Thus spake Karl Denninger
I will remove those blocks when I can PROVE that they can no longer be used
as a smurf amplifier. To date, NOBODY on the list has come forward and said
"we've audited and fixed, please remove the block".
I have got one site to fix their routers. It's the DISA Information Systems
Center on netblock 18.104.22.168. I explained the situation and gave them
a few pointers. A few days laterthey had fixed it and they no longer
act as an amplifier. Very satisfying.
Another one, 22.214.171.124, bounced my email but they seem to have fixed
their routers anyway. Perhaps someone local called them up and harrassed
them about it.
PSU (which is on the list) said "we're looking into it" but that was more
than two weeks ago! How long does it take to telnet into your routers and
check the ethernet interfaces for the correct configuration? A day or so?
Perhaps, even if you have a HUGE netwokr.
Perhaps when pointing at problem networks, just mention the netblock.
That way we can compare it with our own lists.
Here's one that seems particularly troublesome and I know it is in your
list as well.

Looks to me like they have been running on autopilot for 5 years. I
sent email to the contact addresses and, since I had doubts that they
were valid addresses, I copied root and hostmaster. Root and hostmaster
bounced and the others seem to have been completely ignored. Perhaps
someone closer to them can poke around and see what the situation is.
This is great because each success has a significant overall effect.
