$ ssh -o "Prox圜ommand=nc -X connect -x some-proxy:$proxy_port %h %p" To open a connection using the openbsd netcat version: Install the openbsd-netcat package from the official repositories. Prox圜ommand /path/to/proxytunnel -p :8080 -u user -s password -d :443 Using openbsd-netcat It can be Installed with the proxytunnel package from the official repositories.Īn example for using it with OpenSSH, to eventually connect to, is having the following content: The proxy connection is used to tunnel another protocol, for example SSH through a HTTPS connection. ProxyTunnel "is a program that connects stdin and stdout to a server somewhere on the network, through a standard HTTP(S) proxy". You can now use localhost:8888 as a SOCKS proxy. Note: As SSH thinks it is connecting to localhost it will not recognize the fingerprint and display a warning. If you do not have any web server listening on port 80 you can do: If you already have a web server listening on port 80 you are probably going to want to create a virtual host and tell your web server to proxy request to the hts server. One limitation of httptunnel is it explicitly can not handle HTTPS. If WWW access is allowed through a HTTP proxy, it is possible to use httptunnel and, say, telnet or PPP to connect to a computer outside the firewall. This can be useful for users behind restrictive firewalls. The HTTP requests can be sent via an HTTP proxy if so desired. Httptunnel, available in the official repositories as httptunnel, creates a bidirectional virtual data connection tunneled in HTTP requests. Now, git should be able to tunnel successfully through the HTTP proxy. When git sees the environment variable GIT_PROXY_COMMAND set, it will run the command in $GIT_PROXY_COMMAND and use the program's stdin and stdout, instead of a network socket.Ĭreate a script file corkscrewtunnel.sh #! /bin/bashĬorkscrew proxyhost proxyport GIT_PROXY_COMMAND export GIT_PROXY_COMMAND= path-to-corkscrewtunnel.sh However, git can be made to tunnel through HTTP proxies using utilities such as corkscrew. Restrictive corporate firewalls typically block the port that git uses. Which creates a SOCKS proxy on localhost:$port. Ssh -ND $port -o "Prox圜ommand corkscrew $proxy_ip_or_domain_name $proxy_port $destination_ip_or_domain_name $destination_port" Ssh -o "Prox圜ommand corkscrew $proxy_ip_or_domain_name $proxy_port $destination_ip_or_domain_name $destination_port"īut that just opens a shell yet what we want is a SOCKS tunnel, so we do this: Opening an SSH connection is pretty simple: Note: If your proxy does not support the HTTP Connect method, see the other methods below.įor this we will use corkscrew, a tool for tunneling SSH through HTTP proxies available in the official repositories as corkscrew.
