Probleme mit Resolving nic.ch
by Klaus Ethgen 06 Sep '10

06 Sep '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, ich habe seit einiger Zeit auf allen meinen Nameservern Probleme, die komplette Zone nic.ch zu resolven. Diese Probleme beschränken sich ausschließlich auf nic.ch, mir ist keine andere Zone aufgefallen, die Probleme macht. Vermutlich treten die Probleme seit September 2009, also mit Umstellung auf DNSSec, auf. (Ich kann es leider nicht hundertprozent genau datieren.) Nach einigen Debuggingschritten bin ich etwas ratlos. Meine Firewall läßt in beiden Fällen (bei jeweils auch einem komplett anderen Provider) alles durch, was Port 53 anbelangt. Auch ein Ausschalten der Firewall bringt die selben ergebnisse. Auch ein Test mit verschiedenen anderen DNSSec-Domainen, auch solchen, die groß sind und somit fragmentiert werden (sollten, meine MTU ist 1500), stellen keine Probleme dar. Ein tcpdump zeigt aber recht schnell, daß von den UDP-Paketen von nic.ch immer nur das erste ankommt und alle weiteren nicht auf meinem Netzwerkinterface aufschlagen. Nun meine Frage: Hat oder hatte jemand von euch schon ähnliche Probleme und wie wurden sie behoben? Wenn es sich bei nic.ch um eine unwichtige Domain handeln würde, wäre es mir ja egal, aber sie ist ja doch nicht ganz so unwichtig.

Motorola ADSL Routers: DNS proxy bug?
by Benoit Panizzon 06 Sep '10

06 Sep '10

Hi all I seam to quite often stumble over this bug and wonder if the router is buggy or the client is buggy. Most Motorola ADSL/VDSL Routers which Swisscom sent to their customers for about the last two years or so, have a DNS proxy enabled by default. The dhcp clients get the IP address of the router as DNS. Now some resolvers (the linux glibc resolver at least), when resolving a hostname first ask for AAAA and when no RR and no error is returned, they ask for the A record. Now when a host is resolved that way via a Motorola DNS Proxy, the AAAA query does not result in: - No Error, no RR returned. But in - Error 0011 => No such Name. If the linux glibc receives Error 0011 it does not continue looking for an A record, but return 'Hostname not found' or similar immediately. Thus making hosts which have a valid IPv4 but first were asked for their AAAA address not reachable from linux. The workaround is to not use the DNS proxy on those routers. Windowses do not seam to have this problem, even with ipv6 enabled. So who is wrong? The linux glibc or the router? -Benoit-

Bluewin VDSL DHCP clue needed
by Aarno Aukia 16 Aug '10

16 Aug '10

Dear List, I am in need of a clueful bluewin tech, who can have a look at a bluewin VDSL DHCP issue we are seeing with multiple customer lines. After confusing about a dozen helpliners by phone using keywords like DHCP {discovery, request, reply, lease time} both my social-engineering-fu and patience are depleted. I'll share customer #s, syslogs, tcpdumps etc over private mail. Thanks and best regards, Aarno -- Aarno Aukia Atrila GmbH Switzerland

Reminder: DENOG 2 Call for Participation and Papers
by Arnold Nipper 12 Aug '10

12 Aug '10

DENOG 2 - Call for Participation and Papers The second meeting of the German Network Operators Group (DENOG) will be held in Frankfurt, Germany on the 4th of November 2010. We are pleased to hereby invite applications for presentations or lightning talks to be held at this event. General Information =================== DENOG is a community for professionals within Germany who are operating, designing or researching the Internet. It provides a technical forum where those working on, with and for the Internet can come together to solve problems with every aspect of their (net)work. The meeting is designed to provide an opportunity for the exchange of information among network operators, engineers, researchers and other professionals close to the network community. More information about DENOG (in German) can be found at http://www2.denog.de/ Information about the meeting will be published at http://www.denog.de/. Meeting Countdown ================= What When ------------------------------------------------------ Publication of Call for Papers May 11th, 2010 Deadline for all submissions September 15th, 2010 Beginning of Registration Period End of August, 2010 Publication of final programme End of September, 2010 Deadline for receipt of final slides October 24th, 2010 Meeting Day November 4th, 2010 Topics for Presentations/Talks ============================== The day will be divided into several sessions. The number and length of presentations per session is not fixed, although due to time constraints we would prefer the length of the presentations to be between 10 to 30 minutes. However proposals for longer/shorter presentations or presentations whose subject falls outside of the topics below are also welcome; please do not hesitate to submit them. Lightning Talks --------------- In addition to the topics mentioned below we will reserve slots for lightning talks, which consist of a few slides and will not last longer than 5 minutes. Lightning talks can be submitted until October 29th, with the deadline for submission of the corresponding slides being November 3rd. Topic #1: Power Efficiency in Networks --------------------------------------- For operators of networks and data centres of any size power efficiency has become more important. Servers and network gear with high power consumption are expensive because of high operating and cooling power costs; also in many places supplying more power into the location is no longer possible. How are you dealing with power problems in your environment? How do you efficiently cool a rack/a room/a datacenter? Can a migration to VoIP help you save power? Topic #2: Social Networks, Cloud Services and Information Security ------------------------------------------------------------------ Social Networks are an essential working tool for networkers and cloud services are also becoming increasingly popular. The security of your information and data in these networks is a crucial aspect which we want to discuss in this session. Topic #3: Network Neutrality ---------------------------- In the US, Network Neutrality has been a subject of controversy and debate. Is an ISP allowed to sell "Internet access" which only offers access to a subset of the whole Internet? Is an ISP allowed to prioritise video streams from Company A while imposing a higher delay to video streams from Company B? In Germany Network Neutrality is mainly an issue for mobile networks and not extensively discussed thus far. But what kind of problems will an upcoming debate on Network Neutrality bring to German ISPs and is there a good way to address these problems? Topic #4: Peering ------------------ Everything about your peering experience. Why are you doing it? How are you doing it? Have you written any useful tools which others might find interesting? Topic #5: ISP BOF ----------------- "All things ISP". From Network/SLA Management (for or against it), abuse handling and log systems to data centre layout and planning (including power and cooling), everything that is interesting to you as an ISP can be presented or discussed within this topic. Language of Slides and Talks ============================ To appeal to an international audience we ask you to produce your slides in English, but the spoken language of the presentation itself can be either German or English. Submission Guidelines ===================== All submissions must have a strong technical bias and must not be solely promotional for your employer. Please remember that your presentations should be suitable for a target audience of technicians from varied backgrounds, working for companies whose sizes may vary considerably. To submit a proposal for a presentation, we request that you provide the following information as plain text or PDF format to <denog-pc(a)denog.de>: * the name of the presenter (and if applicable your affiliation) * a working email address * the name and number of the topic which will contain the presentation * the title of the presentation * its expected length (in minutes) * the preferred spoken language for the presentation * a short abstract of the presentation (not more than 200 words) We also welcome suggestions for specific presentations which you feel would be valuable to the DENOG community. Please be aware that your presentation will be published on the DENOG website after the event.
