Why did LibreElec send 2 HUNDRED THOUSAND DNS requests for ipv4.connman.net

  • My connection had a hickup last night and in that time for some reason LibreElec decided to send 200000 dns requests. I wouldn't have noticed if i didn't send it through Pi-Hole on another Pi.

  • Librelec uses ConnMann network manager, which is designed for use with embedded devices. It's provided by Intel and is safe to operate.

    The archlinux wiki has more details in case you're interested:

    ConnMan - ArchWiki

    But since this is LibreElec, some of the details doesn't apply here.

    Connman checks it is online as part of startup. It is harmless and there is a public declaraction that access to ipv4/6.connman.net is not logged. It can be disabled if needed. Copy /etc/connman/main.conf to /storage/.config/connman_main.conf and edit "EnableOnlineCheck=true" to false, save the file and reboot. The reason it's logged so many connection attempts is you're probably blocking it and thus it retries multiple times before giving up. If you allow it to succeed it doesn't need to retry.
