This post is a plea for help from smart network administrators/geeks and/or Bob Metcalfe:
Like a lot of dads, I’m the on-site technical support for my household and while that job used to just involve keeping software updates fresh on a single desktop computer, dads like me now have a whole clutch of computers and other gadgets (DVD players, refrigerators, tablets, laptops, TVs, cameras) – all of which have IP numbers — and all of which are used by any one of four family members to gobble up bandwidth. Like a like lot of Canadians who get their Internet service from a major cableco/telco, I have a bandwidth cap. Exceed the cap and the Akin household pays through the nose. That makes the Akin household’s Accounts Payable Manager (my wife) very unhappy with On-Site Technical Support (that would be me.)
So I need help. Let me describe the genesis of today’s plea for help:
Checking the daily log my ISP keeps of the bandwidth consumed by our household we found that yesterday we gobbled up a whopping 17GB of incoming data. 17GB in one midnight-to-midnight period! For the life of me, I can’t figure out which device (or household member) was the big hog. So far as I can tell, the household members have fessed up to:
- One child watched about two hours of YouTube videos on his iPod.
- Two children played about six hours worth of Minecraft (Is Minecraft a bandwidth hog?)
- On-site tech support (me) updated printer drivers (250MB tops)
- There was the usual e-mail/Web surfing/social media participation which is usually good for about 2 GB
But we used 17GB! (Our previous single day high was 9 GB. Our 24-day average is about 5.5 GB) No one downloaded a movie or a single MP3. There are no servers running in the household. The wireless network is locked up good-and-tight. The network name and password are changed twice monthly.
So why and how did 17GB of data get into our household?
What would make solving this puzzle easy is a software tool that could be installed at the router (Cisco DPC3825 DOCSIS 3.0 Gateway, if you were curious)) that would do this:
1. Log inbound Internet packets/bytes and identify target device of that inbound traffic.
2. Alternatively, some utility on each Internet-capable device in our household that could track how much data it receives from the Internet (as opposed to how much data it receives from other devices on the wireless LAN) would also be useful. That said, we have, for example, an Interent-enabled television, Internet-enabled DVD players, and Internet-enabled gaming consoles and I’m not sure I would even know how (let alone have permission) to modify the software on my DVD player.
So the router route seems the best one. So that at the end of the day I can get my router to provide me with this report:
SUMMARY FOR [DATE]-------------------------DEVICE INBOUND MBDVD 1 892DESKTOP 1 3133TABLET 1 1202SMARTPHONE 1 808LAPTOP 1 1445
And so on … This way, I could track which device was responsible for sucking down most of that 17GB and then, in turn, probably triangulate the user…
So geeks: Anything out there that can help me track how much Internet is being gobbled up by each device on my local WAN?
