Another way to share files between Ubuntu and Windows

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). AddThis

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! AddThis

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! AddThis
