/usr/lib/ssh/ssh-socks5-proxy-connect
    [-h socks5_proxy_host]
    [-p socks5_proxy_port] connect_host connect_port

A proxy command for ssh(1) that uses SOCKS5 (RFC 1928). Typical use is where connections external to a network are only allowed via a socks gateway server.

This proxy command does not provide any of the SOCKS5 authentication mechanisms defined in RFC 1928. Only anonymous connections are possible.

The following options are supported:

-h socks5_proxy_host

Specifies the proxy web server through which to connect. Overrides the SOCKS5_SERVER environment variable.

-p socks5_proxy_port

Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the SOCKS5_PORT environment variable.

The following operands are supported:

socks5_proxy_host

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

socks5_proxy_port

The numeric port number to connect to on socks5_proxy_host.

connect_host

The name of the remote host to which the socks gateway is to connect you.

connect_port

The numeric port number of the socks gateway to connect you to on connect_host.

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-socks5-proxy-connect in ssh_config(4) when the proxy is set from the environment:

Host playtime.foo.com
   ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect \
       playtime.foo.com 22

Example 2 Overriding proxy environment variables

The following example uses ssh-socks5-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables:

Host playtime.foo.com
   ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw \
       -p 1080 playtime.foo.com 22

Example 3 Using the command line

The following example uses ssh-socks5-proxy-connect from the ssh(1) command line:

example$ ssh -o’ProxyCommand=/usr/lib/ssh/ssh-socks5-proxy-connect \
   -h socks-gw -p 1080 playtime.foo.com 22’ playtime.foo.com

SOCKS5_SERVER

Takes socks5_proxy_host operand to specify the default proxy host.

SOCKS5_PORT

Takes socks5_proxy_port operand to specify the default proxy port.

The following exit values are returned:

0

Successful completion.

1

An error occurred.
