I've had LS for a wee while and cannot claim to be a proficient user. A while back I was losing lots of my precious monthly data and with the help of LS identified the drain as nsurlsessiond which I have put a bar on and all is well.
I tend to leave the computer on for days at a time and after a while I notice that Firefox (for instance) has made connections with several hundred servers. I'm sure most of these are benign but how do I identify stuff that is not? Is there a library out there of servers to look out for? I like being able to watch the Network Monitor and see the traffic. LS4 has maps of the world I see. Is this available on LS3.7.4 and I just have not found it yet?
