The Horde Project provides a PHP-based Application Framework. It consists of webmail program IMP, a contact manager Turba, the calendar manager Kronolith, and many others. It also uses a backend-independent interfaces for dealing with preferences, logfiles, MIME, hierarchical data, authentication, data formats, encryption, forms, session handling, file storage and remote procedure calls.

NoMachine NX is a Terminal Server and remote access solution based on a comprising set of enterprise class open source technologies. NX makes it possible to run any graphical application on any operating system across any network connection at incredible speed. FreeNX application/thin-client server is based on NoMachine’s NX technology. It can operate remote X11 sessions over 56k modem dialup links or anything better. FreeNX package contains a free (GPL) implementation of the nxserver component. The following workshop describes the FreeNX installation on a Mandriva 2008 Free server. Additionally it explains how to access it using a Windows XP and an OpenSuse 10.3 client.

KDE 4 is the next major release of the K Desktop Environment software. It contains a new multimedia API, called Phonon, a device integration framework called Solid and a new style guide and default icon set called Oxygen. Let me say this first: KDE 4 is still not ready but it is nice to see the major improvements in usability, performance and stability. KDE 4 (preview) is already included in the latest Mandriva release. This article describes the installation on a Mandriva 2008 desktop

SSL is especially suited for HTTP since it can provide some protection even if only one side of the communication is authenticated. In the case of HTTP transactions over the Internet, typically, only the server side is authenticated. This workshop explains how to setup a virtual host using OpenSSL and TinyCA on an OpenSuse 10.2 server.

Virtual hosts are used to run more than one web site on a single machine. Virtual hosts can be "IP-based", meaning that you have a different IP address for every web site, or "name-based", meaning that you have multiple names running on each IP address. You can also run your web pages on different ports like 8080 or 8090. The fact that they are running on the same physical server is not apparent to the end user. This workshop describes the different setups based on an OpenSuse 10.2 server.

How to make a server room full with Linux security appliances available to traveling users?  If you are traveling a lot with your laptop and if you like to have the same level of security as within your  company’s corporate network – this is perhaps a solution for you.
Yoggie has developed a small device with a powerful 520 Mhz Intel Processor that fits in your pocket. It looks like a USB Memory Stick but it runs a complete hardened Linux-based Operating System inside. The solution combines a statefull inspection firewall and NAT combined with other security applications like Proxies, Anti-Virus, Spyware- and SPAM Protection.

Xara Xtreme for Linux is a powerful, general purpose graphics program for Unix platforms including Linux, FreeBSD and (in development) OS-X. Xara Xtreme is based on Xara Xtreme for Windows . The source code was made available open-source in early 2006, and is being ported to Linux. The downloadable  version of Xara Xtreme for Linux  is working straight away on most Linux machines, but  the development is continuing daily. At the moment  two versions are available for download. The first is the recommended download because it will normally be the most stable. The second is the very latest, but untested version, built and published automatically. Warning: It may be unstable. Linux-Tip was using  the latest stable version provided as an “Autopackage Archive” on a Open Suse 10.2 Desktop. We recommend connecting your system to the Internet. In this case the script  can easily download and install the necessary packages automatically.

The VectorLinux Website is promising: “Speed, performance, stability -- these are attributes that set VectorLinux apart in the crowded field of Linux distributions. VectorLinux is a lighterweight, fast, Linux operating system for Intel-AMD x86 compatible systems and is based upon Slackware, one of the original Linux distributions…” Linux-Tip was testing the installation and usage of version 5.8 (Standard Gold).

One way to enforce the traffic security is to use the SSH by the way of X11 tunneling or port forwarding. SSH was developed  to replace the insecure telnet, ftp,  rcp, rlogin, rsh software. FreeNX is already perfectly using this technology. In this article I will show, how to forward X11 using ssh without any additional software on the Linux site. Additionally I will explain how to run Linux applications on Windows XP clients using PuTTY and X-Deep/32.

NoMachine NX is a Terminal Server and Remote Access solution based on open source technologies. It makes it possible to run any graphical application on any operating system across any network connection as if you were sitting in front of your computer.

Commercial filters are often expensive, especially when used on a large number of computers, as would be the case in a school computer lab or in small or medium companies with computer networks. In contrast, open source filters are generally freely available for download. In addition, since commercial filters are proprietary, in many cases the system administrator does not have the opportunity to modify or even view the lists of blocked sites. 

All Internet content carries a risk. Content Filtering helps companies and home users to stop unwanted data. It is used as part of Internet Firewalls or Proxy Servers to screen the content of all incoming Internet traffic. Content filtering usually works by specifying character strings that, if matched, indicate undesirable content that is to be screened out. Content is typically screened for pornographic content and sometimes also for violence- or hate-oriented content.

Well, I got my laptop on Friday two weeks ago. I must say, the HP Compaq nx6310 was definitely a good choice. The only thing I don’t really like is the TrueLife screen. I don’t like it because of the glare, but I suppose I’ll get used to it. Anyway, one of the first things I did was partition the drive, and install OpenSuse 10.2, 64bit version. The installation went smoothly and everything (including WLAN) worked perfect. In this workshop I want to explain the installation of the 3D cube using XGL and Compiz.

Patch management has become an area of concern for business networks and home networks as well. Updates and patches are continually developed by vendors to improve their solutions. Most network administrators would know the chaos resulting from the release of a new critical patch. PatchQuest is patch management software that frees administrators from manually managing patches for their existing Windows/Linux installations. Linux-Tip tested the free edition , which can manage up to 5 computers.

Metisse is a window manager developped by the In Situ project. It is available under the GPL Licence. Mandriva Linux is using Metrisse in its latatest Live-CD. Metisse differs from a classic 3D desktop ("the cube") in the way that it offers innovative windows interactions, thus enforcing work efficiency.

Looking Glass is an open source development project based on and evolved from Sun Microsystems' Advanced Development division. It supports running unmodified existing applications in a 3D space, as well as APIs for 3D window manager and application development. At the moment, existing application integration is supported for Linux and Solaris x86 platforms. The platform for 3D application development is available for Linux, Solaris and Windows platforms. Linux-Tip.net was testing the LG3D Mega-bundle which integrates all the software necessary to run lg3d. This includes the jdk, java3d and lg3d itself.

This workshop describes how to install VMware server 1.0.1 on Mandriva 2007 64-bit systems. Additionally you will get information how to install Linux and Windows clients to access the VMWare Server. With VMware Server you can create and run guest operating systems ("virtual machines") such as Linux, Windows, BSD, etc. under a host operating system.

Windows Vista provides two entirely new features to manage windows using Windows Flip and Windows Flip 3D. Linux is already using this technology. 3D-Desktop is an OpenGL program for switching virtual desktops in a seamless 3-dimensional manner on Linux. The current desktop is mapped into a full screen 3D environment where you may choose other screens.
