Linux and Multiple Internet Uplinks: a New Tool 64

Posted by Soulskill
from the fault-tolerance-for-all dept.
New submitter Alessandro Zarrilli writes: Linux has been able do multipath routing for a long time: it means being able to have routes with multiple gateways and to use them in a (weighted) round-robin fashion. But Linux is missing a tool to actively monitor the state of internet uplinks and change the routing accordingly. Without it, from a LAN perspective, it's like having a RAID-0: just one uplink goes down and all of your LAN-to-WAN traffic goes down too. Documentation and examples on the subject are lacking; existing solutions are few and deeply integrated in firewall/routing specific distributions. To address these issues, a new standalone tool was just released: Fault Tolerant Router. It also includes a complete (iptables + ip policy routing) configuration generator.

Google Taking Over New TLDs 185

bobo the hobo writes: In the corner of the internet where people care about DNS, there is a bit of an uproar at Google's application for over a hundred new top-level domains, including .dev, .lol, .app, .blog, .cloud and .search. Their application includes statements such as: "By contrast, our application for the .blog TLD describes a new way of automatically linking new second level domains to blogs on our Blogger platform – this approach eliminates the need for any technical configuration on the part of the user and thus makes the domain name more user friendly." They also mention limiting usage of .dev to Google only: "Second-level domain names within the proposed gTLD are intended for registration and use by Google only, and domain names under the new gTLD will not be available to the general public for purchase, sale, or registration. As such, [Google's shell company] intends to apply for an exemption to the ICANN Registry Operator Code of Conduct as Google is intended to be the sole registrar and registrant."

UK Scientists Claim 1Tbps Data Speed Via Experimental 5G Technology 71

Posted by timothy
from the hefty-overages dept.
Mark.JUK writes A team of Scientists working at the University of Surrey in England claim to have achieved, via an experimental lab test, performance of 1Tbps (Terabit per second) over their candidate for a future 5G Mobile Broadband technology. Sadly the specifics of the test are somewhat unclear, although it's claimed that the performance was delivered by using 100MHz of radio spectrum bandwidth over a distance of 100 metres. The team, which forms part of the UK Government's 5G Innovation Centre, is supported by most of the country's major mobile operators as well as BT, Samsung, Fujitsu, Huawei, the BBC and various other big names in telecoms, media and mobile infrastructure. Apparently the plan is to take the technology outside of the lab for testing between 2016 and 2017, which would be followed by a public demo in early 2018. In the meantime 5G solutions are still being developed, with most in the early experimental stages, by various different teams around the world. Few anticipate a commercial deployment happening before 2020 and we're still a long way from even defining the necessary standard.

Unfortunately, now it's TMobile that's having trouble tracking data; it seems to be related to the rollout of their new DataStash promotion. Just like AT&T, they're blaming the customer. Here are the ten lies T-Mobile told me about my data usage today."

An anonymous reader writes: Mark Nottingham, chair of the IETF HTTP working group, has announced that the HTTP/2 specification is done. It's on its way to the RFC Editor, along with the HPACK specification, where it'll be cleaned up and published. "The new standard brings a number of benefits to one of the Web's core technologies, such as faster page loads, longer-lived connections, more items arriving sooner and server push. HTTP/2 uses the same HTTP APIs that developers are familiar with, but offers a number of new features they can adopt. One notable change is that HTTP requests will be 'cheaper' to make. ... With HTTP/2, a new multiplexing feature allows lots of requests to be delivered at the same time, so the page load isn't blocked." Here's the HTTP/2 FAQ, and we recently talked about some common criticisms of the spec.

from the oops-and-darnit dept.
An anonymous reader writes A number of Netgear home wireless routers sport a vulnerability that can be misused by unauthenticated attackers [here's the report at seclists.org] to obtain the administrator password, device serial number, WLAN details, and various details regarding clients connected to the device, claims systems/network engineer Peter Adkins. The vulnerability is found in the embedded SOAP service, which is a service that interacts with the Netgear Genie application that allows users to control (change WLAN credentials, SSIDs, parental control settings, etc.) their routers via their smartphones or computers.

Removing Libsystemd0 From a Live-running Debian System 755

Posted by samzenpus
from the taking-sides dept.
lkcl writes The introduction of systemd has unilaterally created a polarization of the GNU/Linux community that is remarkably similar to the monopolistic power position wielded by Microsoft in the late 1990s. Choices were stark: use Windows (with SMB/CIFS Services), or use UNIX (with NFS and NIS). Only the introduction of fully-compatible reverse-engineered NT Domains services corrected the situation. Instructions on how to remove systemd include dire warnings that "all dependent packages will be removed", rendering a normal Debian Desktop system flat-out impossible to achieve. It was therefore necessary to demonstrate that it is actually possible to run a Debian Desktop GUI system (albeit an unusual one: fvwm) with libsystemd0 removed. The reason for doing so: it doesn't matter how good systemd is believed to be or in fact actually is: the reason for removing it is, apart from the alarm at how extensive systemd is becoming (including interfering with firewall rules), it's the way that it's been introduced in a blatantly cavalier fashion as a polarized all-or-nothing option, forcing people to consider abandoning the GNU/Linux of their choice and to seriously consider using FreeBSD or any other distro that properly respects the Software Freedom principle of the right to choose what software to run. We aren't all "good at coding", or paid to work on Software Libre: that means that those people who are need to be much more responsible, and to start — finally — to listen to what people are saying. Developing a thick skin is a good way to abdicate responsibility and, as a result, place people into untenable positions.

