DNS problem at NANOG18
by takei＠csm.jcsat.co.jp 07 Feb '00

Can someone setup DNS lookup dabase for DHCP address pool in NANOG18? Currently, I can get right DNS reverse look up, but normal DNS lookup looks like has not been setup. My server refuse connection, because they can get hostname from DNS but cannot resolve IP address from DNS. Thank you. --- Jun Takei NTT Satellite Communications Inc. Japan Satellite Systems Inc.

Is it just me, or is the audio in the real stream corrupt? Also, the audio in the H.261 stream is a bit distorted. Perhaps the input level to the machine generating the stream need to be turned down? -David

Guess there are bugs in that technology then. My name server was 207.151.19.6. Dirk On Sat, Feb 05, 2000 at 10:44:21PM -0800, Nicholas W.

Reminder: BOF on Distributed DoS, San Jose 2/7/00
by David Kennedy CISSP 06 Feb '00

06 Feb '00

The purpose of this message is to solicit participation in birds of a feather (BOF) session to discuss the Distributed Denial of Service (DDOS) problem. WHO: Everyone interested in aggressively addressing a category of attack threatening Internet-connected systems. WHAT: We (ICSA.net ) are have put together at least two BOF's to discuss DDOS attacks in the trin00, TFN, TNF2K, stacheldraht...family. WHEN & WHERE: The next BOF session will be Monday, February 7, 2000 from 7 to 9 pm at Doubletree Hotel San Jose, 2050 Gateway Place, San Jose, CA - phone 408-453-4000 (conference hotel). Refreshments will be served. This BOF session coincides with the North American Network Operators Group (NANOG) conference and a meeting of ICSA's ISPSec Consortium, but the BOF is open to all interested parties. WHY: The goals are two-fold initially, awareness of the problem and see if the collection of smarts at a BOF can suggest effective ways of dealing with these attacks other than "hoping" the clue-challenged secure their systems before the trojans are installed. relevant URL's: http://www.icsa.net/html/communities/ispsec/ http://www.nanog.org/mtg-0002/ http://www.washington.edu/People/dad/ http://www.ietf.org/internet-drafts/draft-moskowitz-hip-01.txt http://www.ietf.org/internet-drafts/draft-moskowitz-hip-enc-00.txt http://www.ietf.org/internet-drafts/draft-moskowitz-hip-dns-00.txt http://www.ietf.org/internet-drafts/draft-moskowitz-hip-arch-01.txt Tentative Agenda: Introduction: The Problem: Technical Review of Attack tools Trends/ Implications/ Characteristics Possible Mitigations: Scanning for Master / Slaves ISP Egress /Ingress Filtering Potential Protocol Changes HIP Open discussion Next Steps Noteworthy Participants: Dave Dittrich Bob Moskowitz -- Regards, Dave Kennedy CISSP Director of Research Services, ICSA.net http://www.icsa.net Protect what you connect.

Worldcom and Qwest switch places
by Sean Donelan 05 Feb '00

05 Feb '00

Several people sent me reports about switch troubles in Los Angeles in January. I thought I had tracked it down to a problem in the AT&T network. But Qwest also had an switch problems in Los Angeles and elsewhere for 11 days in January. NetworkWorld reported Qwest is using Lucent switches, but had old software on some of the switches. Lucent had no comment, except to say the same switches are the same hardware used in many of the world's largest service provider networks. A worrying comment, since this is at least the second time Lucent hardware has been involved in a multi-week problem. Since Lucent equipment was also involved in the 10 days of Worldcom problems, is there a common root cause between the Worldcom's problems and Qwest's problems? Is there some lesson other providers should be learning from these events? Or is each service provider expected to learn and re-learn these lessons individually? Is there some network design decision engineers are getting wrong?

Or are people just massively over-provising their >web sites, and praying? The following is off the record and I cannot divulge the client's name. Hoever, FYI... I was managing the applications team for one of these sites. We had little warning of the ad (found out about it via some of the press descriptions of e-commerce sites and the superbowl rather than from the client). As far as I know nobody had a real marketing prediction at traffic increase due to the ad. Site was designed with some margins for peak traffic early next year and has been running at predicted this year traffic in general, about 1/3 of design capacity. We saw a blip, but only a small one, during game time. It looks like people who were watching the game were watching the game, not geeking. Since nobody had something of the nature which would grab typical football fan's attention (Victoria's Secret ad) this time around, it looks like the direct impact was low. -george william herbert gherbert(a)crl.com
