Network Binding - problem with discovering windows 10

Hi OpenHab team

I need some help – got stuck

Using: Openhab2, Raspberry pi 3, Raspbian, Oracle java version “1.8.0_121”

Implemented “Network Binding” and it seems to be working fine. I have rules reacting when devices get online.

But noticed that I have trouble with discovering 3 devices, which all run windows 10.

I have no problem with doing a ping from the rasp to the win10 boxes.

Found this link:

So, I have executed this command:

pi@raspbox3:~ $ sudo setcap cap_net_raw=ep /opt/jdk1.8.0_121/bin/java

but afterwards, OH2 will not start:

pi@raspbox3:~ $ sudo service openhab2 status

● openhab2.service - openHAB 2 - empowering the
smart home

Loaded: loaded

Also noticed that I can not run java:

pi@raspbox3:~ $ java -version

java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory

removing the ‘setcap’ fix’es the OH2, so it can run but still issues with win10.

sudo setcap -r /opt/jdk1.8.0_121/bin/java

pi@raspbox3:~ $ java -version

java version “1.8.0_121”

Java™ SE Runtime Environment (build 1.8.0_121-b13)

Java HotSpot™ Client VM (build 25.121-b13, mixed mode)

Tried a variant on setcap but with same result.

sudo setcap cap_net_raw,cap_net_admin=eip realpath /usr/bin/java

pi@raspbox3:~ $ java -version

java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory

So, what should I do ?

No comments ? Has this been answered in some other topic that I have missed ?

Bit more searching… and it is now solved…

Amazon Dash, cannot use due permission issue

My command:
sudo ln -s /opt/jdk1.8.0_121/lib/arm/jli/libjli.so /usr/lib/

;-))

And just to finish it…

if there still a Windows 10 box that doesn’t show, follow this guide to enable ‘reception’ of ping on windows box.

Now Paper UI can discover my win10 systems.
