who is hogging bandwidth?

[burnside]

hi,

on my vpn which is a BT metrovpn product involving 256k SDSL lines, i am experiencing slowdown in the comms between a remote site and our core site.
the lines and the kit have been checked ok - so a user/pc at the site must be using all the bandwidth downloading big files.

our db system and internet run over this system.
when things are good a user can download a file at 30 kb/s, when this problem is happening this rate can drop to 10 kb/s. there is no reason anyone should be downloading big files and depsite trying to ask people who is doing it no one is putting there hands up!

i have no experience of sniffers and the like and need some advice on finding out who is using all the bandwidth
and would like some sort of graphical display by ip address of bandwidth usage.

is there an inexpensive system that would give me this detail?

many thanks

What kind of device do you have at both ends of your VPN network?

hi zen37

at the remote end is a cisco 837 and at the main site is a cisco 2651 ixm

A sniffer like Etherpeek would work. The 2651 should support NetFlow, but I suspect the 837 doesn't. You could also look at setting up QOS, which would be a good long-term solution.
