Due meter is no good if their is an internal network unlees they all go through one computer.
MRTG is the best but will not work with NTL coz they block the IP number it uses to log the uploads and downloads.
I have been on about this for months on .com with no luck. I have even said NTL should supply this function for members to mnitor their useage if they wished.
I do nkow that Blueyonder allow this to work and one person who uses MRTG to monitor his bandwidth has it online
here looks really good shame NTL block this function perhaps if others got together we could start contacting NTL as a group and not individual people.
