by Shahab Vahabzadeh 21 May '12

21 May '12

Hi there, Has anybody experience about running and OSS System in enterprise level? And do you have any idea about it? For example for an ISP who is running users more than 20K or 30K, there must be some good solutions to integrate all systems like: Radius, Billing Systems and CRM For example after searching and asking friends I have some ideas about Radius to use: radiator Is there anybody who has analyse such a systems before in his ISP? Need sharing here :) Thanks -- Regards, Shahab Vahabzadeh, Network Engineer and System Administrator PGP Key Fingerprint = 8E34 B335 D702 0CA7 5A81 C2EE 76A2 46C2 5367 BF90

Re: Historical records of IP allocations
by Lucas Wang 21 May '12

21 May '12

We started keeping track of whois databases from March 20th this year, and our earliest data shows it belongs to a Russian company called DIMEDIA LLC. Now the latest whois shows it belongs to "OVH Telecom" located in France.

Commerical Backup Solutions
by Paul Stewart 20 May '12

20 May '12

Hey folks. I'm hoping for some input from operational folks on backup solutions for servers. We are looking for a commercial backup solution with a nice reporting dashboard etc. It must support full/incremental backups on Windows and various flavors of Linux. We would also be looking for bare metal image/recovery abilities. To date, we've been fond of Acronis until we got the quote for it .. Initially we would be looking at 50-80 servers and growing it up from there to probably 150-200 boxes. Some of these servers are geographically dispersed. At the moment we have been using Bacula but it lacks bare metal options and doesn't have any nice reporting options (Executive Dashboard etc) Thanks for any input, Paul

NANOG 55 DNS Track
by Mehmet Akcin 18 May '12

18 May '12

Hello everyone, NANOG 55 will take place in Vancouver , Canada June 3-6 , 2012. I will send more information about DNS Track timing and details of the track later. I am sending this email to ask NANOG attendees to help us organize a better track by letting us know what topics they want to see covered about DNS. We are also inviting parties who are DNS Software providers, service providers, experts, and researchers to join and present about what they think is interesting. Please contact me directly if you want to briefly bring something interesting about DNS to this Track's and their attendees attention. Since the whole track will be 90mins and we want to allow as much as talks to take a place it would be good idea to limit any specific talk to 15 mins and keeping it really operational , brief and clear would be great idea. as I said earlier as soon as track details are decided, I will send a second e-mail to let the community know. thank you for your interest. mehmet

YouTube Video Streaming
by Thames 18 May '12

18 May '12

I would like to get some input for the following problem we face with YouTube video streaming. We are an ISP in Singapore and peer with Google at Equinix and SOX (Singapore Open Exchange), For about 2 weeks we have been facing choppy streaming or continuous buffering on various YouTube videos. These problem videos are streamed at HD or original quality. Our troubleshooting narrow down to those bad videos being streamed to us from outside Singapore. We contacted Google support, they are confused too, as why we are served from a cache server in Poland on one of the videos. The case has been escalated within Google, unfortunately no update from them since. Not all YouTube videos are bad through us, some 45 minutes videos can fully buffered within seconds on HD or original quality, of course the IP we streamed for these videos are through our local peering with Google. -Thames
