Traffic to CloudFlare - pacman - 2022-07-05 I am running Openplotter on a Raspberry 4B connected to an onboard router with a SIM card for internet access. Last month I had all the allowable traffic eaten from something on the boat (24 GB of traffic! ). I started to dig into the matter and finally discovered that is the Raspberry to consume that much traffic. I have setup a traffic block rule on the router to avoid another total loss of data allowance and with nethogs checked carefully which connections were eating traffic. I discovered a continuous traffic towards the CloudFlare servers, then created another firewall rule to block the traffic to the /16 network owned by CloudFlare. Lastly I enabled and disabled this last rule to verify and actually when the rule is disabled the consumed data clock runs as hell. Finally my question: what can I do to find the process/configuration/application that generates that traffic and stop it? I am not a linux expert and on OpenPlotter I have installed no additional things besides the standard ones. Since it is a continuous flow, it is also wasting cpu resources and I would like to get rid of it. Any help will be much appreciated Thanks in advance |
