RE: Slight OT: NASA World Wind project looking for support from network operators.
by Matt Mills 08 Jun '05

Since there seems to be a lot of list-related chatter suggesting we use bittorrent for our distribution needs, I'd like to respond on-list to those. Why we don't use Bittorrent for distribution of the program: Actually, theirs no real problem here, we have used bittorrent in the past. The only real issue is that there are so many non-savvy users, that most of the users just click past the bittorrent link and go straight for the HTTP links. Why we don't use Bittorrent for the distribution of the satellite data: This is just where P2P and satellite data don't mesh. In order for the program to work and not be incredibly frustrating and boring, the tiles (imagery and elevation) have to be loaded at a somewhat speedy rate. Due to the way P2P has to find and connect to peers before it can start downloading tiles, it is just too slow for it to work well (and not make everyone unhappy/ the program useless). The other problem here is that there is hundreds of gigabytes composing of millions of files, so to be able to get full coverage of just one dataset would be an enormous effort. I also received a few responses recommending Coral CDN. Unfortunately for the program, Coral has a file size limit of 50 MB (Client is currently 188 MB). Unfortunately for the satellite data, since there are so many small files, it would be quickly pushed out of the cache. Also, coral isn't all that speedy with responses, so it makes the program moderately sluggish. Also, while I'm posting, I'd like to ask if anyone has contact information for someone at Archive.org, could you please contact me with it? I've been trying to get in reach with someone over there but all my emails seem to find a black hole. Thanks to all. Matt Mills

Onsite Generation: A Reminder [was: Battery Maint in LEC equipment]
by Frank Coluccio 08 Jun '05

08 Jun '05

There's been much said here and over in the Cybertelecom list recently about battery provisions by telcos and cable operators, but relatively little has been mentioned about onsite generation. I sometimes point my staff and clients to the messages that were posted here in NANOG, including those of my own, immediately following the attacks of September 11th and lasting into the next month or two. Many here will recall that at that time many hubs and enterprises alike in the downtown area of Manhattan, including the area's Internet exchanges and colos, received a first-hand lesson on the need to maintain preparedness with functioning generators, including fuel and spare parts. Not to mention the need to modify air intakes and exhausts for a new form of threat: Airborne Debris.

Agreed. I joined Nanog initially to be alerted of medium/large-scale outages (used to work for a telco), but then I was pleasantly surprised by the deeper technical "edge" of most participants on this fabulous list. Best of both worlds, IMO.

Problems with Qwest Frame Relay?
by John Neiberger 07 Jun '05

07 Jun '05

By any chance, are any of you seeing any problems with Qwest frame relay or iQ in Colorado? We just had a whole bunch of frame relay PVCs all over the area go down. I've opened a ticket with Qwest, of course, but I haven't heard back from them since I opened it and I'm now on eternal hold with their IP NOC. Have any of you heard anything? Did a frame relay switch bite the dust? Thanks, John --

drone armies C&C report - May/2005

Below is a periodic public report from the drone armies / botnets research and mitigation mailing list. For this report it should be noted that we base our analysis on the data we have accumulated from various sources. According to our incomplete analysis of information we have thus far, we now publish our regular two reports. This month we would especially like to commend Staminus, who contacted us and have since made incredible efforts to deal with the threat. Also, we'd like to mention Internap for their continuous efforts. The ISP's that are most often plagued with botnet C&C's (command & control) are, by the order listed: ---------------------------------- Top 15 with open non-resolved suspect C&Cs by Name: ASN Responsible Party Unique C&Cs Open-unresolved 6517 YIPESCOM - Yipes Communication 60 41 21840 SAGONET-TPA - Sago Networks 90 24 25761 STAMINUS-COMM - Staminus Commu 86 20 4766 KIXS-AS-KR Korea Telecom 43 20 13680 AS13680 Hostway Corporation Ta 22 19 21698 NEBRIX-CA - Nebrix Communicati 24 18 13301 UNITEDCOLO-AS Autonomous Syste 27 17 21788 NOC - Network Operations Cente 29 16 29415 EUROWAN-ASN OVANET - EuroWan d 16 15 13749 EVERYONES-INTERNET - Everyones 24 14 30083 SERVER4YOU - Server4You Inc. 21 14 25700 SWIFTDESK - SWIFTDESK VENTURE 13 13 23522 CIT-FOONET - CREATIVE INTERNET 14 12 27595 ATRIVO-AS - Atrivo 31 11 13237 LAMBDANET-AS European Backbone 11 11 The following table is a historical ranking of the top 10 Responsible parties listed by the number of unique C&Cs in the BBL along with the current number of C&Cs responding as open at the time of the survey.
