Pcap4J integrated?

[andy-ich]

Hi, Amazon Dash Button Binding doesn't work.
Has Pcap4J been integrated?
http://docs.openhab.org/addons/bindings/amazondashbutton/readme.html

I´m using openhab/openhab:amd64-online on:
Synology DSN 6.0.2-8451 Update 7
Docker App V. 1.11.2-0268

Otherwise it runs well up to the following Bug:
#12

Thanks for your great work!

Can you try it? The PR #43 close the Issue #12

For Amazon Dash Button, dersimon suggests in his comment (on https://hub.docker.com/r/openhab/openhab/) this update:

To get pcap working, create Dockerfile with these contents:

FROM openhab/openhab:amd64-online
RUN apt-get -y update && apt-get install -y libpcap-dev
CMD setcap cap_net_raw,cap_net_admin=eip `realpath /usr/bin/java`

ENTRYPOINT ["/entrypoint.sh"]
CMD ["server"]

However, starting the Container with --net=host currently won't work with Docker for Mac according to this issue.

openhab/openhab:amd64-online is not actual!
openhab/openhab:amd64 is actual!

@nokyyz: I have tried hours to get libpcap working in the docker container without success. If i add following lines to the dockerfile they do not work as expected. If i run the command in the docker container they work, but when i restart the container it does not start anymore and the changes seems to be gone. I have tried privileged mode as well. I have read a lot of problems with aufs and x_attr support, but i have no solution yet. If i run the container as root it works.

setcap cap_net_raw,cap_net_admin=eip /usr/lib/java-8/bin/java
setcap cap_net_raw,cap_net_admin=eip /usr/lib/java-8/jre/bin/java
patchelf --set-rpath /usr/lib/java-8/lib/amd64/jli /usr/lib/jvm/java-8-oracle/bin/java
patchelf --set-rpath /usr/lib/java-8/jre/lib/amd64/jli /usr/lib/jvm/java-8-oracle/jre/bin/java

Pleas help me to find a solution :-) I need this feature as well.

@andy-ich: With my last PR #69 i got the amazondashbutton plugin working running the image as root with the following command:

docker run -u root -it --rm --cap-add NET_ADMIN --cap-add NET_RAW --net=host openhab

Feel free to modify the run command after this PR is merged and let me know if it works as expected.

@legacycode : I have upgraded today my OH2 docker image to check your solution.
During the discover, my Amazon Dash Button is well found. But, I don't receive any events when I press the button.
Here my conf:

openhab2:
  container_name: openhab2
  image: 'openhab/openhab:2.0.0-amd64'
  restart: always
  ports:
     - "8080:8080"
     - "8443:8443"
     - "5555:5555"
  net: "host"
  cap_add:
    - NET_ADMIN
    - NET_RAW
  volumes:
    - '/etc/localtime:/etc/localtime:ro'
    - '/etc/TZ:/etc/timezone:ro'
    - '/volume1/docker/openhab2/userdata:/openhab/userdata'
    - '/volume1/docker/openhab2/conf:/openhab/conf'
    - '/volume1/docker/openhab2/addons:/openhab/addons'
  devices:
    - "/dev/ttyACM0:/dev/ttyACM0"
  environment:
     - "EXTRA_JAVA_OPTS=-Duser.timezone=Europe/Paris -Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0"
  user: root

rule:

rule "Dash button pressed"
when
    Channel "amazondashbutton:dashbutton:xx-xx-xx-xx-xx-xx:press" triggered
then
    sendTelegram("xx", "Hello world !")
end

Is it necessary to execute setcap command after the Docker run command ?
Did you succeed to trigger a rule on press event ?

I've tried everything in this thread and can't even get the buttons to show up in the Inbox after searching. I've used the docker-compose.yml file and run as root. I get nothing. I'm trying to run the armhf version on an Odroid-XU3.
