(I'm starting to guess I'd finish sending these out faster if I stopped falling asleep on my keyboard so often... --Matt) 2006.06.07 Welcome to Wednesday morning http://www.nanog.org/ click on Evaluation Form Let us know how the M-W vs S-Tu format; next time will be S-Tu due to ARIN joint meeting, but need more feedback! Bill Woodcock, been on program committee And lightning talk people need to send their slides to Steve Feldman!! Elliot Gilliam, ISP community, notifications to Smart Network Data Services [slides are at http://www.nanog.org/mtg-0606/pdf/eliot-gillum.pdf AGENDA postmaster services SNDS problem goal today tomorrow motivation feedback/dialog questions/discussion Postmaster--starting point for any issues you have sending mail into Hotmail/MSN Live. It's like AOL skunkfeed, you can do junk mail reporting. Lets you see what bad stuff is coming from your domain. SenderID Site is at: http://postmaster.msn.com/snds/ Problem: bad stuff on the internet (spam, phishing, zombies, ID theft, DDoS) makes customers unhappy. Solution #1 -- try to stop it before it hits customers doesn't really *solve* the problem Solution #2 -- take what we learn, apply it upstream, get more bang for buck #2: #1 is too low ISP-centric efficiency solution #1, n ISPs have n-1 problems, total is O(n^2) n ISPs have 1 problem (themselves), total is O(n) reduces work of the overall system. Crux today people and ISPs are measured by how much BAD stuff they *receive* Not judged by what they send out. similar to healthcare industry no tight feedback loop to ISP behaviour nice quotes on slides http://www.circleid.com/posts/how_to_stop_spam 7 step program (like 12 step, but shorter) 1: recognize the problem: SNDS 2: believe that someone can help you : Me 3: Decide to do something : You 8: Make an inventory of those harmed : SNDS 9: Make amends to them : Tools 10: Continue to inventory : SNDS 12: Tell others about the program : You What is SNDS Website that offers free, instant access to MSN data on activity coming from your IP space data that correlates with "internet evils" informs ISP to enable local policy decisions Automated authorization mechanism uses WHOIS and rDNS users are people not companies A force multiplier attempt. You can do it on your own, no need to sign up your company officially as long as you're an rWHOIS/WHOIS contact. SNDS goal: provide info which allows ISPs to detect and fix any undesired activity. qualitative and quantitative data "No ISP left behind" stop problems upstream of the destination Bring total cost of remediation to absolute minimum keep service free Make internet a better place. We have data! Windows Live Mail/MSN Hotmail is a spam and spoofing target. 4 billion inbound mails/day 90/10 spam/ham by filtering technologies User reports on spam, fraud, etc. Inbound mail system slide--ugly to read, too dark. SNDS website slide shown. You can see daily aggregated traffic from your network; activity periods, IPs, commands and messages seen on port 25, samples of exchanges. Filter results on your mail rate at which users press "this is junk" on your mail. Trap counts for when IPs hit their junk filters. comments column is catch-all for anything else they might put in; like open proxies, when tested positive. "export to CSV" button, so you can feed the data in to your own systems if you want. Today's Scenario Illustrate magnitude and evidence of a problem. additional resources monitoring infrastructure SNDS Stats 2500 users mostly senders 67 million IPs 10-20% of inbound mail and complaints Output drops by 57% on /24+ when monitored by SNDS SNDS tomorrow Usability signup by ASN better support for upstream providers access transfer Utility programmatic access Data virus-infected emails phishing honeymonkey sample messages Expand the the coverage, try to hit more of the problems on the net. Provide sample messages, compelling evidence when facing customers This hasn't shipped yet, it's what he's hoping to have in a month or two. Tomorrow's Scenarios Lowered barrier to entry recurring "cost" ISP types end-user tier 1/2 monitoring, tier 2/3 directly attack more than just spam virus emails -> infected PCs, outbound virus filters phishing/malware hosting -> takedowns. Is asymmetric routing a sign of people trying to launch hidden abuses of the net? Looking to hit more issues, like