可以看到这里开启了不少端口，也可以判断出目标机器是windows主机
访问80端口

接着尝试了目录扫描，没结果。。。。。。
爆破mysql账号密码，没结果。。。。
枚举SMB，没结果。。。。。。
爆破RDP，没结果。。。。。。
其他几个端口也多多少少看了下，但是依旧没有任何的收获。
查看了下nmap的说明，发现他默认只扫TCP
尝试扫描下udp端口

nmap -sU 10.10.55.207 -top-ports 20

这里看到161端口开放着snmp服务
简单网络管理协议(SNMP)被广泛用于计算机操作系统设备、网络设备等领域监测连接到网络上的设备是否有任何引起管理上关注的情况。在运行SNMP服务的设备上，若管理员配置不当运行默认团体名/弱口令访问,将导致敏感信息泄露。敏感不限于系统运行的进程、已安装的软件、系统存在的用户，运行的服务，端口情况等。通过这些信息，攻击者可以清晰的了解到设备整体情况，根据开放的端口和服务快速定位可入侵点，根据运行的进程名判断是否存在哪些防护软件，有什么bypass的方法。根据存在的用户名，可以大大提高爆破效率等等。

使用snmp默认密钥尝试攻击

snmp-check 10.10.81.105 -c public

但是没成功
