internet bandwidth usage

[hortonhearsawho]

Hi,

can you tell me if there are any free tools that will be able to give me an overview of what pcs are using the bandwidth of my internet connection and possibly protocols being used for incoming and outgoing sessions on the specific pc? thanks.

Ntop is nice. You can also use something for NetFlow if you have it available.

Neither relate to SNMP. Ntop is basically a sniffer, and NetFlow sends stats from the router to a collector.
