Offline Update Nod32 Antivirus

linglom — Wed, 16 Sep 2009 02:05:17 +0000

Introduction

If you have a stand alone PC which doesn’t has an Internet connection and you have installed nod32 antivirus, nod32 antivirus will not be able to download update for the signature so you have to update the virus signature database manually. Otherwise, your PC may be at risk of virus attacks.

On this example, I show how to update virus signature database of nod32 antivirus version 4 business edition. You also can apply these steps to nod32 antivirus version 2, 3 and home edition. But I have not include the update for version 2 so you have to find the update file somewhere else.

Step-by-step

You see the virus signature database is failed to update on a stand alone PC.
Download virus signature database of nod32 anti-virus from Virus Signature Update for Nod32 v3 & v4
Extract the downloaded file to a folder. On this example, I extract to c:\.
Open Eset Nod32 Antivirus, click on Setup -> Toggle Advanced Mode.
On Toggle Advanced Mode, click Yes.
Open Advanced Setup window. Click on Setup -> Advanced Setup.
Edit Update Server. On Setup, click on Update on the left menu -> Edit.
On Update Server list, copy the path from the extracted folder on step 2 to Update Servers box and click Add. On this example, I copy “C:\update nod32v3v4_4360″ and paste to Update Servers box. Then, click OK.
You notice that the value on Update Server box is changed. Click OK.
Click Update -> Update virus signature database.
Now the virus signature database is updated.

Working with ISO Image and MDF/MDS using Daemon Tools Lite, Part 5: Mount Disk Image

linglom — Sat, 01 Aug 2009 16:17:28 +0000

Mount Disk Image

From the 2 previous posts – part 3: Create an ISO Image and part 4: Create MDF/MDS files, you have create disk image files. Now it is time to use them. In this post, I will show you how to mount an MDS file which is an image file that was created on part 4 to a virtual drive.

You can see the index of this series at Working with ISO Image and MDF/MDS using Daemon Tools Lite, Part 1: Introduction

Step-by-step

I copy the disk image files to another computer which also has Daemon Tools Lite installed. It has drive E: as a virtual drive.
Note: A virtual drive is added automatically when you installed Daemon Tools.
You can minimize the Daemon Tools Panel by click on down-ward triangle icon on the rightmost of the tray.
Let’s begin to mount an image file to a virtual drive. Right-click on Daemon Tools Lite icon and highlight on Virtual CD/DVD-ROM. You will see Drive 0: [ E: ] No Media. This is a virtual drive that we can mount an image file to.
Note: You can highlight on Set number of devices and select a number of virtual drives that you want on your computer. On Lite version, you can have up to 4 virtual drives.
Highlight on Drive 0: [ E: ] No Media and select Mount image.
Browse to an image file that you want to mount. In this example, it is Audio CD.mds. Click Open to continue.
Daemon Tools Lite supports mounting these disk image formats:
- Media descriptor files (.mds)
- BlindWrite images (*.b5t, *.b6t)
- Blindread images (*.bwt)
- CloneCD images (*.ccd)
- Cue sheets (*.cue)
- Compressed ISO images (*.isz)
- Nero images (*.nrg)
- Instance CD/DVD images (*.pdi)
- Disc Juggler images (*.cdi)
- Standard ISO images (*.iso)
Once you have mounted an image file to a virtual drive, you can access content of the image file. In this example, Windows has detected new disc has been inserted into a virtual drive and asks what do you want to do. So I select Play audio CD.
Windows Media Player plays the image file which has been mounted to a virtual drive as if it is an original disc.
Also, you can see that Drive E: is marked as Audio CD in My Computer.
You can unmount the image file by select a virtual drive and choose Unmount image.

Summary

This is the last part of the series of Working with ISO Image and MDF/MDS using Daemon Tools Lite. I hope you get better understanding about disk image files and how to work with them. If you have any suggestion or want to share your experience, feel free to post it below.

Working with ISO Image and MDF/MDS using Daemon Tools Lite, Part 1: Introduction

Introduction

ISO Image

ISO image or disk image is an archive file of a CD/DVD, or any other disc format. An ISO image contains files and folders which are on the disc. The concept is similar to a zip file except that the data that stored on an ISO image is stored in an uncompressed format. ISO images do not support multi-session, so they cannot be used for audio CDs, VCD, and hybrid audio CDs.

MDF/MDS

MDF/MDS (Media Descriptor Image file) both also are a disc image format. MDS is an optional media descriptor file. It contains meta-data about the original media while the MDF file is an archive file. MDF/MDS supports multi-session, hence it can be used for audio CDs, VCD, and hybrid audio CDs.

Why use Disk Image file?

The benefits of disk image are

A disk image can be burned to a CD or DVD by using any image burner software.
Easy to backup and maintain data because it is a file.
Better access rates than a optical drive when using a virtual disc.
No more noise from CD or DVD anymore when using a virtual disc.

With these benefits, it is a good to start to use a disk image file instead CD/DVD. In this series, I will show you how to create a disk image files both ISO image and MDF/MDS. Then, how to mount an image file as a virtual drive to access data without using the original CD/DVD anymore. The software that I use in this series is Daemon Tools Lite version. It is free license if you use at your home and not for commercial purpose. Otherwise, you have to buy it.
Note: There are many other disk image software such as Alcohol 120%, CloneDVD, ImgBurn, IsoBuster, MagicISO, Nero Burning ROM, PowerISO, UltraISO, etc. They are different in features and supported format. Some can only create an image file, some can only burn an image file, etc.

Daemon Tools

DAEMON Tools is an advanced application for Microsoft Windows which provides one of the best optical media emulation. With DAEMON Tools you can back up your physical CD/DVD/HD DVD/Blu-ray discs into “virtual discs” or so called “disc image” files, which run directly on your hard drive.

Here is the features of Daemon Tools Lite version:

Emulate virtual CD/DVD-ROM/HD DVD and Blu-ray drives. DAEMON Tools Lite enables you to emulate up to 4 CD/DVD virtual drives on your computer.
Create a disc image. With DAEMON Tools Lite, you can create ISO and MDS image files from original discs inserted in physical CD/DVD drive.

Note: Daemon Tools Lite is also supported on Windows 7 Beta version.

How to Create .htaccess file on Windows

linglom — Wed, 24 Jun 2009 03:04:26 +0000

Problem

The .htaccess is a file that use to rewrite URL on a web server. It is the file that doesn’t has a name, only an extension. The problem comes when you want to create the file on Windows operating system. You can’t create a file without a name. If you try to create the .htaccess file, you will receive a error message: “You must type a file name”. The example below shows the error message when I tried to rename a file htaccess.txt to .htaccess.

Solution

There are some solutions to solve the problem above. The easiest one is to use notepad to create the .htaccess file.

Open notepad and save the document with file name is .htaccess and save as type to All Files.

How to Restrict Access to Files or Folder on Windows XP

linglom — Mon, 08 Jun 2009 01:50:23 +0000

Introduction

You have a computer which share with others (friends, children, etc.). You’re using Windows XP and you need to customize permission of files or folders on certain users. For example, you want to restrict access your child not to access some folders which have your sensitive information. Or you may want to restrict access on disk drive D: to a certain user.

On Windows XP, you can customize either to allow or deny permissions on certain users or groups for a specific files or folders easily. But you need an administrative privilege to perform this task. So in the following section, I’ll show how to customize permissions of files or folders for certain users.

Customize permissions requires administrative privilege so if someone besides you has an account which has administrative privilege, he/she can also customize permissions of files or folders, too.

Note: You shouldn’t customize permissions on the system files or folders for example, Windows Folder (C:\WINDOWS), Program Files (C:\Program Files), Disk Drive C: (Windows System Drive), etc. If you remove permissions that are used by Windows system, the process or service that depends on it may error.

I wrote articles about reset administrator’s password years ago. So you should be aware that someone can gain administrative privilege and override your configuration. To prevent the situation, you have to restrict CD-Rom drive and USB drive to only trusted users because one of these devices is required to reset password.

Step-by-step

In the example below, I’m going to customize permissions to allow only “linglom” (a regular user) to access the folder C:\Restricted. And I have created another account which also a regular user “ling” who hasn’t the privilege to the certain folder to test access the restricted folder.

Login to Windows XP with an account that has an administrative privilege.
If your PC isn’t on a domain, you have to disable simple file sharing first. See
[Solved] Missing Security Tab on Windows XP for detail steps.
Select folder that you want to customize the permission. In this example, it’s C:\Restricted.
Right-click on the folder and select Properties.
On Properties window, select Security tab.
On Security tab, you can customize permissions on a certain user or group.
To determine if a name is a user or group, observe at icon in front of the name. If it’s a person, it will be a user. Otherwise, it will be a group.
By default, these permissions are inherit from root (C:\) which I don’t want it so I’ll remove the inheritance. Click Advanced.
Uncheck “Inherit from parent the permission entries that apply to child objects. Include these with entries explicitly defined here“.
The pop-up message appears, you have 2 options: Copy and Remove. In this example, I select Copy for ease of customization. If you select Remove, all permissions wil be removed so you have to configure it from scratch.
Now all permissions are customizable. You notice values on Inherited From columns are . Click OK.
Back to Security tab, remove Users (BKKTEST01\Users) by select the name and click Remove. This is the Users group which permissions are configured to allow access on this folder.
Next, add a local user “linglom”. Click Add.
On Enter the object names to select section, type “linglom” and click Check Names. It finds the account that match the name. Click OK.
Now I have an an user account “linglom” with default permissions (Read & Execute, List Folder Contents and Read) to this folder. Click OK to close the Properties window.
Test the configuration by login as “ling”, the account which hasn’t permission to access the permission customized folder.
Open My Computer -> C:\ -> Restricted. You’ll see the error message:
C:\Restricted is not accessible.
Access is denied.
Then, try again with the user account “linglom”.
You’ll see that you can open the folder and read files but you can’t create a new file or modify existing files on the permission customized folder. This is because that you didn’t give Write permission to the user account on step 15.

