NAME

IO::Stream::Proxy::SOCKSv5 - SOCKSv5 proxy plugin for IO::Stream

VERSION

This document describes IO::Stream::Proxy::SOCKSv5 version v2.0.0

SYNOPSIS

    use IO::Stream;
    use IO::Stream::Proxy::SOCKSv5;

    IO::Stream->new({
        ...
        plugin => [
            ...
            proxy   => IO::Stream::Proxy::SOCKSv5->new({
                host    => 'my.proxy.com',
                port    => 3128,
            }),
            ...
        ],
    });

DESCRIPTION

This module is plugin for IO::Stream which allow you to route stream through SOCKSv5 proxy.

You may use several IO::Stream::Proxy::SOCKSv5 plugins for single IO::Stream object, effectively creating proxy chain (first proxy plugin will define last proxy in a chain).

SECURITY

While version 5 of SOCKS protocol support domain name resolving by proxy, it unable to report resolved IP address, which is required by IO::Stream architecture, so resolving happens always on client side. This may result in leaking client's DNS resolver IP address (usually it's client's address or client's ISP address) and detecting the fact of using proxy.

EVENTS

When using this plugin event RESOLVED will never be delivered to user because there may be two hosts to resolve (target host and proxy host) and it isn't clear how to handle this case in right way.

Event CONNECTED will be generated after SOCKS proxy successfully connects to target {host} (and not when socket will connect to SOCKS proxy itself).

INTERFACE

new({ host=>$host, port=>$port })

Connect to proxy $host:$port.

DIAGNOSTICS

{host}+{port} required

You must provide both {host} and {port} to IO::Stream::Proxy::SOCKSv5->new().

{fh} already connected

You have provided {fh} to IO::Stream->new(), but this is not supported by this plugin. Either don't use this plugin or provide {host}+{port} to IO::Stream->new() instead.

LIMITATIONS

Only these authentication methods supported:

 - no authentication

SOCKS "BIND" request doesn't supported.

SOCKS "associate UDP" request doesn't supported.
