I have been having a lot of problems with my computer due to my teenagers accessing web sites that they should not be accessing. Despite my efforts of educating them on the viral consequences, they continue to follow their peers to these scumware infested sites. Is there a way to stop Internet Explorer from accessing certain sites?

Answer:

Yes, if you know which ones they are accessing, it is a pretty simple task. You can use the Windows ‘Hosts’ file to accomplish this, here’s how:

In Windows XP, the hosts file is found here:

C:\Windows\System32\Drivers\etc\hosts

Once you have found the hosts file, right click it and select Properties. Uncheck the “Read-Only” attribute (if checked). Click OK.

Double click the ‘Hosts’ file and select “Notepad” from the list of programs to open it with.

Once you have the hosts file open in Notepad, you will see an entry such as:

127.0.0.1 localhost

To block a certain web page from loading, add the following:

127.0.0.1 www.webpage.com

Your Hosts file will now look like this:

127.0.0.1 localhost
127.0.0.1 www.webpage.com

Add as many web addresses as you like in the same fashion.

Once you are finished, go up to ‘File’ and click ‘Save’.

The web pages listed in your ‘Hosts’ file should be blocked from access. It may be necessary for you to reboot your computer for these changes to take effect.

To view or to remove the Read-only or the System attributes of folders in Windows Server 2003 or in Windows XP
1. Click Start, click Run, type cmd, and then press ENTER.   2. To view the syntax for the Attrib command, type attrib /? at the command prompt.
Warning If you remove the Read-only or System attribute from a folder, it may appear as a ordinary folder and some customizations may be lost. For example, Windows customizes the Fonts folder and provides a special folder view that permits you to hide variations, such as bold and italic. It also permits you to change the folder’s view settings in ways that are specific to fonts. If you remove the Read-only and System attributes of the Fonts folder, these customized view settings are not available. For folders that you have customized by using the Customize tab of the folder’s Properties dialog box, the folder icon and other other customizations may be lost when you remove the Read-only attribute.
If a program cannot save files to a folder with the Read-only attribute, such as My Documents, change the Read-only attribute to System by using the Attrib command at a command prompt.
To remove the Read-only attribute and to set the System attribute, use the following command:attrib -r +s drive:\<path>\<foldername>For example, to remove the Read-only attribute and to set the System attribute for the C:\Test folder, use the following command:attrib -r +s c:\testBe aware that some programs may not operate correctly with folders for which the System attribute and the Read-only attribute are set. Therefore, use the following command to remove these attributes:attrib -r -s c:\test

Error Message:
Not resetting hidden file – filename
Explanation:
The specified files already had hidden attributes, so none of their attributes may be reset with the Attrib command unless you specify a +h or -h switch in the list of file attributes to change.
User Action:
Retry the command, adding the +h or -h switch to the list of attribute switches.

Nirvana – The Man Who Sold The World

After having developend and tested your website on a local server, the next big challenge is uploading the website to your web server, and updating the configuration such that you “go live”. The tutorial below gives you the steps required to move your Joomla website from your local computer to a server. With a few tweaks these steps also apply to moving Joomla from one host to another.

Upload all files to your web server

The first thing you need to do is transfer the files to the web server where your live site will be hosted. To be able to do this, you will need FTP (FTP is a way of allowing easy transfer of files across the web) access to your web server. FTP access typically consists of:

• FTP Address – typically this is something similar to ftp.yourdomain.com
• FTP Login details – username / password to access the ftp area

This information is given to you when you apply for a hosting account with any hosting company. To access the FTP area you will need an FTP client. A free and easy to use ftp client is FileZilla. Download and install this client and then enter the information to your ftp area. These should be similar to the image below:

Once you have connected to your webserver, upload all the files to the host. This is done by selecting all the Joomla files from your local hard drive and dragging them to the window which is connected to the host. This will start transfer of all your Joomla files to your hard disk.

Note: if you host has already installed Joomla for you, do not overwrite the configuration.php files. This contains very important details regarding the your Joomla host. You should keep a backup copy of this file. All other files can be overwritten, such that you have all the configuration you have done on the local installation.

Export / Import the Joomla database

Warning: the following steps about exporting / importing the joomla database are significantly technical. Please be aware of what you are doing because you may create a real mess.

The next step to tranfer the site you have created locally to the web server is the transfer of the Joomla database from your local MySQL, to the webserver database. This consists of two steps

• Exporting your current local database
• Importing the exported database to the MySQL database on the hosting company’s server

Export the local Joomla database

To export your current database you need to use the phpMyAdmin located on your local server and export the database. The phpMyAdmin URL differs depending on the local development server you are using. If you are using XAMPP to test and develop you website, you will find phpMyAdmin at http://localhost/phpMyAdmin

Choose the database which contains the website you want to upload, and export it to a file. This step depends very much on the phpMyAdmin you are using. However, there should be an Export link. Export all the tables. Once the database has been export to a .sql file, you should open the file with a text editor, and check that the file looks ok. It should contain the Joomla tables. Make sure there isn’t a Create database line. The database should be created manually.

Import to the hosting MySQL database

Once you have exported the database, you need to import on the host. Your hosting company should be able to provide you with access to MySQL. If you still haven’t created a database you should create it now. Take note of all details, especially the address of the server where the MySQL resides, the name of the database, username and password to access the database. If the Joomla database has already been created previously (using the Joomla installation procedure or otherwise) you should use the details given to you when creating the database.

