Check this for a detailed explanation

Or what is the correct rule for this?
$ sudo setcap cap_net_raw = + eip path_to_domoticz_executable

example (my domoticz binary is in /opt/domoticz directory)

sudo setcap -v cap_net_raw+eip /opt/domoticz/domoticz    # returns >>  /opt/domoticz/domoticz: OK
sudo getcap /opt/domoticz/domoticz  #returns >> /opt/domoticz/domoticz = cap_net_raw+eip

Hallo Waaren,

Thanks for this super quick response.

Unfortunately, this information is too much for my limited knowledge.
The question is therefore do I need this for internal use?
I ran a test and it works.

I also looked at the paths on the SD card but can find /opt/ but not /opt/domoticz

Best regards, cobra045

It is an explanation for why a non root user should get additional capabilities for certain tasks and an overview of what these capabilities are

If it works and you are OK with not knowing why it works, I am not the person to tell you if you need to understand it or not. There are probably very few people in he world understanding everything there is to know of a system like Linux

I also looked at the paths on the SD card but can find /opt/ but not /opt/domoticz

See my remark that my domoticz binary is in /opt/domoticz. Youre domoticz binary will most likely in another directory. Most users on a raspberry have installed it in the directory /home/pi/domoticz, but you can install it in any directory.

after running setcap, you need to restart your domoticz service. It took me a while to get it to work, and all I should do was to restart.

@waaren, I'm stille looking into the problem I have with the script.I have create a complete test enviroment, so I think is should be possible for me to finde the cause to the problem. I'm going for a week - so until next weekend ....
