HSRP vs VRRP for IPv6 on IOS-XE - rekindling an old flame
by -Hammer- 31 Jan '13

31 Jan '13

A while back I brought up a discussion about IPv6 and I mentioned having some HSRP issues. Not end of the world, just adjusting to IPv6. Several folks went offline to tell me that I should dump "legacy" HSRP and go to VRRP. While I never did find anyone who could explain how HSRP is a sunset feature in IOS, I did agree with a few folks to look into VRRP for IPv6. Well I'm just now getting around to it and there is literally nothing out there. I found a few older articles implying that it's not there yet and of course I found the usual docs about RAs and SLAC and whatnot. But nothing recent. So, for those who criticized me previously about using HSRP (or anyone else) instead of VRRP, do you have VRRP up and running on Cisco IOS-XE and if so how? Can anyone provide a link or a document explaining how this is accomplished? Sample configs? Usually if you can't find it on Google or CCO it's not promising. I'm also reaching out to our AS team for guidance on the subject. PS: I'm not taunting here. It's just that several folks made the effort to go offline with me and tell me how wrong I was with HSRP and that I need to progress to VRRP and I can't find a single doc on the subject now that I look. Were these folks mistaken or am I missing something? Any help would be appreciated. -- -Hammer- "I was a normal American nerd" -Jack Herer

IP Address Management IPAM software for small ISP
by Eric A Louie 24 Jan '13

24 Jan '13

I'm looking for IPAM solutions for a small regional wireless ISP. There are 4 Tier 2 personnel and 2 NOC technicians who would be using the tool, and a small staff of engineers. They have regionalized IP addresses so blocks are local, but there are subnets that are global. don't care if it's a linux or windows solution. Need to be able to migrate from FreeIPdb (yes, I know, it's a dinosaur) We're not dealing with a lot now, but the potential for growth is pretty high. What are you using and how is it working for you? Much appreciated, Eric

State of the RING 2012
by Job Snijders 15 Jan '13

15 Jan '13

Hi, Here is the yearly update regarding the NLNOG RING project, this year's update includes some links to tools that might be of interest to the broader community. More information about the RING can be found here: https://ring.nlnog.net/ Kind regards, Job ============================================================ State of the NLNOG RING 2012 A yearly newsletter about the best debugging project ever Edition 2, 28 Dec 2012 ============================================================ Contents ============================================================ 1. Introduction: growth 2. New services 4. Into the future! 5. Testimonials & conference exposure 6. Closing notes ============================================================ 1. Introduction: growth ============================================================ Today, 28th of december 2012, the RING turns 2 years old! The project's origins can be traced back to the following line on IRC (translated): [28 Dec 2010/10:26 CET - #NLNOG] "hey, maybe we should create a #nlnog test platform" And now here we are, 2 years later: 188 machines provided by 165 organisations in 39 countries. Compared to 2011 we have more than doubled in size! From our usage statistics we gather that 65% of organisations actively makes use of the RING through SSH. Other statistics gathered from our code repositories: - 1111 commits were made (doubled since last year!) - Most code commits happened, again, on Tuesdays - Lines of code: 20267 insertions(+), 5774 deletions(-) We could not have sustained this level of growth without the continuing support of our infrastructure sponsors and the 2012 fundraiser contributors: XS4ALL, Amazon Web Services, Leaseweb, Atrato IP Networks, Gossamer Threads, BIT, PCextreme, SoftLayer, Snijders IT, Solido Hosting, Duocast, A2B Internet, Nedzone, Tetaneutral, LCHost, Previder, Triple IT and eBay Classifieds Group. A full overview of all supporters can be found here: https://ring.nlnog.net/patrons/ ============================================================ 2. New services ============================================================ AMP (Active Measurement Project): --------------------------------- One of the biggest changes this year was moving from a distributed master/slave smokeping setup to something much better: AMP. The AMP software performs measurements from every RING node to every other RING node, and reports the results to central collectors which in turn feed a web interface. AMP as a tool offers us insight in end-to-end MTU, jitter, latency, packetloss and historic traceroutes both for IPv4 and IPv6 between all RING nodes. URL: http://amp.ring.nlnog.net/ BGP Looking glass: ------------------ Due to popular request we set up a BGP looking glass, which currently receives full IPv4 and IPv6 tables from 35+ participants. The LG uses the BIRD BGP daemon with a web interface written by one of the RING participants! We currently are exploring if we can use the collected data for a monitoring and alerting system to help participants gain insight in prefix visibility and, for instance hijack events. Stay tuned! URL: http://lg.ring.nlnog.net/ IRR/RPLS services: ------------------ Although the IRR system and RPSL have been around for a long time, there still is a lot of room for improvement in terms of performance, ease of use and standardised methods and tools. We believe that the RING community can make a difference in the popularity of proper filtering. One of the first things we offer (in beta) is a web service to expand RPSL object such as AS-SET, AUTNUM and RS-SETs and expose the data in JSON. URL: http://irr.ring.nlnog.net/ ============================================================ 3. Into the future! ============================================================ In 2013 we will continue to automate as many aspects of the RING as possible. But more importantly, the RING has to become the best swiss army knife a network engineer can imagine so we will focus on usability, more advanced tools and security. We are making a lot of progress towards publication of all kinds of RING related information in an easy accessible database, we imagine this will accelerate the development of a new generation of tools! We also started talks with other debugging projects such as RIPE Atlas to explore if cooperation and exchange of information can further such projects. As the RING is a community effort, we can only become more valuable to our members by help from the community. We need you for new creative ideas, high quality code, and of course more RING nodes. If you can help out in our efforts, don't hesitate to contact us! ============================================================ 4. Testimonials & Exposure ============================================================ Two debugging cases have been documented, where the RING proved to be of vital importance when debugging an issue at hand. Route leak: ----------- A root-cause analysis based on historic data collected by the RING. URL: https://ring.nlnog.net/news/root-cause-analysis-using-amp/ The IPv4 address that ended with .255: -------------------------------------- How the variety in RING nodes helped locate an ancient, dysfunctional ACL. URL: https://ring.nlnog.net/news/ring-success-the-ipv4-255-problem/ Conference exposure: -------------------- Various RING participants have spoken at Internet oriented conferences around the world. The following meetings made a presentation slot available to the RING: eduPERT, LINX79, MENOG11, NANOG56 and RIPE65. All of these presentations have helped the RING grow, as in the days after such a presentation we saw a spike in RING participant applications. If you want to present about the RING at a meeting in your region or local operator community, please contact us. We have great slides available for this purpose! ============================================================ 5. Closing notes ============================================================ We conclude this newsletter by saying to you, the participants, THANK YOU! Without the continued support from lots of participants the RING would not be where it is today. We are proud to be playing a small role in making the Internet an easier thing to debug and research. Again, thank you! Kind regards, Job Snijders Martin Pels Peter van Dijk Edwin Hermans ringthing

