DDOS DNS Attack by Netgear Products caused by CNAME instead of A record?
by Benoit Panizzon 27 Jun '13

27 Jun '13

Heyo! Any others who are being affected? It looks like our customers Netgear routers (known ones: WNR3500Lv2, WNDR4500) are asking our DNS Server for the A record of: time-g.netgear.com or time- a.netgear.com Instead of an A record reply, they get a CNAME as answer with additional information the A record of that CNAME. That is what netgear has published on their DNS Servers. Those routers are not happy with that reply and just start sending several hundred requests per second for A time-g.netgear.com resulting in considerable load and traffic on our DNS caches. Some customers have already transfered 35GB of DNS traffic, only since today midnight. I have contacted netgear technical support. The issue is yet unknown to them. They got my pcap files to analyze :-) Any others observing that behaviour of netgear products? Any know remedies?

Filtering of NTP-access to swisstime.ethz.ch as of July 1st, 2013
by Wittmann Armin 25 Jun '13

25 Jun '13

*** German version below *** Dear NTP-Users of swisstime.ethz.ch After we changed the NTP use of swisstime.ethz.ch to ClosedAccess at the end of 2012 we tried contacting the main users of this service (via whois) for a six month period - unfortunately with minimal success. As of July 1st 2013 the time has come. SWITCH will block NTP-access at the border to Swiss NRENs so that commercial users and universities/ technical colleges (outside Swiss NRENs) will no longer be able to access swisstime.ethz.ch as a time server. This is for your information as well as for others who may be affected by this change.

Juli 2013 von ausserhalb des CH-NRENs Geschätzte ntp-User von swisstime.ethz.ch Nachdem wir Ende 2012 die ntp-Nutzung von swisstime.ethz.ch auf Closed Access reduziert haben, wurde während 6 Monaten versucht die Hauptnutzer des Services über whois-Einträge zu informieren, allerdings mit mässigem Erfolg. Per 1. Juli 2013 ist es nun soweit. SWITCH wird den ntp-Zugriff am Border zum Schweizer NREN blockieren, so dass kommerzielle Nutzer und Universitäten/Hochschulen ausserhalb des Schweizer NREN swisstime.ethz.ch als ntp-Server nicht mehr nutzen können.

Transparent 1Gig Ethernet over IP/Ethernet?
by chris burri 20 Jun '13

20 Jun '13

Hi all, I need to transparently (especially LACP frames) transport a gigabit ethernet link with at least 1500 MTU over either IP or Ethernet. Jumbo frames are enabled on the L2 transport backbone. While I need "full" (some encap overhead will be acceptable) GigE wire speed, encryption is unnecessary. Can anyone suggest a product -ideally some low-maintenance, high-reliability, perhaps ASIC-based hardware- that can do this?

dns oddity with cns7.bluewin.ch
by Ambauen Daniel 20 Jun '13

20 Jun '13

Hello list Does anybody know why cns7.bluewin.ch does answer one out of four specific queries with an mixed case DNS answer? ;; QUESTION SECTION: ;_autodiscover._tcp.id.ethz.ch. IN SRV ;; ANSWER SECTION: _autodiscover._tcp.id.ethz.ch. 43200 IN SRV 0 100 443 mail.ethz.ch. ;; ANSWER SECTION: _autodiscover._tcp.id.ethz.ch. 43200 IN SRV 0 100 443 mail.EThZ.CH. The Outlook mail client is treating the DNS answers case sensitive so mail.ethz.ch and mail.EThZ.CH are not the same. Every time the mail client discovers a different "mail.ethz.ch" the user has to accept the new mail.etHz.cH server. >From my point of view the use of Bit 0x20 in DNS Labels should happen between caching and authoritative name servers. http://tools.ietf.org/html/draft-vixie-dnsext-dns0x20-00 Is my point of view wrong?

sflow proxy/multiplexer
by Julian Rutz 18 Jun '13

18 Jun '13

Hi there, Maybe some of you folks can give me a hint on this... I do have a linux box which is receiving sflow data from routers/switches/etc. I want this box to forward the sflow data to two or three other hosts. So I am looking for a "decent" sflow proxy/multiplexer. Any suggestions are welcome - preferably opensource :) Thanks in advance. Cheers, Julian
