           Summary: Network history graphs show meningful network activity
                    even with wireless turned off
           Product: kde
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: benderamp at gmail.com


Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

KDE 4.3.90 (KDE 4.4 RC1) from opensuse factory.

After updating from beta 1 I have noticed that network monitor plasmoid (I have
it in the panel - show wireless, no ethernet connections) always shows active
outgoing and incoming traffic even though I have no evident network activities
- all torrents are stopped, no loading pages in konqueror etc. System monitor
Network History shows same activity.

"sudo lsof -i | grep ESTABLISHED" and "sudo netstat -A inet --program" show no
active connections.

I have killed all konqueror instances, closed ktorrent, amarok and even killed
plasma-desktop - the result is the same.

I have started to think that I have a kind of rootkit in my system which hides
its process from lsof and netstat utils, but after switching off wireless (by
hardware button) network monitor still showed network activity (the result
changed from waves to straight line, but still with non-zero value).

Another good sign for me is that gnome network monitor also does not show such
network activity.

Currently KDE network monitor shows me 1Gb/s incoming traffic and 0.36Gb/s
outgoing, and gnome network monitor shows 0 for outgoing and 58bytes/s changing
with 0 each second for incoming (see attached screenshot).

I also did not have this on beta1.