spotting virus-laden messages; either infected, or an open relay. Hoping that automation speeds response. Safety Tools Stinger: http://vil.nai.com/vil/stinger Nessus: http://www.nessus.org/ [oy, read the list from his slide, it's long.] green items on the list are free, others are pay-for products. Pay-for isn't necessarily a bad thing if you get benefit! Safety tool breakdown from MSN on next slide. Motivation: Hypothesis: everyone benefits Customers: infected uses get fixed safer, cheaper, better internet experience ISPs solution #1 isn't solving the problem altruistic is the "new" selfish Microsoft only benefits if everyone else does make business case why they're doing this. They need to stop paying costs of trying to deal with spam. Wants to get benefit of being one of the people seeing a cleaner internet ISP Motivation Customers they're unhappy, unsafe they like people who fix that be the hero retain customers win new ones fixing has more benefits than bandaging [bandaging is just sticking fingers in the dike, it doesn't scale, eventually we run out of fingers to stick in the holes] cost reductions bandwidth--slow growth demands support--fewer complaints to your help desk. Community NANOG Motivation alternatives Industry scorecard public recognition public shame Logo ISP program--how clean are you? Business case Some nice quotes from different people around the business case needed here. appeal to cost reduction and revenue generation this is starting to happen. let your sales and marketing people know about this. Boston university business case, students arriving with computers presented danger/load to their help desk. Qwest provides windows/one software to their users. Feedback: usability--how easily can you work with it? utility--what can you do? what's missing tools to aid customer remediation need IPv6 support at some point how do ISPs see cost vs benfits costs, benefits, NANOG aggregation how do we get critical mass? msn-snds(a)microsoft.com Discussion: How does SNDS fit into the larger ecosystem relationship to senderBase.org SCOMP/JMRP REACT adam, rick at support intelligence Yahoo is working on a system like this, Irene Lai is here to work on that, email her if you're interested. Should/how do other ISPs provide this? common schema, authorization, authentication federation, delegation, aggregation Forum bof/track? NANOG/MAAWG? Mailing list: upstream(a)mipassoc.org Conclusion: http://postmaster.msn.com/ http://postmaster.msn.com/snds/ Try it! tell people about it! Q: Matt asks whether Microsoft will point their own systems at it, since Nick Feamster's presentation showed on slide 12 that Microsoft was #10 on the list of spam *sources* that his honeypots saw? A: Yes, he is connecting the systems that track mail sending from Hotmail to this as well, so that they can start making sure they're cleaning their own house as well. on to next talk.

2006.06.06 NANOG-NOTES MPLS TE tutorial
by Matthew Petach 09 Jun '06

09 Jun '06

(still here, just been really busy at work today; will try to finish sending the notes out tonight. --Matt) 2006.06.06 MPLS TE tutorial Pete Templin, Nextlink [slides are at: http://www.nanog.org/mtg-0606/pdf/pete-templin.pdf http://www.nanog.org/mtg-0606/pdf/pete-templin-exercise.pdf He works in a Cisco shop, no JunOs experience Operator perspective, no logos Traffic engineering before MPLS --the "fish" problem. two parallel paths, one entry router, one exit router, you end up with all traffic taking one path, not using the other path. IGP metric adjustments can lead to routing loops hard to split traffic No redundancy left over if both paths filled, but can be good for using 2 out of 3 paths. MPLS TE fundamentals Packets are forwarded based on FIB or LFIB FIB/LFIBS built based on RIB TE tunnels; TE tunnel interface is a unidirectional logical link from one router to another. Once the tunnel is configured, a label is assigned for the tunnel that corresponds to the path through the MPLS network (LSP) TE tunnel basics Once traffic is routed onto the tunnel, the traffic flows through the tunnel based on the path. Return traffic could be placed onto a tunnel going the opposite direction, or simply routed by IGP Key terms for TE Headend router on which the tunnel is configured Tail destination address of tunnel Midpoint router(s) along the