First start the server
python3 src/start_server.py -v -H 127.0.0.1 -p 2000 -P {saw, gbn} --storage src/server/files/
Open a new terminal and upload a file
python3 src/upload.py -v -H 127.0.0.1 -p 2000 -P {saw, gbn} --src src/donald.jpeg --name donald.jpeg
Open a new terminal and download a file
python3 src/download.py -v -H 127.0.0.1 -p 2000 -P {saw, gbn} --dst src/client/files/ --name donald.jpeg
We use comcast to simulate packet loss. device parameter should be the name of the network interface (e.g. eth0) and it can be found with wireshark
comcast -device=lo --packet-loss=10% -target-addr=127.0.0.1
To stop the packet loss. device parameter must be the same as before
comcast -device=lo --stop
Creating virtual environment
python3 -m venv venv
Activating virtual environment
source venv/bin/activate
You can confirm you’re in the virtual environment by checking the location of your Python interpreter:
which python
As long as your virtual environment is activated pip will install packages into that specific environment, and you’ll be able
to import and use packages in your Python application.
Installing dependencies from requirements.txt
python3 -m pip install -r requirements.txt
