Gentlefolks, Below you'll find the Draft minutes of our meetings at RIPE-47. They have been reviewed by the chairs already. Please send your comments to the list or directly to the list. Thanks to our scribes, Timur Bakeyev and Arno Meulenkamp (in alphpabetical order of last name) and the webmaster at ripe.net whois is Bcc'd on this so he/she can place the minutes on the ripe web site. Note that there is also an action item to work on: Formulate a charter/workingplan for the new combined group. I will try to make a rough proposal, although I wouldn't mind if somebody else would do that instead. I don't know who put the charter up at http://www.ripe.net/ripe/wg/dns/index.html and assume it is only a placeholder for the real one to come. Does anybody has an old version of the charter of as well as the DNR forum and the DNS-wg oldstyle lying around? These might be a good start for a new charter. Anyway, enjoy, jaap ---- DRAFT minutes, cut here ------ RIPE 47 Meeting DNS Working Group and DNR Forum Agenda Date: Tuesday 27 January 2004 Time: 16.00 - 17.30 Location: Grand Ballroom A. Administrative matters: - Scribe: Arno Meulenkamp - Blue sheets - Agenda bashing Jaap: (1) The talk about WSIS will be drop, because it is also on the agenda of the Plenray; will be replaced by a report over the "Last Call Workshop at Ripe NCC" about DNSSEC (2) The talk about the SSAC DNSS document will not be seperate agenda item, but will be covered during the "News from ICANN" item (3) Jakob Schlyter couldn't come. - Minutes Ripe 46 (http://www.ripe.net/ripe/wg/dns/r46-minutes.html) B. To merge or not to merge Heads up for discussion at end of Agenda (Chairs). Not a lot of discussion on the mailing list, so no decision can be made currently, discussion needs to be continued. C. Status reports Centr Report (Kim Davies) [5-10 minutes] Kim Davies presented the report. Daniel Karrenberg: Freedom of information? Kim: Perhaps I should have said data protection laws provreg (Jaap [1 min]) Jaap Akkerhuis: We were waiting on the IANA XML registry. This is just recentky established, the XML RFC is published. So now the rfc-editor can continue dnsext Suzanne Woolf dnsop Suzanne Woolf Suzanne Woolf presented an overview of what happened recently in the WGs enum Patrick Faltstrom Patrick Faltstrom: the RFC has been approved, the RFC editor will look at it, it is in the queue right now Jaap: 3 documents? Patrick Faltstrom: Yes, 3 documents Jim Reid: what's the estimate before the RFC editor will look at it? Patrick Faltstrom: hard to say, we are #5 on the list. Could be up to 3 months from now. sshfp Jakob Schlyter Jakob couldn't make it crisp Lesley/Anthony [By proxy, 5 min, Jaap] They also couldn't make it, but they did send slides, which Jaap presented. ICANN/IANA news [10 min] presented by Doug Barton No slides. DNS Infrastructure Recommendation Of the Security and Stability Advisory Committee. ICANN report, which can be found here: http://icann.org/committees/security/dns-recommendation-01nov03.htm AAAA records in the root, Daniel Karrenberg There was some research to see what happens with more glue in the root, this to accomodate IPv6 addresses in the zone file. There might be a technical problem. Doug: There are concerns over changing the root zone. We're trying to work with all parties involved. Jim Reid: is there look into what might happen when AAAA records are added, because IPv6 traffic might cause other operational things Doug: this is looked at. Iljitsch van Beinum: This is looked at for tld's and root zone? Daniel: yes Daniel: what is the timeline? Doug: the RSAC recommendation (see link) needs to be formally presented to the ICANN board. And it also needs to be published publicly and we need to see what the feedback is. Suzanne Woolf: is the IANA looking at how the technical recommendation would be operationally implemented? Doug: yes, when we present the plan officially, we also want to add a recommendation. D. Registrar/Registry News News from RIPE NCC Update on dnsmon: Going beta [5 min], Daniel Karrenberg It is now Beta, still on development machines, documentation is much improved, soon completely ready. Changes in RDNS [25 min], Olaf Kolkman (or replacement) Olaf presented the project. Andre: does the mnt-domains in inetnum override the mnt-by in the domain object? Olaf: no, it