Yeah, a visual route just showed my trace going to AUS and then Singapore. Hmm... You think Google is going to be pissed when they find out their site was being routed to Asia? Heads will roll...

My offices that use Sprint are having timeouts and major slowdowns to www.google.com Traceroute shows it going through reach.com and that is where the slowdown is occurring. See hop 11 below.

Name resolution in the .MIL domain
by Scott McGrath 19 Nov '04

19 Nov '04

Several of our researchers have pointed out that sites in the .MIL TLD are unreachable. Did a nslookup and got a interesting result > server ns.mit.edu Default Server: NOC-CUBE.mit.edu Address: 18.18.2.25 Aliases: ns.mit.edu > www.army.mil Server: NOC-CUBE.mit.edu Address: 18.18.2.25 Aliases: ns.mit.edu *** NOC-CUBE.mit.edu can't find www.army.mil: No response from server > www.navy.mil Server: NOC-CUBE.mit.edu Address: 18.18.2.25 Aliases: ns.mit.edu *** NOC-CUBE.mit.edu can't find www.navy.mil: No response from server I know it's MIT's nameserver just wanted to be sure the problem was not on our end. Send Harvard/MIT jokes to me offlist Back to the subject at hand is anyone else seeing the same issue with the .MIL domain Thanks in advance - Scott

Heathrow scanner experiences?
by Paul Wouters 19 Nov '04

19 Nov '04

[ It is a bit off topic, but I am looking for people who have travelled through Heathrow lately with the new x-ray scanner, and nanog people are generally engaged in a lot of traveling ] I was just pointed out to this article: http://www.theregister.co.uk/2004/11/18/blunkett_xray_blank/ It says: "To ask the Secretary of State for the Home Department what air kerma rate has been used to assess radiation doses associated with the use of the Rapiscan Secure 1000 apparatus." David Blunkett's (yes, him again, sorry about that) response was: "The information sought is not in the public domain." "This would mean that a security scanner would have to deliver 2,500 scans of an individual annually at 0.1 ÂµSv per scan in order to reach the US administrative control level of 0.25 mSv. For an airport security scanner, even operating at a rather higher level, you'd probably have to be living in it to achieve that kind of level." I went through Heathrow a few weeks ago, and was luckilly selected as a winner and destined to test these new Rapiscan boxes. I was informed it was an X-ray scanner, but with a very low dosage, the equivalent of being in an airplane for 11 minutes. Ofcourse only later did I realise that if these shots take 0.5 seconds, I was getting a dose 2*11*60= 1330 times the dose of the backgorund radiation of being in a plane. I wouldn't be suprised if those 11 minutes were per shot either. But at the time, I was more curious then worried. The machine looked like a big wall. I needed to stand in front of it, without jacket, arms and legs spread, torso turned. Two shots were made with me turned in both positions. A third shot was made when I was standing straight, exactly like a criminal. Legs slightly spread, arms up. I then asked to the officer if they were storing these scans, and what they actualy showed. He then offered me a look behind the scene (and screen). A second officer was there, looking at a monitor that still showed my third shot. I saw myself from behind, 'naked'. I was quite suprised that this technology could actually render me naked. I could see where I have body hair and where not. From a technological point of view quite an achievement. (There was a second scanner, but I am not sure if those were run by women, and whether they only picked women or not) The officer further told me this was meant to scan for objects on the body, and that the images were not stored. They did not ask me for my passport, so I don't think this information is cross checked or stored. I also read on an earlier news article that the person seeing the monitor cannot see the person in real life, which is meant to 'reduce' the privacy invasion. The person seeing you 'naked' never sees the real you. I forgot about the scanner and walked into the secure shopping mall, and checked for books. About five minutes after the scan, while I was not even thinking about the scanner anymore, I suddenly felt very nauseous all over. I then felt a sharp pain in my lower right abdomen which dissipated in the next minute. The nausea passed as well. I am a bit worried, and I did Google around, but found no other people reporting the same. I did not go back to the scanner, since I couldn't reach the insecure area anymore. I wondered about the pain. AFAIK there are no vital organs on the right side. The liver, spleen and 'alvleesklier' (?) should be more to the left or lower. The only thing on the right side is the end of your intestines. That made me think that in fact they might have used a higher dose or a more targeted scan to check deeper into my body for hidden drugs or explosives or whatever. I'd love to hear from anyone else who has gone through this scanner and what their experience was. Paul

Tricks reduce reliability and create unecessary dependancies. LNP was a regulatory issue post implementation of V4 so a trick was required.

