Interface card using a lot of bandwith
I have system which is using a lot of bandwidth and this is not a big problem,
but how do you troubleshoot this issue?
How can I find out which connections are made for one interface card,
there are about 5 on this system and I can see how much traffic is going through one interface, but I need to drill down more.
Thx.