only controls the creation of the object, the mnt-by in the domain object then takes care of protecting the object. Peter Koch: you said this will not save the lameness problem,why not, what are you going to do? Olaf: it is quite different thing, we're not trying to solve too many problems at the same time. We check when delegations are created, that will not change. Lameness might come later. Peter: Old domain objects could be fed through the system, do you have any number of lame delegations or other DNS problems? Olaf: not currently Jim Reid: with regard to lameness, the working group should look at this and maybe make a definition of lameness after which we can map the situation (with the help of the RIPE NCC, perhaps) Jim Reid: as chair: does this working group approve of this project, do we think we need to say something about this (as it is internal housekeeping to some extent)? Jaap Akkerhuis: time flies. Let's postpone the other registry points to the other slots. Date: Thursday 29 January 2004 Time: 09.00 - 12.30 Location: St. Johns II Chair: Jaap Akkerhuis, Jim Reid Scribe: Timur Bakeyev, RIPE NCC Thanks to our scribe. Introduction. Short description of the Tuesday session. Scribe is presented to the public. News from CZ, Ing Tomas Marsalek [15 min] covers: new registry model enum idn file:DNS/cznic.ppt A nice story about cybersquatter who claimed 10.000$ for the domain from one of the bank groups but was sued and charged for half of this sum :> No questions were asked. News from PL, Andrzej Bartosiewicz [20 min] covers: idn monitoring internal systems ISO 9001 certification archiving blessed by Polish Certification Office file:DNS/RIPE47_DNS_PL.ppt Due to the shortage of time the introduction slides were skipped. Andrzej described the process of deployment of IDN for .pl domain. The policy is: First come - first served. In first few days a peak of the interest to the IDN was noticed(1600 registrations), now the average number of new domains registrations is around 20 per week. EPP for ENUM part of the presentation was skipped; it was already presented during the enum BOF. The overview of the process of monitoring DNS servers and services was done by Slawomir Gruca. In the past they had several conflicts, then the customer claimed, that the given domain wasn't accessible at certain date/time. Since then they start to use zone signing service via SigNet.pl as a proof that domain zone did exist in the particular time in this state. Q: In the slides it's mentioned, that the 'crucial domain list' is used to monitor the possible harmful changes to the DNS. Who did compile this list? A: This is the list of the most popular domains, which was provided by the 3-d parity. It's assumed that domains from that list are the best target for frauge. The changes in nameservers layout of these domains are also verified by a human. Q: Do you provide monitoring from the end user point? A: That's in the plans of the company. Q(Bruce): What is actually tracked for the domains from the 'crucial list'? A: List is monitored by script, which checks changes in the name servers structure and delegation information. E. Other news News from ISC, Joao Damas [20 min] covers: Bind road map OARG file:DNS/dns-wg-ripe47.ppt ISC is dead! Long life ISC! ISC had changed their name from Internet Software Consortium to the Internet System Consortium. New incidental respond group is created - Operations, Analysis and Research Center(OARC). http://oarc.isc.org. F-root server in Paris, Moscow, Dubai, Beijing, Taipei, Singapore. New Bind forum(and DHCP in future). Bind will remain free! Two parallel versions were released - Bind 8.4.4 and Bind 9.2.3. Bind8 is in a maintainace phase - only security fixes. Focus is on Bind9 and improving it's performance and support of DNSSEC. Q: It is said, that F-root server in Paris is IPv6 enabled. Is this information publically available and how to get it? A: You need to ask sysadmins of their provider. Q: Is this some kind of a secret then? A: No, it just means that this setup is still considered under trial and still in development. Q: Whom should I contact then? A: Tiscali.fr. Q(humorous): Can you, please, stop releasing Bind8? Version 9 is so cool and existence of the persistently updating Bind8 keeps people from switching to version 9. A: For Bind8 only