反弹shell备忘录
Posted 篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了反弹shell备忘录相关的知识，希望对你有一定的参考价值。 简单理解，通常是我们主动发起请求，去访问服务器（某个IP的某个端口），比如我们常访问的web服务器： 接受端运行 bash python nc 不支持-e参数的时候 exec prel ruby 不依赖/bin/bash Windows JAVA 以上是关于反弹shell备忘录的主要内容，如果未能解决你的问题，请参考以下文章反弹shell备忘录
http(https)://ip:80，这是因为在服务器上面开启了80端口的监听，我们去访问它的时候，就会给我们建立连接。而现在所谓的反弹shell指的是反过来在我们自己的公网vps建立监听，然后让服务器反弹一个shell来连接我们自己的主机，然后我们就能通过反弹的shell去远程控制服务器了。nc -lvp port
