Thanks, @crashtua for the post and @therealkenc for the diagnosis. Yes, currently, WSL does not has support for AF_PACKET address family. If you can open a user voice ticket for this, it will help us prioritize it.

This feature would be great if implemented ! https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/17817685-support-af-packet-address-family-tcpdump-wireshar

@gpotter2 - Thanks for opening the user voice ticket. Just FYI that SOCK_RAW is currently supported for RAW, UDP and ICMP(V6) protocols. TCP can follow without much problem. So, I would restrict the user voice ticket for AF_PACKET and also add what applications are dependent on it. Now, let's get some votes behind it.

@sunilmut Edited :)

Why ppl like Linux because Linux has fewer restrictions, people can do more what they want to do.
Please don't bring the limit from windows to the WSL.if only can do the windows can do,why we should be use WSL?

Soo,when could be the problem soloved?
