ssh-http-proxy-connect(1) User Commands ssh-http-proxy-connect(1) 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
