Hi @lscgzwd -- You're correct in some sense that sysctl is not supported: First, sysctl.conf is not loaded at boot because WSL does not boot (not in the traditional sense at least). Second, many files under /proc have not yet been implemented, so you can't set those things yet. However, some have been implemented (more in recent Insider builds -- it's an ongoing process, more are being implemented over time), and I imagine (though I haven't tested) that you could manage any that have been implemented using sysctl.

Thanks for you answer, I'm already have the latest build.

Please try a more recent Insiders Build and reopen this issue if you still hit these errors

No come on. Repro is cat /proc/sys/net/ipv4/max_dgram_qlen etc. They all need to be stubbed. This blocks all manner of networking things. [ed] That first one is the cause of the warning message in the middle of the screencap here for example.
