IS-IS protocol implementation problem
by Sean Donelan 29 Oct '00

29 Oct '00

Network operators using IS-IS on Cisco should be aware of a problem which can result in their routers reloading unexpectedly when a corrupt IS-IS packet is received. Cisco has fixed the problem in various 12.0 software trains. The problem can cascade through a single provider's network. Because IS-IS is an IGP protocol, it does not propagate between providers. This has already affected a provider. I haven't found out what is originating the bad IS-IS packet, i.e. is this an inter-vender operability issue?

NMAP/TBIT
by Jitendra Padhye 28 Oct '00

28 Oct '00

Dear NANOG mailing list: We gave a talk at NANOG earlier this week in Washington, D.C., in which we reported on our development of TBIT (the TCP Behavior Inference Tool) for testing the TCP behavior of web servers in the Internet. We also raised the issue of running NMAP to help us correlate TCP behaviors with operating systems. The purpose of this correlation is so that any bugs identified by TBIT can be appropriately reported and fixed. One suggestion made at NANOG was that we send email to this mailing list to inform people when we are running large-scale NMAP scans. So the purpose of this email is to say that, over the weekend, we will be running NMAP against 20,000+ IP addresses from machines in bind.com domain, kindly provided to us by Aaron Hughes. If you have any problems with this, please contact us (padhye(a)aciri.org, floyd(a)aciri.org) instead of flaming Aaron :) Here are some URLs for more information: ACIRI: http://www.aciri.org/ TBIT: http://www.aciri.org/tbit/ NMAP: http://www.insecure.org/nmap/ Regards, - Jitendra Padhye and Sally Floyd. ---------------------- http://www.aciri.org/ ----------------------

Thank you very much for the effort Hans.

The Cidr Report
by Tony Bates 27 Oct '00

27 Oct '00

This is an auto-generated mail on Fri Oct 27 12:00:00 PDT 2000 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
