En el Debian Bug report logs – #756479 podremos ver como se han deshabilitado los comandos desde el servidor (compilando el nrpe sin –enable-command-args con argumentos tan sólidos como “hay gente que los usa mal“. Vamos a ver cómo usar un PPA alternativo para saltarnos la restricción de Debian
Podemos usar el PPA dontblamenrpe:
add-apt-repository ppa:dontblamenrpe/ppa
Configuramos preferencia del PPA sobre el paquete de la distribución:
cat <<EOF > /etc/apt/preferences.d/nrpe_dontblamenrpe Package: * Pin: release o=LP-PPA-dontblamenrpe Pin-Priority: 700 EOF
Podemos ver las prioridades mediante apt-cache policy:
root@ubuntu16:~# apt-cache policy nagios-nrpe-server
nagios-nrpe-server:
Installed: (none)
Candidate: 2.15-1ubuntu10
Version table:
2.15-1ubuntu10 700
700 http://ppa.launchpad.net/dontblamenrpe/ppa/ubuntu xenial/main amd64 Packages
100 /var/lib/dpkg/status
2.15-1ubuntu1 500
500 http://ad.archive.ubuntu.com/ubuntu xenial/main amd64 Packages
Actualizamos e instalamos:
apt-get update apt-get install nagios-nrpe-server
Una vez instalados ya dispondremos del binarion de nrpe con la opción enable-command-args habilitada
Vamos a ver cómo instalar las versiones 5.4, 5.5, 5.6 y 7.0 de PHP en Ubuntu 14.04
Primero deberemos tener instalado el siguiente paquete:
$ sudo apt-get install python-software-properties
Para PHP 5.4 usaremos el repositorio ppa:ondrej/php5-oldstable:
$ sudo add-apt-repository ppa:ondrej/php5-oldstable $ sudo apt-get update $ sudo apt-get install -y php5
Para PHP 5.5:
$ sudo add-apt-repository ppa:ondrej/php $ sudo apt-get update $ sudo apt-get install -y php5.5
Para PHP 5.6
$ sudo add-apt-repository ppa:ondrej/php $ sudo apt-get update $ sudo apt-get install -y php5.6
Finalmente, para PHP 7.0:
$ sudo add-apt-repository ppa:ondrej/php $ sudo apt-get update $ sudo apt-get install -y php7.0
For people who love security and open-source systems, Ubuntu is a favorite. According to the BuildWith website, there are 3,097,360 live websites using Ubuntu, which equates to 0.9% of the entire Internet. AskUbuntu forums reports that Ubuntu has 1-2% market share in most markets. Another interesting fact about Ubuntu from OMGUBUNTU survey is that Ubuntu […]

Microsoft has announced plans to simplify Big Data and widen its use through Azure.
In a blog post, T K Rengarajan, Microsoft’s corporate VP for Data Platforms, described how the expanded Microsoft Azure Data Lake Store, available in preview later this year, will provide a single repository that captures data of any size, type and speed without forcing changes to applications as data scales. In the store, data can be securely shared for collaboration and is accessible for processing and analytics from HDFS applications and tools.
Another new addition is Azure Data Lake Analytics, a service built on Apache YARN that dynamically scales, which Microsoft says will stop people being side tracked from work by needing to know about distributed architecture. This service, available in preview later this year, will include U-SQL, a language that unifies the benefits of SQL with the expressive power of user code. U-SQL’s scalable distributed querying is intended to help users analyse data in the store and across SQL Servers in Azure, Azure SQL Database and Azure SQL Data Warehouse.
Meanwhile, Microsoft has selected Ubuntu for its first Linux-based Azure offering. The Hadoop-based big data service offering, HDInsight, will run on Canonical’s open source browser Ubuntu.
Azure HDInsight uses a range of open source analytics engines including Hive, Spark, HBase and Storm. Microsoft says it is now on general release with a 99.9 per cent uptime service level agreement.
Meanwhile Azure Data Lake Tools for Visual Studio will provide an integrated development environment that aims to ‘dramatically’ simplify authoring, debugging and optimization for processing and analytics at any scale, according to Rengarajan. “Leading Hadoop applications that span security, governance, data preparation and analytics can be easily deployed from the Azure Marketplace on top of Azure Data Lake,” said Rengarajan.
Azure Data Lake removes the complexities of ingesting and storing all of your data while making it faster to get up and running with batch, streaming, and interactive analytics, said Rengarajan.
Krishnan will lead Canonical’s cloud efforts
Canonical has appointed former Microsoft exec Anand Krishnan to the role of executive vice president for cloud, where he will lead most of the company’s cloud-related efforts globally including business-development, marketing, engineering and customer delivery activities.
Krishnan most recently served as UK General Manager for Microsoft’s Developer Platform division where he was responsible in part for scaling the Azure business, which by most measures seems to be growing at record pace. Before joining Microsoft in 2004 he spent about five years at Trilogy, a Texas-based software firm specialising in lead generation solutions for the automotive, insurance and telecoms sectors.
“Great businesses make an extraordinary difference to the customers they serve. Canonical has the products and the momentum to do exactly that,” Krishnan said.
“I couldn’t be more excited to be joining the team at this time and helping shape the next phase of our journey”
Canonical has in recent months moved to bolster its cloud strategy with BootSack, its managed private cloud offering, and its own distribution of OpenStack. Its Linux distro Ubuntu is the most popular OS in use on AWS EC2 (though other Linux incumbents have questioned those claims), and it also recently launched Ubuntu Core, a slimmed-down, re-architected version of the Ubuntu operating system that borrows from heavily from the Linux container (isolated frameworks) and mobile (transactional updates) worlds.
