SORBS?
by trainier＠kalsec.com 26 Aug '09

26 Aug '09

I need a SORBS maintainer to contact me. The SORBS site reports the site and databases are in maintenance mode for the second day in a row. One of my domains was legitimately listed, but now that I've resolved the problem, I'm unable to request removal. Regards, Tim R. Rainier Systems Administrator II Kalsec Inc. www.kalsec.com

email address and SMTP server
by Juraj Benak 24 Aug '09

24 Aug '09

Good morning, I'm having a problem with my SMTP server installed on W2k3 server. Before we used SMTP of our ISP but because messages were delayed by few hours on regular basis I decided to install SMTP server (Exchange server installation is busted and will have to reinstall the server to get it work). For now I have a problem with one address which is working from my ISP's SMTP server but not from my server. I have setup my ISP's DNS servers and there isn't problem with other recipients, only this one. I tried to check the domain record for that email and it was OK. I checked via MX record database what servers they are using and the servers were fine as well. I got this response: Final-Recipient: rfc822; Action: failed Status: 4.4.7 Is there any way how to check it or can you tell me what could be the problem? The domain is boomerangaustralia.com. Thanks Juraj

ISP Security BOF -- NAOG 47
by Warren Kumari 24 Aug '09

24 Aug '09

"The time has come," the Walrus said, "To talk of many things", like how NANOG 47 is fast approaching and how I am *sure* that you would like to participate... This is *your* chance to talk about interesting security related topics and provide some feedback on what you would (and would not) like to hear about... Some security thing been buggin' you all year? Some topic that you feel strongly about and would like a change to inform others about? Step right up and give a talk -- this BOF is traditionally fairly laid back and easy going, so its a low stress introduction to presenting... Slides are welcome, but not required... W

new collaborative network forensics tool for massive pcap libraries
by Thomas Maufer 24 Aug '09

24 Aug '09

I wanted to share with the NANOG community this likely interesting bit of pcap wrangling technology that Mu announced yesterday. Here is the announcement on the new network forensics application within pcapr<http://www.pcapr.net/> : Collaborative Network Forensics Mu Dynamics ( http://www.mudynamics.com/ ) took the recently published dataset by the *U.S. Army Information Technology & Operations Center* ( ITOC <http://www.itoc.usma.edu/> ) from the “2009 Inter-Service Academy Cyber Defense Competition<http://www.itoc.usma.edu/research/dataset/index.html>” as well as the *Schmoo Group’s* “Capture the Capture the Flag<http://cctf.shmoo.com/>” ( CCTF ) dataset (for a grand total of *15.0 GBytes…26.3 million packets*), and indexed them all to enable contextual search and instant access to packets, not to mention Hacker-News/Twitter-style one-liners attached to packets and searches for a community-oriented collaborative forensics application. Check it out (read the blog, linked below, first): - http://bit.ly/12I62D for the blog and - http://www.pcapr.net/forensics for the online app Enjoy! A brief background on pcapr: It’s a web-based pcap repository (hence, pcapr) that has some powerful pcap manipulation capabilities. The pcaps on pcapr are fully decoded and editable and you can manipulate them in novel ways: You can identify and isolate or decode streams, remove garbage from the pcap (i.e., extraneous packets from protocols that you aren’t interested in), reorder packets, save subset or modified pcaps without destroying the original, etc. All this happens at http://www.pcapr.net/, which is open to the public. If you can access the web, you can access the pcapr database and upload your own local pcaps for analysis. All registered users can upload up to 5 pcaps into a scratch space that is private to them. There are currently *250*protocols represented on pcapr across over 1500 pcaps, in addition to the forensics application with its 26.3 million packets. Finally, a free denial-of-service traffic generator is available on pcapr; you can turn any packet you find on pcapr into a DoS template. All the best, ~tom -- Thomas Maufer Mu Dynamics, Inc.

Best Effort QoS Drop Profile Input
by Brad Fleming 24 Aug '09

24 Aug '09

Hello all, We are working on fine tuning drop profiles for customer edge routers (Juniper J-2320 in almost all cases) and I was hoping for some input from those who are smarter and have done this before. Basics: - Sites each have a single T1 into a service provider L3 VPN - Queue depth is 500ms - Sites typically will use 90%+ of their line rate while school is in session (education network) - Services offered include: real-time video (in a different queue) and best effort (serviced by the queue in question) - Nearly all BE traffic will be TCP (typical web, email, etc traffic) We were never able to find a good best practice for configuring drop profiles on edge devices. We've been using the following with OK results but I was hoping to have some external, more experienced eyes take a look... drop-profiles { be_any { fill-level 50 drop-probability 5; fill-level 70 drop-probability 20; fill-level 90 drop-probability 50; } Has anyone ever run across a publicly documented best practice for drop profile configuration? Does anyone have suggestions on ways to improve the configuration above? Any input is much appreciated, thanks in advance! -brad fleming

Re: Redundancy & Summarization
by Brian Dickson 22 Aug '09

22 Aug '09

> My institution has a single /16 spread across 2 sites: the lower /17 is > used at site A, the upper /17 at site B. Sites A & B are connected > internally. Currently both sites have their own ISPs and only advertise > their own /17's. For redundancy we proposed that each site advertise > both their own /17 and the whole /16, so that an ISP failure at either > site would trigger traffic from both /17s to reconverge towards the > unaffected location. There are two different ways to achieve almost-identical results. However, one is a 50% more "green" than the other, i.e. friendly to other network operators. These two choices are functionally equivalent, and possible, only because things currently work for both your /17's. Here are the two ways to do this: One is: - announce /17 "A" and /16 from uplink ISP-A - announce /17 "B" and /16 from uplink ISP-B - This results in 3 prefixes globally: A, B, and /16. The other is: - announce /17 "A" and /17 "B", with different policies (i.e. prepend your AS once or twice), at *both* ISPs. - This results in 2 prefixes globally: A and B. In all cases, as long as one ISP link is up, there is a path to both A and B. In most cases, the best path to A or B, is *mostly*, but not completely, under your influence. So, the main difference to everyone else is, the presence or absence of a routing slot (/16), and/or extra copies of A and/or B. The routing slot occupies a slot in data-forwarding-plane hardware that is very limited. The extra copies of A and B (and extra copies of your AS in the AS-path) only eat cheap control-plane memory. If everyone did things nicely, we would not have as much of a crisis on the hardware side as we (collectively) do. Please consider being part of the solution (announcing only /17's, but in both places) rather than part of the problem (adding a new redundant /16 to everyone's routers, including in the hardware slots.)
