At the moment I have an application/service/widget/plugin/cronjob whatever, accessing the internet on a regular basis. I could go into the details of my specific issue but I'd rather have an answer that will allow me to fault find it my self and in the process learn more about Ubuntu.
I'm using dnstop
at the moment to display all of the DNS requests that are being made on my network. Currently for arguments sake, there is a request going to weather.noaa.gov
on a 15 minute cycle. It's probably a weather widgit although I have checked my processes and found nothing, and the request is comming from my computer.
So the question, how do I determine what process is accessing weather.noaa.gov
?
I don't want to go through a process of ellimination by shutting down each service/plugin/application to figure this out. I would like to find a way to determine what process is making that DNS request.
If I had a decent "Application Firewall" the request would have never been made. But this is a "horse has already bolted" scenario and would like to find that "rogue" process that is making that DNS request.
