NAME

corkscrew - Tunnel TCP connections through HTTP proxies

SYNOPSIS

  corkscrew  PROXY PROXYPORT TARGETHOST TARGETPORT [AUTH_FILE]

DESCRIPTION

corkscrew is a simple tool to tunnel TCP connections through an HTTP proxy supporting the CONNECT method. It reads stdin and writes to std- out during the connection, just like netcat. It can be used for instance to connect to an SSH server running on a remote 443 port through a strict HTTPS proxy.

PROXY

The name of the host running the HTTP proxy.

PROXYPORT

The port on which to connect on the proxy.

TARGET

The host to reach through the proxy.

TARGETPORT

The port to connect to on the target host.

AUTH_ FILE

The auth file is made of one single line containing your username and password in the form

    username:password
    

OPTIONS

None.

EXAMPLES

The common usage of corkscrew is to put the following line in ~/.ssh/ssh_config:

        ProxyCommand corkscrew proxy proxyport %h %p [<path to auth_file>]

This will let the ssh connection go through the proxy with the help of corkscrew.

ENVIRONMENT

None.

FILES

None.

SEE ALSO
