since this is my first post I’d first like to thank everybody for their work, tips and tricks they share. I started using openhab around 2 years ago and up until now I could solve almost all problems I encountered by reading posts and trying to understand (most times failing, but getting better). Since I am a linux novice I hope somebody can help me.
The problem I encounter concerns the command to grant and elevate Java Network Permissions posted in the official installation tutorial
setcap 'cap_net_raw,cap_net_admin=+eip cap_net_bind_service=+ep' $(realpath /usr/bin/java)
First of all I am promted to execute ist as root and the result is always that the openhab service does not start anymore
openhab2.service - openHAB 2 - empowering the smart home
Loaded: loaded (/usr/lib/systemd/system/openhab2.service; enabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Thu 2019-08-22 20:55:25 CEST; 844ms ago
Process: 11359 ExecStart=/usr/share/openhab2/runtime/bin/karaf $OPENHAB_STARTMODE (code=exited, status=127)
Main PID: 11359 (code=exited, status=127)
The solution I found to get openhab to start again is to install Java again.
The reason I “need” to elevate the JAVA rights is that the network binding does not work with arping and my hope is that the elevated rights vor JAVA will fix that.
What am I doing wrong, or is this a bug?