path along the tunnel LSP Basic TE config Global: mpls traffic-eng tunnels IGP: must be OSPF or IS-IS mpls traffic-eng rouer-id Loopback0 mpls traffic-eng <area X | level2> physical interfaces mpls ip mpls traffic-eng tunnels tells IGP to share TE info with other TE nodes interface TunnelX ip unnumbered loopback0 borrow the loopbak's address so we can forward traffic down the tunnel tunnel mode mpls traffic-eng tunnel destination <a.b.c.d> tunnel tail tunnel mpls traffic-eng path-option 10 dynamic find a dynamic path through network best path with sufficient bandwidth will discuss path selection in a bit Where are we at? Tunnels go from headend to tail end through midpoint routers over a deterministic path we know what commands go on a router for the global physical interface tunnel interface commands TE and bandwidth Physical interfaces can be told how much bandwidth can be reserved (used) ip rsvp bandwidth X X TE tunenls can be configured with how much bandwidth they need: tun mpls traff bandw Y Tunnels will reserve Y bw on outbound interfaces, and find a path across the network wth X(unused)>Y BW. This prevents oversubscription, or at least helps control it. You can allow for burst room, but for now we'll stick with static, non-oversubscribed links. TE BW operators can adjust the tunnel bandwidth values over time to match changes in traffic. If tunnels are dynamically placed, the tunnels will dynamically find a path through the network with sufficient bandwidth, or will go down. TE auto-bandwidth magic Tunnels can be configured to watch their actual traffic as in "shw int <blah>| inc rate" every five minutes, and update their reservation to match, at periodic intervals. Dynamic reservations to match the live network Bandwidth is 'reserved' using RSVP but not "saved" for TE Often buys enough time to identify the surge, see where the traffic is coming/going. The number is only a number in control plane; no actual impact on data plane, no shaping, no control on real data flows. tunnel mpls traffic-eng auto-bw frequency Y each auto-bw tunnel does "sh int" to capture its rate every 300* seconds each auto-bw tunnel updates "tunn mpls traff bandwidth X" every Y seconds The config actually changes; this will impact your RANCID tracking. It uses highest measured rate during the interval Y May want to tweak your load-interval, since it's a decaying function over time; 5 minute is a fairly smooth value. May need to tweak config check-in system to avoid getting flooded with bandwidth adjustments. Covered: TE tunnel basics router config basics general concepts about TE and bandwidth In this case, the shortest path that has X BW available for reservation actually, bw X at or below priority Y, but that's later. SPF calculations step 0: create a PATH list and a TENT list step 1: put "self" on PATH list. step 2: step 3: put PATH nodes' neighbors on TENT list step 4: if TENT list is empty, stop. step 5: jump back to step 2: Example exercise -- calculate router A's best path to router D using the handout. CSPF notes No load sharing is performed within a tunnel; as soon as a path is found, it wins CSPF tiebreakers: lowest IGP cost largest minimum available bandwidth lowest hop count top node on the PATH list Creating paths -- can be created dynamically, or statically via static paths. Dynamic: tunnel mpls traff path-option X dynamic Explicit paths paths can be crated manually by explicitly creating a path "ip explicit-path name <name?>" next-address X next-address Y tunnel mpls traff path-option X explicit name blah Paths can be created manually by explicity configuring a path that excludes an address; use any link EXCEPT this one. for backup links, oob links, etc. can't combine exclude-address and next-address on the same explicit path. Q: if all other paths go away, will an excluded path still be used? A: only if you have a fallback option of "dynamic" can't both include and exclude on same path. A TE tunnel can have multiple path options. lowest cost path option is attempted higher-cost paths attempted sequentially until a path can successfully established, or failure Usually best to have a dynamic option as the highest-cost option, to ensure you don't fall back to IGP (and lose traffic matrix accounting!) CSPF checks tunnel path options in sequence for one that has sufficient