All set :)

Run the network topology

Inside the root folder of the repository run the bash script to perform a clean and safe start:

./runTopology.sh

Or instead run it manually

Inside the root folder of the repository run the script as sudo:

sudo python3 2gnb_4ue_network.py

Runtime issues

If started manually and getting issues try running the clean script located in the root folder:

./clean.sh

Testing connections

Testnet

To run tests simply type:

sudo python3 TestNet5G.py

Test with Wireshark

Verify if it's correctly installed with all dependencies:

sudo apt-get install wireshark

To run it simply type:

wireshark

Permission issues

To enable non-root user to listen to devices use this command and add user to 'wireshark' group:

sudo dpkg-reconfigure wireshark-common
sudo adduser $USER wireshark
sudo chmod +x /usr/bin/dumpcap

note that if you don't have $USER variable you can find it running:

whoami

in my case output is :
vagrant
