I just need to get how much bandwidth is used in 3 or 4 days. Do you have any application in the terminal to do it?
I'd prefer if it didn't use SNMP.
I found iptraf, wireshark, cacti, but they were not what I am looking for.
Of course I need to save my results; for a single computer, not a network.
It's very important that I can see the total size of inbound and outboud traffic. What solutions are there for me?
