Having just got my adsl line, with a Smoothwall (linux-firewall) box
feeding a house-side net of 2 or 3 machines, I'm looking nervously at
the intrusion detection log...
It started showing significant activity yesterday - (3 of the early
instance appeared to be from Mr Demon, but there were also a couple of
reports of MS-SQL worms...)
Then towards the end of the day I started getting 'potentially bad
traffic' from 127:0.0.1:80 (!) to my new adsl demon IP at high ports
(eg, this morning it's here again, to port 1286)
In all these instances I've had an NT box or two up as well as my main
linux-box.
Is it possible that these packets are internally generated, so I don't
need to worry,
or has demon-adsl really got spoofed packets from the loopback address
flying round on it (as the ref. to a note on
www.sans.org in the
smoothwall log would suggest)???