Li-Fi-like System Pushes 100Gbps Within a Small Room 38

from the go-big-or-go-home dept.
An anonymous reader writes: Oxford University is [building] a system that takes light from the fiber, amplifies it, and beams it across a room to deliver data at more than 100 gigabits per second. ... The trick, of course, is getting the light beam exactly where it needs to go. An optical fiber makes for a target that's only 8 or 9 micrometers in diameter, after all. The team, which also included researchers from University College, London, accomplished this using so-called holographic beam steering at both the transmitter and receiver ends. These use an array of liquid crystals to create a programmable diffraction grating that reflects the light in the desired direction. ... With a 60-degree field of view, the team was able to transmit six different wavelengths, each at 37.4 Gb/s, for an aggregate bandwidth of 224 Gb/s (abstract). With a 36-degree field of view, they managed only three channels, for 112 Gb/s.

LinkedIn Restricts API Usage 69

Posted by samzenpus
from the keep-your-hands-off dept.
mpicpp points out LinkedIn's new API policy. "LinkedIn is restricting access to most of its application programming interfaces (APIs) to companies that have struck up partnerships with the social networking company. 'Over the past several years, we've seen some exciting applications from our developer community. While many delivered value back to our members and LinkedIn, not all have,' wrote Adam Trachtenberg, director of the LinkedIn developer network, explaining in a blog post the change in the company's API policy. Starting May 12, LinkedIn will only offer a handful of its APIs for general use, namely those that allow users and companies to post information about themselves on the service. After then, only companies that have enrolled in LinkedIn's partner program will have API access. Samsung, WeChat, and Evernote have already struck such partnerships. Currently, the social networking service offers a wide range of APIs, which allow third-party programs to draw content from, and place content into, LinkedIn. APIs have been seen as an additional channel for businesses to interact with their users and partners. A few companies, however, have recently scaled back access to APIs, which provide the programmatic ability to access a company's services and data. Netflix shut its public API channel in November, preferring to channel its user information through a small number of partners. ESPN also disabled public access to its APIs in December. LinkedIn's move is evidence of how the business use of APIs are evolving, said John Musser, founder and CEO at API Science, which offers an API performance testing service."

EFF: Hundreds of S. Carolina Prisoners Sent To Solitary For Social Media Use 176

Posted by timothy
from the don't-you-have-enough-friends-already? dept.
According to the EFF's Deep LInks, Through a request under South Carolina’s Freedom of Information Act, EFF found that, over the last three years, prison officials have brought more than 400 hundred disciplinary cases for "social networking" — almost always for using Facebook. The offenses come with heavy penalties, such as years in solitary confinement and deprivation of virtually all privileges, including visitation and telephone access. In 16 cases, inmates were sentenced to more than a decade in what’s called disciplinary detention, with at least one inmate receiving more than 37 years in isolation. ... The sentences are so long because SCDC issues a separate Level 1 violation for each day that an inmate accesses a social network. An inmate who posts five status updates over five days, would receive five separate Level 1 violations, while an inmate who posted 100 updates in one day would receive only one. In other words, if a South Carolina inmate caused a riot, took three hostages, murdered them, stole their clothes, and then escaped, he could still wind up with fewer Level 1 offenses than an inmate who updated Facebook every day for two weeks.

Polymers Brighten Hopes For Visible Light Communication 64

Posted by timothy
from the hope-is-measures-in-photons dept.
ckwu writes Today nearly all computers, tablets, and smartphones have Wi-Fi capabilities, receiving and transmitting data over a range of radio frequencies. But a burgeoning technology known as visible light communication could someday carry those data in the same light that illuminates a room. Now a tag team of semiconducting organic polymers is bringing that dream one step closer. When excited with a blue LED, the polymer pair helps to create white light that can be rapidly switched on and off to encode information. A proof-of-principle device using the polymers sent data at 350 Mbps over a distance of 5 cm with minimal errors, a rate 35 times faster than a commercially available phosphor used for blue-light color conversion.

