IANA DNSSEC Testbed to be Decommissioned
by Joe Abley 03 Aug '10

03 Aug '10

Colleagues, ICANN has operated the IANA DNSSEC testbed, serving non-production, signed versions of the root, ARPA, IN-ADDR.ARPA, IP6.ARPA, IRIS.ARPA, URN.ARPA, and INT zones for several years. Following the recent completion of DNSSEC deployment in the root zone, this testbed is scheduled to be decommissioned. For more details on the IANA DNSSEC testbed, see <https://ns.iana.org/dnssec/>. For more details on DNSSEC deployment in the Root Zone, see <http://www.root-dnssec.org>. At the time that the service is decommissioned, the nameserver bound to NS.IANA.ORG (208.77.188.32, 2620:0:2d0:1::32) will be shut down and DNS queries to NS.IANA.ORG will fail with ICMP type 3 code 3 (Destination Unreachable, Port Unreachable). We suggest that anybody using the DNSSEC testbed for anything resembling production services make plans to stop doing so at their earliest convenience. ICANN would like to thank Packet Clearing House (PCH) and Dun.com DynTLD for their support and generous donation of global DNS resources to the IANA DNSSEC testbed. DRAFT TIMELINE Wed 2010-08-03 First public notice (this message) Wed 2010-08-25 Second public notice (reminder) Wed 2010-09-01 IANA DNSSEC Testbed is shut down Wed 2010-09-01 Third public notice (confirming work complete) Regards, Joe Abley Director DNS Operations, ICANN

I'm not aware of an enhancement to set the cluster-id on a per-vrf basis, it is currently global..

DNSSEC Launched Today by EDUCAUSE and VeriSign
by Matt Larson 02 Aug '10

02 Aug '10

With Becky Granger's permission, I'm pleased to share the announcement below. Matt ----- Forwarded message from Becky Granger <rgranger(a)educause.edu> ----- From: Becky Granger <rgranger(a)educause.edu> Subject: [Dnssec-deployment] DNSSEC Launched Today by EDUCAUSE and VeriSign To: dnssec-deployment(a)dnssec-deployment.org, DNSSEC(a)internet2.edu, dnssec(a)educause.edu Date: Mon, 2 Aug 2010 11:06:01 -0600 Hello all - I wanted to let you know that DNSSEC is now supported in the .edu domain. Please feel free to pass the word! --Becky Becky Granger, CAE Director, Information Technology and Member Services EDUCAUSE - Uncommon Thinking for the Common Good (303) 939-0334 www.educause.edu EDUCAUSE Annual Conference - The best thinking in higher ed IT October 12-15, 2010 | Anaheim, CA www.educause.edu/e10 -----Original Message----- From: EDUCAUSE [mailto:educause@educause.edu] Sent: Monday, August 02, 2010 10:32 AM To: Staff Subject: DNSSEC Launched Today by EDUCAUSE and VeriSign FOR IMMEDIATE RELEASE Contact: Greg Jackson Vice President EDUCAUSE gjackson(a)educause.edu 202-331-5351 *********************************************** DNSSEC Launched Today by EDUCAUSE and VeriSign *********************************************** August 2, 2010, Boulder, Colorado--EDUCAUSE and VeriSign announced the deployment of a security system known as Domain Name Security Extensions (DNSSEC) within the .edu portion of the Internet, which EDUCAUSE manages under a cooperative agreement with the U.S. Department of Commerce. Institutions whose domain names end in .edu will now be able to utilize digital signatures to mitigate certain DNS security vulnerabilities, such as cache poisoning and man-in-the-middle attacks. The Domain Name System (DNS) is the part of the Internet that translates names such as "example.edu" into numeric addresses (for example, 198.59.61.90). All Internet applications-from electronic mail to online banking-depend on the accuracy and integrity of this translation. Over the years, Internet security experts have discovered a variety of ways that DNS translation may be compromised. The DNSSEC security system limits the problem by allowing owners of domain names to use digital signatures to add an extra level of authentication to the translation process. Deploying DNSSEC for .edu furthers the initiative to enhance domain name security throughout the broader scope of the internet. As a precursor to deployment, EDUCAUSE and VeriSign hosted a testbed environment which allowed end-to-end testing by selected .edu domain holders in a non production environment. Brian Voss, vice chancellor for IT and CIO at Louisiana State University and current chair of the joint EDUCAUSE/Internet2 Higher Education Information Security Council, noted, "I am proud that LSU is at the forefront of this exciting development and that our contributions and efforts as a testbed for .edu deployment have laid a foundation for the ubiquitous adoption of DNSSEC, so that the research and education community can eventually realize its full value," Voss also added, "DNSSEC represents an evolution in Internet reliability and security, and I know that my CIO colleagues recognize that our university communities expect our networks to be secure, and improving the security of our root Domain Name System through cryptography is something we all will embrace." EDUCAUSE President and CEO Diana Oblinger said, "EDUCAUSE has appreciated the opportunity to work with VeriSign and the U.S. Department of Commerce to advance the security and integrity of the Internet through early testing and deployment of DNSSEC. Dating from the creation of ARPANET through the present day, the higher education technology community has played a leading role in the development of the Internet as a platform for learning, discovery, and engagement. We have been happy to continue that role by being a lead partner in the launch of DNSSEC." Pat Kane, vice president of VeriSign, stated, "VeriSign's partnership with EDUCAUSE to test and deploy DNSSEC in the .edu domain demonstrates our ongoing commitment to a secure Internet infrastructure. VeriSign appreciates the close collaboration with EDUCAUSE and the U.S. Department of Commerce that allowed for success with this process and the opportunity to generate lessons learned which we are actively sharing with other domain registrars, thereby enhancing overall Internet security." ************************************* About EDUCAUSE EDUCAUSE is a nonprofit association and the foremost community of IT leaders and professionals committed to advancing higher education. EDUCAUSE programs and services are focused on analysis, advocacy, community building, professional development, and knowledge creation because IT plays a transformative role in higher education. EDUCAUSE supports those who lead, manage, and use information technology through a comprehensive range of resources and activities.

