View Full Version : what would cause this much uploading?
I've had my laptop connected to the uni network (10Mbps) for today and haven't been doing anything special on it, Bit torrent is running but not exactly uploading much. The internet connection is limited to 512 down 256 up (very very annoying) so I doubt its internet traffic, yet the firewall is on as shown in the pic below.
In the last couple of hours I have been using remote desktop to control my PC, but all thats been doing is playing music, nothing special. I've also copied across 7gigs of X files episodes from my PC to my laptop and still the received packets are far smaller in quantity than the sent ones :confused:
anyone got any ideas?

I've seen it before though
Jamez 25-09-2005, 10:34 AM Just do all adware/spyware checks, virus checks, as you SHOULDNT be uploading 4 gig, christ on a 256 up aswell, somethings deffo wrong.
mark0x 25-09-2005, 12:54 PM It's a bug like I said, nothing to do with spyware or anything
2^32 = 4294967296
his figure of 4297357545 - 4294967296 == 2390249 packets == xxx bytes == real value

Ur just saying that :beam: :beam:
i woudl do a virus check, spam check and run something like root kit releavler over the machine to make sure you havent got anything.
PS i wouldnt run bit torrent over a uni network, it wont make you very popular
I'm certain the machine is clean, and I'm using BT to try and get hold of the latest Debian release but its proving to be a painfully slow process.

It appears for half a second then disappears because it causes an exception hehe :)
Bottom line: don't trust those numbers, use a 3rd party tool to monitor the connection

Sorry for not explaining it but I thought TomG would understand
2^32 is the maximum value an unsigned 32bit integer can hold, usually when you see a strange number and it's around that size, it's to do with an integer boundry/wrapping bug or suchlike
A few years ago I wrote a popular IRC addon called moo.dll before WMI et al became available, a few versions of it later I was forced to create a lightweight resident helper application (moohlp.exe) to keep track of network statistics as Windows likes to limit you to a 32bit number which wraps at 4GB (2^32)!
That will be the crux of this problem unfortunately, somewhere along the line someone either isn't initialising a counter properly or it is of insufficient size and is wrapping with unexpected results