Log on to the phpMyAdmin interface, find the import tab, and import the file you have exported above. Once again, the location of the Import link varies depending on the phpMyAdmin version being used, however this should be fairly intuitive.

Configure

Up to now, if you try to access your website, you will probably be given an error. This is because the configuration.php file you had on your local server does not contain the information related to your hosting account details. As stated previously, if your host has already installed Joomla for you, you should leave the configuration.php file created unchanged. Otherwise you will need to change the following critical details:

Joomla 1.5

• var $host = ‘localhost’; – this is the address of the server which is hosting your MySQL database
• var $user = ‘sqluser’; – this is the name of the username which will be used to access the Joomla MySQL database
• var $password = ‘p@ssw0rd’; – password for MySQL database
• var $db = ‘j15stable’; – MySQL Joomla database name
• var $log_path = ‘\home\logs’; – the path where any log files will be stored
• var $tmp_path = ‘\home\tmp’; – the path for tmp files

Joomla 1.0

• $mosConfig_host = ‘mysql.youhost.com’ – this is the address of the server which is hosting your MySQL database
• $mosConfig_user = ‘joomla_joomla’ – this is the name of the username which will be used to access the Joomla MySQL database
• $mosConfig_password = ‘password’ – password for MySQL database
• $mosConfig_db = ‘joomla_joomla’ – MySQL Joomla database name
• $mosConfig_absolute_path = ‘/home/xxxdomain/public_html/’ – this the absolute path to your Joomla installation. This differs from host to host so you will probably need to contact your host to ask for this. This used because there are a number of core files / components files which use other files. These files are imported or referenced using the exact path to the file. If this setting is not correct, you will get a File Does not exist error.
• $mosConfig_live_site = ‘http://www.your-domain.com‘ – this is used so that Joomla can create links links. If you want your site and links to have a www, then put http://www.your-domain.com, if you don’t want a www, the put http://your-domain.com. These settings need to be supported by your host.
• $mosConfig_cachepath = ‘/home/xxxdomain/public_html/cache’ – this is absolute path to the cache directory. The cache is used to increase the performance of your website. As you can see this is the same as the absolute path plus /cache (since this is the default directory where the cache files are stored.

Once all these entries in the configuration.php file have been given the correct values, Joomla should be able to access the database and code, and thus if you go to t
he address of your page, you should have a working Joomla website with all the customisation you have done. If not, one of the above settings is probably incorrect, or you might need to configure some settings further.

Test and secure the website

Go through all the website, to make sure that everything has been setup correctly. Since you should have uploaded the website, most of your settings should be correct. However, you might still have some minor configurations to do, so go through each page and area to test the everything is working correctly.

You should also take all the steps to secure your Joomla website.

The Easy Way Out

As you can see, the steps are fairly complicated and require quite some knowledge of various technologies. This is not something which should be attempted by someone who does not have experience or who does not understand what is going on. If you think these instructions are too difficult to follow, use a third party component which will do all the dirty work for you. A recommended tool for this is the JoomlaCloner component. This allows you to move your Joomla installation easily.

First to install joomla you need a webserver, php and mysql installed on your computer. If you don’t have these installed..download WAMP (Windows Apache MySql PHP) server and install it. I am writing this tutorial using WAMP
as my server. But these steps are almost same in all other servers.

Follow the steps below

1. First you need joomla package. Goto joomla website and download the latest version of joomla.
Follow this link download joomla. This tutorial is based on Joomla 1.5.x

2. unzip(extract) the file and rename it to joomla.

3. Then place it on www directory of the WAMP server.(or htdocs directory if you are using XAMPP server)

4. Now type http://localhost/joomla on your browser address bar. You’ll see the installation page of joomla…

5. select your language and Click on next.

6. you’ll see a pre-installation check page. Click Next.

7. You’ll see the licence page. Click Next.

8. Database(MySQL) configuration page.

Database type: leave it mysql

hostname: type localhost

username: type root (or your mysql username)

password: type password of your mysql account (the default is empty for root)

Database name: type joomla (or anything you wish)

(Now the database joomla will be automatically created in your mysql.)

Click Next

9. Ftp configuration page. Leave it and click Next.

10.Main configuraion page.

Site Name: anything you like

Your email: type your email address.

Admin password:type any password you like (this will be the password for the admin account)

confirm password: type the above password again.

Next, click on Install Sample Data. You’ll see Sample data installed successfully.

Click Next.

11. Finish…. Now go to “joomla” folder in www directory and delete the “installation” folder. This is for security reasons.

Note: If you don’t delete the installation folder, you can’t access joomla home page.

Success…Now type http://localhost/joomla in your browser and you’ll see the joomla home page.

Editing the content..
Login as the administrator.
To login as administrator go to http://localhost/joomla/administrator.

You’ll see a login page. Type “admin” as username and type in your admin password you used at registration. Now you will see administrator page. Now you can edit cms, install templates and extesnions etc…

Installing Templates and extensions:
In the administrators page, move your mouse over exentsions link, you’ll see a drop down menu. Select “install/uninstall”. Extension manager will open. You can upload templates and extensions from this page.

After installing a template….go to Extensions at the top….and click on Template Manager from the drop down menu. Now select the template you install and click on “default” to make it the default template.
