Horde webmail error

Written by AlanV on April 9, 2009 – 10:49 pm -

If horde webmail is not working on windows + plesk server and receiving following errors when login to horde….

Warning: main() [function.include]: Failed opening ‘PEAR.php’ for inclusion (include_path=’C:\Inetpub\vhosts\webmail\horde\lib;.;./includes;./pear’) in C:\Inetpub\vhosts\webmail\horde\lib\core.php on line 46

Warning: main(): Failed opening ‘PEAR.php’ for inclusion (include_path=’C:\Inetpub\vhosts\webmail\horde\lib;.;./includes;./pear’) in C:\Inetpub\vhosts\webmail\horde\lib\core.php on line 26

And so on………

This happens mainly because PHP and Zend installers force PHP to use a default configuration file for all applications, but horde uses a special configuration file which is placed to its folder.

Please edit registry by command regedit and clean up the default configuration location by removing the following key:

Linux Desktop Environments

Written by Mike on September 27, 2008 – 3:00 am -

You’ve heard about “Gnome” and “KDE” and more—these Linux-related things are “Desktop Environments.” If you’re making the switch, which one is for you?

If you’re a Windows user who hasn’t experimented with the myriad of free Linux distros available, this one’s for you. Let’s take a look at some of the most popular Linux Desktop Environments that sit on top of the Operating System (OS). A Desktop Environment (DE) typically provides a GUI: windows, icons, folders, toolbars, and abilities like dragging and dropping of files from one folder to another. Any DE will therefore include a window manager, file manager, taskbar, and more.



The GNU Network Object Model Environment, or GNOME, is an international open source effort to build the simplest and most intuitive GUI for a DE. It’s one of the few DEs that have consistently matched their production timelines, releasing a new version every six months. Currently, it stands at version 2.24. This version focuses on document security, and incorporates privacy features that enable you to digitally sign or authenticate files using Seahorse, an application created for the purpose. That apart, this version also focuses on managing laptop batteries efficiently, and increases the stability and responsiveness of the OS. GNOME’s popularity in the open source world is due to its exhaustive set of developer guidelines— known as Human Interface Guidelines—to be followed when creating an application for the environment. The guidelines ensure applications don’t look too different from each other, and that some basic options like closing, minimizing, and re-sizing, among others, are placed in the same location across all applications. GNOME’s design keeps novices in mind. The DE does not have a lot customization options, and contains menus with an exhaustive set of explanation notes. The main reason most Windows converts should stick to this DE is because it provides a well-documented FAQ section, and a very active online community that will answer any newbie’s questions.



The K Desktop Environment, or KDE, is another DE that runs on UNIX and Linux distros. KDE believes in the manifesto that all components used to build the DE, and the applications that come bundled with it, have to be free and open source in the truest sense of the word, with no restrictions whatsoever on the user. The major difference from GNOME lies in the fact that KDE is not entirely geared towards the novice. It allows for complete customization, which might intimidate; having said that, there are a good set of applications that allow you to start using a KDE-based distro as soon as you install it. Applications like KOffice, Amarok, and Konqueror are some of the more popular KDE applications. KDE allows you to mimic OSes such as Mac OS X, so if you’re the type who likes to have complete control over each and every aspect of his OS, this is the platform you might want to use. The most popular distributions on this platform include Fedora (formerly Fedora Core)—though it’s not the default environment—and Knoppix.


XFCE Unlike GNOME or KDE, Xfce is a lightweight DE designed to work with computers that have both older and newer hardware. It is very user-friendly, and incorporates a minimal set of customizable options. The file system hides system and configuration files from view so they can’t be tampered with by the novice. In comparison to GNOME or KDE, Xfce is regarded the most responsive DE. It uses its own file manager, called Thunar. One advantage of using Xfce is its install size, all of 50 MB to be exact. Popular distros that use Xfce as their default DE include Xubuntu, SLAX, and dyne:bolic.

There are other DEs not as popular as the three above, but worth a mention:


A proof-of-concept DE based on the “Laws of Interface Design.” It aims at presenting all information collectively, in one place, thereby completely debunking popular concepts such as the Desktop being a folder, and the menu system having nested folders. Instead, it presents all the needed information on the Desktop, and holds tasks and files related to “System”, “Files”, “Programs”, and “Trash” in four windows on the screen. Mezzo is available as a .deb package, which is like an .exe file in Windows, for installation on all

Debian-based distros like Ubuntu, Freespire, and Knoppix.

Project Looking Glass

A DE written entirely in Java, Project Looking Glass aims at creating 3D Desktop Environment that can run on computers with low-end hardware. One of the most notable features is the creation of “reversible windows”: you can write notes or leave comments on the back of any window! Windows can be tilted or rotated to the angle of your choice, and can also be made semi-transparent.

