Subject: inheritance in ruby

Hi, all.

I'm creating an automation framework, and met this inheritance
private/protected problem.
Say I'm having SshCon and LinuxSshCon
class SshCon
  def connect
     cmd()
  end
  def cmd
   end
  def search
     cmd("")
  end
end

class LinuxSshCon < SshCon
  def cmd
    format()
    super()
   end
end

lsc = LinuxSshCon.new
lsc.connect # here it would use the cmd in LinuxSshCon, and cause me
some trouble
lsc.cmd

My problem is this:
When I overwrite a method in sub class, is there a way I can keep the
original class calling its own method?
I tried
def connect
   self.cmd
end
or use private/protected to claim cmd, none of them works

thanks