Cisco ASR BGP within the box question
by Steven.Glogger＠swisscom.com 02 Aug '10

02 Aug '10

hi all just a short question (related to a quite new feature from cisco). with the new cisco ASR software (15.0(1)S - released some days ago) it is able to do BGP on the same box. we need this feature because we use the VASI interfaces to bring and filter traffic from one VRF to another VRF and performing firewalling (ZBF). basically we have on the box: [VRF_A via vasileft1]--[VRF_B via vasiright1] and the box itself speaks BGP on VRF_B with some RR's: [ASRBox] ---- (RR) ---- [anotherbox] the fun part is, if you want to announce (e.g. 0.0.0.0/0) from VRF_B (announced from anotherbox) to VRF_A it should be possible now with that new feature. according to BGP I need to configure the VRF_A peer as route-reflector-client so the routes from the anotherbox get reflected via RR to VRF_B. but, it seems that the router itself needs to be tricked, since he thinks that both peers are in the same route-reflector cluster ("DENIED due to: reflected from the same cluster"): Aug 2 13:35:03: BGP(0): 213.3.246.33 send UPDATE (format) 0.0.0.0/0, next 10.62.112.65, metric 0, path 44038 3303, extended community RT:65501:1702 Aug 2 13:35:03: BGP(0): 213.3.246.34 rcv UPDATE w/ attr: nexthop 10.62.112.65, origin i, localpref 250, metric 0, originator 10.62.112.65, clusterlist 10.62.112.79 10.62.112.17, merged path 44038 3303, AS_PATH , community Aug 2 13:35:03: BGP(0): 213.3.246.34 rcv UPDATE about 0.0.0.0/0 -- DENIED due to: reflected from the same cluster; Aug 2 13:35:03: BGP: 213.3.246.34 Modifying prefix 0.0.0.0/0 from 0 -> 4 address so, this is my config: config: <snip> interface vasileft1 ip vrf forwarding VRF_A ip address 10.0.0.1 255.255.255.252 zone-member security VASILEFT ! interface vasiright1 ip vrf forwarding VRF_B ip address 10.0.0.2 255.255.255.252 zone-member security VASIRIGHT ! router bgp 65501 address-family ipv4 vrf IABIP- bgp router-id 10.0.0.1 redistribute connected redistribute static neighbor 10.0.0.2 remote-as 65501 neighbor 10.0.0.2 update-source vasileft1 neighbor 10.0.0.2 activate neighbor 10.0.0.2 send-community both neighbor 10.0.0.2 next-hop-self exit-address-family ! address-family ipv4 vrf IACYP- import path selection multipaths bgp router-id 10.0.0.2 redistribute connected redistribute static route-map SET-PREFIX-SoO neighbor 10.0.0.1 remote-as 65501 neighbor 10.0.0.1 update-source vasiright1 neighbor 10.0.0.1 activate neighbor 10.0.0.1 send-community both neighbor 10.0.0.1 next-hop-self exit-address-family </snip> what does not works: - having another AS number on the same box (otherwise eBGP would be possible) - client-to-client reflection - magic stuff in route-map - setting different cluster-id's for different address-families - nothing found in the release notes: http://www.cisco.com/en/US/docs/ios/ios_xe/3/release/notes/asr1k_rn_3s_rel_… so, does anyone knows a nice hidden command to disable this cluster-checking on a per-peer basis or so? -steven