information. OK, we've got tunnels now--how do we share info around the network? TE info is shared around using IGP available bw per interface eight priority levels high priority tunnels can push low priority tunnels out of the way some dynamics as far as tunnel vs interface sizing administrative weight (TE specific IGP metric Affinity (customizable) You can configure different interfaces with bits that indicate territorial restrictions, or high-latency links, etc. Use the interface affinity bits, and match/exclude tunnel affinity bits to include or exclude certain links. This information is distributed immediately for "significant" changes periodically for "insignificant" changes immediately, if a change causes an error Significant changes occur when available bandwidth on an interface passes preset thresholds customizable with 16 thresholds. (based on percentages) Key points where information is passed from device to device. Insignificant changes flooded every 3 minutes, significant flooded immediately, by default. If a new path (dynamic or static) appears that's better than the current one re-optimize periodically, every hour from tunnel bringup by default manually "mpls traffic-eng reoptimize" event-driven when a link comes up optional: requires "mpls traff reo events link-up" not so good with flapping links, though. If you have a flapping link, TE tunnels will stay off that link for about an hour; you have flap dampening in your network. Up next, how to put IP traffic on tunnels static routes "ip route x.x.x.x y.y.y.y tuZ" policy-based routing route-map PBR permit 20 match ip addr ACL set ip next-hop tunX Autoroute Autoroute treat this tunnel as though it's a logically directly connected link to the tunnel tail updates the local router's RIB/FIB with "tunnelX" in place of the IGP next-hop; preserves the IGP cost all the way to the tail. One line of config per tunnel; it updates the LOCAL router's RIB/FIB; prior routers not made aware of this router as a next-hop for the tunnel tail. This is supported for IS-IS, but can be more difficult; you increase number of links in your IGP pretty quickly. tunn mpls traff autoroute announce autoroute and load-sharing parallel tunnels will load-share inversely proportional to their configured bandwidth auto-bandwith can really muck with these values! load-sharing can be tuned separately with "tunn mpls traff load-share X" Limited to CEF 16 buckets, depending on when it measures, can end with values drifting apart. If you use same "X" on two tunnels, they will load share equally. IGPs can load-share over equal-cost paths BUT TE tunnel cannot load-share over multiple physical interfaces TE diagnostics show ip route X sh run int tuX sh ip rsvp reservation show mpls traff tun suboptimal constr none shows headend tunnels taking suboptimal paths to the tunnel tail (eg, different from IGP best path) show mpls traff tun detailed info for all tunnel headends bandwidth info (auto-bw) MPLS labels, hop by hop path show mpls traff tun role <head|middle|remote|tail> remote is non-headend (not originating or ending on this router) show ip rsvp interfaces shows max allocated bw on an interface. MPLS VPNs if a tunnel tail is not the egress PE, add "mpls ip" to the tunnel configuration PE-P-P-PE-PE --adds another label onto the stack. If the last router VPN isn't on penultimate router, the TE label won't be recognized, it'll be dropped. This adds the TE label back on, keeps the LDP label as well as the VPN label still intact Add "mpls ldp discovery directed-hello accept" to config If you have unidirectional tunnels, that way when you're bringing up tunnels LDP info can be exchanged as you're going. Multicast: RPF calculations are normally based on unicast RIB Unidirectional TE tunnels cause RPF failures add "mpls traffic-engineering multicast-intact" to IGP config Bases RPF checks on RIB BEFORE TE tunnels are substituted Questions? templin at templin.org Swap to looking at operational network for some troubleshooting views. About 150-200Mb traffic aggregate, 4 pops, DAL and Houston, four parallel DS3s, 2 between core1's and 2 between core2's 30mbit IP RSVP reservation; TE kicks in, and moves traffic. Houston intercore links tends to not have traffic unless TE has kicked in. Aggressive 15 minute auto recalculations, since surprises can kick up fairly quickly.