Important IPv6 Policy Issue -- Your Input Requested
by Leo Bicknell 19 Nov '04

19 Nov '04

I would like to bring to the attention of Nanog an IPv6 policy issue that I think is slipping under the radar right now. The IETF IPv6 working group is considering two proposals right now for IPv6 "private networks". Think RFC-1918 type space, but redefined for the IPv6 world. Those two drafts can be found at: http://www.ietf.org/internet-drafts/draft-ietf-ipv6-unique-local-addr-07.txt http://www.ietf.org/internet-drafts/draft-ietf-ipv6-ula-central-00.txt These drafts came up in the ARIN meeting, and I posted my analysis of the problems with both at: http://www.arin.net/mailing_lists/ppml/2849.html I will post a very brief summary of my objections, for the first (unique-local): - I believe the math is wrong on the rate of collisions, primarily because it assumes in a large organization there is a central coordination function to pick and distribute these addresses. However, since the whole point of "unique local" addresses is that there need be no coordination, I can easily see a case where a large conglomerate (Ford, GE, whatever) coming together with another will have both sides bringing hundreds, if not thoundsands of prefixes to the table as each division or other subgroup picks their own. - I think the likelyhood people will use the suggested hash methods to pick addresses is extremely low. People will either pick "human friendly" (1, 2, 3, 4, etc) or treat the space more like CIDR (where there is central delegation), both of which move the likelyhood of collision to near 1. In the end I think we need 1918 style space, and that it should simply be set aside as a large block and expected to never be useful in the context of other organizations, just like 1918 space is today. The second proposal (ula-central) is much more dangerous. - It is not good engineering to give something away for free with no method of recovery, even if that resource is plentiful. - The IETF should not be creating a new worldwide RIR. - The IETF should not be dictating fees (free). (more to the point, a worldwide RIR, with the language and other issues will be expensive, yet it has no method of income) - Since this is a free method of globally unique space it has a high likelyhood of being routed on portions of the public internet. Indeed, this problem was quickly dismissed by the authors (see http://www1.ietf.org/mail-archive/web/ipv6/current/msg03848.html) who completely missed the boat. It's not the rich who would demand their prefix be routed, but the poor. We already have situations where parts of Africa and Asia claim the fees for IP space are too high. If they had access to "free" "global" space they would jump on it, and later if the rest of the world wanted to contact that region they would almost certainly have to route it as well. - The "ownership should be private", yet the reason for a registry is to verify ownership and prevent hoarding. I'm not sure how those are combatable. - I think the IPv6 groups continue in their fantasy that people will manage multiple, complete overlay networks to fix numbering issues. More to the point, it seems to me the working group is highly enterprise focused, and seems to want to give enterprises what they (think) they want with little concern for how it impacts the global Internet. Since this is a list of providers, I encourage you to read the drafts, and submit your comments to the working group. The information for the working group is at http://www.ietf.org/html.charters/ipv6-charter.html, and includes their mailing list archives and information on how to subscribe and/or post. Even if you disagree with me, much like voting the important thing is that you voice your opinion. -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request(a)tmbg.org, www.tmbg.org

Netflow analysis best pratice and tools ?
by Joe Shen 18 Nov '04

18 Nov '04

Hi, We plan to set up netflow analysis in our backbone. It's hoped to be able to track communication demand inside our AS as well as our AS and other ASes. It also expected to be able to support route optimization and to detect abnormal network behavior . And, report generation is needed too. Is there any best pratice or recommendation on how to employ netflow collecting in ISP backbone? Is there any software or products covering all above ? thanks Joe __________________________________________________ Do You Yahoo!?
