Key feature of this implementation is use of multiple connections to overcome downsides of multiplexing many tunneled TCP connections in single SSH session. Just do whatever is needed to establish your tunnel and pass the socket to nnect(. rsp is a SSH client which implements SOCKS5 proxy feature of SSH protocol. Here are some other resources on how to tunnel through proxies. If "\r\n\r\n" in chunk: # we do not want to read too far ) # in worst case this loop will take 2 seconds if not response was received (sock.timeout) ttimeout(2) # quick hack - replace this with something better performing. scrcpy is an application for displaying and controlling your Android device through USB connection (or over TCP/IP). Sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)Ĭmd_connect = "CONNECT %s:%d HTTP/1.1\r\n\r\n"%target Logging.basicConfig(loglevel=logging.DEBUG)ĭef http_proxy_tunnel_connect(proxy, target,timeout=None): If there's SSL-Interception involved you could still try to tunnel it via ssl or as part of HTTP payload :) import paramiko If there's no DPI/SSL-Interception features involved, you should be fine. If this ultimately allows you to bypass your firewall depends on what kind of firewall is employed. Usually this is restricted to port 443 (hint: if you make your sshd listen on 443 this will work with most of the public proxies even thought I do not recommend to do this for interop and security reasons). The proxy and the sshd are running on the same host in my example but all you need is any proxy that allows you to CONNECT to your ssh port. This scenario works with a default installation of tinyproxy with Allow and ConnectPort 22 being set in /etc/nf. The result is a TCP tunnel over the established session that is usually used to tunnel SSL but can be used for any tcp based protocol. At first the connection to the proxy is established and the proxy is instructed to connect to localhost:22. You can use any pre-established session to paramiko via the sock parameter in nnect(hostname,username,password.,sock).īelow is a code-snippet that tunnels SSH via HTTP-Proxy-Tunnel (HTTP-CONNECT).