RE: [j-nsp] Krt queue issues

Look into Static route retain. Should keep the route in the forwarding table. >From Jniper site <<< Route Retention By default, static routes are not retained in the forwarding table when the routing process shuts down. When the routing process starts up again, any routes configured as static routes must be added to the forwarding table again. To avoid this latency, routes can be flagged as retain, so that they are kept in the forwarding table even after the routing process shuts down. Retention ensures that the routes are always in the forwarding table, even immediately after a system reboot. >>> Thanks, Jensen Tyler Sr Engineering Manager Fiberutilities Group, LLC -----Original Message----- From: juniper-nsp-bounces(a)puck.nether.net [mailto:juniper-nsp-bounces@puck.nether.net] On Behalf Of Benny Amorsen Sent: Wednesday, October 03, 2012 8:32 AM To: Jared Mauch Cc: Saku Ytti; juniper-nsp(a)puck.nether.net Subject: Re: [j-nsp] Krt queue issues Jared Mauch <jared(a)puck.nether.net> writes: > As far as the fallback 'default' route, if you are purchasing transit > from someone, you could consider a last-resort default pointed at > them.

If the default has to wait at boot in the krt-queue behind the 300k+ Internet-routes, I have not really gained anything... I suppose it is likely that a static default would be installed before the BGP sessions even come up. /Benny _______________________________________________ juniper-nsp mailing list juniper-nsp(a)puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

Re: Gmail and SSL

Your assertion that using "bought" certificates provides any security benefit whatsoever assumes facts not in evidence. Given recent failures in this space I would posit that the requirement to use certificates purchased from entities "under the thumb" of government control, clearly motivated only by profit, and with highly questionable moral and ethical standards represents a huge increase in risk of passive attack and confidentiality failure where such rosk did not previously exist.

GeekTools Whois Proxy and RIPE/RIPE-NCC
by Rodney Joffe 01 Jan '13

01 Jan '13

NANOG and ARIN Friends, 14 Years ago, at the suggestion of Jon Postel and some of the early participants in NANOG, we developed the GeekTools Whois proxy to make it easier for *us* - network security and abuse techs - to deal with the expanding number of gtlds and registrars and the varied whois servers that were appearing. The service had both a CLI and web interface. The service also led directly to the creation of whois-servers.net, which now seems to be part of a number of *nix distributions. The service has been up for 14 years, and over that time we have fulfilled the requirements of all of the whois server operators in regards to minimizing and stopping abuse of the GT whois proxy by domain scrapers, spammers, etc, while enabling the security folks to do their jobs. In some cases we have even written code to pass the ip address of the requestor to the whois server registry operator when they wanted to manage quota's directly. We think we have a really good relationship with all of the whois server operators, and I think we provide a useful service to the community, and is widely used. And in 14 years we have never been tarred as an enabler of abuse of "the whois" system. There has obviously never been any kind of charge or fee for using the proxy, or any of the other tools on GeekTools. In about 2002 we started placing a banner ad on the web interface page to offset some of the costs for the bandwidth that the proxy consumes. An average of about $70 a month for over the last 10 years. Actual bandwidth costs are higher than that of course, but it was a thought in 2002 that we had frankly forgotten about until recently. Two weeks ago RIPE-NCC, who provide the whois data for IP addresses in the RIPE region, informed us that based on decisions by their members, as of January 1st 2013, tomorrow, they would no longer provide whois proxy query response services to GeekTools unless we ponied up $1,800 a year for RIPE membership. I don't work very well above layer 7. It is what it is. So I wanted to let you know that as of midnight tonight, apparently, you won't be able to use GeekTools for RIPE related queries. If you have automated scripts, and you are one of the users who has expanded access to GeekTools, you'll need to find an alternative for RIPE queries *today*. My guess is that you will be able to query RIPE directly, once you have worked out that the address space is within RIPE's assignments. I think its wrong to have to pay for whois data that is part of a community resource . So I won't do it.
