Solved: Apple Time Capsule Not Found in Airport Utility

openingtimecapsuleAlmost all my home computer equipment is composed of Apple products, save for the Windows media center that I’m using to power the TV/display old TV shows/movies/listen to the radio. I’ve been using Windows Vista to power the ‘center until (very!) recently, and for the past two or three weeks have had my Time Capsule and attached AirPort Disk vanish from the network every couple of hours. Given that a lot of my movies and TV shows are on the AirPort Disk, this has been a real problem. Despite the drops, the router-element of the Time Capsule continued to work – I could browse the ‘net, and even run my automated backups using Time Machine, though I couldn’t actually access the data on the Time Capsule!

At first I assumed that the problem was a Windows Vista-related issue. I’d had other issues getting everything set up, and third-parties had mucked around with the media center while I was gallivanting around Ontario a few weeks ago. The only time that the router (and AirPort Disk) become unresponsive was when I used Vista to connect to the AirPort Disk. No issues arose when just browsing the AirPort Disk using a Mac (note: all Macs in the house are running 10.5.7). Continue reading

Draft: What’s Driving Deep Packet Inspection in Canada?

routingpacketsFor the past few weeks I’ve been working away on a paper that tries to bring together some of the CRTC filings that I’ve been reading for the past few months. This is a slightly revised and updated version of a paper that I presented to the Infoscape research lab recently. Many thanks to Fenwick Mckelvey for taking the lead to organize that, and also to Mark Goldberg for inviting me to the Canadian Telecom Summit, where I gained an appreciation for some of the issues and discussions that Canadian ISPs are presently engaged in.


Canadian ISPs are developing contemporary netscapes of power. Such developments are evidenced by ISPs categorizing, and discriminating against, particular uses of the Internet. Simultaneously, ISPs are disempowering citizens by refusing to disclose the technical information needed to meaningfully contribute to network-topology and packet discrimination discussions. Such power relationships become stridently manifest when observing Canadian public and regulatory discourse about a relatively new form of network management technology, deep packet inspection. Given the development of these netscapes, and Canadian ISPs’ general unwillingness to transparently disclose the technologies used to manage their networks, privacy advocates concerned about deep packet networking appliances abilities to discriminate between data traffic should lean towards adopting a ‘fundamentalist’, rather than a ‘pragmatic’, attitude concerning these appliances. Such a position will help privacy advocates resist the temptation of falling prey to case-by-case analyses that threaten to obfuscate these device’s full (and secretive) potentialities.

Universities Struggle to Cope with Anti-Piracy Requirements

copyrightussatireUniversities in the US have been deeply burdened by the Higher Education Opportunity Act that President Bush signed into law last year. In particular, the Act require that “schools ensure they are doing all they can to combat illegal file sharing among students. The new rules, according to the wording contained in the legislation, requires institutions to develop plans to “effectively combat the unauthorized distribution of copyrighted material, including through the use of a variety of technology-based deterrents.” Schools must also “to the extent practicable, offer alternatives to illegal downloading or peer-to-peer distribution of intellectual property.” Any institute found to be non-compliant could lose federal funding” (Source).

To combat unauthorized distributions, technological solutions such as bandwidth shaping and traffic monitoring need to be implemented. Such solutions need to be integrated with advanced DMCA response practices. Of course, some of the companies that are being courted to meet these demands are those that incorporate DPI into their copyright ‘solutions’. I’ve discussed, generally, how these technologies work on campuses from iPoque’s position when writing about one of the company’s whitepapers. In that post, I wrote, Continue reading

Iran, Traffic Analysis, and Deep Packet Inspection

iranelectionLet me start with this: I am woefully ignorant and Iranian politics, and have no expertise to comment on it. I’ll save my personal thoughts on the matter for private conversations rather than embarrass myself by making bold and ignorant statements here. Instead, I want to briefly note and comment on how the Wall Street Journal (WSJ) is talking about Deep Packet Inspection (DPI) and the data traffic that is flowing in and out of Iran.

The WSJ has recently disclosed that Iranian network engineers are using DPI to examine, assess, and regulate content that is entering and exiting Iran. They note that the monitoring capacity was, at least in part, facilitated by infrastructure that was sold by Nokia-Simens. The article proceeds, stating that traffic analysis processes have been experimented with before, though this is the first major deployment of these processes that has captured the attention of the world/Western public. This is where things start getting interesting.

The article notes that;

The Iranian government had experimented with the equipment for brief periods in recent months, but it had not been used extensively, and therefore its capabilities weren’t fully displayed – until during the recent unrest, the Internet experts interviewed said.
