That time it seems to be only scanning and trying to connect to freifunk
(without having it told to) for some reasons what somehow does not work.
What is running here:
|-nodm,2722
| |-Xorg,2727 :0 -nolisten tcp vt7lay managers and xinit (startx)
| `-nodm,2753
| `-sh,2754 -l -c /etc/X11/Xsessionusinow $
| `-loginwindow,2758
| |-iwlist,3013 wlan1 scanning
| `-ssh-agent,2775 x-session-manager
Of course this does not happen everyday.

Andreas
