WSL-WatchDog

monitor wsl: start or restart wsl automatically, update or create firewall rules & proxy, create scheduled task...

Why ?

the latest version of wsl stops if you are not connected to the console, or if there is not a job / process a foreground (it can be just a loop in a shell for example)

My need :

• have a linux wsl running in the background
• that wsl can be launched when windows is launched
• a scheduled task check every xx minutes that wsl run
• create / recreate the firewall rules
• create / recreate portproxy v4tov4 rules
• change the @IP address of the vEthernet card (WSL) and disable the @IP V6 if necessary
• store wsl, scheduled task, firewell rules, etc settings in yaml file

What should you do in the linux distribution ?

Create a start.sh file, you can change the name (see in the yaml file in WSLCommon/StartWSL), in which you will have to launch a process or create an infinite loop for WSL to remain active.

What wsl_watchdog.ps1 does ?

• An elevation of privilege (admin) if necessary like "run as administrator" reads wsl_params.yml
• load wsl_params.yml
• check if the wsl distribution is active (see Distro in wsl_params.yml)
• check Firewall rules (see Ports in wsl_params.yml)
• check Forwardings rules (see ProxyV4 in wsl_params.yml)

What do you need to ro create wsl_watchdog sheduled task : ?

Install Powershell-Yaml

• In PowerShell as Administrator

  Install-Module powershell-yaml

Edit wsl_params.yml for the WSL distro to use and the location of WSL-Watchdog scripts. wsl --list shows installed distros.

Call wsl_create_task.ps1. This script read thle yaml file wsl_params.yml, create wsl_watchdog task with 2 triggers :

• atstartup : to start wsl_watchdog.ps1 script
• daily : start wsl_watchdog.ps1 script evry 5mn (see TaskDuration in wsl_params.yml)
