Another way to share files between Ubuntu and Windows
2 Replies
This tutorial will show you another way to share and to access the network share folders between Windows and Ubuntu machines. When file sharing is enabled, both systems can access files and folders on any of the PCs. Users with accounts on Ubuntu systems will also be able to access the content directly from your home.
1. To begin, you will need to log on to your Windows operating system. Click ‘Start’ -> search for ‘Network and Sharing Center’ and click on it.
2. Access the ‘Change advanced settings sharing. ” option.
3. Enable file sharing and backup as well.
4. At this point, you need to switch your operating system to Ubuntu. Once you log in, click on ‘Ubuntu menu -> System Tools ”
5. Then select ‘Ubuntu Software Center. ”
6. Find and install ‘Samba‘. This software is required for a better compatibility between the two operating systems.
7. After Samba is installed, you should go to ‘System → Administration –> Samba’.
8. Then click ‘Preferences -> Server Settings’.
9. Write the name of the workgroup you set for your Windows PC(s). If you do not know the exact name because you did not set it, the default name for Windows Workgroups is set to ‘WORKGROUP‘ (capitalizing is not required, however, since Windows is generally not case-sensitive).

How to manage the GRUB and purge old Kernel versions on the start-up menu
After a kernel update, you find the start-up menu populated with extra lines related to all the old kernel versions plus the current one. To manage the start-up manager and safely remove old kernels you have to manually operate on it.
First of all you have to double-check what is the current kernel version.
Open a Terminal and type:
uname -r
The result will be something similar to: 2.6.32-35-generic
Then you will go to the boot directory through the command:
cd /boot ls vmlinuz*
The next step will be to obtain more information about old kernel you have on our PC:
ls vmlinuz*
Now in the Terminal you have results similar to these:
vmlinuz-2.6.32-21-generic vmlinuz-2.6.32-25-generic vmlinuz-2.6.32-35-generic
vmlinuz-2.6.32-24-generic vmlinuz-2.6.32-26-generic
As last step you have to remove all the old version of the kernel using this command:
sudo apt-get remove linux-image-X.X.XX-XX-generic
where “x” is the obsolete kernel version you want to purge. In my specific case the proper command line I used was:
sudo apt-get remove linux-image-2.6.32-21-generic linux-image-2.6.32-24-generic linux-image-2.6.32-25-generic linux-image-2.6.32-26-generic
Last but not least go to System –> Administration –> StartUp Manager (available for installation on Synaptics or on Ubuntu Software Center) and select your OS choice in the Default Operating System menu. That’s all!

Fix .ICEauthority problem at Linux boot up
After upgrading my Ubuntu 10.04 LTS I had an error window at every boot up session. The message advised me about:
Could not update ICEauthority file /home/username/.ICEauthority
ICEauthority is the Inter-Client Exchange (ICE) Protocol that allows authentication, negotiation, setting up and taking down connections between programs. In few words, if two programs have the same cookies, they will talk and exchange data through ICEauthority.
To fix this matter open the Terminal and type:
ls -al
Then you find a line similar to this:
-rw——- 1 root root 35226 2011-10-06 00:24 .ICEauthority
This means that your profile (username on a Linux OS) is not allowed to manage ICEauthority and you have to gain full permission to solve the boot up problem:
sudo chown username:username ~/.ICEauthority
Where username is your user profile on Linux.
Then type:
sudo chmod u+rw ~/.ICEauthority
To check if you succeeded, type again:
ls -al
and this time you will find a line like this:
-rw——- 1 username username 35226 2011-10-06 00:24 .ICEauthority
That’s all!

How to Change the Boot Order in Ubuntu
If you installed Ubuntu and Windows at the same time, you probably noticed that when you start your computer you can choose what operating system to launch. The responsible software for this is usually the GRUB loader and its menu. Obviously, after you install Ubuntu, it is placed as the first option and if you do not explicitly choose Windows in a few seconds, Ubuntu will be started. But what if you want Windows as your default option? Here is how you change the order:
1. Launch a new Ubuntu Terminal (Applications, Accessories). Type in the following command:
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst_backup
This will create a backup of the GRUB configuration file.
2. Now open the file. We’ll do it with a new command:
sudo gedit /boot/grub/menu.lst
You will be prompted for a password, after which a text editor will be launched. In most of the situations, the menu.lst file contains many comments. You have to search for a line that says
default 0
This should not be very far from the end of file. Here you will have to intervene. After a few lines you will the variable called ‘timeout’ and its value (10 by default). If you want to have more or less time available for choosing your operating system, change the 10 with what number you want.
So back to the boot sequence. Scroll through the file again until you find:
title Ubuntu, kernel 2.6.17-10-generic
There will be more titles. Count the order number of Windows, but start from 0. The value you choose should overwrite the default one. For example, if Windows is the 4th title in the list, you will need to type
default 4
instead of ‘default 0’, which was described above. All you need to do at this point is to save the file and restart your computer.
Unetbootin: a revolutionary multiplatform (Linux and Windows) software to create bootable Linux USB OS (and not only…)
This week, in our Linux Page (in Spanish), we have described UNetbootin: a powerful software which allows you to install many different Linux OS (Ubuntu, Fedora, openSUSE, CentOS, Debian, ArchLinux and many others) on a bootable USB key. The use of UNetbootin is really simple and after a couple of tests everyone is able to create his/her own portable OS on USB. Moreover can be used to easily install a new Linux OS directly on the local hard disk. In fact, this software properly manages Linux and Windows bootloader without causing side effects. I personally recommend UNetbootin to all the people who always desires testing the last OS versions and do not want to install them directly on their PC. Last but not least, UNetbootin is available in the followiing languages: English, Spanish, Russian, Portuguese and Hungarian. Easy, useful tool!
