I've been monitoring the traffic for my other server that is located somewhere else..
There is some strange traffic which seems somehow realted to the network.
quite regulary the are 11bits send or recieved from/to 145.145.22.190, which resolved to GE3-1-0.1672.JNR01.Asd002A.surf.net
the isp is also surfnet...
I'm wondering if this is some dns request or something else. google has nothing to tell about this ip...
scanning with iftop is quite nice, although it does not display a port for that ip, all other entries do have ports, meaning this is some strange traffic.
Sinse this traffic seems to come from eth4 it means the octadisp server(school project) is to blame, running ubuntu..
i'll investigate further
