| In: |

| Parent: | Object |
An implementation of a SOCKS4 proxy. To use it, instantiate it, then pass the instantiated object via the :proxy key to Net::SSH.start:
require 'net/ssh/proxy/socks4'
proxy = Net::SSH::Proxy::SOCKS4.new('proxy.host', proxy_port, :user => 'user')
Net::SSH.start('host', 'user', :proxy => proxy) do |ssh|
...
end
| VERSION | = | 4 | The SOCKS protocol version used by this class | |
| CONNECT | = | 1 | The packet type for connection requests | |
| GRANTED | = | 90 | The status code for a successful connection | |
