There was a recent thread about checking traffic volumes and the recommendation was for NetMeter. I ran this just to see and it provides lots of information about total traffic and will produce logs. Does anyone know if there is a tool out there which will tell you what program is using the connection to the ISP? It is easy enough to see, for example, if your AV is running an update but what about other programs that grab the link and make use of it? Any ideas anyone?
