DPI and Net Neutrality's Overseas Weak Spot

Tue, 19 Aug 2008 19:05:11 EDT

An unnamed source at an American ISP says staff there briefly considered using Deep Packet Inspection to comply with an order from Argentina's Department of Justice to block access to a local gambling site. The ISP ended up not going that route, owing to the cost, but some engineers at the company worry that DPI will eventually be implemented on the ISP's overseas network, thereby positioning it for an easier US rollout should Net Neutrality lose out in Washington. Besides being used for traffic-shaping, DPI can also monitor the traffic of ISP subscribers to supply targeted advertising."Read more of this story at Slashdot.

Google Using DoubleClick Tracking Cookies

Tue, 12 Aug 2008 14:05:02 EDT

dstates sends news coming out of the letters the House Energy and Commerce Committee sent to a number of broadband and Internet companies about their policies and practices on user tracking. The committee has now made public 25 responses to its queries, and many companies, including Google, acknowledge using targeted-advertising technology without explicitly informing customers. The Committee is considering legislation to require explicitly informing the consumer of the type of information being gathered and any intent to use it for a different purpose, and a right to say "no" to the collection or use. The submitter notes that, while Google denies using deep packet inspection, if the traffic is a Google search or email to or from a Gmail account, Google does not need DPI to see the contents of the message. "The revelations came in response to a bipartisan inquiry of how more Internet companies have gathered data on customers. Edward J. Markey (D-Mass.) said 'Increasingly, there are no limits technologically as to what a company can do in terms of collecting information... and then selling it as a commodity to other providers.' Some companies like NebuAd have tested deep-packet inspection with some broadband providers Knology and Cable One. Google said that it had begun to use the DoubleClick ad-serving cookie that allow the tracking of Web surfing across different sites but said it was not using deep packet inspection. Google promotes the fact that its merger with DoubleClick provides advertisers 'insight into the number of people who have seen an ad campaign,' as well as 'how many users visited their sites after seeing an ad.' Microsoft and Yahoo acknowledge the use of behavioral targeting. Yahoo says it allows users to turn off targeted advertising on its Web sites; Microsoft has not yet responded to the committee."Read more of this story at Slashdot.

Canadian ISP Hijacking DNS Lookup Errors

Sat, 19 Jul 2008 13:05:01 EDT

Freshly Exhumed tips us to news that Canadian ISP Rogers Cable appears to be redirecting invalid DNS requests to their own search and advertising page. Roadrunner got caught doing the same thing earlier this year. According to the article, "The hijacking appears to be an attempt by Rogers to use its Deep Packet Inspection (DPI) technology to cash in on the mistakes of its users." Freshly Exhumed also reminds us, "As IOActive security researcher Dan Kaminsky has warned in the past, this presents a very serious security problem."Read more of this story at Slashdot.

Covert BT Phorm Trial Report Leaked

Thu, 05 Jun 2008 11:05:02 EDT

An internal BT report on the BT secret trials of Phorm (aka 121Media) Deep Packet Inspection has been revealed on Wikileaks today. The leaked document shows that during the covert trial a possible 18 million page requests were intercepted and injected with JavaScript and about 128 thousand charity ads were substituted with the Phorm Ad Network advertizements purchased by advertisers specifically for the covert trial period. Several ISPs are known to be using, or planning to use, DPI as a means of serving advertising directly through Layer 7 interception at ISP level in the USA and Europe. NebuAd claim they are using DPI to enable their advertising to reach 10% of USA internet users."Read more of this story at Slashdot.

Charter Is Latest ISP To Plan Wiretapping Via DPI

Tue, 13 May 2008 15:05:02 EDT

Charter Communications has begun sending letters to its customers informing them that, in the name of an "enhanced user experience," it will begin spying on their traffic and inserting targeted ads. This sounds almost indistinguishable from what Phorm proposed doing in the UK. Lauren Weinstein issues a call to arms.Read more of this story at Slashdot.

