I saw, but, I never ping-ed such address, so why this entries into my
log files? I know that smootwall protects my network from the outside,
but what this log means? I suppose there is a program that try to ping
that address. How can I discover the program that create this traffic?
After this, probably I'll configure my smoothie to limit the outgoing
traffic too.
