The "Nachi" worm propagates via MSRPC DCOM and the IIS WebDAV bug. It may be causing this storm because it runs 300 scanning threads, and it pings each IP first. http://xforce.iss.net/xforce/alerts/id/150 MS Blast wasn't multithreaded.

RE: Natural Gas Generator manufacturer opinions? (might be off topic?)

Capstone and Ingersoll-Rand NG turbines seem to be in favor these days among the paranoid. http://www.capstoneturbine.com/ http://www.irpowerworks.com/ These may be up to 2x the cost of a diesel, but they run forever, you can put them anywhere, they always start, and the fuel never gets fouled. For installations large enough to care about tank pressure, heaters are an option, but then there's the question of how you power the heater... :) Regards, Andrew Bender taqua.com -----Original Message----- From: Jeffrey Wheat [mailto:jeff@cetlink.net] Sent: Tuesday, August 19, 2003 9:47 AM To: Drew Weaver; nanog(a)merit.edu Subject: RE: Natural Gas Generator manufacturer opinions?

>Capacity isn't the problem. The problem is that there aren't enough lines >between the providers and consumers to carry the current volume. >Eric A. Hall Exactly, and everyone on this list should realize this exists in EVERY utility. A quote from CNN.com, Money section: "However, the wireless telecom sector has many problems. Most carriers are faced with large debt loads. And because of intense competition (there are six major carriers nationwide) they are resorting to price wars to attract new subscribers. All that means that it has been difficult for the carriers to upgrade their networks to handle more calls and will probably remain so for the foreseeable future. "It will be years before wireless carriers are at a level where they can handle the type of volume that landlines can," said Allan Tumolillo,chief operating officer of Probe Group, a telecom research firm." So, wireless failed to guarantee service because they lacked the economic incentive to do so, which meant people couldn't call during a blackout caused because Power wasn't economically incentivized to do so either.

AT&T US Network Slowdown?
by Paul Jasa 19 Aug '03

19 Aug '03

Dear Nanogers, Is anyone aware of a "slowdown" issue throughout the US AT&T network since 8/18 at around 4pm which is causing a lot of internet circuits (including DSL) to be inaccessible and/or appear down from the outside world? AT&T says this has been escalated to "Level 4" with no ETA and affecting the whole country. I am seeing this problem in the San Francisco area. Just wondering if anyone else is experiencing anything that would confirm AT&T's claim, and fishing for more info about the possible cause and ETA. Thanks!
