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.

NAME

       ssh-http-proxy-connect - Secure Shell proxy for HTTP

SYNOPSIS

       /usr/lib/ssh/ssh-http-proxy-connect [-h http_proxy_host]
	    [-p http_proxy_port] connect_host connect_port

DESCRIPTION

       A  proxy command for ssh(1) that uses HTTP CONNECT. Typical use is where connections external to a network are only allowed via a proxy web
       server.

OPTIONS

       The following options are supported:

       -h http_proxy_host    Specifies the proxy web server through which to connect. Overrides the HTTPPROXY and http_proxy environment variables
			     if they are set.

       -p http_proxy_port    Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the HTTPPROXY-
			     PORT and http_proxy environment variables if they are set.

OPERANDS

       The following operands are supported:

       http_proxy_host	  The host name or IP address (IPv4 or IPv6) of the proxy.

       http_proxy_port	  The numeric port number to connect to on http_proxy_host.

       connect_host	  The name of the remote host to which the proxy web server is to connect you.

       connect_port	  The numeric port number of the proxy web server to connect you to on http_proxy_host.

EXAMPLES

       The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see  Example  1  and  Example  2).
       Example 3 shows how the proxy command can be specified on the command line when running ssh(1).

       Example 1 Setting the proxy from the environment

       The following example uses ssh-http-proxy-connect in ssh_config(4) when the proxy is set from the environment:

	 Host playtime.foo.com
	     ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect 
		 playtime.foo.com 22

       Example 2 Overriding proxy environment variables

       The following example uses ssh-http-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables:

	 Host playtime.foo.com
	     ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect -h webcache 
		 -p 8080 playtime.foo.com 22

       Example 3 Using the command line

       The following example uses ssh-http-proxy-connect from the ssh(1) command line:

	 example$ ssh -o'ProxyCommand="/usr/lib/ssh/ssh-http-proxy-connect 
	     -h webcache -p 8080 playtime.foo.com 22"' playtime.foo.com

ENVIRONMENT VARIABLES

       HTTPPROXY	Takes the http_proxy_host operand to specify the default proxy host. Overrides http_proxy if both are set.

       HTTPPROXYPORT	Takes the http_proxy_port operand to specify the default proxy port. Ignored if HTTPPROXY is not set.

       http_proxy	URL format for specifying proxy host and port.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       1     An error occurred.