bug fixes are done. All new features are added to the Bind9. Comment(Daniel): Bind8 is buggy, that's the reason for so often releases. Also, it still outperforms Bind9. Comment(Joao): One nice feature Bind9 has - an automated update of the hints file(with the list of root servers). With the upcoming change of the IP of the B-root server tomorrow(30 Jan 2003) it makes it very neat feature(Bind8 users need eventually to download a new version of hint file by themselves). Q: Regarding IPv6 support. http://www.root-servers.org/ lists the IPv6 addresses of some of the root servers. Would it be possible to ship hints file which will include IPv6 addresses of these servers as well? A: Speaking about web page - it's a good idea. Hints file... Well, we'll see :) Comment: B-root would be available on the old address for quite reasonable amount of time(2 years). Q: For Bind8 users - the change of the B-root IP address isn't an emergency? A: Completely not, but eventually this file should be replaced. DNSSEC workshop, Joao Damas [20 min] file:DNS/lcws.ppt The workshop was done in cooperation with NLnet Labs and RIPE NCC. The goal was to check interoperability of two implementations of the DNSSEC - one is in the beta version of Bind9.4 and another in NSD2.0. The results of workshop did prove, that this two versions can interoperate, but also a lot of updates and remarks were done to the DNSSEC draft and send back to IETF. Q: How long will it take before thre is a standard? A: Workshop helped a lot to spot the issues in the current draft of the standard. It will take a while, before all of them will be fixed in the document. At minimum, 2 more months... F. Tools Fingerprint DNS-servers, Roy Arends [20 min] file:DNS/Fingerprinting DNS.ppt The goal of survey was troubleshooting, statistic information on distribution of different version of DNS software. Different versions of different name servers were run in the test environment to collect an authentic fingerprint of them. Still looking for pre BSD4.3-tahoe bind implementation. Comment(Daniel): We have contacts with people who are still own necessary hardware and software. Still, no available CISCO DNS implementation(?) Olaf's DNS calculator was mentioned as on of the amazing examples of Perl based DNS servers. Survey also helped in spotting bug in the QR bit handling of one of the DNS server implementations, which could lead to the DoS attack. Fixed! Software is available at: http://www.rfc.se/fpdns/ Note from the audience: PowerDNS is mentioned twice on the slide! Q(Jim Reid): What is the distribution of the DNS software according to the survey? A: Out of 50.000 queried servers nearly half do run Bind9, a quarter - Bind8 and most of the rest are Windows DNS. But if to count by number of zones, supported by server, then Bind8 is the winer :() NSD & DNSSEC, NLnetlabs, Erik Rozendaal [5 min] file:DNS/erik-rozendaal.tar.gz Short introduction to NDS - simple, high performing name server for authoritative zones. Q(Joao): What kind of traffic is shown on the graphs? Does it reflect real life scenario, when unreplied(dropped) queries actually create additional queries, coming from the client side, artificially increasing load? A: Have no idea... PowerDNS, Bert Hubert [30 min] file:DNS/powerdns.pdf Written in C++, multithreaded DNS server. Multiple backends. No DJB-isms :)) Had a 0x1FFFFFFF bug in the code :) Q: Is TSIG supported? A: I have it in my plans. G. Experiences DNSSEC in .NL; preliminary results (Miek Gieben, NLnetlabs) [20 min] file:DNS/miek.tgz Q: What does phrase in the slides 'automated key compromise' actually mean :)? A: The zone dropped immediately. IDN Implementations in Europe, Kim Davies [40 minutes] file:DNS/ripe47-dn-idneurope.pdf Q: End user problem: How can I type in Chinese, let's say domain name? A: Have no idea, the main application for IDN is local usage within this language speaking country/community. Q: Any plans for having IDN for TLDs? A: Not yet. Q: What browsers are already support IDN out of the box? A: Two are known at the moment - Mozilla and Opera. H. To merge or not to merge (continued) 5 minutes past the lunch break. Jim shouts: Shall we merge or not? Audience screams: YES! Everyone runs for the lunch :) Action Item: Charter for the new group. $Id: minutes,v 1.2 2004/02/19 20:31:07 jaap Exp jaap $
