NAME

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

SYNOPSIS

-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 HTTPPROXYPORT 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.
