- Enabling Compiz On A Fedora 16 GNOME Classic Desktop (NVIDIA GeForce 8100)
This tutorial shows how you can enable Compiz on a Fedora 16 GNOME classic desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8100 here). With Compiz 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 16 - on my test system 3D support was working without any problems.
- Enabling Compiz On Linux Mint 12 (GNOME Classic)
This tutorial shows how you can enable Compiz on a Linux Mint 12 Lisa desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). With Compiz you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. Compiz is not supported on GNOME 3 yet, that's why this how-to is applicable only for the classic GNOME desktop.
- Enabling Compiz On Xubuntu 11.10 (Oneiric Ocelot)
This tutorial shows how you can enable Compiz on a Xubuntu 11.10 (Oneiric Ocelot) desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). Xubuntu uses the Xfce desktop environment which is a fast and stable alternative for those that are not happy with Unity or Gnome 3. With Compiz you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.
- Entering A Safe Mirror When Logging In With Unionfs And Chroot
When reading a hint on the website of LinuxFromScratch I discovered the special capabilities of unionfs, specially in combination with chroot. Later I read a HowTo on a wikiwebsite of Gentoo, about entering a chrooted home directory when using a special script as shell. Combining these two brings me to using a chrooted environment, which you enter when logging in as a special user. This environment is an exact copy (mirror) of the system you are working on. Because you are in safe copy of the real system, you can do whatever you like, it will never change the system, everything stays inside the cache (the readwrite branch).
- Fedora 13 Samba Standalone Server With tdbsam Backend
This tutorial explains the installation of a Samba fileserver on Fedora 13 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.
- Fedora 8 Server Setup - LAMP, Email, DNS, FTP, ISPConfig (a.k.a. The Perfect Server)
This is a detailed description about how to set up a Fedora 8 server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Fedora 8, but should apply to the 64-bit version with very little modifications as well.

This tutorial describes how to scan emails for image spam with FuzzyOCR on a Debian Lenny server. FuzzyOCR is a plugin for SpamAssassin which is aimed at unsolicited bulk mail containing images as the main content carrier. Using different methods, it analyzes the content and properties of images to distinguish between normal mails (ham) and spam mails. FuzzyOCR tries to keep the system load low by scanning only mails that have not already been categorized as spam by SpamAssassin, thus avoiding unnecessary work.
- Filtering PDF-/XLS-/Image-Spam With ClamAV (And ISPConfig) On Debian/Ubuntu
There is currently a lot of spam where the spam information is attached as .pdf or .xls files, sometime also hidden inside a .zip file. While these spam mails are not easy to catch with e.g. SpamAssassin or a Bayes filter, the ClamAV virus scanner can catch them easily when it is fed with the correct signatures as ClamAV is built to scan mail attachments.
- First Steps Of Running Linux Via Terminal Instead Of Desktop
This tutorial is supposed to show new Linux users how to handle Linux without having to browse through your desktop to edit files. The core commands to do this are the same on every Linux distribution, however there is a large variety of commands that differ from distribution to distribution, as does the install command.
- Flexnet License Monitoring With rrdtool
Some of you may know the commercial Flexnet Licencing Application. It's a client-server based solution for managing the usage of socalled Flexnet-enabled applications. You can hold licenses of more than one product on one license-server. As you typically have to buy licenses and licenses can be expensive it would be nice to have a monitoring solution to see the utilization of the precious licenses, whether they are underutilized or are always fully utilized which is also a waste of resources. As far as I know there are commercial applications for performing such reports, but again you have to spend money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"?
- Full Mail Server Solution w/ Virtual Domains & Users (Debian Etch, Postfix, Mysql, Dovecot, DSpam, ClamAV, Postgrey, RBL)
This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch). I was asked to design a secure, scalable, portable solution for a small company. While the guide references many servers, the company only had 4 physical machines, Xen was used to virtualize the entire solution. That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision.
- Generating Web Site Statistics With AWStats & JAWStats On Debian Lenny
This tutorial explains how you can generate statistics for your web site with AWStats and JAWStats on a Debian Lenny web server. AWStats is a free powerful and featureful tool that generates advanced web server statistics. JAWStats runs in conjunction with AWStats and produces clear and informative charts, graphs and tables about your website visitors. AWStats is able to create graphical web pages for the statistics, but JAWStats presents this data in a much nicer way - it's much better organized and makes use of Ajax and Flash.
- Groupware Server With Group-Office, Postfix, Dovecot And SpamAssassin On Debian Lenny (5.0)
In this howto I will explain how you can set up a groupware server using the Debian Linux operating system, Group-Office for managing the mailboxes and groupware functions like e-mail, shared calendars, file sharing etc., Postfix with virtual accounts in MySQL, Dovecot IMAP, SpamAssassin spam filter, and a vacation perl script that will handle out-of-office replies.
- High-Availability Replicated Storage With GlusterFS 3.2.x On Ubuntu 11.10
This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 11.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 11.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

- Host Based Intrusion Detection - Samhain
This article describes in some detail how to install Samhain, the host based intrusion detection system. I am not going to ramble on about what host based intrusion detection is or why to use it, as there are plenty of articles already covering those subjects. This article is just to show you how to get Samhain up and running in a client / server configuration with a couple bells and whistles thrown in for fun.
