sudo and libpcap error

[ashwin]

I tried to run this on WSL on an x86 machine and got this error:

$ sudo ./dnspeep
Error: Failed to start. You need to run this as root.

Caused by:
    libpcap error: socket: Address family not supported by protocol

Location:
    src/main.rs:91:10

I am not sure why it says You need to run this as root. when I am running it as sudo. And there is also the libpcap error, which I am hoping is because of the sudo error.

This isn't because of sudo, that's a red herring -- I updated the error message to say "you might need to run as root" instead of "you need to run as root". I think this might be a WSL issue.

Are you using WSL1 or WSL2? I found this issue which looks like it's saying that libpcap doesn't work at all on WSL1: microsoft/WSL#1349

@jvns I am using WSL1. I guess you can close this issue since libpcap isn't supported on WSL1.
