Cannot talk to rtnetlink : Operation not supported

Can anyone help? Is this error coming because I am using windows subsytem for linux?

The issue you're facing with the tc qdisc command in WSL seems to be a compatibility issue. WSL, particularly WSL2, might not fully support certain network operations, including those related to netem and tc qdisc. You might need to use a native Linux environment or a virtual machine that provides full Linux kernel capabilities, as WSL2 might not support all the features needed for netem and tc qdisc operations. Or wait for a PR for this to be done. github.com/microsoft/WSL/issues/6065 – Alkalize

Answer 1

Yes it is because of Windows Subsystem for Linux, it is limited. If you install Oracle Virtual Box, and install an Ubuntu OS like 12.04 in a virtual machine, it will let you do it without complaints ;)
