Linux Network Interface Configuration With udev

I’m recently been running down (or is it through) the Linux, systemd, networkd, udevd rabbit hole at full pelt and thought perhaps now was a good time to come up for some air and to share what I’ve learned so far. I could (and have elsewhere) written long essays on why Linux makes an excellent network […]

Legacy telcos make peace with Internet services in Africa

Companies providing audiovisual content and apps over the Internet are becoming increasingly influential in Africa, to the point where traditional telecom operators are essentially being forced to accommodate them.A growing number of telecom company executives themselves believe that so-called over-the-top (OTT) service providers, delivering apps and multimedia content over the Web, will only increase in influence, according to an Ovum survey.The Digital Africa survey, presented at Ovum’s recent Connecting West Africa conference in Dakar, found that 35 percent of telecom company executives polled believed that OTT service providers will be very important in five years, compared to only 18 percent who think that they are very influential today.To read this article in full or to leave a comment, please click here

Some users will ‘kick and scream’ at paying with slower chip cards

Major U.S. banks have been rolling out new, secure smart chip debit and credit cards for months, but the real end-user impact hasn't yet been felt.Some experts say typical consumers will get confused and may even balk when first attempting to use these new "pin and chip" smart cards. As a result, customers may choose to rely on the less-secure magnetic stripe also on the new cards for in-store purchases.MORE: 10 mobile startups to watch Or, customers could even turn to mobile wallet alternatives, like Apple Pay or the coming Android Pay, and skip the credit and debit card experience altogether.To read this article in full or to leave a comment, please click here

Solving the “jabber-config.xml” File Mystery

The jabber-config.xml file is an essential piece of configuration for the Jabber client. Sure, the client has the ability to operate just fine without this file. Video calling, deskphone control, instant messaging, etc. all work flawlessly. However, if you need to add any additional options, policies, or directory integrations, the jabber-config.xml file becomes necessary. Within the realm of the CCIE Collaboration certification, we are specifically concerned about two different configurations: UDS Directory Integration and SIP URI Dialing.

User Data Service (UDS) simply put, is the name for the End User database within Cisco Unified Communications Manager (CUCM). It contains all relevant information about that user, as would any other directory. UDS, however, is not enabled by default on the Jabber client. In fact, Jabber is geared towards integration with an LDAP source “out of the box”. This means that we must instruct the Jabber client to use UDS if we would like to be able to search the CUCM database to communicate with other users. Since this will have to be done by using the jabber-config.xml file, we must first determine how to create it. Thankfully, the Cisco documentation does not disappoint in this regard.

Juniper, Ruckus join hands with an eye on mobile growth

The alliance between Juniper Networks and Ruckus Wireless announced on Tuesday underscores the importance of Wi-Fi in enterprises, where employees increasingly work and access cloud applications on mobile devices.Juniper and Ruckus say they’re joining forces to build integrated wired and wireless infrastructures while keeping their technologies open and standards-based. The companies focused on enterprises in announcing the partnership, but they will also integrate technologies for service-provider networks, Ruckus Vice President of Corporate Marketing David Callisch said.As Wi-Fi gets faster and more workers use laptops and other portable devices, more enterprises see wireless as a real alternative to traditional ethernet LANs, said Gartner analyst Tim Zimmerman. Some networks based on IEEE 802.11ac theoretically can deliver more speed than Gigabit ethernet, and the second wave of that technology now emerging will offer more than 6Gbps on the top end.To read this article in full or to leave a comment, please click here

Apple takes a greater role in Bluetooth development

Apple will be playing a larger role in the development of Bluetooth as the company pushes into wearable technology, home automation and more.The Bluetooth Special Interest Group, which oversees the development of the wireless communication standard, announced Tuesday that Apple has become a “promoter member” of the group, giving the company new power to guide Bluetooth’s development. Promoter members are given a continual seat on the group’s board of directors, and are also the only membership class that can vote on its corporate matters.Apple has been an associate board member of the group since 2011, and the company’s senior wireless architect, Joakim Linde. currently serves as the board’s secretary. In the past, Apple’s board membership was term limited. The current promoter members—Ericsson, Intel, Lenovo, Microsoft, Nokia, and Toshiba—voted unanimously to have Apple join their ranks.To read this article in full or to leave a comment, please click here

Instagram gets more Twitter-y with trending photos

Instagram, the popular app for sharing photos with friends, is broadening the reach of those photos.On Tuesday, the Facebook-owned app significantly expanded its service with new features around search and trending topics. The changes are aimed at letting users discover photos and videos related to popular events and places, and letting users more easily find photos taken in particular places.The changes are aimed at making Instagram not just an app to see friends’ photos, but an app for seeing other people’s photos related to local or global events. The changes put Instagram’s app more squarely in competition with Twitter, already known for its real-time feed of tweets around events, including photos and videos.To read this article in full or to leave a comment, please click here

Liveblog: DockerCon 2015 Day 2 General Session

This is a liveblog from the day 2 general session at DockerCon 2015. I was running late from some early morning meetings (sorry folks), so I wasn’t able to catch the first part of the general session (about the first 15 minutes or so). Here’s what I was able to capture.

Chris Buckley, Director of DevOps at Business Insider, took the stage to provide an overview of how Business Insider (BI) started using Docker. Buckley provides some “lessons learned”:

  1. Building for production first was grandiose was misguided.
  2. Porting it back to development wasn’t the right approach.

This led BI to Fig (now Docker Compose), which led to a decrease in the time it took to get a development environment up and running. With the combination of Vagrant and Docker, BI was able to reduce that to just a couple of hours. When BI revisited production apps, they turned to use Upstart/SysV scripts for containers, but this wasn’t quite the right fit. BI turned back to Puppet, building a parameterized Puppet class to create containers, links, set environment options, and define dependencies on other containers/services starting first.

Before Docker, the workflow was developers to GitHub to Jenkins, which then pushed to Continue reading

Adobe patches zero-day Flash Player flaw used in targeted attacks

Adobe Systems released an emergency security update for Flash Player Tuesday to fix a critical vulnerability that has been exploited by a China-based cyberespionage group.Over the past several weeks, a hacker group identified as APT3 by security firm FireEye has used the vulnerability to attack organizations from the aerospace, defense, construction, engineering, technology, telecommunications and transportation industries.The hacking group targeted the companies with generic phishing emails that contained a link to a compromised server, researchers from FireEye said in a blog post Tuesday. The server used JavaScript code to profile potential victims and then served the Flash exploit to the ones meeting attackers’ criteria, the company said.To read this article in full or to leave a comment, please click here

IT pros blast Google over Android’s refusal to play nice with IPv6

Two trains made of fiber, copper and code are on a collision course, as the widespread popularity of Android devices and the general move to IPv6 has put some businesses in a tough position, thanks to Android’s lack of support for a central component in the newer standard. DHCPv6 is an outgrowth of the DHCP protocol used in the older IPv4 standard – it’s an acronym for “dynamic host configuration protocol,” and is a key building block of network management. Nevertheless, Google’s wildly popular Android devices – which accounted for 78% of all smartphones shipped worldwide in the first quarter of this year – don’t support DHCPv6 for address assignment.To read this article in full or to leave a comment, please click here
