telnet into a netgear switch?
by David Birdsong 25 Nov '13

25 Nov '13

Hey all, last night while at the datacenter I was in a pinch to extend a rack's LAN. I compromised and ran out to the local Fry's to buy whatever switch I could find so as to allow some configuration to happen while we wait for the real network gear to show up. I left before confirming I could access the switch remotely; it was very late and I was pretty groggy and hey, any network gear has to be telnet'table this day and age. Of course I was mostly wrong. The switch expects some signed payload before allowing a telnet through. I found this: https://code.google.com/p/netgear-telnetenable/...but I'm having a hell of a time getting anything to respond. The most confounding part is the switch doesn't respond to a single SYN packet on low ports. I'm scanning all the ports now, but if nothing shows up, I'm not sure what a payload is good for if the switch doesn't ACK a single SYN. I'm curious if anybody's got any tips besides not using Netgear in the datacenter. I have the MAC, I've IP'd it via DHCP, and the model number: JGS524E and I can power cycle the switch as much as needed. P.S. long time listener, first time caller. i'm more of a sysadmin dangerously standing in for a proper network person.

Re: AT&T UVERSE Native IPv6, a HOWTO
by Brzozowski, John 25 Nov '13

25 Nov '13

Andrew, Question is this native or 6rd? According to my ARIN WHOIS query it looks like 6rd. Definitely great news that you were able to acquire IPv6. John Date: Sat, 23 Nov 2013 01:22:02 -0500 From: Andrew D Kirch <trelane(a)trelane.net> To: nanog(a)nanog.org Subject: AT&T UVERSE Native IPv6, a HOWTO Message-ID: <5290498A.6040405(a)trelane.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Special thanks to Alexander from AT&T's "Tier-2" dept, though my suspicion is that that is not where he works, as he seems exceptionally clueful. Additional thanks to Owen DeLong who finally got me off my ass to actually do this, I'll see you in the sky! Ok, is this core routing? not really, but it's nice to see a major clue injection over at AT&T Uverse. I'm using this to document the MASSIVE bureaucratic PITA which is getting native IPv6 on uverse. You'll start from the default service on a 2wire "modem" (for values of modem that equate to profanity). If you have the Motorola NVG589, count yourself lucky and skip most of these steps. Abandon all hope ye who enter here.... Step 1: contact AT&T Uverse support and complain that you need IPv6 (because we all need it, I in fact do for work). Step 2: general confusion as the level 1 droid doesn't know what IPv6 is, politely request to be transferred to tier 2 step 3: you will be told that tier 2 is a paid service, invoke the almighty FCC and ask to speak with a supervisor, expect a long hold here. step 4: you arrive at tier 2, mention that IPv6 won't work on your 2wire and that AT&T has broken your protocol 41 tunnel with <insert tunnel broker here, usually HE> step 5: you'll need to get your 2wire replaced with a Motorola NVG589. Again you will be threatened with a cost to upgrade, mine was waived due to the work requirement. I'd guess some additional complaining and escalation will get this fee waived. My recollection was it was $100. The new modem is good news for quite a few reasons, the 2wire sucks, the Motorola sucks significantly less, and has a built in battery backup, but mine lacked the battery. step 6: you'll receive the motorola by mail, or have a tech install it, they actually had a tech in my area and I had an AT&T tech at my door in less than 20 minutes from when I got off the phone with tier-2 (I about died from the shock). step 7: configure the motorola (192.168.1.254) for passthrough, DHCPS-dynamic, disable the firewall, the "advanced" firewall, hpna, wireless, etc. Step 8: reboot to push the public IP to your real router. step 9: head over to the Motorola's home network tab, and in the status window you'll see: IPv6 Status Available Global IPv6 Address 2602:306:cddd:xxxx::1/64 Link-local IPv6 Address fe80::923e:abff:xxxx:7e40 Router Advertisement Prefix 2602:306:cddd:xxxx::/64 IPV6 Delegated LAN Prefix 2602:306:cddd:xxxx:: 2602:306:cddd:xxxx:: In reality additional poking leads me to believe AT&T gives you a rather generous /60, but how to use it? step 10: set up dhcpv6, example for mikrotik follows (but should be easily convertible to nearly any router): /ipv6> export # dec/31/2001 20:26:03 by RouterOS 6.6 # software id = 5F2Y-X73L # /ipv6 address add address=2602:306:cddd:xxxx::1 from-pool=AT&T interface=bridge1 /ipv6 dhcp-client add add-default-route=yes interface=ether10 pool-name=AT&T I hope that this is of help to someone.

