how to know link for ongoing download in the system?

[karimkhan]

When I start internet using USB dongle, it show upload and download going on though I have not started it. It might be that automatic update would be there in any of the application and it would be going on.
Using netstat command I tried to know that on which link or ip download is being going on but it's not showing it,
Is there any other way to identify that where and what upload or download is going on?
In task manager also it's not showing any application running..

You can use something like netshark that will capture packet data.

yeah tools are there like wireshark also, but everytime i need to open is not feasible for me, I just want to do using some command without using any software...

Well the netstat command you mentioned in your first post shows open TCP connections. But that's only if the connection is still open when you run it. If it opens, sends data, then closes, you're unlikely to run the command at the same time it's sending. That's why you should use a packet capture program.
