Important factors about domain name registration.

A factor by factor quality analysis of the domain name, as an example, is given below. Useful for website appraisals, and buying and registering domain names.

1. Length

Unichost is a 8 character word. Shorter words make better domain names. At 8 characters should make a good domain name.

Captcha image is not working – Fatal error?

Captcha image is not working – Fatal error?

You have the GD image library installed and otherwise working.
Still unable to get captcha with the captcha plugin.

You are not sure what’s the problem as it works on one of your other sites.  When you try to include the captcha on your website or contact form it generates an error message like…
Call to undefined function imagettftext() OR
Fatal error: Call to undefined function imagettftext() in /home/user/public_html/appfolder/plugins/captcha/captcha.php on line 99  OR
Fatal error: Call to undefined function imagefttext() in /home/user/public_html/lib/captcha/captcha.php on line 329 OR

Problem could be, because the standard PHP “imagefttext()” function does not work on your server.
It can caused by the fact that there is no –enable-gd-native-ttf key installed on your server as the Cart uses GD Library for displaying the verification image.

Please note that PHP must be configured with the following keys:
–with-gd –enable-gd-native-ttf  Contact your host to make the change!

Any idea why or how it can be fixed?

imagettftext() is part of the GD image functions library, which is not always part of PHP (the code CMS/Cart runs on).
You need to contact your host and ask them to install the PHP GD library. It’s really simple for them to do and is fairly common, so if they give you a hard time about it, I would seriously consider switching to better and friendly host – UnicHost :).

FLUSH DNS in Windows Linux Mac OS

Filed under: Web-Hosting,www — Unichost @ 5:33 am

FLUSH DNS in different platforms

In Microsoft Windows, you can use the command flushdns to flush the DNS resolver cache.
Open the command prompt and type the following:
C:>ipconfig /flushdns
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.

In Mac OSX Leopard, you can use the command dscacheutil -flushcache to flush the DNS resolver cache:
bash-2.05a$ dscacheutil -flushcache

In Mac OSX versions 10.5.1 and before, the command lookupd -flushcache performed the same task:
bash-2.05a$ lookupd -flushcache

In Linux, the nscd daemon manages the DNS cache. To flush the DNS cache, restart the nscd daemon.
To restart the nscd daemon, use the command
#/etc/init.d/nscd restart

Filed under: Dedicated Server,PHP,Scripts,Setup,www — Tags: , , — Unichost @ 6:42 pm

How to check php settings by using phpinfo on server?

Each server is setup differently whether it is a dedicated server or a virtual server, phpinfo() is commonly used to check configuration settings and for available predefined variables on a given web server.

phpinfo() is a valuable debugging tool as it contains all the data, information related to environment, GET, POST, Cookie, Server etc.

To create the file simply add the following lines of code to a blank document.

Save the file as phpinfo.php and place it in the desired directory. Lastly, call the script from a browser.

This php file will output detail information about the current state of PHP: PHP compilation options and extensions, the PHP version, server information and environment, the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License as well.

how to use ftp client with your web hosting account

Filed under: Ftp Server,Transfer,Web-Hosting,www — Tags: , , — Unichost @ 1:50 pm

Tutorial to use FTP Client, CoreFTP with your web hosting account.

In this ftp tutorial we will assume that you own the domain ‘’ and your FTP username is ‘’.

Follow these steps to complete the ftp tutorial:

1. Get ftp client from CoreFTP website:
2. Once you install CoreFTP, open it up. You should now see the ‘Site Manager’. Your screen should look like this:

FTP Site Manager

This is the screen where you enter your web hosting account information.

[Note: This is just an example, not your actual username and password.]

  • Site Name: yourdomain
  • Host / IP:
  • User Name:
  • Password: yourftppassword
  • If you are behind a firewall, enable Passvie Mode, by checking the ‘PASV Transfers’ checkbox.

To connect to the server, click on the ‘Connect’ button. And you are done.

Once the FTP program makes a successful connection, the left pane will show files/folders on your computer, the right pane will shows files/folders on the FTP site / remote web server.

Where, in which folder to upload your website files?

On Linux server /cPanel Hosting account, you will be able to see ‘public_html’ or ‘www’ folder in the right view.
On Windows server /DotNetPanel Hosting account, it will be ‘wwwroot’ folder.

Please note that index.html or index.htm or default.html or index.php or index.asp [windows only] file acts as your homepage. Whenever a visitor types in UnicHost Web Server will look for one of the file first and will load homepage of your website.

Facing FTP connection problems?

1. If you just obtained your web hosting account at UnicHost then your domain may not be ready to start using our service. So, in this case, instead of using your domain in the ‘Host or URL’ box you should use the IP address given to you in your welcome e-mail.
2. It may be that you are behind a firewall and/or router and need to use passive FTP. Check step 2 to see how to enable passive FTP.

Once the FTP program makes a connection, you will be able to see/browse files and folders in the right view.

Any further help, we are there for you. Call us or open a support ticket at support [at]

What is the difference between www and public_html ?

Filed under: Web-Hosting,www — Tags: , , , — Unichost @ 2:01 pm

Is there any technical difference between www and public_html?

Actually, there is no difference between www and public_html. Technically, the default directory created to upload your web files is public_html. To make it more user friendly and understandable – www, the symbolic link is created (it is like a desktop shortcut) that points to the same folder. Upload your website related content to one of these folders, it doesn’t matter at all.