[NANOG-announce] 2010 NANOG election timeline
by Steve Feldman 02 Aug '10

02 Aug '10

Hello NANOGers! Per the charter, we are approaching the annual NANOG election and appointment time. In addition to the series of "call for nominations" messages at the opening of each period, we thought to send an overview and time line ahead of the actual nominations opening. Hopefully this will get more of the eligible members of the community to consider standing for a role in one of the Committees that helps makes NANOG what it is. All nominations should be sent to nominations(a)nanog.org. The election timeline is: Aug. 2 - SC Nominations begin Aug. 24 - Charter discussed in Futures Aug. 24 - PC Nominations begin Aug. 30 - SC Candidate information posted/nominations close Sep. 13 - Call for Mailing List Committee nominations Sep. 21 - Ballot approved Oct. 3 - Voting opens at 12:00 EDT Oct. 4 - PC Candidate Information posted/nominations close Oct. 6 - Voting closes at 09:15 EDT, results announced before the close of NANOG 50. NANOG Steering Committee The NANOG Steering Committee works closely with Merit to promote, support and improve NANOG. The Steering Committee is responsible for the selection of the Program Committee and the Comunications Committee, and is the community's instrument for ensuring that the NANOG organization remains open, relevant and useful. Elections for three of the seven positions on the Steering Committee will be held in October 2010. The currently-serving Steering Committee members whose terms are expiring are Patrick Gilmore, Joe Provo, and Rob Seastrom. Joe has served two consecutive terms so per the charter, he cannot be considered for re-election until October 2011. Other than being an eligible voter, there are no restrictions on eligible candidates. Steering Committee members must commit to attending two out of every three annual NANOG meetings per the charter (6.2.6). A good candidate will have experience with Internet engineering, operations, and governance organizations as well as the principles and practices which guide them. Consensus organizing, leadership, outreach and communication skills are prized. NANOG Program Committee The Program Committee is a group of sixteen individuals from the NANOG community who together are responsible for the solicitation and selection of material for NANOG meeting Programs. A new Program Committee will be selected by the Steering Committee after the election in October. Eight positions are to be filled. The currently-serving Program Committee members whose terms are expiring are Nina Bargisen, Tom Daly, Brian Deardorff, Igor Gashinsky, Mike Hughes, David Meyer, Tom Scholl and Richard Steenbergen. Furthermore, Igor, Mike and Richard have all served two consecutive terms so per the charter, they cannot be considered for another Program Committee appointment until October 2011. Per the NANOG charter (6.2.1), eligible candidates are individuals who have attended at least one NANOG meeting in the past 12 months (one or more of NANOG 48, NANOG 49 or NANOG 50). Broad technical knowledge of Internet operations and familiarity with NANOG meetings are useful attributes. Having constructive opinions and ideas about how NANOG meetings might be improved is of high value. NANOG Communications Committee The Communications Committee is a group of five individuals from the NANOG community who together are responsible for the administration and moderation of the NANOG mailing lists. A new Communications Committee will be selected by the Steering Committee after the election in October. Two positions are to be filled. The currently-serving Communications Committee members whose terms are expiring are Randy Epstein and Tim Yocum. The main NANOG mailing list serves an important role in the community by providing a day-to-day forum for network operators. Participating in the CC gives you the opportunity to make a noticeable contribution. The CC is covered under section 7.1.2 of the NANOG charter. Why? If you care about NANOG as a set of fora and think you would like to take a turn at volunteering your time to help make it better, please consider either volunteering yourself or nominating someone else. Also, as NANOG evolves into a fully self-governed organization, these committees will play an increasingly important role in our success. By joining now, you can be an integral part of the process. For more information about the role of any Committee, or to find out more about what's involved in being a Committee member, please do consult the current NANOG charter or contact someone who is already serving and ask them directly. Thanks, Steve Feldman on behalf of the NANOG Steering Committee _______________________________________________ NANOG-announce mailing list NANOG-announce(a)nanog.org https://mailman.nanog.org/mailman/listinfo/nanog-announce
