How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu
This document describes how to add WiKID two-factor authentication to Apache 2.x using mod_auth_radius on Ubuntu 12.04 Precise. It is recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.

Virtualization With KVM On A Scientific Linux 6.3 Server
This guide explains how you can install and use KVM for creating and running virtual machines on a Scientific Linux 6.3 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a Scientific Linux 6.3 server with PHP5 support (through PHP-FPM) and MySQL support.
Using mod_spdy With Apache2 On Scientific Linux 6.3
SPDY (pronounced "SPeeDY") is a new networking protocol whose goal is to speed up the web. It is Google's alternative to the HTTP protocol and a candidate for HTTP/2.0. SPDY augments HTTP with several speed-related features such as stream multiplexing and header compression. To use SPDY, you need a web server and a browser (like Google Chrome and upcoming versions of Firefox) that both support SPDY. mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This tutorial explains how to use mod_spdy with Apache2 on Scientific Linux 6.3.
Installing Apache2 With PHP5 And MySQL Support On Scientific Linux 6.3 (LAMP)

Setting Up An NFS Server And Client On Scientific Linux 6.3
This guide explains how to set up an NFS server and an NFS client on Scientific Linux 6.3. NFS stands for Network File System; through NFS, a client can access (read, write) a remote share on an NFS server as if it was on the local hard disk.
Scientific Linux 6.3 Samba Standalone Server With tdbsam Backend
This tutorial explains the installation of a Samba fileserver on Scientific Linux 6.3 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.
Detailed Error Handling In BashShell scripts are often running as background processes, doing useful things without running in a visible shell. To write such scripts can be quite painful, as all errors occur out of sight as well. While log files can hold a lot of information, finding the relevant information is a bit trickier. My solution is to log only the errors with all the details to a small database. This database contains tables for the message, the corresponding stack trace and the important environment variables. I have chosen for an SQLite database in this howto, but the same principle works with other databases as well.
