Network Probing Software

Hi,

I think a device on my network might be saturating alot of my network bandwith.

Is there any free monitoring software I can run on a workstation that will probe the network and tell me whats hogging the network?

Such a simple question seems like it should deserver a simple answer: Wireshark. It's free. But you need to have an understanding about switches, ports, mirroring, hubs . . . Years ago, it was simple to do what you want to do: plug into a hub and you'd see all the data passing throught that hub. If you have a switch that allows you to mirror ports you can see all the data going through the switch provided your switch is beefy enough to replicate all the data to a single port without causing problems.

What's your architecture? Layout? Complicated? Simple?

Good luck,

Setup is simple, standard windows with normal switches.
What kind of switches? Do they have port mirroring capability?

SteveJ
No port mirroring
Well, can you get your hands on a hub?
Sorry, yes, we have one managed switch a Linksys SRW-2024 and 3 other linksys switches that are not managed.
The SRW-2024 does do port mirroring.

What do I need to do?

All non managed switches are patched into the managed switch.

I think I can manage to do that.

How would you scan the LAN network to see if something was sending out too much traffic?
