[chef] reg winrm auth

[indra < >]

Hi,

         Using winrm itself,how to authenticate windows from linux 
using ruby?

here is my code:
   winrm     = WinRM::WinRMWebService.new("172.16.1.197", :plaintext, 
:user => "administrator", :pass => "
 ", :basic_auth_only => true)do
 puts "connected successfully"
end

BUt it doesnot shows connect successfully ,it doesnot execute do loop 
,also not showing any error

Thanks,
Indra
