Re: Do I have a security problem?
Either a modem (example: dial up with 54k, analog or isdn) or a modern router (dsl, cable) has always activity.
They 'talk' things like:
Your modem: Hey i'm here and my MAC (hardware adress) is XY, but internaly my name is 192.168.x.x.
Internet: Got you, your MAC and name is. ...
Are there any working at your location?
By working i mean, anything that is worked on near you, wether that may be on the street, or the wired up in the air.
Or are you living in a older house/apartment (pre 1970)
This may cause weaker signals, which will increase packet trafic, which will be visible by more lights flashing.
Dont know if that helps, but you could run one of these commands to see if there are any unkown sessions:
users (note, each terminal shows as a new user! So if you have 20 terminals open, you'll see yourname 20 times. If one of them is loged as root, root will be shown instead of your name)
top -u 0 (to list process ran by root)
top -u 500|1000 (to list process ran by default user 500 for f15 and below, 1000 for f16 and up)
