Subject: Re: idiot's guide to druby using ssh tunnels

There's nothing special about druby, you'd just tunnel it like anything
else. 

# -------- Server Code:

require 'drb/drb'

class ServerObj
  def initialize
    @count = 0
  end
  def kick
    @count = @count + 1
    puts "I have been kicked #{@count} times"
    @count
  end
end

DRb.start_service('druby://localhost:666', ServerObj.new)

# -------- Client SSH Command:

ssh -f -L 888:localhost:666 username@servername "while echo .; do sleep
60; done" > /dev/null

# -------- Client Code:

  DRb.start_service

  serverObj = DRbObject.new_with_uri('druby://localhost:888')
  10.times {
    puts "Server has been kicked #{serverObj.kick} times"
  }

I don't believe there is an ssh library for ruby, otherwise you'd be
able to get a pure ruby solution.
