[nsp] Suggestions on tracking down bandwidth offenders

[Tony Mucker]

I've got a bandwidth problem (who doesn't).  Something has been 
saturating my poor little T1 for 24 hours straight now.  For those of 
you curious, here's what it looks like:

Remove the white space and enjoy.  In the past I've used ethereal dumps 
to figure out who the big talkers were, but frankly it takes too long to 
crunch all the packets.  I've also tried etherApe, but the analysis 
makes my poor little laptop crawl.  Are there any tools out there that 
will speed this up?  Possibly by looking at the firewall logs?

Thanks
Tony
