Getting Started: Tower Installer

Welcome to the first in our series of blog posts for Getting Started with Ansible Tower. This series covers basic installation and functions of Tower and an overview of how to use Tower to implement IT automation.

To get started with Tower, you must first learn to install and stand up a single host. Future posts will cover other types of configurations, such as a redundant installation with an external database. For this post, we’ll be highlighting RHEL 7 and Ubuntu LTS. 

Install Tower in 4 Simple Steps:

Run these steps as root (su -).

1. Download the latest Tower edition

If you haven’t already, visit this link to the trial page to have a download link sent to you. If you would like, our AMIs for AWS and our vagrant image are found there as well. If you have network restrictions, contact Ansible Sales and they can send you the bundled installer.

Note: We are currently working on a bundled installer for Ubuntu LTS, so the standard installer will install for Ubuntu.

2. Unpack the file (tar xzvf towerlatest)

 
$ tar xzvf towerlatest
ansible-tower-setup-3.1.0/
ansible-tower-setup-3.1.0/group_vars/
ansible-tower-setup-3.1.0/group_vars/all
...

-tar xzvf towerbundlelatest

 
$ tar xzvf  Continue reading

So whats next?

I’ve had a little time readjusting after my exam and I’ve given some thought on what to keep me busy next.

Basically I have 3 projects to keep me busy for the next foreseeable future.

1) CCNA-Wireless
My boss came to me a week ago and tasked me with this. He was very humble about it, which was amusing. I will be allocated some time from my normal work projects to study for the exam, which is really helpful. Fortunally some of my CCDE study friends are also going for this exam, so I wont be going down the road alone on this one either.
Im actually quite positive about this as its a technology area I have not really paid much attention to and its very different in what im used to. A shakeup is good every now and then

2) The IOS-XR Specialist exam
This is one I have been looking quite forward to for some time. Its basically an exam about all things IOS-XR and the platforms that supports it. I tried studying for this before I decided to go down the CCDE path, so it will be nice to pick back up.

3) Work on improving Continue reading

The Rise of Flash Native Cache

Burst buffers are growing up—and growing out of the traditional realm of large-scale supercomputers, where they were devised primarily to solve the problems of failure at scale.

As we described in an interview with the creator of the burst buffer concept, Los Alamos National Lab’s Gary Grider, the “simple” problem of checkpointing and restarting a massive system after a crash with a fast caching layer would be more important as system sizes expanded—but the same approach could also extend to application acceleration. As the notion of burst buffers expanded beyond HPC, companies like EMC/NetApp, Cray, and DataDirect Networks (DDN) …

The Rise of Flash Native Cache was written by Nicole Hemsoth at The Next Platform.

Third-party releases ‘nano-patch’ for Microsoft zero day bug

The delay in last month's Patch Tuesday fixes has caused considerable angst given there were several known problems, including two disclosed by Google.Microsoft is on track, as far as we know, for a patch release next week, but one company isn't waiting. It has issued its own fix for a minor bug.A U.K. security company called ACROS Security has released what they call their first "nano-patch" for CVE-2017-0038, a bug in EMF image format parsing logic that does not adequately check image dimensions specified in the image file being parsed against the amount of pixels in the file.If image dimensions are large enough, the parser is tricked into reading memory contents beyond the memory-mapped EMF file being parsed. An attacker could use this vulnerability to steal sensitive data in memory or as an aid in other exploits when ASLR needs to be defeated.To read this article in full or to leave a comment, please click here

Microsoft’s Windows Server OS runs on ARM, with help from Qualcomm

Microsoft has warmed up to Qualcomm to make a Windows 10 PC based on its ARM chip, and now the companies are bringing Windows Server OS to ARM. For the first time ever, Microsoft is expected to show the Windows Server OS running on an ARM server. The server runs on Qualcomm's Centriq 2400, an ARM-based chip designed for cloud servers. The server is being shown at the Open Project Compute Summit being held in Santa Clara, California, on Wednesday and Thursday.The ARM-based Windows Server hardware is for Microsoft's internal use. No information was shared on when Windows Server would be available for ARM servers. The ARM-based Windows Server hardware is for Microsoft's internal use.

Apple, Cisco, Microsoft and Samsung react to CIA targeting their products

From the trove of CIA documents dumped by WikiLeaks, we’ve heard a lot about attacks the agency could pull off against TVs and smartphones. Some of companies with targeted products have issued their initial responses.October 2014 notes discuss the CIA’s Embedded Devices Branch (EDB) and what it should target. For the “really non-technical,” the CIA would define “embedded systems” as “The Things in the Internet of Things.” But the fact that the CIA intended to exploit IoT should not surprise anyone, considering that in 2012, then-CIA Director David Petraeus said the CIA “cannot wait to spy on you” through your smart internet-connected devices.To read this article in full or to leave a comment, please click here

An AMP validator you can cURL

Cloudflare has been a long time supporter of AMP, an open-source markup language 1.5 billion web pages are using to accelerate their mobile web performance. Cloudflare runs Ampersand, the only alternative to Google’s AMP cache, and earlier this year we launched Accelerated Mobile Links, a way for sites on Cloudflare to open external links on their site in AMP format, as well as Firebolt, leveraging AMP to speed up ad performance.