Policy-based routing is evil? Discuss.
by William Waites 25 Nov '13

25 Nov '13

I'm having a discussion with a small network in a part of the world where bandwidth is scarce and multiple DSL lines are often used for upstream links. The topic is policy-based routing, which is being described as "load balancing" where end-user traffic is assigned to a line according to source address. In my opinion the main problems with this are: - It's brittle, when a line fails, traffic doesn't re-route - None of the usual debugging tools work properly - Adding a new user is complicated because it has to be done in (at least) two places But I'm having a distinct lack of success locating rants and diatribes or even well-reasoned articles supporting this opinion. Am I out to lunch? -w -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

NAT64 and matching identities
by Justin M. Streiner 23 Nov '13

23 Nov '13

It's looking more and more like NAT64 will be in our future. One of the valid concerns for NAT64 - much like NAT44 - is being able to determine the identity of a given user through the NAT at a given point in time. How feasible this is depends on how robust/scalable $XYZ's translation logging capabilities are, and possibly how easily that data can be matched against a source of identify information, such as RADIUS accounting logs, DHCP lease logs, etc. Other IPv6 transition mechanisms appear to be no less thorny than NAT64 for a variety of reasons. I'm curious to see how others are planning to tackle (or already have tacked) this issue. Discussing vendor-specific solutions is fine, but I think keeping things as platform/vendor agnostic as possible for the time being would allow this thread to be more beneficial to a wider audience. The floor is open... jms

prefix filtering per IRR - practices
by Frank Habicht 22 Nov '13

22 Nov '13

Hi, I have a question regarding what's the most common practice [1] for transit ASs to filter prefixes from their BGP customers when using IRR data. (which of course everyone does...) Would many/most/all/none : a) accept only the prefixes listed in route objects or b) accept these and anything "upto /24" (or "le 24") I was hoping / assuming the latter but I start getting a different impression. Yep, and apart from the current status, the tendency would be of interest. Thanks, Frank [1] after "my network, my rules"

Super Computer 13: GPUs would make terrific network monitors

http://www.networkworld.com/news/2013/112113-sc13-gpus-would-make-terrific-… Super Computer 13: GPUs would make terrific network monitors An off-the-shelf Nvidia GPU is able to easily capture all the traffic of a 10Gbps network, Fermilab research finds By Joab Jackson, IDG News Service November 21, 2013 02:50 PM ET Sponsored by: IDG News Service - A network researcher at the U.S. Department of Energy's Fermi National Accelerator Laboratory has found a potential new use for graphics processing units -- capturing data about network traffic in real time. GPU-based network monitors could be uniquely qualified to keep pace with all the traffic flowing through networks running at 10Gbps (gigabits per second) or more, said Fermilab's Wenji Wu. Wenji presented his work as part of a poster series of new research at the SC 2013 supercomputing conference this week in Denver. Network analysis tools face an extreme challenge in keeping up with all of the traffic of today's larger networks, he said. Adding to the strain, network administrators increasingly expect to inspect operational data in real-time, as it is happening. For processing, today's commercial monitoring appliances typically rely on either standard x86 processors or customer ASICs (application specific integrated circuits). Both architectures have their limitations, Wenji noted. CPUs don't have the memory bandwidth or the compute power to keep pace with the largest networks in real time. As a result, they can drop packets. ASICs can have sufficient memory bandwidth and compute power for the task, but their custom architecture is difficult, and expensive, to program. Nor do they offer the ability to split processing duties into parallel tasks, which is becoming increasingly necessary for watching high-speed networks. GPUs can offer all of these capabilities, Wenji said. They have "a great parallel execution model," he said, noting that they offer high memory bandwidth, easy programmability, and can split the packet capturing process across multiple cores. As their name implies, GPUs were originally designed to render graphics on computer screens. Their architectures, consisting of many processor cores working in tandem, also make them useful as general coprocessors good at inherently parallelizable tasks. In the latest Top500 ranking of the world's most powerful supercomputers, 38 machines used Nvidia GPUs to boost their output. The task of monitoring networks requires reading all the data packets as they cross the network, which "requires a lot of data parallelism," Wenji said. Wenji has built a prototype at Fermilab to demonstrate the feasibility of a GPU-based network monitor, using a Nvidia M2070 GPU and an off-the-shelf NIC (network interface card) to capture network traffic. The system could easily be expanded with additional GPUs, he said. In this setup, Wenji found that packet processing could be considerably accelerated through GPUs. Compared to a single core CPU-based network monitor, the GPU-based system was able to speed performance by as much as 17 times. Compared to a six core CPU, the speed up from using a GPU was threefold. Makers of commercial network appliances could use GPUs to boost their devices' line rates, as well as cut development costs by using pre-existing GPU programming models such as the Nvidia CUDA (Compute Unified Device Architecture) framework, Wenji said.

rogers.ca contact

Got an issue where rogers SWIPed blocks to my customer in prep for BGP peering and advertising, but at the last minute (right before we are to set it up) rogers is saying that we can't advertise it, as they advertise a larger block and that if we advertised it out our other provider it would be considered route hijacking and they would turn OFF the IPs though their network? Off-list is fine !
