Google一下

The $WinREAgent folder is created during a Windows Update or upgrade and contains temporary files that allow you to recover Windows 10 if there are problems during the upgrade or update.

总结一下:

$WinREAgent 文件夹是WIndows10更新是产生的, 用于存放更新失败恢复的文件. 更新之后可以随意删除.

这是由于开发模式为 插件模式 的原因, 将其改为 小程序模式 即可.

探测目标主机操作系统类型

nmap aliyun.com -O
Starting Nmap 7.91 ( https://nmap.org ) at 2020-11-26 20:04 ?D1ú±ê×?ê±??
Nmap scan report for aliyun.com (106.11.248.144)
Host is up (0.025s latency).

PORT STATE SERVICE
80/tcp open http

在使用nmap扫描目标主机时:

nmap –osscan-guess www.minzhuokj.com
Starting Nmap 7.91 ( https://nmap.org ) at 2020-11-26 19:44 ?D1ú±ê×?ê±??
Nmap scan report for www.minzhuokj.com (39.96.251.199)
Host is up (0.025s latency).

PORT STATE SERVICE
1/tcp open tcpmux
3/tcp open compressnet
4/tcp open unknown
6/tcp open unknown
7/tcp open echo
9/tcp open discard
13/tcp open daytime
17/tcp open qotd
19/tcp open chargen
20/tcp open ftp-data
21/tcp open ftp
22/tcp open ssh
23/tcp open telnet
24/tcp open priv-mail
25/tcp open smtp
26/tcp open rsftp

发现 ssh 的 22 号端口开放, 于是尝试连接:

ssh.exe 39.96.251.199
ssh_exchange_identification: read: Connection reset

正常情况应该是提示输入用户名密码.
