080 target 的命令。注意,在指定端口时,需要根据具体的需要和情况进行选择,并遵守法律法规和道德规范,不得进行非法或未授权的端口扫描和攻击。
nmap -v scanme.nmap.org 扫描与 nmap -vv scanme.nmap.org 扫描的区别是什么
根据提供的引用[1],nmap是一款网络探测和安全审计工具。使用-v选项可以增加扫描的详细程度,使用-vv选项可以进一步增加详细程度。因此,nmap -v scanme.nmap.org扫描的详细程度比nmap -vv scanme.nmap.org扫描的详细程度要少。
下面是两个命令的示例:
1. nmap -v scanme.nmap.org扫描的输出示例:
