8:45 Monday morning. I fill the espresso filter basket with a good measure of Italian coffee, flick the switch to espresso, and 60 seconds later am rewarded with a demitasse of viscous caffeine, complete with the requisite creamy head. Coffee is an essential part of the I.T. toolkit, especially when deadlines loom and the disconnect between customer, 3rd party supplier and the gap between expectations and reality becomes wider by the day…
Installing and Configuring Linux Jails in PC-BSD
Whether you prefer the CLI or a GUI, one thing most people can agree on, is that The Warden is a great tool for managing jails. The Warden has been available as an add-on in PC-BSD since version 8, and is available as a port in FreeBSD as well. It now comes built-in to version 9.1 of PC-BSD and TrueOS (a variant of PC-BSD included in the install DVD that consists of FreeBSD and enhanced command line versions of PC-BSD tools). This article explains how to use the Warden to create a Linux jail, configure nat for it and instal Linux packages in the jail.
FreeBSD Enterprise Search with Apache Solr (Part 4)
So far, we have used Solr to access and index content found in web pages, XML files, databases and external websites. But as far as using Solr in the enterprise is concerned, how can we access disparate documents such as PDF and Microsoft Word files? This is where Apache Tika is invaluable – supporting over 14 different types of document formats. In the final part of our series on Apache Solr the author will look at Apache Tika and demonstrate how to import and index document content with Apache Solr.
This article provides an introduction to schemas, a feature of PostgreSQL that allow Database Administrators (DBAs) to organize their database objects, mainly tables, into name spaces in order to either avoid naming conflicts and better structure the database itself. All the examples shown here have been tested on a PostgreSQL 9.1 cluster running on a FreeBSD 8.2-RELEASE machine; all the example source code is available in a GitHub repository.
A simple DNS-DHCP Server for Small Business Network with dnsmasq
From this article you will learn how to setup and manage a Small Business DNS/DHCP server. A real example of small LAN business network are the so called “SoHo” (single office/home office SOHO), namely a category of businesses that has 1 to 10 employees, but this is only the staring point. In fact, there are examples of deployable environment for Dnsmasq configurations used for more than 1000 hosts. On the other side of the coin there are still some limitations, such as a very basic support for IPv6 router advertisements for DHCPv6 to work and the inability to serve many zone files (many domains), but this project brought us many surprises in time and will only get better. Knowing the strengths and limits of this daemon, a network administrator can now decide whether to install Dnsmasq.
Hardening FreeBSD with TrustedBSD and Mandatory Access Controls (Part 4)
Most system administrators understand the need to lock down permissions for files and applications. In addition to these configuration options on FreeBSD, there are features provided by TrustedBSD that add additional layers of specific security controls to fine tune the operating system for multilevel security. Since version 5.0 of FreeBSD, the TrustedBSD extensions have been included with the default install of the operating system. By default, this functionality is disabled and requires support to be compiled in or kernel modules to be loaded at boot time. For the purpose of this article, support will be loaded in with kernel modules already available with FreeBSD 9. Part 4 of the TrustedBSD series will cover the basic configuration of the mac_seeotheruids module.
EuroBSDcon and MeetBSD California: Two Continents, One Community
This year’s EuroBSDcon and MeetBSD California took place just a few weeks apart in two very different locations but together demonstrated seamless solidarity on the part of the BSD community. MeetBSD in Sunnyvale, California was like a reunion for many speakers and attendees who had recently met in Warsaw, Poland for EuroBSDcon. Some familiar European faces such as Robert Watson and Alexander Motin even made appearances only at the more distant event, showing once again that the geography of BSD and its community is "the Internet”. Read the overview describing both these wonderful events. Check what you have missed or refresh your memory.
The sixth edition of the Italian PostgreSQL Day (PgDay) held at the Monash University Center in Prato, Tuscany, on November the 23th has been a success. The Italian community did respond very well to the event, and guests from all over the country came to discuss, acquire knowledge and share experience about this great database. Here is a great example of how passion can gather people together. Just follow their steps.