2006.06.07 NANOG-NOTES DNSSEC bootstrapping with DLV
by Matthew Petach 09 Jun '06

09 Jun '06

(last notes from NANOG37, yay! I definitely fell further behind this time around than in Dallas. Unfortunately, I don't think I'll be allowed to go to St. Louis, so I probably won't be able to provide notes for NANOG38. --Matt) 2006.06.07 Deploying DNSSEC--bootstrap yourself Joao Damas, ISC [notes are at http://www.nanog.org/mtg-0606/pdf/joao-damas.pdf DNSSEC status standard is complete and usable some minor nits with regards to some privacy issues 2 implementations: NSD, BIND at least one DNSSEC aware resolver (BIND 9.3.2 and later) Really, you just need some data. DNSSEC follows a hierarchical model for signatures. sign the root zone get root zone to delegation sign TLDs get TLDs to delegation-sign SLDs, etc. Today, the root zone remains unsigned likely will be this way for some time Very few TLDs have signed their zones and offer delegation signatures .se, .ru, .org DNSSEC provides for local trust anchors you can use trust-anchors clause in BIND problem: if you have too many, it becomes a nightmare to maintain, so it doesn't get used. very manual process Enter DLV, domain lookaside validation it's an implementation feature, not a change to the protocol; matter of local policy enables access to a remote, signed repository of trust anchors, via the DNS implemented in BINDs resolver so far more to follow? unfortunately, requires you to trust remote repository DLV lookup a DLV enabled resolver will try to find a secure entry point using regular DNSSEC; only if it fails is DLV used, if it is configured. [picture of DLV lookup chain] On resolver (BIND) add to named.conf in the options section //DNSSEC conifg dnnssec-enable yes dnssec-lookaside . trust-anchor dlv.isc.org.; get the key from ISC's web: http://www.isc.org/ops/dlv ISC is operating a DLV registry free of charge for anone who wants to secure their DNS Likely some closed orgs will use their own (eg mil) have a look, start using it! Any questions? Q: Mark Kosters, Verisign: Any plans to configure DLV registries per TLD? A: BIND code only allows for one right now. Q: Would be good to allow it to be configured per TLD. Q: Randy Bush, IIJ: some feeling or understanding how IANA, root would validate keys/zones it has keys for; don't understand how ISC proposes to validate keys it would be storing. He suggests they publish the security policy. A: In case of registrars proxying keys; they trust registrar. Otherwise, it's like PGP; show me your face, show me your key. Q: Paul vixie, ISC, following up on Mark Kosters; you can only have one DLV for any point in the namespace; you can specify a different one for a TLD than root; that allows a TLD DLV to be paranoid, like .mil. who doesn't want to trust anyone else with key information. If every TLD wanted to do that, they would find high levels of cut-and-paste fatigue, so ISC will operate a root level DLV server as well. Q: Rick Wesson, runs Alice's Registry, a small registrar. he's considering doing this, he can help DNS holders register their keys if people are interested, and will help get them into the DLV tree. Q: Sam Wiler?, Sparta: concerns from Randy about how ISC will authenticate the entries. Registrars should consider running their own DLV servers, as they have the relationship with the domain holder. Code? Apparently you don't need code... NANOG 37, ending slides. 425 attendees, 118 first timers lots of countries most USA, 11 canada, scattered others. ISP, then NSP, then other categories. top 3 companies represented: Cisco, Juniper, Equinix HUGE thanks to Rodney Joffe and Neustar for puling off a miracle to make this happen at the last minute! Thanks to sponsors, bear, gear, other. Susan R Harris, many thanks to her for all the work she has put in over the years and to make this happen! Also huge thanks to all the other people at Merit And we'll see you in St. Luis, Oct 8-10th, joint meeting with ARIN, things set in stone. Network will go down in 30 minutes or so--pack up and go home! :) I think that was the fastest closing I've seen at a NANOG yet. ^_^;;

2006.06.07 NANOG-NOTES Anycast benefits for k root server
by Matthew Petach 09 Jun '06

09 Jun '06

Break ends at 11:40, PGP signing will take place, and don't forget to fill out servers. ANYCAST fun for the final sessions. Lorenzo Colitti, RIPE NCC [slides are at: http://www.nanog.org/mtg-0606/pdf/lorenzo-colitti.pdf Agenda: introduction latency client-side server-side Benefit of individual nodes Stability Routing issues Why anycast? root server anycast widely deployed c, f, i j, k, m at least reasons for anycasting provide resiliency: eg contain DOS attacks spread server and network load increase performance but is it effective? measure latency ideally for every given client, BGP should chose node with lowest RTT. does it? from every client, measure RTTs to anycast IP address service interfaces of global nodes (not anycasted) for every client, compare K RTT to RTT of closest global node a = RTTk/min(RTTi) if 