Demonii Tracker Tops 30 Million Connected Peers 36

Posted by timothy
from the not-every-large-number-is-a-barrier dept.
An anonymous reader writes Demonii is the tracker behind the scenes for many BitTorrent sites serving pirated content. This week the tracker broke through the barrier of 30 million connected peers, handling no less than 2 billion connections per day. In other words, the scale of operation has become massive. TorrentFreak interviewed an operator of the site, and it was revealed that the tracker runs smoothly on just three dedicated servers, communicating at 180 Mb/s while serving 4 million torrents. Some people have argued that trackers are obsolete in the first place, as DHT and PEX allow peers to share the same information among each other, but Demonii's operator reminds that having trackers speeds up the initial peer finding significantly. In any case, Demonii is not going away anytime soon. The tracker is already on its way to another milestone. The 40 million peer milestone will probably come into view later this year, but first there are a trillion more connections to process.

Automakers Move Toward OTA Software Upgrades 157

Posted by Soulskill
from the granted-features-like-a-wizard dept.
Lucas123 writes: While some carmakers today offer over-the-air software upgrades to navigation maps and infotainment head units, Tesla became the first last week to perform a powertrain upgrade overnight. But as the industry begins adopting internal vehicle bus standards with greater bandwidth and more robust security, experts believe vehicle owners will no longer be required to visit dealerships or perform downloads to USB sticks. IHS predicts that in the next three to five years, most, if not all automakers, will offer fully fledged OTA software-enabled platforms that encompass upgrades to every vehicle system — from infotainment, safety, comfort, and powertrain. First, however, carmakers must deploy more open OS platforms, remove hardened firewalls between vehicle ECUs, and deploy networking topologies such as Ethernet, with proven security.

Does Showing a Horrific Video Serve a Legitimate Journalistic Purpose? 645

Posted by Soulskill
from the sensitive-topics dept.
HughPickens.com writes: Erik Wemple writes at the Washington Post that Fox News recently took the controversial step of posting a horrific 22-minute video online that shows Jordanian pilot Lt. Muath al-Kaseasbeh being burned to death. Fox warned internet users that the presentation features "extremely graphic video." "After careful consideration, we decided that giving readers of FoxNews.com the option to see for themselves the barbarity of ISIS outweighed legitimate concerns about the graphic nature of the video," said Fox executive John Moody. "Online users can choose to view or not view this disturbing content."

But Fox's decision drew condemnation from some terrorism experts. "[Fox News] are literally — literally — working for al-Qaida and ISIS's media arm," said Malcolm Nance. "They might as well start sending them royalty checks." YouTube removed a link to the video a few hours after it was posted, and a spokesperson for Facebook told the Guardian that if anyone posted the video to the social networking site it would be taken down. CNN explained that it wouldn't surface any of the disturbing images because they were gruesome and constituted propaganda that the network didn't want to distribute. "Does posting this video advance the aims of this terror group or hinder its progress by laying bare its depravity?" writes Wemple. "Islamic State leaders may indeed delight in the distribution of the video — which could be helpful in converting extremists to its cause — but they may be mis-calibrating its impact. If the terrorists expected to intimidate the world with their display of barbarity, they may be disappointed with the reaction of Jordan, which is vowing 'strong, earth-shaking and decisive' retaliation."

New Fiber Optic Signal Processing Technique Doubles Communication Distance 59

Posted by Soulskill
from the still-can't-reach-the-moon dept.
hypnosec writes: Researchers at University College London (UCL) have demonstrated a new technique for fiber optic signal processing that doubles the distance at which data travels error-free through transatlantic sub-marine cables. The UCL research, published in Scientific Reports, has the potential to reduce the costs of long-distance optical fiber communications as signals wouldn't need to be electronically boosted during their journey, which is important when the cables are buried underground or at the bottom of the ocean. The study reports a new way of improving the transmission distance, by undoing the interactions that occur between different optical channels as they travel side-by-side over an optical cable. By eliminating the interactions between the optical channels, researchers increase distance signals can be transmitted error-free from 3190km to 5890km, which is the largest increase ever reported for this system architecture.

BT Unveils 1000Mbps Capable G.fast Broadband Rollout For the United Kingdom 132

Posted by timothy
from the gee-that's-fast dept.
Mark.JUK writes The national telecoms operator for the United Kingdom, BT, has today announced that it will begin a country-wide deployment of the next generation hybrid-fibre G.fast (ITU G.9701) broadband technology from 2016/17, with most homes being told to expect speeds of up to 500Mbps (Megabits per second) and a premium service offering 1000Mbps will also be available.

At present BT already covers most of the UK with hybrid Fibre-to-the-Cabinet (FTTC) technology, which delivers download speeds of up to 80Mbps by running a fibre optic cable to a local street cabinet and then using VDSL2 over the remaining copper line from the cabinet to homes. G.fast follows a similar principal, but it brings the fibre optic cable even closer to homes (often by installing smaller remote nodes on telegraph poles) and uses more radio spectrum (17-106MHz) over a shorter remaining run of copper cable (ideally less than 250 metres). The reliance upon copper cable means that the real-world speeds for some, such as those living furthest away from the remote nodes, will probably struggle to match up to BT's claims. Nevertheless many telecoms operators see this as being a more cost effective approach to broadband than deploying a pure fibre optic / Fibre-to-the-Home (FTTH) network.
