rtcp.py @desc: 利用python的socket端口转发,用于远程维护。 如果连接不到远程,会sleep 36s,最多尝试200(即两小时)。 @usage: ./rtcp.py stream1 stream2 stream为:l:port或c:host:port l:port表示监听指定的本地端口 c:host:port表示监听远程指定的端口 使用场景: 一: A服务器在内网,公网无法直接访问这台服务器,但是A服务器可以联网访问公网的B服务器(假设IP为222.2.2.2)。 我们也可以访问公网的B服务器。我们的目标是访问A服务器的22端口。那么可以这样: 1. 在B服务器上运行: ./rtcp.py l:10001 l:10002 表示在本地监听了10001与10002两个端口,这样,这两个端口就可以互相传输数据了。 2. 在A服务器上运行: ./rtcp.py c:localhost:22 c:222.2.2.2:10001 表示连接本地的22端口与B服务器的10001端口,这两个端口也可以互相传输数据了。 3. 然后我们就可以这样来访问A服务器的22端口了: ssh 222.2.2.2 -p 10002 原理很简单,这个命令执行后,B服务器的10002端口接收到的任何数据都会传给10001端口,此时,A服务器是连接了B服务器的10001端口的,数据就会传给A服务器,最终进入A服务器的22端口。 二: 不用更多举例了,rtcp.py的l与c两个参数可以进行灵活的两两组合,多台服务器之间只要搞明白数据流方向,那么就能满足很多场景的需求。 @author: watercloud, zd, knownsec team @web: www.knownsec.com, blog.knownsec.com
