tcpsocket获得远程主机ip信息

		
@server = TCPServer.open(@host, @port)
	  rescue Exception => e
		@log.fatal("SSH protocol start ... failed. (#{e.to_s})")
		raise "SSHServer start failed."
	  end
	  @log.info("SSH protocol start ... ok\n")

	  @protocol_started = true
	  while @server
		@socket = nil
		begin
		  Timeout::timeout(@timelimit) do
			@socket = @server.accept
      p @socket.class.to_s
      p @socket.peeraddr  #获得远程主机IP地址等信息，返回值为数组
      p @socket.addr #本机ip等信息，返回值为数组
