Hi,

I think that execution command is wrong.
Please try the following.
sudo ./customNet.py
Note:
The following files are describes how to use the "--custom ***.py".
mininet/custom/README
mininet/custom/topo-2sw-2host.py (Custom topology example)
In addition, python script need to be modified as follows.
(UserSwitch: a switch using the user-space switch from the OpenFlow)

- s1 = net.addSwitch( 's1' )
- s2 = net.addSwitch( 's2' )
