Hi All,

I am installing mini-ndn on a VM with ubuntu 18.04 following all the instructions on the wiki. But i am seeing below error after installing and executing mini-ndn examples:

sudo python examples/nlsr/pingall.py Traceback (most recent call last): File "examples/nlsr/pingall.py", line 26, in from mininet.log import setLogLevel ImportError: No module named mininet.log

Can you please let me know if I am missing any configurations or steps.

Thanks, Sachin

Probably mininet is not installed in your system. Can you please verify that? you can try sudo mn or run any of the examples inside mininet/examples directory.

I have installed and pingall worked fine.

/home/ndn/mininet ndn@ndn:~/mininet$ sudo mn Creating network Adding controller Adding hosts: h1 h2 Adding switches: s1 Adding links: (h1, s1) (h2, s1) Configuring hosts h1 h2 Starting controller c0 Starting 1 switches s1 ... *** Starting CLI: mininet>

Can you check if your default python is python2 or python3? If it's python2, try executing the examples using python3 -- sudo python3 examples/mnndn.py. I had this problem earlier.

I tried both versions, still same issue. How can i uninstall and re/install again?

Also is it possible to run ndn-traffic-generator tools on mini-ndn nodes to generate bulk traffic?
