PQCLass report from my side

MacOS

• Problem :
  • The collector.py wasn't create any data, so,I provide just the temporal files.
  • The MacOS desktop wasn't mine, so I couldn't spend more than two days troubleshooting.

Linux- Ubuntu

• Problem : Debian

  • ydotool and pkt2Flow wasn't working on Debian
  • So, I use the Ubuntu and then was okay

• Problem : python version

• Problem -> Python

  • Error whenrun the ./runner.sh
  • This was due to Inconsistencies in the python libraries with Python 3.8 (default and preferred python for Ubuntu 20.4 that i use ),

    [ERROR viaduct::backend::ffi] Missing HTTP status
    [ERROR viaduct::backend::ffi] Missing HTTP status
    Traceback (most recent call last):
    File "./collector.py", line 9, in <module>
    def loop_thru_all_files_in(path: str, ips: list[str]) -> tuple[int, str] | None:
    TypeError: 'type' object is not subscriptable

  • Solution
    • Change to python 3.10 in venv
    • So I create a venv with python 3.10,then I download the requirements, and then IN the runner.sh before call the collector.py I activate the venv e.g. source venv/bin/activate

• Problem : pkt2flow

  • Solution

  • nano pkt2flow.c & nano utilities.c -> Add this line at the top ->

    • #define _GNU_SOURCE -> save& and recompile with -> scons

  • Problem : ydotoold

    • Correct installation

    sudo apt update
    sudo apt install cmake make g++ libevdev-dev libudev-dev
    git clone --recursive https://github.com/ReimuNotMoe/ydotool.git
    cd ydotool
    mkdir build
    cd build
    cmake ..
    make -j$(nproc)
    sudo make install
    sudo systemctl enable --now ydotoold
    ydotool key 30:1 30:0  # Simulates pressing 'a' , 
    #SOS  if ydotool fail, then  do the next line 
    sudo systemctl restart systemd-logind
    sudo /usr/local/bin/ydotoold &   # Try running the daemon directly:
    ydotool key 30:1 30:0  # Simulates pressing 'a' , 
    # If it still needs sudo, try:
    sudo chmod 777 /tmp/.ydotool_socket
    

    # SOS Make ydotool , Persistent After Reboot
    sudo nano /etc/systemd/system/ydotoold.service
    # And add:
    [Unit]
    Description=ydotoold Daemon
    After=multi-user.target
    
    [Service]
    ExecStart=/usr/local/bin/ydotoold
    Restart=always
    User=pash
    
    [Install]
    WantedBy=default.target
    
    # Then 
    sudo systemctl daemon-reload
    sudo systemctl enable --now ydotoold

Windows

I modify the runner.ahk in order to :

• comment/uncomment each line based on the scenario I want to run
  • StartIndex
  • corresponding selection of Path address for the firefox & chrome .exe
  • --browser & --pqc corresponding selection
• SplitCap using correct file index

#Requires AutoHotkey v2.0