Free email virus scanner

Written by Swapnil on September 22, 2008 – 6:04 pm -

I have made nice doc for those want to use free email virus checker instead of Dr. Web. (why should i pay more ;)

First check in the System/Services if Dr.Web AV is stopped. Dr.Web AV needs license above the 15th email. There is tested and free alternative.

ClamAV – is available in windows in 2 variants – ClamWIN which is more user friendly and more aimed to scanning computers – and exact replica of Linux ClamAV which is the only working variant supported by Plesk:


Go to the page, download the latest version and install it. Run freshclamav once in a while or even better setup a scheduler to do it once daily.

Then go to System/Services and find the clamav service. Click on properties and set it up to run automatically.

Restart the VPS.

Go to Plesk and login as administrator.

Click on System-Server

Click Defaults Components (should it be Default components I would say?)

ClamAV should be one of the available antivirus options. Select it, and (maybe) restart VPS once again.

That would be it. If you want to know how to use antivirus from plesk then consult their manuals.

Configure Virtual Private Network on Windows Virtual Private Server.

Written by Pritam on September 22, 2008 – 6:02 am -

Following steps to configure the Virtual Private Network on Windows Virtual Private Server.

1. For windows Virtual Private Server, First you need to enable “NAT” for your Virtual Private Server. This must be done from the Main Hardware Node. We will do it on our Main Hardware Node.

2. After enabling “NAT” for your Virtual Private Server, Go to Start >> RUN >> Type “services.msc” in you Virtual Private Server
On the services list, select “Routing and Remote Access” and go to properties. Make the startup type automatic and apply. After that you should have the option to “Start” this service. Start this service as we are going to use this service basically to route our traffic

3. Now go to Start >> Settings >> Control Panel >> Administrative Tools >> Click on the shortcut says “Routing and Remote Access”. It should open the configuration panel of Routing and Remote Access.

4. Now right click on your computer name the click the option says “Configure and Enable remote and routing access”. Before doing this, make sure your Firewall service is stopped and disabled.

5. Now on the configuration wizard click Next to proceed >> In the configuration list select “Custom Configuration”, Press Next >> Select Virtual Private Network Access & NAT and Basic Firewall Option, Press Next >> Now press Finish to end the wizard.

This wizard should enable the PPTP & L2TP Virtual Private Network access to your firewall with private routing capability. Now you need to configure your Virtual Private Server to route the private Traffic to the Public Interface. To do this, we need to have any of the following two:

1. Two network interface to route one to another. or
2. We can use NAT (Network Address Translation) using the Microsoft Loopback adapter.

We will basically work with the 2nd one as Virtual Private Server don’t come with two network interfaces. To continue with the NAT configuration, go to the Routing and Remote Access panel >> Expand ComputerName (Local) >> Expand Ip Routing >> You should find a option says “NAT/Basic Firewall”. Simply right click on that option and use the New interface to add network translation. Now first add the Inferface says “Internal” which is basically for private network access with default settings and on second attempt add your main adapter to the NAT list and select the options says “Public Interface connected to this inferface” and select the option says “Enable NAT on this interface”.

Now your network should have the address translation working, that means your private requests should be now translated and you can use this Virtual Private Network as your internet gateway.

Now to allow your users to use Virtual Private Network, add a new user and from the properties allow its Dial In permission. User with Dial-In permission should be able to login using Virtual Private Network.

Windows PowerShell

Written by Mike on September 11, 2008 – 2:09 am -

Windows PowerShell (or PS) is an extensible command-line shell and associated scripting language that helps IT professionals achieve greater control and productivity. It was released in 2006 and is currently available for Windows XP SP2, Windows Server 2003, Windows Vista and is included in Windows Server 2008 as an optional feature.

Windows PowerShell integrates with the Microsoft .NET Framework and provides an environment to perform administrative tasks by execution of cmdlets OR commandlets which are specialized .NET classes implementing a particular operation, scripts which are composition of cmdlets or executables which are standalone applications. All These task like accessing data in different data stores, like filesystem or registry, which are made available to the PowerShell runtime via Windows PowerShell providers.

Windows PowerShell also provides a hosting mechanism through which the Windows PS runtime can be used inside other applications, which can then inhance Windows PS functionality to implement certain operations, including those exposed via the graphical interface. This capability has been utilized by Microsoft Exchange Server 2007 and other Microsoft applications like “Microsoft SQL Server 2008″ to increase its management functionality through PowerShell cmdlets. In the future, graphical interface-based management applications on Windows will be layered on top of Windows PowerShell.i

Windows PowerShell includes its own extensive, console-based help, same as of man pages in Unix shells. The help topics include help for cmdlets, providers, and concepts in PowerShell. To see the help, use the Get-Help cmdlet.
