Soon, someone will listen and they will take advantage of your lack of security awareness. SSH is an industry standard that replaces Telnet and other remote console management applications. SSH commands are encrypted and are kept confidential in several ways. When using SSH, a digital certificate will authenticate the connection between the client (your workstation) and the server (your network device) and encrypt the protected password ...

How to install Nutch and Hadoop to search for Web pages and mailing lists, there seem to be few articles on how to install Nutch using Hadoop (formerly DNFs) Distributed File Systems (HDFS) and MapReduce. The purpose of this tutorial is to explain how to run Nutch on a multi-node Hadoop file system, including the ability to index (crawl) and search for multiple machines, step-by-step. This document does not involve Nutch or Hadoop architecture. It just tells how to get the system ...

A few weeks ago, I published a blog about Windows Azure cloud services. I'm digging up new things and experimenting with mac,pc and Linux (I prefer Ubuntu). As a fan of PowerShell and command lines for a long time, I've been looking for ways to handle transactions in text mode, as well as the creation and deployment of script sites. There was a whole bunch of ways to access Azure using the command line-more than I thought. There is a JSON based Web API that will let those workers ...

Foreword in the first article of this series: using Hadoop for distributed parallel programming, part 1th: Basic concepts and installation deployment, introduced the MapReduce computing model, Distributed File System HDFS, distributed parallel Computing and other basic principles, and detailed how to install Hadoop, How to run a parallel program based on Hadoop in a stand-alone and pseudo distributed environment (with multiple process simulations on a single machine). In the second article of this series: using Hadoop for distributed parallel programming, ...

What we want to does in this short tutorial, I'll describe the required tournaments for setting up a single-node Hadoop using the Hadoop distributed File System (HDFS) on Ubuntu Linux. Are lo ...
