Hello all!

I trying to create XMLRPC service with ActionWebService plugin and  
Rails 2.0.2. I use conventional layered based API.

This is my controller:  
class RpcController \< ApplicationController  
skip\_before\_filter :verify\_authenticity\_token  
web\_service\_dispatching\_mode :layered  
web\_service :user, UserRpcService.new  
end

And service:  
class UserRpcService \< ActionWebService::Base  
web\_service\_api UserRpcAPI  
def auth(login, passwd)  
user = User::find(:first, :conditions =\> {:login =\> login, :passwd  
=\> passwd})  
raise UserAuthException, “Auth failed” unless user.instance\_of?  
(User)  
true  
end  
end

In method UserRpcService.auth i need to know from which remote IP this  
RPC call is come (for logging or restrictions etc.).
