Assets dont display if RasPi unable to access internet

Anthias
1

Hi all. We have installed Anthias onto Raspberry Bullseye and connected to the internet it works fine.
Now we have to run it on our internal company network that does not have internet access, except via proxy. The system boots but hangs eventually giving some access error messages.
Is there a way to disable the need to access the internet ?
Failing that, is there a way to make it work through a proxy ?

Thanks
Hardy

@hardy, will you be able to provide the error messages?
You can configure the proxy settings similar to how you configure the proxy settings on a Linux machine.
I haven’t looked at it closely, but here are some reference/s that could keep you going:

ok. I have tried to config the proxy using raspi-config, and then in the /etc/environment file
The env file at least allows wget to work through the proxy. But our console screen is still blank.
Following also tips from here: Can’t Get Screenly to Start - Anthias - Anthias Forum I can see some logs using journalctl.

A very quick look into docker (that I also no knowthing about), docker ps command lists nothing.
Dont know if this is any help, but I’m looking forward to some advice.

Thank you

So, I also tried the rebuild on the above mentioned post. (./screenly/bin/upgrade_containers.sh)
This fails with DNS lookups - expected with a proxy setup. So something on the docker is not observing the proxy config.

~ $ ./screenly/bin/upgrade_containers.sh
WARN[0000] /home/hvn/screenly/docker-compose.yml: version is obsolete

(and many more like this - but I can’t paste cos I’m limited to posting 2 links)

If you’re having trouble with Docker not acknowledging the proxy settings, this documentation might help: Configure Docker to use a proxy server | Docker Docs.

ok, thank you. I did find that and am working on this one.
Would be much nicer though to switch it off. I mean why once we have a running system do we need to have internet access at all ?
Can this update check or whatever it is be disabled ?

7

ok. So we got this working. A few things required.

  • Setup the proxy with authentication using raspi-config in the advanced settings. Set all proxies to http://userid:passwd@proxyip:port
    Also setup NTP to use an internal NTP server. (update the timesyncd.conf file)
    Then we run the screenly base install with
    bash <(curl -sL https://install-ose.srly.io)
    This should get docker installed but it wont finish due to proxy.
    So after a reboot, setup the docker proxy settings using your link above (adding the same setting for proxy as above)
    Then we can get docker to install/update the screenly with
    ./screenly/bin/upgrade_containers.sh
    A final reboot should see it working.
    Hope that helps someone else.
    Thanks for your help nicomiguelino

Sorry to dig up an old thread but I have a similar issue/request: I need to run Anthias on a network without an internet connection.

I am able to connect to the UI, I’m able to upload new assets but it will not display them.

Note: If I connect the Pi to a network WITH internet connectivity, bingo the assets start working. Furthermore, If I move back to the network without internet, those assets continue working but any new assets fail until I repeat the above.

@TheJMan, without an Internet connection, displaying image and video assets should work fine. Web assets, on the other hand, won’t be displayed.

I’d like to get the following information:

  • Docker logs of server and viewer services; Details on how to get those logs can be found here.
  • Raspberry Pi hardware version
  • Anthias version (for example., master@06d8967)

Thanks!

Thank you so much for responding @nicomiguelino!

In order to get some nice clean logs I decided to rebuild the PI from scratch and wouldn’t you know it, the problem isn’t happening anymore.

Having said that I will continue to monitor over the next couple of days and upload a bunch of different types of content etc. Will come back if I can re-produce the error.

Thanks again.

Good news (or bad news I guess) - I have been able to re-produce this issue. It wasn’t till 24 hours after I rebuilt (and several reboots) that I started to see the issue again.

I am using a Raspberry Pi 3 Model B Rev 1.2 and am on master@8d74226.
I will gather the requested logs. Standby

More good news, I have identified the issue - It appears to be with the timestamp of the uploaded asset. If I upload an image and leave it as manual it doesn’t display. In order to get the image to display I need to change the start date back at least 2 days…
