To convert the .DMG file to an ISO image, type the following command at your terminal window in MAC:

hdiutil convert /path/to/source.dmg -format UDTO -o /path/to/target.iso

Replace “/path/to/source.dmg” with the path and name of the existing .DMG file, and replace /path/to/target.iso with the desired path and name for the converted image.

The process above creates a file at the target location specified called “target.iso.cdr”. Rename this to .iso (just remove the trailing .cdr) and you should have a working .iso!

You can use this ISO image to burn in any CD/DVD burning software on Windows or Linux.

1. Create a new virtual disk
2. Clone the old disk to this newly created virtual disk
3. Disconnect the old disk via storage settings in Virtual Box
4. Connect/Attach the new disk to the Virtual Machine
5. Boot up using the new disk
6. Go to Windows Computer Management and Extend the disk space

Let’s go each step in a bit of detail now.

1. Create new virtual disk via Settings –> Storage. Make sure you choose enough size as per your requirements when creating this new disk. Choose Dynamically expanding storage for the disk storage type.

C:\VirtualBox>
C:\VirtualBox>VBoxManage clonehd [OldHDDFile.vid] [NewHDDFile.vid] --existing
C:\VirtualBox>

4. Connect/Attach the new disk to the Virtual Machine

This problem was noticed when using Glossy Accordion Menu version 1.9 in Google Chrome browser only. Works fine in Firefox and IE.

Solution:

Add “display:block” to the Accordion CSS

.glossymenu a.menuitem .statusicon{ /*CSS for icon image that gets dynamically added
	position: absolute;
	top: 7px;
	right: 7px;
	border: none;
	display:block; /* adding this should fix the display issue in Google Chrome browser */
}

Now the problem:

The Flash movie was still showing on top of the Colorbox window. It sort of worked fine on Firefox and Chrome but in IE 8 (IE 9 was fine) the problem was particularly prominent as the whole of the Flash movie sat on top!!

Solution:

A quick search in Adobe Flash docs, I found that there is a parameter called WMODE that controls how flash movie behaves when interacting with other HTML elements.

• WMODE – Possible values:
• Window
• Opaque
• Transparent – Sets the Window Mode property of the Flash movie for transparency, layering and positioning in the browser.
• Window – Movie plays in its own rectangular window on a web page
• Opaque – Movie hides everything on the page behind it
• Transparent – Background of the HTML page shows through all transparent portions of the movie, this may slow animation performance

Example:

<object .....>

.....

<param name="wmode" value="transparent">

.....

<embed ..... wmode="transparent" .....>

</object>

And voila!! Perfect result.

Well the situation could be described as:

• CentOS 5
• vsFTPd as FTP server
• FileZilla as FTP client
• Connected ok to FTP server via the FileZilla client
• Try to make a file transfer to FTP server but that fails!!

Well first thing is to check for directory permissions that they allow files to be created. If all seems in order, it may be that SELinux is in action and not allowing the transfer.

Try the following command – this will allow user home directories to receive files.

setsebool -P ftp_home_dir 1

You could even temporarily disable SELinux just to find out if this is the cause of FTP failing to transfer files.

How to disable SELinux permanently

In Fedora Core and RedHat Enterprise, edit /etc/selinux/config and change the SELINUX line to SELINUX=disabled:

• This file controls the state of SELinux on the system.
• SELINUX= can take one of these three values:
• enforcing – SELinux security policy is enforced.
• permissive – SELinux prints warnings instead of enforcing.
• disabled – No SELinux policy is loaded. SELINUX=disabled
• SELINUXTYPE= can take one of these two values: # targeted – Only targeted network daemons are protected.
• strict – Full SELinux protection. SELINUXTYPE=targeted

and then reboot the system.

Installed the NAS drive, created shared areas, configured a DLNA server etc etc. All went fine. Now the moment of truth – would I be able to successfully run VMs that reside on NAS?