Summary

You should now get concept about permissions configuration. You can apply to customize permissions (Read, Write and Execute) to certain users on files/folders/disk drives. But keep in mind that if someone besides you has an account which has administrative privilege, he/she can also customize permissions of files or folders, too.

How to Silently Install Dot Net Framework 2.0 Using Batch File

linglom — Tue, 19 May 2009 06:57:12 +0000

Introduction

When you develop an application using Microsoft Visual Studio, it always requires Microsoft .NET Framework to be installed on clients in order to run the application but the required version may be vary depends on applications. Even third-party software around the world today are sometimes require Microsoft .NET Framework so you should install .NET Framework on clients at the first time you prepare them. But generally, there are computers which actively using by users and don’t have .NET Framework. Therefore, you should find a solution to install .NET Framework on clients without interrupt them. There are many solutions to solve the problem. In this post, I show how to silently install .NET Framework 2.0 SP1 on a local computer. The minimum recommend version is 2.0 Service Pack 1. Currently, the most updated version is 3.5 Service Pack 1.

Silently installation means that the software is installed in background so it doesn’t require any user interaction while it’s installing. It is a useful method for deploy software to clients without interrupt users.

First of all, you have to download .NET 2.0 SP1 from Microsoft. Then, I’ll show the command use to install in silent mode. After that, I create a batch file to run the command to make the installation easier.

Note: To install .NET Framework 2.0 SP1, it requires Windows Installer 3.1 to be installed first.

Step-by-step

Download Microsoft .NET Framework 2.0 Service Pack 1 from Microsoft.
- Microsoft .NET Framework 2.0 Service Pack 1 (x86) – 23.6 MB
- Microsoft .NET Framework 2.0 Service Pack 1 (x64) – 46.9 MB
On a client, open command prompt by Start -> Run -> type cmd -> press Enter.
Use /q parameter to install .NET Framework 2.0 SP1 in silent mode. Type “C:\NetFx20SP1_x86.exe /q”.
Note: The path to file of yours may not be the same as the example.
You won’t notice any dialog or user input message. But you can check if there is any error on the installation in Application Event Log. This is the example of the successfully installation message.
Product: Microsoft .NET Framework 2.0 Service Pack 1 – Update ‘.NET Framework CRT’ installed successfully.
Note: There are also other messages in the event log about the installation. This is just one of them.
You can also observe in Add or Remove Programs if .NET Framework has been installed or not. Click Start -> Settings -> Control Panel -> Add or Remove Programs.
Next, to make the installation more practical. I’ll move the installation file to a shared folder on \\192.168.125.12\MISC so you don’t need to copy the installation file to a target computer every time. Then, I create a batch file to execute the installation in silent mode so you don’t have to type the command every time.
The batch file will look as similar as below:
\\192.168.125.12\MISC\NetFx20SP1_x86.exe /q
Now I’ve tried to install the software by execute the batch file with a normal user credential. I have observed an error message below.
Setup discover the following problem:
You must have administrative privileges to run Microsoft.NET Framework 2.0 SP1 Setup. Please contact your system administrator.
The error message stated clearly that the current user doesn’t has privilege to install a software. To solve the problem, I use “runas” command to execute the installation as a domain administrator (virtual\administrator). Modify the batch file to be as below.
runas /user:virtual\administrator “\\192.168.125.12\MISC\NetFx20SP1_x86.exe /q”
Note: You can view the command reference by follow the link at the bottom.
Now try to run the batch file with a normal user credential again. It’ll ask for domain administrator’s password (the account which I’ve specified in the batch file). Type the password and press Enter.
Note: The password won’t show on the screen.
After a few minutes, observe the Application Event Log. You’ll see the message similar as the figure below.
Product: Microsoft .NET Framework 2.0 Service Pack 1 — Installation completed successfully.
Note: In user column, the user is virtual\administrator which isn’t the current user logon but it’s the user that I’ve specified in the batch file.
