Have just got my ADSL service back and in less than 2 days have seen nearly 3Gb usage from only 2 clients. Whilst some of this is easily explained most is not. Wireless is tied down and unlikely to have been hacked.
Are there any free/ opensource tools that would tell me more than the Member Centre Pages that will help identify what apps on what machine are consuming/ generating the most Bandwidth? One client is a Mac running Tiger. The other runs XP and another recently installed box runs Vista. Ideally, I a looking for something I can leave running on the laptop plugged directly into my netgear router.
