MRTG in Fourier Space
by Crist Clark 24 Apr '09

24 Apr '09

Maybe a slightly off topic math-geek kind of question to take time out from the ARIN/death-of-IPv4/IPv6-evangalist thread of the week. Has anyone found any value in examining network utilization numbers with Fourier analyses? After staring at pretty MRTG graphs for a bit too long today, I'm wondering if there are some interesting periodic characteristics in the data that could be easily teased out beyond, "Well, the diurnal fluctuations are obvious, but looks like we may have some hourly traffic spikes in there too. And maybe some of those are bigger every fourth hour." A quick Google search turned up nothing at all. With many EE-types who find their way into network operations and wannabe-EEs already there, I found that maybe a little surprising. I know the EEs love Fourier transforms.

Let me see if I can understand this. We're running out of IPv4 space. Knowing that blatant lying about IP space justifications has been an ongoing game in the community, ARIN has decided to "do something" about it. So now they're going to require an attestation. Which means that they are going to require an "officer" to "attest" to the validity of the information. So the "officer," most likely not being a technical person, is going to contact ... probably the same people who made the request, ask them if they need the space. Right? And why would the answer be any different, now? ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.

The real issue
by Shane Ronan 23 Apr '09

23 Apr '09

Is ARIN, who won't even take back large blocks of space from people who have long ago stopped using it and aren't paying anything for it, prepared to start filing civil suits against people who were assigned / 24's (and paid for them) due to inaccurate declaration?

Bruce Perens: A Cyber-Attack on an American City
by Joe Greco 22 Apr '09

22 Apr '09

http://perens.com/works/articles/MorganHill/ Cyber-Attack on an American City Bruce Perens Just after midnight on Thursday, April 9, unidentified attackers climbed down four manholes serving the Northern California city of Morgan Hill and cut eight fiber cables in what appears to have been an organized attack on the electronic infrastructure of an American city. Its implications, though startling, have gone almost un-reported. That attack demonstrated a severe fault in American infrastructure: its centralization. The city of Morgan Hill and parts of three counties lost 911 service, cellular mobile telephone communications, land-line telephone, DSL internet and private networks, central station fire and burglar alarms, ATMs, credit card terminals, and monitoring of critical utilities. In addition, resources that should not have failed, like the local hospital's internal computer network, proved to be dependent on external resources, leaving the hospital with a "paper system" for the day. [...] Good read, good summary for less-technical people. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.

DSL Subscriber management
by Sherwin Ang 22 Apr '09

22 Apr '09

Hello Nanog! i just would like to see how other operators are handling broadband/DSL subscribers in their BRAS. Currently, we are implementing PPPoE with AAA on our Redback SE's and Cisco boxes. As our subscriber base grows and grows, management of user logins, passwords, password resets, password changes are getting really huge. Some customers also complains about the method of logging in, asking for an easier way to do it or dump logins altogether. We're looking at DHCP/CLIPS for Redback but haven't really tested it since it requires a new license for it. For Cisco, we've been empty so far in looking for a solution wherein we still have accounting and rate-limiting on subscriber vc's. how are network operators in your areas do it? DHCP? if i do DHCP, will i still have the flexibility of sending a radius reply attribute so i could rate-limit the subscribers speed? or still offer speed on demand via radius/time-based upgrade of their rate-limits during off-peak hours? thank you for any insights that you may share. -sherwin

But when he close all the windows no change in downloading speed is observed. our router is C12KPRP-K4P-M Please advise what could be the cause? -- Regards Chandrashakher Pawar IPNOC Customer & Services Operations Tata communication AS6453 mobil + 91 9225633948 + 91 9324509268 learn.chandra(a)gmail.com
