Gathering log messages is important. In a lot of situations you'll want to store all entries of logfiles on another server. If a server crashes or gets hacked you want to be able to browse through logfiles from this machine and you want to be sure these log files are not altered in any way. This can be accomplished using a central logserver that receives messages from all other hosts. This howto describes rsyslog putting log messages in one file per day per remote host. Rsyslog is the current standard in RHEL6 and available as a package in the current package streams in RHEL 5.5 (and CentOS 5.5). Setting up rsyslog is pretty simple. It all comes down to a single config file but (there is always a but) every setting needs some planning.

This guide explains how you can run virtual machines with VirtualBox 4.0 on a headless Fedora 14 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Here is the guide on installing Firebird 2.5 from FreeBSD 8.1 Ports and creating your first test database; also we show you how to install Flamerobin GUI (administration tool) and the PHP driver for it. This was tested on fresh FreeBSD 8.1 on a virtual machine.

Cherokee is a very fast, flexible and easy to configure Web Server. It supports the widespread technologies nowadays: FastCGI, SCGI, PHP, CGI, TLS and SSL encrypted connections, virtual hosts, authentication, on the fly encoding, load balancing, Apache compatible log files, and much more. This tutorial shows how you can install Cherokee on a Fedora 14 server with PHP5 support (through FastCGI) and MySQL support.

This guide explains how you can install and use KVM for creating and running virtual machines on an OpenSUSE 11.3 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.

It seems like operations that communicate with userspace are really discouraged. And I am not arguing with that. Although it doesn't mean that they cannot be accomplished. A driver loads configuration that could be stored only on HDD. When MS Windows XP boots up it remembers that I have turned Bluetooth off so it is not powered on, unlike even the latest Linux (Fedora 14 at the moment of writing) – such functionality in many drivers was not implemented. When developer uses procfs or character devices there should be another software or script in boot sequence that is actually sending information from a file to particular device. After some time looking over the internet I have managed to write such module that reads a file.

Firewall Builder is a firewall configuration and management GUI that supports configuring a wide range of firewalls from a single application. Supported firewalls include Linux iptables, BSD pf, Cisco ASA/PIX, Cisco router access lists and many more. In this tutorial we are going to cover how to use Firewall Builder to configure a NAT rule that translates both the source and destination IP addresses of the original packet. This type of NAT configuration can be useful in a variety of network configurations.

Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

This tutorial provides step-by-step instructions on how to install VMware Server 2 on a Fedora 14 desktop system (with kernel 2.6.35). With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, FreeBSD, etc. under a host operating system. This has the benefit that you can run multiple operating systems on the same hardware which saves a lot of money, and you can move virtual machines from one VMware Server to the next one (or to a system that has the VMware Player which is also free).

This describes how to set up ssl certificates to enable encrypted connections from PgAdmin on some client machine to postgresql on a server machine. The assumption is that postgresql (compiled with ssl support) and openssl are already installed and functional on the server (Linux). PgAdmin is already installed on the client (either Windows or Linux).

In this HowTo I will describe how to prepare a Fedora 14 server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

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 Fedora 14 server with PHP5 support (through PHP-FPM) and MySQL support.

You might know this situation: you want to generate a GPG or SSL key, and during that operation, your system tells you that no more random bytes are available and that it needs to collect more entropy, and you are stuck. This short guide tells you how to solve this problem with the package rng-tools on Debian Lenny.

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Fedora 14 server with PHP5 support (through FastCGI) and MySQL support.

Atmail Open is an open source webmail client which is available free of charge and is a great alternative to Squirrelmail. This tutorial shows how to use it (instead of SquirrelMail) with ISPConfig 3.

This tutorial shows how you can enable Compiz Fusion on a Fedora 14 GNOME desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8100 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. I will use the free nouveau driver in this tutorial instead of the proprietary NVIDIA driver. nouveau is an accelerated Open Source driver for NVIDIA cards that comes with experimental 3D support on Fedora 14 - on my test system 3D support was working without any problems.

This tutorial shows how you can install your honeypot by using Honeyd (Virtual Honeypot). Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their personality can be adapted so that they appear to be running certain operating systems.
