[rcaushi_ftnt]

Description	This article discusses triggering dummy traffic using Windows Subsystem for Linux to analyze how the FortiGate is handling it.
Scope	Use this method to generate unattended traffic of a certain type (TCP/UDP/ICMP), especially in situations when the issue is happening randomly and cannot trigger it on will. of a certain type.
Solution	Windows Linux Subsystem In Windows 10 and 11 and use it to run scrips: Step1. Open PowerShell and run: wsl --list --online<----- To see a list of available distros and run. wsl --install -d <DistroName> <----- To install a distro. Step2. Verify the of the WSL instance: $ip route | grep default $ip a <----- Find the IP associated to the dev wifi0. Note: WSL shares Windows OS IP. Step3. Install all the necessary packages and prepare the scripts: $sudo apt update && upgrade $sudo apt install python3 python3-pip ipython3 Download the scripts and copy them into the WLS home directory: \\wsl$ Or alternatively C:\Users\<user>\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu_<random>\LocalState\rootfs\home\ubuntu_rc Store the files in the home directory : Generating traffic: $HTTPS_Traffic_Generator2.py Note: Attached is a simple Python script that runs for 24 Hrs and  triggers every 5 seconds HTTPS traffic towards predefined 'URLs'  defined on urls = ['https://www.example.com', 'https://www.fortinet.com']  Optional Scripts:  If a script is necessary to show a CLI output enable debugging by changing the parameter  DEBUG = False to DEBUG = True. To test with specific destinations edit the section ROOT_URLS from 'config.py'.
