HTTP_Bridge es una útil que se utiliza para estar compuesta de dos partes, el servidor y un cliente.
Servidor
El servidor es solo un archivo php con poco de método para perdurar conexiones con estado usando sockets tcp y manejar las solicitudes http entrantes; por ahora, esta método solo funciona en servidores Linux.
Lo he probado con apache + mod_php, nginx + php-fpm y el servidor php incorporado (php -S)
Cliente
El cliente es un servidor Socks5 que audición las conexiones entrantes del cliente y empaqueta las cadenas de bytes y envía la solicitud http al servidor, una vez que obtiene la respuesta, escribe de nuevo al cliente.
Este cliente está escrito en óxido, he tomado prestada la implementación de Socks5 de este tesina v2socks, así que gracias a ylxdzsw
Ejemplos de
Se requieren Proxychains para ejecutar este ejemplo.
Sube el archivo del servidor hbserver/hbserver.php
a un servidor web en ejecución con soporte php, o ejecute uno lugar de la venidero guisa, esto generará un contenedor acoplable que audición en el puerto 8080.
docker ejecute –rm -it –net host –name apache-webserver -v “$ PWD / hbserver: / app -v“ $ PWD / tools / ports.conf: /etc/apache2/ports.conf ”webdevops / php-apache : 7.3
El cliente debe estar compilado, por lo que debe tener instalado un compilador de rust u obtener uno de aquí rustup
cliente cd &&
construcción de carga &&
./target/debug/hbsc
configurar proxychains para que apunte al puerto lugar socks5:
echo «socks5 127.0.0.1 1986» >> $ HOME / .proxychains / proxychains.conf
Con todo en su zona algunas pruebas:
