Title: Real time display of bandwidth thieves?
Post by: Dan on October 14, 2003, 07:47:13 PM

I use 5.6U5 on several machines in small wireless ISP. I have QoS set up on all of them to load balance the bandwidth usage of my clients but sometimes I notice that things slow down a little - it's only after the SARG cron job running at midnight that I can find out who was doing the huge downloads.

Is there any way I can see in realtime where the bandwidth is going? I suppose a manual command to run SARG via SSH would suffice if there was no other elegant solution?

Perhaps:

The "Sample Subnet Summary with -d 2 option" looks like something that may be very useful to you.  It's pcap based too, which means it should work fine with 5.6 after you install pcap.

Also, may want to check out ntop as well.

Also there is netprobe, I find netprobe easier to use than ntop, but that's just my personal opinion.

There's a howto here:
