Website on plesk windows Server asking for Username and password

Dedicated Server, Virtual Private Server, VPS Hosting, Web-Hosting, Windows Hosting

Website on Plesk Windows Server/Plesk VPS asking for Username and password.

I have recently purchased a Windows VPS with Plesk control panel and have uploaded website files. While visiting my website it is asking for username and password authentication. Now, I haven’t set any authentication on server for any website, what shall I need do?

This is quite common with the sites hosted on windows server with plesk as a control panel. You are not allowed to acces the site whtout authentication – entering username and password. This is not a bug or issue but is related to password synchronization with IIS server. To resolve this, you will need to synchronize the password.

Below given are some simple steps that you will need to follow:

  1. RDP to your windows server as an administrator.
  2. Start>Run>cmd [this will take you to sytem command prompt]
  3. cd to plesk\admin\bin [shortcut is cd %plesk_bin%]
  4. Type websrvmng.exe –update-anon-password –domain-name=yourdomain.com

The above command will synchronize the password and you will require no more password authentication to view the content.

If this doesn’t work for you, then please open a support ticket and we’ll investigate further and fix the issue for you happily.

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
‘–enable-gd-native-ttf’

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 :).

Clear-ssh-command-history-in-ssh-cache-from-server

Dedicated Server, Virtual Private Server, Web-Hosting

When I login to SSH and push the up arrow, the previous commands are shown. How do I clear or delete that log?

Clear the history for current login or current user.
#history -c

First find the history file for particular user.
Delete .bash_history file, will be recreated again next time.
#locate .bash_history
#rm .bash_history

It is not a best practice to totally disable the ssh command history on any dedicated server or vps server. It’s a quick reference to user’s past actions on server.

What is Virtual Server Hosting?

Virtual Private Server, Web-Hosting

VPS – Virtual Private Server

Virtualization is the hottest trend in the industry today, and the Parallels Virtuozzo platform allows for a highly scalable and full featured Virtual Private Server environment. Unlike hypervisor based systems, Virtuozzo allows all of the Virtual Machines on a physical server to share one underlying operating system. This makes much more efficient use of the physical infrastructure and allows for a greater density of Virtual Machines to run simultaneously.

Virtuozzo creates multiple isolated virtual containers (VCs) on a single physical server. Each VC performs and executes exactly like a stand-alone server to its users and applications. It can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.
