NANOG 45 Lightning Talks Open
by Todd Underwood 08 Jan '09

08 Jan '09

On behalf of the rest of the NANOG Program Committee, I'm pleased to announce that submissions for Lightning talks for NANOG 45 are open at: http://www.nanogpc.org/lightning/ Lightning talks are short presentations (no more than 10 minutes, including questions) of topics that are either too short, too timely or too preliminary to include on the general agenda. In the past, these have been some of the most popular presentations at NANOG, For this upcoming conference in Santo Domingo, we have lightning talk slots available on all three days. The Program Committee will pick the first three of these prior to the conference (by the end of next week, in fact), so please get your submissions in by Wed, 14 January for the best possible consideration. We already have several submissions, but would appreciate more, of course. Rest assured, however, that we will continue accepting lightnings talk proposals (and voting on them) through the conference, as timeliness is part of what makes lightning talks so great. The sooner you submit, though, the better your chance to present. See all of you in Santo Domingo. Todd Underwood Chair, Program Committee, NANOG

Ethical DDoS drone network
by Jeffrey Lyon 07 Jan '09

07 Jan '09

Say for instance one wanted to create an "ethical botnet," how would this be done in a manner that is legal, non-abusive toward other networks, and unquestionably used for legitimate internal security purposes? How does your company approach this dilemma? Our company for instance has always relied on outside attacks to spot check our security and i'm beginning to think there may be a more user friendly alternative. Thoughts? -- Jeffrey Lyon, Leadership Team jeffrey.lyon(a)blacklotus.net | http://www.blacklotus.net Black Lotus Communications of The IRC Company, Inc.

question about BGP default routing
by Kai Chen 06 Jan '09

06 Jan '09

Hi all I have a question: I see very few prefixes in a routing table and combining the prefixes does not cover addresses space, for example, {78.41.184.0/21, 91.103.239.0/24, 91.103.232.0/22, 82.138.64.0/23, 91.103.232.0/21, 77.95.71.0/24} are all prefixes I observed from a BGP speaking router, I am just asking is this router using a default routing for all the other destinations? Thanks a lot

I cant believe this .. http://www.iprental.com Looks like anonymizer combined with what looks almost like a "rent a botnet", legit nodes (you sign up to download a client that makes you part of this botnet, etc) http://www.iprental.com/technical/ Speaking of a "commercial botnet"", there was something similar earlier - but that was a "download this bulk mailer" type operation, guys called Atriks, who got tracked so extensively by spamhaus that they seem to have kind of disappeared now. --srs

Security team successfully cracks SSL using 200 PS3's and MD5 flaw.
by Rodrick Brown 06 Jan '09

06 Jan '09

A team of security researchers and academics has broken a core piece of Internet technology. They made their work public at the 25th Chaos Communication Congress in Berlin today. The team was able to create a rogue certificate authority and use it to issue valid SSL certificates for any site they want. The user would have no indication that their HTTPS connection was being monitored/modified. http://hackaday.com/2008/12/30/25c3-hackers-completely-break-ssl-using-200-… http://phreedom.org/research/rogue-ca/ -- [ Rodrick R.

IPv6: IS-IS or OSPFv3
by devang patel 05 Jan '09

05 Jan '09

Hello, I do have some confusion about which one is better for IPv6 in Service Provider networks as far as IP routing and MPLS application is concern! 1. Which protocol should i use to support the IPv6 in network: ISIS or OSPFv3? As ISIS has multi-topology feature that can give us capability to run IPv4 network separate from IPv6 right! and same thing with OSPF: OSPFv2 will be used for IPv4 routing and OSPFv3 will be used for IPv6 routing! again Its look like resource utilization for both the protocol will be same as they are going to use separate database for storing the routing or topology information. ISIS still has advantage over OSPF as it does use the TLV structure which can help in expanding network to support the new feature! 2. MPLS is not distributing label for IPv6 protocol so again there will not be any IGP best path calcuated for any MPLS related application for IPv6! 3. what if i have already running OSPFv2 for IPv4 in the network then should i think for migrating to ISIS? if yes then what are the advantages that I can look at for migrating my network to IS-IS? regards Devang Patel