Setup was as follows:

• Windows 7 Prof
• VMWare Player 7.0.1
• Buffalo LinkStation NAS
• All connected through LAN

Launched one of the VMs by double clicking the .vmx file. All fine so far, VM Player kicks in and starts to load, but then the following error was thrown:

Here’s how to fix it:

• Edit your .vmx file with your favorite text editor
• Add a line to the end of this file:
• diskLib.sparseMaxFileSizeCheck="FALSE"

Now fire up the VM again and hopefully it should work as normal!

Looking at logs on server it displayed messages like “using NTLMv2 logon, not valid with passthru authentication”.

Here is how to solve this:

• Launch Windows 7 Group Policy Editor (gpedit.msc)
• Go to Computer Configuration -> Security Settings -> Local Policies -> Security Options
• Look out for “Network Security: LAN Manager Authentication Level”
• Try changing it to “Send LM & NTLM and V2 if Negotiated”

Good luck!

• OS is CentOS at both ends
• You have necessary access right to use shell account on both ends

Mainly there are three steps:

1. Generate Public/Private key pairs on Local machine. Make sure you generate the correct type of key pair to be used on the remote server. In this example, I will use a “dsa” key pair.
   • ssh-keygen -t dsa – Use this command to generate the key pair. For our purpose, you can just accept the default values for any prompts the command throws at you!
   • Generated keys will be stored at ~/.ssh directory (your home directory/.ssh)
   • ls -l ~/.ssh – Use this command to view the generated keys. Public key is the file that has a .pub extension. File names are the ones you specified during the key creation process above
2. Local server setup
   • Change permissions as follows:
     • chmod 700 ~/.ssh
     • chmod 600 ~/.ssh/*
   • Create a file called “config” in ~/.ssh directory and enter the following text in it
     • Host <FRIENDLY_SERVER_NAME>
     • HostName <MACHINE_IP_ADDRESS>
     • IdentityFile ~/.ssh/id_dsa
     • PasswordAuthentication no
     • Port <SSH PORT usually 22 but use yours if you have setup a diff port for ssh>
     • User <USER_ID/NAME_ON_REMOTE_SERVER that you will be connecting as>
   • chmod 600 ~/.ssh/config – Use this command to set correct permissions

Note: Use correct values in place of placeholders in <> above

3. Remote server setup
   • Copy the public key file you generated on your local machine to the remote machine’s .ssh directory. Use any method that suits you but the following command will do the trick as well.
     • scp ~/.ssh/id_dsa.pub username@servername:~/.ssh
   • Log in to the remote machine. Use your favourite SSH client or the following command from local server prompt.
     • ssh username@servername
   • Append the contents of your public key file to ~/.ssh/the authorized_keys file. Again feel free to use any method but the following command will also do the job.
     • cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
   • You can now delete the .pub file if you like but doesn’t do any harm if left there.
   • Set Permissions
     • chmod 700 ~/.ssh
     • chmod 600 ~/.ssh/*

The system is now setup!! Try the follwoing command on your local machine and if all goes well, you should connect to the remote server without having to enter a password.

ssh username@servername

Note: If you are using non-standard port for SSH, use the following command instead:

ssh -p <YOUR_SSH_PORT_NUMBER> username@servername

There are two ways to achieve this (PrestaShop Ver 1.3.7.0).

1. Use the following SQL commands using any of your favourite front end (or even the commands line) to the PrestaShop database.

DELETE ps_cart_product
  FROM ps_cart_product
   JOIN ps_cart ON ps_cart.id_cart = ps_cart_product.id_cart
WHERE ps_cart.id_customer = 0
    AND ps_cart.id_guest = 0;

DELETE FROM ps_cart WHERE ps_cart.id_customer = 0 AND ps_cart.id_guest = 0;

2. Modify the Back Office interface for Carts to allow interactive deletes

a) Edit admin/tabs/AdminCarts.php
b) Find $this->delete = false; and replace with $this->delete = true;
c) Go to Carts in Back Office and you should now see check boxes against the carts. Select and delete the ones you want to.
