WSL2 Virtual can interface error : recv failed with error: 11, remove this node 4
I refered these 2 blogs to enable vcan in WSL2: https://www.reddit.com/r/CarHacking/comments/ot3gjf/socketcancanutils_on_windows/
My environment
OS : Windows 11 Kernel : 5.10.102.1-microsoft-standard-WSL2
Well worked file following the blog copied onto my directory
# .wslconfig
[wsl2]
kernel=C:\\Users\\an\\vmlinux
At the first, my program well executed.
After once I rebooted the laptop, below error is shown and can't run my program with errors.

I assume that somewhere my socket is running on after reboot.
I would like to find/stop the socket working behind. How can I check and stop?
Solution
I solved the problem I was caused by configuration.
So, I rebuild my kernel for vcan as below.
sudo apt-get update -y
sudo apt-get install -y autoconf bison build-essential flex libelf-dev libncurses-dev libssl-dev libtool libudev-dev make
sudo apt-get install -y bc
sudo apt install -y dwarves
