Problem with the fale switch project

[ANN92610]

I download this project and try to run it. However, when I tried to run it, it shows following message:

@ubuntu:~/Fake-Switch-Project-master$ sudo python MichaelFakeSwitch.py
Traceback (most recent call last):
File "MichaelFakeSwitch.py", line 221, in
s.connect((host,port))
File "/usr/lib/python2.7/socket.py", line 228, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused

Why is that happening?

thanks
