Many thanks to the group for pointing me toward ZA.

Just a quick question and apologies if this is rather a dumb
one, but why are there so many 'pings' at my PC - literally
hundreds of them? A few I could understand, but so many?

The majority of them seem to come from ******.dsl.pol.co.uk.

Regards

B.

Brian,
From http://www.tldp.org/HOWTO/Security-Quickstart-HOWTO/firewalls.html

the following:

"Firewall logs tend to generate a fair amount of each. Of course, you
are wanting to stop only the "bad", but you will undoubtedly catch
some harmless traffic as well. The 'net has a lot of background noise.

In many cases, knowing the intentions of an incoming packet are almost
impossible. Attempted intrusion? Misbehaved protocol? Mis-typed IP
address? Conclusions can be drawn based on factors such as destination
port, source port, protocol, and many other variables. But there is no
substitute for experience in interpreting firewall logs. It is a black
art in many cases."
