nmap-7.94.tar

nmap是一款网络探测和安全审核工具。从官网下载nmap-7.94.tar源代码包后，可以按以下步骤进行编译和安装：

1. 解压源代码包

   tar zxvf nmap-7.94.tar.gz

2. 进入解压目录

   cd nmap-7.94

3. 配置环境

   ./configure

如果想要启用一些高级功能，可以使用以下命令：

   ./configure --with-zenmap --with-ncat --with-openssl=/usr/local/openssl

其中，--with-zenmap指定安装Zenmap，--with-ncat指定安装ncat，--with-openssl指定使用指定路径下的openssl库。

4. 编译

   make

5. 安装

   make install

6. 确认安装是否成功

   nmap --version

如果成功安装，会输出nmap的版本信息。

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：

2. nmap -vv scanme.nmap.org扫描的输出示例：

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核工具。它可以用来扫描网络主机，确定哪些主机在运行，哪些服务在运行以及哪些防火墙在运行。nmap还可以确定主机的操作系统和应用程序版本等信息。

根据提供的引用，nmap的-v选项可以增加扫描的详细程度，而-vv选项则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扫描的详细程度要低。