80 Gbps Deep Packet Inspection Hardware Announced

Mon, 12 May 2008 16:05:05 EDT

An anonymous reader writes to tell us that Procera Networks is launching a new weapon on the deep packet inspection (DPI) front. At $800,000 these 80 Gbps tanks aren't going to be sitting in everyone's closet, but it could mean that more traffic shaping is on the way. "The PL10000 can handle up to 5 million subscribers and can track 48 million real-time data flows. That's certainly a potent piece of hardware, but larger ISPs will need more. That's why Procera designed the new machines with full support for synchronizing traffic flows where return traffic might be routed to a different PacketLogic machine. The machine receiving the return traffic can make the machine monitoring the outbound traffic aware that it sees the other half of a TCP/IP conversation, for example, giving the devices more accuracy than those which might only have access to one side."Read more of this story at Slashdot.

NeoOffice 2.2.1 Available For Mac

Following a month or so of their Early Access Program, NeoOffice, the free Office suite for OS X, has just released NeoOffice 2.2.1. New features include support for the native Mac OS X spell-checker and address book; support for high-resolution printing (more than the 300 dpi that previous versions allowed); the ability to open, edit, and save most Microsoft Office 2007 Word, Excel, and PowerPoint documents; and the latest features from OpenOffice.org 2.2.1, which is the code base for NeoOffice. X11 is not required, but for those of you who actually want to use X11, check out the new RetroOffice."Read more of this story at Slashdot.

Deep Packet Inspection and Net Neutrality

Thu, 26 Jul 2007 14:05:01 EDT

Ars Technica has an in-depth feature on deep packet inspection, and it's a disturbing read. ISPs are starting to turn to DPI to monitor their networks, and, more troubling, to look at how they can use it to shape, block, monitor, and prioritize traffic. 'The "deep" in deep packet inspection refers to the fact that these boxes don't simply look at the header information as packets pass through them. Rather, they move beyond the IP and TCP header information to look at the payload of the packet. The goal is to identify the applications being used on the network, but some of these devices can go much further; those from a company like Narus, for instance, can look inside all traffic from a specific IP address, pick out the HTTP traffic, then drill even further down to capture only traffic headed to and from Gmail, and can even reassemble emails as they are typed out by the user.'"Read more of this story at Slashdot.

Next in Browser Development, High DPI Websites?

Sun, 23 Apr 2006 00:00:00 EDT

In a post at the WebKit blog, Dave Hyatt raises interesting points about the future of web development and browsers. He says, that with screens getting more and more pixels, it is imperative website design takes the next step: High DPI Website rendering. This could mean that a CSS pixel (px) is rendered as a 2x2 pixelblock. In the article he also mentions WebKit will be providing possibilities to use SVG for all kinds of purposes, like backgrounds. He calls upon other browser developers to take part in the discussion so that 'concrete standards in this area can be hammered out.'

New Fatal1ty Gaming Mouse

Mon, 09 Jan 2006 00:00:00 EST

steven williamson writes to tell us that Hexus has a quick look at Jonathan 'Fatal1ty' Wendel's approach to a new gaming mouse. At first glace it doesn't seem to have much to offer beyond your average optical mouse. A few of the features are a "four finger" setup with regards to mouse buttons, a mere 1600 DPI but that should be plenty for most, and an exchangeable weight to give it just the right heft.

Fall 2005 Photo Printer Buyers Guide

Wed, 16 Nov 2005 00:00:00 EST

DesignTechnica has some great tips on what to look for when buying a Photo Printer. From the article: 'Some of the best printers offer 9600 x 2400 DPI and over 50 levels of gradation. Another important specification for inkjet printers is ink drop size, typically measured in picoliters. The smaller the number, the more ink per square inch can be placed on the paper. The more ink, the more accurate and lifelike the color of the print.'

Searching for a Decent Scanner?

Fri, 09 Sep 2005 00:00:00 EDT

My little sister's scanner is acting up, so she's in the market for a new one. However, the software she wishes to use it with (some funkadelic 'music OCR' thing that lets you scan sheet music and transforms it automagically into MIDI files) claims that it doesn't work too well with HP scanners. And, truth be told, I've never known much about which scanners are good and which are crap. So, which scanners lately are decent? Which are crap? I know that DPI matters very little (just like it does in printers)-- it's quality that matters. Could the SlashDot community provide some info on which scanners (some from HP and some not from HP) are decent? Are there any quasi-reputable sites (a la Tom's Hardware?) that have reviews on such things?
