SSH-HTTP-PROXY-CONNECT(1)SSH-HTTP-PROXY-CONNECT(1)NAMEssh-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. Over‐
rides the HTTPPROXYPORT and http_proxy environ‐
ment 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). Exam‐
ple 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) com‐
mand 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.
