"The Linux Foundation announced the LFCS (Linux Foundation Certified Sysadmin) certification, a new program that aims at helping individuals all over the world to get certified in basic to intermediate system administration tasks for Linux systems. This includes supporting running systems and services, along with first-hand troubleshooting and analysis, and smart decision-making to escalate issues to engineering teams.

Jolla Crowdfunds Its First Tablet
by Peter Reutemann 19 Nov '14

19 Nov '14

'Jolla is another rising star in the tech world, having recently expanded its smartphone sales into more countries across the globe. Jolla's Sailfish OS is based on the Linux kernel, and considered by many to be a direct successor to Nokia and Intel's MeeGo and the N9 mobile phone. Its software is based on the open-sourced components of MeeGo. Now, the company is ready to start production of its first tablet. They're crowdfunding it, and they blew past their $380,000 goal in about two hours. The tablet has a 7.9-inch screen with a resolution of 2048 x 1536. It's powered by a 1.8GHz 64-bit quad-core Intel processor, comes with a 32GB of storage, an SD card slot, 2GB of RAM and a 5MP rear camera. Judging by its size, we can see this will rival the iPad Mini the new Nokia N1. While there aren't too many Sailfish-specific apps available, as with the phone, Jolla's tablet will be compatible with Android apps.' -- source: http://linux.slashdot.org/story/14/11/19/1343250 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Launching 2015: a New Certificate Authority To Encrypt the Entire Web
by Peter Reutemann 18 Nov '14

18 Nov '14

"Today EFF, Mozilla, Cisco, and Akamai announced a forthcoming project called Let's Encrypt. Let's Encrypt will be a certificate authority that issues free certificates to any website, using automated protocols (demo video here). Launching in summer 2015, we believe this will be the missing piece that deprecates the woefully insecure HTTP protocol in favor of HTTPS." -- source: http://it.slashdot.org/story/14/11/18/1830229 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Crowdfunded Linux Voice Magazine Releases First Issue CC-BY-SA
by Peter Reutemann 18 Nov '14

18 Nov '14

"Linux Voice, the crowdfunded GNU/Linux magazine that Slashdot has covered previously, had two goals at its launch: to give 50% of its profits back to the community after one year, and release each issue's contents under the Creative Commons after nine months. Well, it's been nine months since issue 1, so the whole thing is now online and free to share. Readers and supporters have also made audio versions of articles, for listening to on the commute to work." -- source: http://linux.slashdot.org/story/14/11/18/1636234 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

Turning a Rasberry Pi into a Tor Gateway with Sphirewall
by Michael Lawson 17 Nov '14

17 Nov '14

Earlier this month Sphirewall released support for Tor as a transparent gateway, we thought it would be neat to get it running on the Pi and show it of a little bit. Half shameless plug, half interesting use case for Sphirewall and a Pi. http://sphirewall.net/blog.html?post_id=2 (Also 100% kiwi ;)) -- Michael Lawson

Fedora Looks To Make /usr World-Readable
by Peter Reutemann 17 Nov '14

17 Nov '14

"Fedora developers are looking at requiring all files that be placed in /usr world-readable. Developers are seeking a mandate that all Fedora packages must not install any non-world-readable files within /usr. Right now some Fedora packages do not honor this and restrict permissions to certain files/directories. Stakeholders are after making the user directory world-readable since containerized copies of Fedora can have the directory bind-mounted into the container, support for virtualization use-cases, and for better systemd handling.

Longtime Debian Developer Tollef Fog Heen Resigns From Systemd Maintainer Team
by Peter Reutemann 17 Nov '14

17 Nov '14

'Debian developer Tollef Fog Heen submitted his resignation to the Debian Systemd package maintainers team mailing list today (Sun. Nov. 16th, 2014). In his brief post, he praises the team, but claims that he cannot continue to contribute due to the "load of continued attacks...becoming just too much." Presumably, he is referring to the heated and, at times, even vitriolic criticism of Debian's adoption of Systemd as the default init system for its upcoming Jessie release from commenters inside and outside of the Debian community. Currently, it is not known if Tollef will cease contributing to Debian altogether. A message from his twitter feed indicates that he may blog about his departure in the near future.' -- source: http://linux.slashdot.org/story/14/11/16/2142244 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

81% of Tor Users Can Be De-anonymized By Analysing Router Information
by Peter Reutemann 15 Nov '14

15 Nov '14

"A former researcher at Columbia University's Network Security Lab has conducted research since 2008 indicating that traffic flow software included in network routers, notably Cisco's 'Netflow' package, can be exploited to deanonymize 81.4% of Tor clients. Professor Sambuddho Chakravarty, currently researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology, uses a technique which injects a repeating traffic pattern into the TCP connection associated with an exit node, and then compares subsequent aberrations in network timing with the traffic flow records generated by Netflow (or equivalent packages from other router manufacturers) to individuate the 'victim' client. In laboratory conditions the success rate of this traffic analysis attack is 100%, with network noise and variations reducing efficiency to 81% in a live Tor environment. Chakravarty says: 'it is not even essential to be a global adversary to launch such traffic analysis attacks. A powerful, yet non- global adversary could use traffic analysis methods [] to determine the various relays participating in a Tor circuit and directly monitor the traffic entering the entry node of the victim connection.'" -- source: http://yro.slashdot.org/story/14/11/14/1851245 Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
