06 Sep '16

Hi all I have a Huawei S6700 and each vlanif has a different mac. Is there any way so that all vlanifs have the same mac address? In brocades switches, for example, all ports have the same mac. Thanks. Josivan Barbosa

Last call for presentations and Draft programme for RIPE 73
by Benno Overeinder 06 Sep '16

06 Sep '16

Colleagues, A list of currently accepted RIPE 73 presentations is now published at: https://ripe73.ripe.net/programme/meeting-plan/draft-programme/ There are still few slots remaining for a final RIPE 73 programme and RIPE Programme Committee will accept new proposals until 25 September 2016. This is our last call for you to submit your proposals. You can find the CFP for RIPE 73 below, or at https://ripe73.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder RIPE PC Chair https://www.ripe.net/participate/meetings/ripe-meetings/pc -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 73 will take place from 24-28 October 2016 in Madrid, Spain. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 73. See the full descriptions of the different presentation formats, https://ripe73.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 25 September 2016. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Internet of Things (IoT) Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe73.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe73.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice---in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/

measuring web similarity from dual-stacked hosts
by Bajpai, Vaibhav 05 Sep '16

Dear NANOG, Measuring Web Similarity from Dual-stacked Hosts ------------------------------------------------ How similar are the webpages accessed over IPv6 to their IPv4 counterparts? – In situations where the content is dissimilar over IPv4 and IPv6, what factors contribute to the dissimilarity? To answer ^ we developed a tool (simweb) and deployed it on 80 geographically distributed dual-stacked SamKnows probes. A paper presenting results from the collected dataset got accepted recently. We just released the tool and the paper [a]. Thought to share it along. [a] http://goo.gl/sAsDcG Feedback most welcome! You may recall a presentation of this work at RIPE 72 [b]. [b] https://ripe72.ripe.net/archives/video/126 Abstract -------- We compare the similarity of webpages delivered over IPv4 and IPv6. Using the SamKnows web performance (webget) test, we implemented an extension (simweb) that allows us to measure the similarity of webpages. The simweb test measures against ALEXA top 100 dual-stacked websites from 80 SamKnows probes connected to dual-stacked networks representing 58 different ASes. Using a two months-long dataset we show that 14% of these dual-stacked websites exhibit a dissimilarity in the number of fetched webpage elements, with 94% of them exhibiting a dissimilarity in their size. We show that 6% of these websites announce AAAA entries in the DNS but no content is delivered over IPv6 when an HTTP request is made. We also noticed several cases where not all webpage elements (such as images, javascript and CSS) of a dual-stacked website are available over IPv6. We show that 27% of the dual-stacked websites have some fraction of webpage elements that fail over IPv6, with 9% of the websites having more than 50% webpage elements that fail over IPv6. We perform a causality analysis and also identify sources for these failing elements. We show that 12% of these websites have more than 50% webpage elements that belong to the same origin source and fail over IPv6. Failure rates are largely affected by DNS resolution error on images, javascript and CSS content delivered from both same-origin and cross-origin sources. These failures tend to cripple experience for users behind an IPv6-only network and a quantification of failure cases may help improve IPv6 adoption on the Internet. -- Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com Postdoctoral Researcher Jacobs University Bremen, Germany ===================================

Optical Wave Providers
by tim＠29lagrange.com 02 Sep '16

02 Sep '16

I have been looking at optical wave carriers for some long haul 1G/10G across the US. All to major cities and well known POP's. I am finding that there are not a lot of carriers who are offering wave services, usually just ethernet/MPLS. Particularly across the North west. Can someone shed some light on who some of the bigger carriers are and any challenges you have encountered with services like this? Who actually owns the fiber across the US? Thanks Tim

Software for tracking network related projects and activities
by Manuel Marín 02 Sep '16

02 Sep '16

Dear Nanog community We are currently using RT for tracking tasks related to network operations like BGP configuration change requests, circuit/ports activation, support tickets, etc, but when trying to track multiple activities that involve multiple departments, the RT (Request Tracker) system does not provide all the tools as a project/tasks management system. I was wondering if you can share what you use for tracking network related projects and activities. Thank you in advance Regards

( https://en.wikipedia.org/wiki/UNIVAC_Solid_State) Well this thing used a Mil-Spec 4K DRUM as its main memory. Now being mil-spec means the motor to spin the drum is 400 cycle AC. Where do you get 400 cycle AC in a 60 cycle world? Well you install a 60 cycle motor in the base of this monstrosity, and connect it via a fan belt to a 400 cycle AC generator that feeds the drum. We came in to class one day to warm the Univac up (it took about 30 minutes to fully power up) and noticed the machine being very quiet when we applied power. We eventually tracked it down to no power to the drum and it not spinning. And the reason the drum was not spinning? The fan belt had broken on the motor/generator set. :) Lucky, this was a Technical/Vocational high school, and we ran down to the auto repair class and bummed a new belt off them. :) ---- Then there was the time an engineer I worked with pressed the lamp test button on the huge engineering console display for a Burroughs B6700 room sized mainframe (like 3 foot by 3 foot bank of incandescent register and status displays) and the inrush caused the entire machine shut down.... but that's another story. ;) Chris Dunn Data Center Operations ServerCentral

Arbor Reports 540Gbps "Sustained" Attack
by Dennis B 01 Sep '16

01 Sep '16

https://www.arbornetworks.com/blog/asert/rio-olympics-take-gold-540gbsec-su… I've used SP Peakflow before and I have my opinions. With all the intelligence out there about DDoS attacks, DDoS attackers, DDoS tools and techniques this article leaves me with ton's of questions. IE: What industry was the attack target? Was it a single customer or multiple customers at the same time? What was the attack vector? Was it multi-vector? What was the duration of the 540Gbps attack? Did you actually block the attack or did you just report on it from your cloud signaling alliance aka cloud offering? Could you help explain if the peak of the attack lasted X minutes, Y hours, Z days? What was the attack targeted protocol? Was it TCP against TCP or UDP against UDP or UDP against TCP? I have to be honest, IDK if Arbor is attempting to claim the largest recorded DDoS attack in the world cup of DDoS attacks but the fact that your a local appliance shop. Selling to the global 100 and T1-3 ISPs - I'd hope for more than a marketing ploy to take the top attack vector. Thought I'd ask Nanog if they heard any whispers about this "white buffalo", which ISPs were Transiting the event, what course of actions were taken. Thanks!

See that big red button on the wall under the sign "Do Not Push This Button!".... DC 911 outage caused by contractor error http://wtop.com/dc/2016/08/dc-911-outage-caused-by-contractor-who-pulled-wr… WASHINGTON — D.C. is now operating two separate 911 centers after a power outage caused by human error left the nation’s capital without any emergency phone service for almost an hour on a busy weekend night. A contractor working Saturday night inadvertently pulled an emergency power shut off switch that cut electricity to the 911 phone system and a call routing system at the District’s Unified Communications Center, said the center’s Director Karima Holmes. “Unfortunately because it was human error we weren’t prepared for it,” Holmes said.
