Our office LAN is getting painfully slow. It's likely that something is hogging the bandwidth.
If I were to put a network hub between the ADSL router and the main office switch, presumably I could run something on a PC also connected to that switch which would point me in the direction of the problem?
I'm looking for something fairly simple, that would tell me (eg) which IP address was generating most of the traffic, and perhaps on which ports. Wireshark would probably do what I need but it's not (from what I remember) particularly simple to get simple results from.
Or, is there a better option?
Throw a linux box with two NICs in between the ADSL router and the office switch, set the two nics to bridge, and get the bridge to get an IP - that way you can talk to the linux box remotely... Now, use ntop or iptraf (actually, iptraf would probably do what you want nicely) on the bridge device and bob's your mother's brother.
