[WingPig99]

What version of Go are you using (go version)?

Does this issue reproduce with the latest release?

No, haven't try.

What did you do?

Try to listen raw IP packet using net.ListenIP("ip:50", address), see https://play.golang.org/p/iW558sJvrWq

What did you expect to see?

Run succeed.

What did you see instead?

socket: operation not supported on socket

do you have the appropriate permissions? try running as root

[WingPig99]

Thanks, Sean. I tried with root permission, still has the problem on macOS. It works on Ubuntu 20.04.3.

sudo go run test.go
2021/11/16 15:34:01 Listen IP failed listen ip:50 127.0.0.1: socket: operation not supported on socket

[seankhliao]

I think this is due to darwin-xnu only allowing the kernel to handle IPSec, though it's difficult to find documentation for this

[WingPig99]

@seankhliao Thank your for your reply. Should I close this comment or let it to wait further information?

[seankhliao]

Given that there's nothing Go can do about this I think it can be closed
