Ph.D. student looking for data on network failure causes
by David L. Oppenheimer 08 Apr '02

08 Apr '02

Hello network operators! I'm a Ph.D. student at UC Berkeley working for Dave Patterson on the ROC project, which is investgiating techniques for improving the availability and manageability of large-scale Internet services and systems. I'm currently conducting a study of the root causes (hardware, softare, human, etc.) and durations of failures in such systems. To do this, I have been examining the operations trouble ticket databases from several large-scale Internet services (of the Hotmail, eBay, Yahoo!, etc. type). In doing this research, it has become apparent that for many services (especially geographically distributed ones, e.g. those that use multiple colocation facilities), a major cause of problems is failures of various types in the Internet. Thus I've become interested in finding out the types and root causes of problems in wide-area networks, e.g. within the kinds of large-scale ASes that are administered by the folks on this list. I'm not sure how your services track failures and problems; the problem tracking databases at the services I've examined have been a great source of data about problem scale, symptoms, root causes, durations, steps (and missteps!) taken in diagnosing and fixing problems, etc. I'm writing to the list because I'm very interested in working with network operators to study the causes of failures in large networks. I realize this type of data is very sensitive to your organizations. I would be happy to talk offline with anyone who is interested in the possibility of sharing data, about how I've overcome the multitude of objections that have been raised by folks I have solicited for data (protecting their customers' privacy, securing datasets when they are not examined on the premises of the services, anonymizing and aggregating data in reporting, etc. etc.). I'm interested in the relative causes of failures, *not* overall availability numbers. As a result of the precautions we've taken, several household-name Internet services have allowed me to examine and report on the problems their servcies have experienced. If you're interested in discussing the possibility of sharing access to this kind of data about your service, please contact me. I'm willing to examine data on the premises of your service, to anonymize it fully, to submit any results I want to publish to your organization prior to publication, to sign any necessary NDAs, etc. In return, I'm happy to share with you any insights I have about the problems your service experiences, and you'll contribute to the world's knowledge of why bad things happen to good networks. :-) If you're not the right person in your organization to contact with this request, but you think your organization might be interested in participating in this study, perhaps you could forward this email to the appropriate person or let me know who the right person to contact in your organization would be. Many thanks! David

NANOG on Trial
by Paul Revere 08 Apr '02

* To: isp-colo(a)isp-colo.com * Subject: Legal Recourse * From: "Nick Catalano" <nick(a)nozone.net> * Date: Sat, 6 Apr 2002 19:07:46 -0600 Recently my personal system has been attacked by someone from the IRC channel #nanog on EFNet. This along with multiple instances of showing/providing pornography to minors as well as defamation of character/slander as well as numerous other civil and criminal items have really plagued my past 3 months. I think it's time to look into fighting back. Other than to warn others of the pending danger of dealing with the immature people found within that channel, I would love to know what all legal recourse I have in this matter. I have a lawyer but I am not quite ready to sue. I fully expect to get flamed by this, of course. Yet I also expect most of those who flame me to be from Nanog. I don't care how you play the game, but if you try to play me you can burn in hell. Strong words from a person who isn't going to take it anymore. - Nick Catalano nick(a)nozone.net n|Catalano Ventures :: The Next Generation is Coming Soon __________________________________________________ Do You Yahoo!?

ANN: 0.1-final release of Panoptis DoS/DDoS detection software
by Constantinos A. Kotsokalis 08 Apr '02

08 Apr '02

Hello all, first of all I would like to thank everyone who downloaded and tested the beta-5 version of Panoptis. After killing that last bug (which was still in beta-5, contrary to my belief) the first stable release (0.1) is out. I have it running for 5 days, it works like a charm. You can download it from: http://prdownloads.sourceforge.net/panoptis/panoptis-0.1.tar.gz Please keep in mind that: 1. The peer module (thread) is not activated yet, it needs testing. However, that does not affect a node's ability to detect attacks. 2. The NetFlow V8 code has not been tested *at all*. It probably isn't working correctly. V1 and V5 should be ok. 3. Unfortunately it is still working only on Linux (tested on kernel 2.4.x, glibc 2.2.x). The ports to Solaris and FreeBSD are still worked on. 4. I can make no promises as far as its effectiveness is concerned. It is working fine for me at the moment though. If you try it and find any problems, please let me know (ckotso(a)grnet.gr) I would also like to listen to ideas anyone may have, regarding future directions and implementation of new functionality. Thanks, Costas -- Constantinos A. Kotsokalis || ckotso(a)grnet.gr Greek Research and Technology Network Tel: +30 10 7474243 && Fax: +30 10 7474490
