Cannot access ethernet camera from within docker container

[theateist]

Describe what you want to implement and what the issue & the steps to reproduce it are:

I'm trying to connect to the camera from a docker container.

OS: Ubuntu 22.04.4 LTS Pylon: pylon_7.5.0.15658-deb0_amd64

The camera is connected to ethernet interface enp0s31f6 which is on static ip 192.168.2.10/255.255.255.0. The camera is on static ip 192.168.2.11/255.255.255.0

I built pylon-ros-camera and it successfully detected the camera on the host

But even though I successfully built the same package inside a docker container, it cannot detect the camera

What I tried

• To allow the container to see the interfaces on the host, I run the container with networking as docker run --network=host -d myimage .... And now if I run ifconfig inside the container, it shows me the same interfaces as on the host. See below ifconfig output on host and inside container. But, it still cannot detect the camera.
• I ran the container with extended privileges as docker run --network=host --privileged -v /dev:/dev -d .... But, it still cannot detect the camera.

What might be the problem?

Is your camera operational with the Basler pylon Viewer on your platform?

Yes

[SMA2016a]

Sending the ping from docker to 192.168.2.10 works fine? Sending the ping from docker to camera works fine?

if not will you create a tcp dump in the docker while starting your application in the docker
