Wireshark · Wireshark-users: [Wireshark-users] Capture hardware

[Laurent Chouinard <laurent@xxxxxx>]

Hi,

I need to capture the network data at one of my customer's location, but 
big laptops with power supplies, hubs, cables and everything else 
required to get a wireshark capture going is kind of a difficult problem 
physically.

So I ask: Is there any hardware product whose sole purpose is to receive 
an ethernet cable and record everything internally? I would leave that 
device for a few days, then collect it, extract the data, and run my 
analysis through Wireshark.

So far the closest thing I found is a hardware data logger that is more 
of an electrical level logger to record actual electrical interferences 
into the signal than the ethernet frames. Me, I just need to record the 
ethernet frames so that I know what my device receives and what it 
transmits.

Thanks,

Laurent