1, BGP is picking right node if > 1, BGP picks the wrong node if <1, seeing local node. Latency with TTM: methodology DNS queries from ~100 TTM test boxes dig hostname.bind see which host answers extract RTT take min of 5 queries check paths to service interfaces; is it same as prod IP according to RIS, mostly 'yes' TTM probe locations, mostly in europe Latency with TTM: results (5 nodes) most values are close to one; generally BGP doing pretty good job. from 2 nodes to 5 nodes (2 nodes, April 2005) (5 nodes, April 2006) mostly same results, clustered around one, whether 2 or 5 nodes. consistency of 'a' over time average of that over time. TT103 is outlier calculated over time, threw out that one outlier. results are pretty consistent. average is little higher than one, mostly consistent over time measuring from servers TTM latency measurements not optimal locations biased towards europe limited number of probes (~100) don't reflect k client distribution how to fix? ping clients from servers much larger dataset methodology process packet traces on k global nodes extract list of client IP addreses ping all addresses from all global nodes plot distribution of 'a' 6 hours of data 246,769,005 queries 845,328 unique IP addresses CDF of 'a' seen from servers results not as good as seen by TTM only 50% of clients have a = 1 about 10% are 4x slower/farther. probably due to TTM clustering in europe latency conclusions 5 node result vs 2 node, comparable, at least in TTM non-TTM results not so rosy. How many nodes are needed--is 5 enough? evaluate existing instances how to measure benefit of an instance? Assume optimal instance selection that is, every client sees closest instance this is upper benefit of benefit consistent to see if we've reached diminishing returns for every client, see how much its performance if the chosen node didn't exist. B is loss factor, how much a client would suffer if an instance were knocked out B = RTTknockout/RTT... Graph for LINX; 90% of clients wouldn't see an impact if it went away; 10% would see a worsening. geographic distribution pretty wide AMS-IX about 20% would suffer performance degregation; busiest two nodes, see a lot of clients, important to k deployment. If they plot it for both LINX and AMSIX together, about 65% wouldn't be affected, most of others would see 4x, 10% would be 7x worse. So taken together, the *two* nodes are important. Tokyo; best node for few clients; but those served, BADLY served by others; about 10% who would go more than 7x if it went way, those clients mostly Asia. Miami node at NOTA, moderate benefit for some clients, US and southAm would be badly served by europe or Tokyo. Delhi node is mostly ineffective, most would be served better by other nodes. Condense the graph into one number to get a value for effectiveness of each node. weighted average of B for each client. if benefit value is 1, node doesn't provide any benefit at all. larger numbers show higher benefits. Europe, when taken together, high benefit, as is Tokyo; Miami node not so effective, and Delhi is nearly ineffective. Does anycast provide any value then? knock out all except LINX; dark red curve (pre 1997) 10% wouldn't notice, 85% would get worse, benefit value is 18.8, so anycast does bring value. Stability the more routes competing in BGP with more nodes doesn't matter for single packet UDP exchanges does matter for TCP Look at node switches that occur. collect packet dumps on each node. extract all 53/UDP traffic k nodes only NTP synchronized if IP shows up on two nodes, log a switch. 5 nodes, april 2006, 0.06% saw switches 2830 switchers out of 845,328, 0.33% switchers no big issue with instance switchers. Routing issues k-root structure 5 global nodes (prepended) linkx, amsix, tokyo, mia, del different prepending values no-export causing reachability TT103 has value of 200, the graph axis is cut. tt103 is in Yokohama; Tokyo is 2ms away; but the query goes to Delhi through Tokyo to LA. 416ms vs 2, so value is 208. Thanks to Matsuzaki and Randy Bush, got BGP paths from AS2497 bad interaction of different prepending lengths need to fix prepending on Tokyo node. Delhi had shorter prepending. no-export and leaks local nodes can be worse than global nodes tt89, seeing Denic local node, 30ms instead of going to London. Local node, if no-export is ignored, announced to customer, they are more specific, leak to customers. no-export can lead to loss of reachability http://www.merit.edu/mail.archives/nanog/2005-10/msg01226.html problematic interaction of no-export with anycast use no-export to prevent local nodes from leaking if have an AS whose providers all peer with a local node and honor no-export customer never sees route for k IP address. solution, send out a less specific, covering prefix. Q: Mark Kosters, Verisign--saw much higher switching rates; can he define switching better? A: if an IP is seen at one location, then shifts to a different site, that's one switch; going back to the first node would be a second switch.
