Hi,

I'm trying to build the app human-pose with the command: oakctl app build .

I get this error:

    Hmm, seems like you don't have internet access.

          Hi jakaskerl ,

          I don't think that this is the problem, as from the device I'm able to ping external websites, as such google.com.

              AlessandroB
              From the device, yes. But looks like the issue is access from within the container. Which OS version do you have on the OAK4 and which oakctl version? cc @Ales

              Thanks,
              Jaka

                @jakaskerl,

                Here you are the screenshot containing the information that you requested. I don't know how to ping from within the docker.

                Thanks,

                Alessandro

                Hi @jakaskerl ,

                I get the same error also after updating to 1.14.1.

                Just as a note: the OAK device is connected to my PC that shares with the camera its wireless internet connection. As I've already said, from the device terminal I can ping external websites, deb.debian.org included.

                Thanks

                18 days later

                Hey @AlessandroB ,
                What's the output of this command for you:
                ssh root@192.168.10.15 "ping deb.debian.org"

                I would just like to double check that your camera has a connection to the internet.
                Thanks!
                Filip

                  Hi filipjeretina ,

                  Please find in attachment the result of the ping command.

                  I share with OAK the internet connection of my laptop.

                  I modified /etc/resolv.conf (please find the file screenshot in attachment). I have to modify it any time I power up the system, I guess that it is part of the filesystem image.

                  Thanks!

                  Alessandro

                    Hey @AlessandroB
                    Okay, that explains it more. I think your networking setup should work if you copy your custom /etc/resolv.conf into the container, could you try that?
                    Thanks

                      Hi filipjeretina ,

                      I'm running oakctl on my host pc. How can I copy the file into the container?

                      Thanks!

                      Alessandro

                        Hey @AlessandroB ,
                        You can edit the oakapp.toml file to copy the resolv.conf to /etc/resolv.conf in the container.

                        Here is the line to add to oakapp.toml under the prepare_container section:

                            { type = "COPY", source = "path-to-local-resolv.conf", target = "/etc/resolv.conf" },

                        path-to-local-resolv.conf is the path to the local copy of the /etc/resolv.conf from the device.

                        Thanks,
                        Filip

                        Hi filipjeretina ,

                        I'm now able to connect, but I'm getting a different error:

                        Second question: in the toml file do I have to use the paths of the host PC of the device filesystem?

                        Cheers

                        Alessandro

                          Hey @AlessandroB ,
                          I think the issue is the same as before, but now in the build container. You can edit the prepare_build_container steps in the oakapp.toml file to include the same line as you added to prepare_container:

                              { type = "COPY", source = "path-to-local-resolv.conf", target = "/etc/resolv.conf" },

                          Second question: in the toml file do I have to use the paths of the host PC of the device filesystem?

                          That depends on the context of the command. For RUN commands for example, you will always use paths of the device file system (inside container). When using a COPY command the source is the path on the host system, and the target is the path of the device fs (inside container)

                          All the best,
                          Filip

                          Hi @filipjeretina ,

                          I modified the toml file as you suggested, but I keep on getting this error:

                            1. Does docker work as expected: if you create a container and try to access the network from there, does that work or do you run into a similar issue. Make sure you run the container in host mode, not bridge.

                            2. Can you explain your network topology. We'd like to reproduce the issue on our side so we can find the issue.

                            Thanks,

                              Hi @jakaskerl ,

                              My laptop is connected to a company network in wireless, then I connect the OAK to the laptop P2P (I actually use a switch just for PoE).

                              When I power the OAK up I need to update the date and the time, otherwise I can't download data because of time mismatch. Then I need to update the /etc/resolv,conf file to use the google DNS (as shown previously in this thread).

                              I took your human_pose application and updated the toml file by addding in prepare_container: { type = "COPY", source = "/data/resolv.conf", target = "/etc/resolv.conf" }. I had to copy the resolv.conf file in the device /data folder, otherwise the device doesn't connect to the internet (I'm a bit surprised as I thought it would work even copying from /app/resolv.conf as I put this file in the application folder too, but it doesn't work).

                              Then I launch oakctl app run . . The building correctly starts and I see that it correctly run the apt-get update and install commands in prepare_container. Build and application layers are processed too, but when it comes to process the layer app, I get:    [2025-07-22T08:29:28Z] WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip.vendor.urllib3.connection.HTTPSConnection object at 0x7f804f8f50>: Failed to establish a new connection: [Errno -3] Temporary failure in name resol

                              The laptop P2P wired connection is set up so that the internet connection is shared. In fact, the device can access the internet.
