步骤 3使用基本语法
从上一步可以看出，Nikto 有很多选项，但出于我们的目的，我们将坚持使用基本语法，如下所示。我们将<IP 或主机名>替换为实际的 IP 地址或主机名，不带尖括号。
如果我们知道它是我们要定位的 SSL 站点，我们可以在 Nikto 中指定它，通过在命令末尾添加 -ssl 来节省一些扫描时间。
nikto -h <IP or hostname> -ssl
步骤 4扫描启用了 SSL 的网站
例如，让我们从扫描 pbs.org 开始，以查看 Nikto 扫描将显示的一些类型的信息。在它连接到端口 443 后，我们看到有一些关于密码的有用信息以及其他详细信息的列表，例如服务器是 Nginx，但这里没有很多有趣的数据对我们来说。
nikto -h pbs.org -ssl

步骤 5扫描 IP 地址
现在我们执行了网站的快速扫描，让我们尝试在本地网络上使用 Nikto 来查找嵌入式服务器，例如路由器的登录页面或另一台计算机上的 HTTP 服务，而这些服务器只是一个没有网站的服务器。首先，让我们使用 ifconfig 查找我们的 IP 地址.
Starting Nmap 7.60 ( https://nmap.org ) at 2018-12-06 00:43 PST

有一个不错的小技巧可以将所有启动的主机直接发送到 Nikto 进行扫描。我们使用 cat 来读取存储在 nullbyte.txt 文档中的输出（或任何您命名的文档）。然后，有一个awk，一个Linux工具，可以帮助搜索以下模式，其中Up表示主机已启动，打印$ 2表示为每个单词打印出该行中的第二个单词，即仅IP地址。然后，我们将该数据发送到一个名为 targetIP.txt（或任何您想命名的文件）的新文件。
这对 Nikto 来说是完美的，因为它可以轻松解释这样的文件。因此，我们可以使用以下命令将此输出发送到 Nikto。
nikto -h targetIP.txt
结果看起来类似于我们在执行SSL扫描时得到的结果。
步骤 6扫描 HTTP 网站
我们已经扫描了一个安全的网站和本地网络上的 IP 地址，现在是时候使用端口 80 来追踪不安全的 Web 域了。在本例中，我使用的是“afl.com.au”，在我执行此扫描时未使用 SSL。
nikto -h www.afl.com.au
