Describe the bug

System:

  • OS: Debian 10
  • Virtualization: KVM
  • Clients: not relevant
  • Browser: not relevant
  • Jellyfin Version: 10.6.4
  • Playback: not relevant
  • Installed Plugins: None
  • Reverse Proxy: Apache
  • Base URL: /
  • Networking: Private LAN, no NAT
  • Storage: local

To Reproduce

  1. Setup a firewall with default outgoing policy DENY (I use firehol)
  2. Install Jellyfin from Debian packages
  3. Login as admin, go to Administration > Dashboard > DLNA, disable all DLNA related functionality
  4. Watch server logs. Every minute the following messages are logged:

Expected behavior

Jellyfin should not send multicast/DLNA-related packets when DLNA is disabled in settings. Currently:

  • multicast packets are sent over the network when no restrictive firewall is in place, possibly to untrusted networks (eg. VPS sharing the same LAN)
  • when a restrictive firewall is in place, log spam

I don't know if those packets are sent for discovery of other DLNA devices, or to announce Jellyfin to other devices. Regardless this traffic should not be sent. Or is there another setting to disable DLNA/UPnP completely?

DLNA can be disabled in 10.7.

Do you mean the checkbox is there in 10.6.4, but has no effect, and that it is fixed in 10.7?

Can you upload a screenshot of your settings?

And have you disabled autodiscovery?

And have you disabled autodiscovery?

No. How? I can't find this setting in the web UI, am not sure how to proceed after rereading https://jellyfin.org/docs/general/administration/configuration.html. Should I modify /etc/jellyfin/network.xml? /etc/jellyfin/system.xml? Pass an environment variable on startup?

Thanks

Setting <AutoDiscovery>false</AutoDiscovery> in /etc/jellyfin/network.xml seems to fix the problem. Thanks