One of the biggest challenges developers face in converting their web pages to AMP is testing their AMP pages for valid AMP syntax before deploying. It's not enough to make the templates work at dev time, you also need to validate individual pages before they’re published. Imagine, for example, a publishing company where content creators who are unfamiliar with AMP are modifying pages. Because the AMP markup language is so strict, one person adding an interactive element to a page can all of a sudden break the AMP formatting and stop the page from validating.

We wanted to make it as easy as possible to move webpages and sites to AMP so we built an AMP linter API for developers to check that their Continue reading

Review: JAM Voice speaker adds Amazon Alexa support

Amazon offers several options for people who want to experience the Echo/Alexa voice-controlled assistance technology. For $180 (or $130 if you buy the Amazon Tap) you can buy the full Amazon Echo speaker system; if you already own a Bluetooth speaker system you can get the $50 Echo Dot.If you’re not down with the Amazon hardware, you have another third-party option. The JAM Voice ($50, via Amazon) from JAM Audio is a Wi-Fi and Bluetooth speaker that includes Amazon Alexa Voice Service integration. The tiny speaker offers up to four hours of play time and recharges via USB cable (power outlet adapter not included).The speaker sets up via the JAM Wi-Fi app, letting you connect the speaker to your existing Wi-Fi network (you need Internet connectivity in order to use the Alexa voice services). If you don’t want to utilize that option, you can connect via Bluetooth like every other portable Bluetooth speaker. The JAM Voice also integrates with JAM Audio’s other Wi-Fi speaker systems (the Rhythm and Symphony) to give you multi-room audio.To read this article in full or to leave a comment, please click here

IDG Contributor Network: ScyllaDB another contender to the open source NoSQL database crown

The world of the database is one of those areas that sees lots of people obsessing over details that to outside observers would seem trivial. Graph, NoSQL, SQL, distributed—so many choices.So, when ScyllaDB told me about a funding round that they’d raised and their stated intention to replace Apache Cassandra, I was interested—if slightly skeptical. Not skeptical because of anything I know about ScyllaDB per se, but simply because of the busy-ness of the space.+ Also on Network World: Google’s new cloud service is a unique take on a database + The launch only a couple of weeks ago of Google’s Cloud Spanner database, an offering developed from the internal tools that Google itself uses, certainly upped the database ante. Google’s assertion that Cloud Spanner gives users all the benefits of both regular relational and NoSQL databases put all other database offerings on guard.To read this article in full or to leave a comment, please click here

IT professionals think Apple devices are easier to manage, according to new survey

A recent survey has found that your IT department thinks a Mac is more manageable than a PC or Chromebook.According to a survey of IT professionals, Macs and iOS devices are easier to manage when it comes to security, device configuration, software deployment, and support. Of those surveyed, 62 percent said the Mac is as easy or easier to deploy than PC, and 93 percent said it’s as easy or easier to deploy an iPhone or iPad over another device.While most IT professionals found Apple’s products easier to manage overall, that was not the case when it comes to Mac integration. Only 36 percent of IT professionals claimed that it was easy or easier to integrate Macs into other environments. The survey is based on responses from 300 IT professionals and was commissioned by Jamf, the software management firm that focuses solely on Apple devices.To read this article in full or to leave a comment, please click here

What’s the value in attack attribution?

For those who pursue forensic analysis with the hope of identifying and prosecuting an attacker, they likely will find that the time spent on attack attribution is fruitless.If, however, they are looking to use what they gain through attack attribution to inform their overall security procedures from prevention to response, the effort yields valuable results.Many experts in the industry have questioned whether there is any value to attribution. SafeBreach CTO & co-founder Itzik Kotler said, "The only interesting aspect in attribution itself is to classify and put information in a box and use it over and over again."Kolter offered a hypothetical in which right now CNN gets hacked by the Chinese. "That someone can or cannot attribute it to the Chinese doesn't matter. It does matter if we can say we think this is from China," Kolter said.To read this article in full or to leave a comment, please click here

Smackdown: Office 365 vs. G Suite collaboration

Ever since I can remember, Silicon Valley has been enamored with the idea of group editing of documents. Very little good writing gets done that way, of course.
