Find who is using my network – top for network utilization

Ok here is something that I have been looking for something.¬† Now that I have conky installed, so I can see the bandwidth usage on my desktop but was wondering for sometimes, where actually so much is being used. So did some quick search to see if I can get that info and did not have to go too far ūüôā

There is s¬† utility called iftop in the Fedora repo and at the URL. Oh and how to use it, just type sudo iftop or if you have multiple network interface then you can do \”iftop -f <device name>\”. Thats pretty simple and cool.

Name       : iftop
