Freeware program Who’s Connected analyzes and displays your active Internet connections. It’s a quick and simple tool for finding out what programs are using your bandwidth.
Who’s Connected may come in handy when you suspect a bandwidth hog on your computer, but can’t seem to find the culprit. While the software currently lacks a bandwidth monitor for each connection, the feature is currently in development.
I’m one of those guys who has to make things difficult computer-wise, running all sorts of strange application combinations that the designers never imagined someone would do. The other day I ran a netstat and determined that there were hundreds of connections going every which way and I had no idea where they were coming from. LifeHacker just happened to post this little tool which will tell you which app is opening all those connections. In my case it was Cloudmark SafetyBar, an anti-phishing toolbar, which I’m sure is an ok product, but something in my configuration, probably my winsock proxy client, causing it to spread tentacles wildly all over my tcp/ip stack.
