Creating Your Own Custom Ubuntu 7.10 Or Linux Mint 4.0 Live-CD With Remastersys

This guide shows how you can create a Live-CD from your Ubuntu Gutsy Gibbon or Linux Mint 4.0 system with a tool called remastersys. Remastersys is available in the Linux Mint romeo repository. You can customize your Ubuntu/Linux Mint system and then let remastersys create an iso image of it which you can then burn onto a CD/DVD. http://www.howtoforge.com/ubuntu-linux-mint-livecd-with-remastersys

Using KVM On Ubuntu 7.10 (Gutsy Gibbon)

In this HowTo I will explain how to install and use KVM for running your services in virtual machines. KVM (Kernel-based Virtual Machine) is a Linux kernel virtualization technique that provides full virtualization by using Intel VT (Vanderpool) or AMD-V (Pacifica). http://www.howtoforge.com/using-kvm-on-ubuntu-gutsy-gibbon

How To Set Up Software RAID1 On A Running System (Incl. GRUB Configuration) (Debian Etch)

This guide explains how to set up software RAID1 on an already running Debian Etch system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one). http://www.howtoforge.com/software-raid1-grub-boot-debian-etch

Enabling Compiz Fusion On An Ubuntu 7.10 Desktop (NVIDIA GeForce FX 5200)

This tutorial shows how you can enable Compiz Fusion on an Ubuntu 7.10 (Gutsy Gibbon) desktop (I am using an NVIDIA GeForce FX 5200 graphics card). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. http://www.howtoforge.com/compiz-fusion-ubuntu-gutsy-gibbon-nvidia-geforce-fx-5200

Adding And Updating SpamAssassin Rulesets With RulesDuJour

This article explains how you can download additional SpamAssassin rulesets resp. automatically update these rulesets with a shell script called RulesDuJour. These additional rulesets can increase your spam recognition rate dramatically. Most of the rulesets that RulesDuJour supports can be found on the SA Rules Emporium web site. http://www.howtoforge.com/adding-and-updating-spamassassin-rulesets-with-rulesdujour

Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 7.10)

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

SAMBA (Domaincontroller) Server For Small Workgroups With Ubuntu 7.10

This is a detailed description about setting up an Ubuntu based server (Ubuntu 7.10) to act as file- and printserver for Windows(tm) workstations in small workgroups. This howto uses the tdb backend for SAMBA to store passwords and account information. This is suitable for workgroups for up to 250 users and is easier to set up than an LDAP backend. http://www.howtoforge.com/ubuntu-gutsy-samba-domaincontroller

Installation Guide: Linux Mint 4.0 Daryna (a.k.a. The Perfect Desktop)

This tutorial shows how you can set up a Linux Mint 4.0 (Daryna) desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. Linux Mint 4.0 is a Linux distribution based on Ubuntu 7.10 that has lots of packages in its repositories (like multimedia codecs, Adobe Flash, Adobe Reader, Skype, Google Earth, etc.) that are relatively hard to install on other distributions; it therefore provides a user-friendly desktop experience even for Linux newbies. http://www.howtoforge.com/desktop-installation-guide-linux-mint-4.0-da

Intrusion Detection: Snort, Base, MySQL, and Apache2 On Ubuntu 7.10 (Gutsy Gibbon)

In this tutorial I will describe how to install and configure Snort (an intrusion detection system (IDS)) from source, BASE (Basic Analysis and Security Engine), MySQL, and Apache2 on Ubuntu 7.10 (Gutsy Gibbon). Snort will assist you in monitoring your network and alert you about possible threats. Snort will output its log files to a MySQL database which BASE will use to display a graphical interface in a web browser. http://www.howtoforge.com/intrusion-detection-with-snort-mysql-apache2-on-ubuntu-7.10

How To Enable Multiple HTTPS Sites For One IP On Debian Etch Using TLS Extensions

This guide is Debian specific but could be ported to other distributions since the concept is the same. In order to use TLS Extensions we have to patch and recompile Apache2 and recompile OpenSSL with the enable-tlsext directive. Since TLS extensions are relatively new, some Internet browsers will not work so the Apache2 server will deliver just the default site as http 1.0 does on an http 1.1 server. http://www.howtoforge.com/enable-multiple-https-sites-on-one-ip-using-tls-extensions-on-debian-etch

Enabling Compiz Fusion On An Ubuntu 7.10 Desktop (ATI Mobility Radeon 9200)

This tutorial shows how you can enable Compiz Fusion on an Ubuntu 7.10 (Gutsy Gibbon) desktop (the system must have a 3D-capable graphics card - I am using an ATI Mobility Radeon 9200 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. http://www.howtoforge.com/compiz-fusion-ubuntu-gutsy-gibbon-ati-mobility-radeon-9200

How To Manage An iPod From A Linux Desktop With Songbird 0.3

This article shows how you can use an iPod on a Linux desktop with Songbird 0.3. It covers how you can upload MP3 files from your desktop to your iPod, download MP3 files from your iPod to your desktop, and how you can delete files on the iPod. Normally, Apple's iTunes software is needed to manage an iPod, but iTunes is not available for Linux. Fortunately, there are Linux alternatives such as Songbird that can handle the task. http://www.howtoforge.com/using-an-ipod-with-songbird-0.3

How To Make Desktop Applications Start Automatically After Login (GNOME)

You probably know this: you power on your machine, and immediately after you have logged in you manually start your two or three favourite applications. Why not have the system start these applications for you automatically? This short guide shows how to accomplish this under GNOME. http://www.howtoforge.com/make-desktop-applications-start-automatically-gnome

The Perfect Desktop - gOS 1.0.1

This tutorial shows how you can set up a gOS 1.0.1 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. gOS is a lightweight Linux distribution, based on Ubuntu 7.10, that comes with Google Apps and some other Web 2.0 applications; it uses the Enlightenment 17 window manager instead of GNOME or KDE. http://www.howtoforge.com/the-perfect-desktop-gOS-1.0.1

Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Debian Etch

This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Debian Etch. The load balancer sits between the user and two (or more) backend Apache web servers that hold the same content. Not only does the load balancer distribute the requests to the two backend Apache servers, it also checks the health of the backend servers. If one of them is down, all requests will automatically be redirected to the remaining backend server. In addition to that, the two load balancer nodes monitor each other using heartbeat, and if the master fails, the slave becomes the master, which means the users will not notice any disruption of the service. HAProxy is session-aware, which means you can use it with any web application that makes use of sessions (such as forums, shopping carts, etc.).
