The xargs command may be one that many Linux users don’t know, but it’s also one that can save a lot of time and trouble on the command line. In a similar fashion, if you need to have the contents of a simple file show up on a single line, basically flattening the file, xargs will comply with your wishes. xargs Hello, World!
At Linux Academy, we continually invest in updating our training content. Linux Academy builds hands-on labs in a way that no other training provider does. For example, in Azure, if a learner is expected to learn how to troubleshoot a network setup, should the learner first set up the network in a broken fashion?
In what has been a fairly classic “yak shaving” exercise, I’ve been working on getting Ubuntu 15.10 “Wily Werewolf” running with Vagrant so that I can perform some testing with some other technologies that need a Linux kernel version of at least 4.2 network 'private_network' , ip: server [ 'ip_addr' ]. which comes with Ubuntu 15.10
I should try to find projects that are related and that support one another in some fashion. Reinforce base Linux knowledge. I’ll be focusing on Red Hat Enterprise Linux (RHEL) and RHEL variants, since that seems to be what’s most commonly found in enterprise deployments today. Mid-Year Project Update.
However, for the purposes of this series, I’ll limit the discussion to focus on how one would integrate VMware NSX with OpenStack via the OpenStack Neutron (formerly “Quantum”) project, which provides virtual networking functionality for OpenStack-based clouds.
Networking. Matt Oswalt has a great post on the need for networking professionals to learn basic scripting skills—something he (rightfully) distinguishes from programming as a full-time occupation. Further, he follows that up with a post on how automation is more than just configuration management ; it’s about network services.
In this post, I’m going to provide a quick introduction to OpenStack Heat, the orchestration service that allows you to spin up multiple instances, logical networks, and other cloud services in an automated fashion. The first resource defined is a logical network, defined as type OS::Neutron::Net.
Networking. I enjoyed Dave McCrory’s series on the future of the network (see part 1 , part 2 , part 3 , and part 4 —part 5 hadn’t gone live yet when I published this). Michael Kashin has a handy little tool that functions like ssh-copy-id on servers, but for network devices (leveraging Netmiko). In any case, enjoy!

Any Docker hosts you’re running must have Docker configured to listen on a network-accessible socket. I mentioned at the start of this post that I’d provide some comparison to other methods for deploying containers in an automated fashion. Interoperability Virtualization Automation Docker Linux OpenStack'
Platform9 was launched by former VMware veterans with the goal of making it easy for companies to consume their existing infrastructure in an agile, cloud-like fashion. Networking support is also limited; in the initial release, Platform9 will look for Linux bridges with matching names in order to stitch together networks.

Company employees managed information technology resources (compute, storage, network) and companies tightly controlled their data in facilities they managed. Many business processes are now expected to be dynamically executed in a parallel fashion (Agile business, Social Media Customer Service).
Networking. Lindsay Hill walks through using Telegraf, InfluxDB, and Grafana to monitor network statistics. Via Ivan Pepelnjak, I found this article by Diane Patton at Cumulus Networks talking about container network designs. Christian Kellner talks about work done on Thunderbolt 3 security levels for GNU/Linux.
By default, the Docker Engine on CentOS Atomic Host listens only to a local UNIX socket, and is not accessible over the network. I could , therefore, simply modify /etc/sysconfig/docker to make it listen on a network socket. So, I set out with an instance of CentOS Atomic Host and the Docker systemd docs to see what I could do.
If I were to still be in the business of administering servers, I’d be a Windows expert and feel comfortable managing Linux appliances within the environment. Most Linux admins wouldn’t have too much of a problem installing the solution. I believe I’m of the same ilk of the typical traditional VMware enterprise sysadmin.
Mayhem is not a box that plugs into the network. Today, it supports x86, x64, and ARM on Linux, as well as compiled languages,” Brumley shares. Walker and Brumley’s fashion sense captivates audiences. This is a decision made after seeing tremendous market validation for this capability. It is a high-tech solution.
Fisher sets the stage for people interacting with multiple devices, and devices that are highly mobile, supported by software and services delivered over a ubiquitous network connection. General Hardware IDF2013 Linux Microsoft Windows' He then introduces Hermann Eul. Similar Posts: IDF 2012 Keynote, Day 1. VMworld 2012 Keynote, Day 2.
At the same time, Apple is explicitly and purposefully excluding cloud gaming platforms that could bring the kinds of games that require a dedicated console or PC to those same gamers’ phones — by using the iPhone or iPad’s screen and network connection as mere conduits for a cloud gaming server instead.

FOX: Roberts: You basically have to understand how computer networks work, how avionics systems work, and then be able to translate communicate between those systems We've primarily focused on physically being in the airplane and hooking up to inflight entertainment. He wasn’t just some stunt hacker. I can join in, I can follow along.
I like to think of it this way: The cloud is a grouping of resources (compute, storage, network) that are available to be used in a manner that makes them both highly available and scalable, either up or down, as needed. The post Kubernetes and the Cloud appeared first on Linux Academy Blog.
CODEN: Basically, the fundamental issue is look at that early Unix and Linux operating systems that were providing these very basic services that are still the the only things we really need from the operating system today. It's every bit as fast as Linux. You can go to dbos-project.github.io But we did get a license. CODEN: Exactly.
