mininet-wifi container with python3 #330

Closed nomanmazhar closed 2 years ago

nomanmazhar commented 3 years ago

Hi,

1:- I am using containernet from "https://github.com/containernet/containernet"

2:- But for wifi i install containernet from "https://github.com/ramonfontes/containernet.git"

the topology made in first containernet does not work in the second containernet.

Both uses different version of python.

please guide me how can i run topology made in python3 to run in wifi based container.

thanks

regards noman

Did you compile the code with the same Python version (sudo make install)?

nomanmazhar commented 3 years ago

Yes i have compiled using python3 Also i am using UBUNTU 20.04LTS the wifi container net successfully install but when i compile my topology it gave following error

example topology

this example topology produce same error

nomanmazhar commented 3 years ago

i have compile the containernet using "sudo make install"

please let me know how to compile the code .....

what command i need to use

nomanmazhar commented 3 years ago

Also the containernet-wifi is running perfectly fine

only getting erro in containernet_example.py

ramonfontes commented 3 years ago

I didn't check the other sample files. I can only confirm the wifi example.

In Containernet_wifi if i try to add link it gave error
