Raw Socket initializing error

[iDevo]

Hi there! I've installed the homebridge-wol plugin like described in the instructions. I've also added the entry to the config.json like this:

{
    "accessory": "Computer",
    "name": "Boston2",
    "mac": "MY_MAC_ADDRESS",
    "ip": "192.168.178.12",
    "pingInterval": 20, 
    "wakeGraceTime": 60,
    "shutdownGraceTime": 15
},

Unfortunately I'm getting this error, when starting homebridge with: hombridge

All my other plugins are setting up correctly except the wol alias Computer plugin. It seems for me like an issue in the raw-socket module but I just want to make sure I didn't misconfigured anything.

Thanks in advance!

Unfortunately using raw sockets requires root privileges. As far as I can tell you have to options, either you run homebridge as root or you give the user that is running homebridge the CAP_NET_RAW (see $ man 7 capabilities.) I don't personally have experience with the CAP_NET_RAW, I run homebridge as root on a dedicated Pi.

Aaaah good to know I'll check it! Okay maybe I'd just run homebridge as root, I don't think that this would have any disadvantages. But please correct me if there are things I should keep an eye, when running hombridge as root. Thanks a lot @blubber !

[blubber]

Well, running it as root implies trust, the root user can do literally everything on the computer. You are downloading and installing software from the internet, it's up to you to decide whether or not you trust the homebridge and plugin developers.

This is not just homebridge specific by the way, it goes or anything you run as root.

I have the same issue with the homebridge-people-plus plugin on a raspberry pi. I got it to run by copying the config.json file to root/.homebridge and running sudo homebridge. But how do I get this to run from the default /home/pi folder the way it should? How can I give user pi the permission it needs? - thanks

@AAShepAA I think there’s a note about it in the readme about “capabilities”. Please try that solution and come back whether it works or not.

I see nothing here: https://github.com/Glavin001/homebridge-people-plus#readme

@AAShepAA I meant in the readme for this package.

I’m sorry I guess I do not know where to find that readme.  But, thank you for your help anyway :)
