Including a Ubuntu Machine into a Windows Domain

One of the great problems of interoperability between Linux and Windows has been the impossibility of Linux systems for joining a Microsoft Windows network. Subsequently, several standards to achieve this were developed over the years (see Samba), but they were far from offering normal user the chance to achieve this easily.
The infrastructure of many companies around the world, of all sizes, also relies on the use of a Windows domain. In all companies, one priority always stands out. That is to reduce information costs and expenses. Because of this, many of them have opted for the use of computers with Linux operating systems. But in many cases their integration into Active Directory environments was a problem.
Recently, a new tool was created to facilitate the full integration of a Linux system in an AD environment. And as far as today, it seems very promising. Thanks to likewise-Open5 (http://www.likewiseopen.org/), the difficulty of integration is almost null.

The following lines will illustrate the inclusion of Ubuntu in a Windows domain via likewise-Open5.

Installation

Likewise-Open5 Installation process is very simple. It can be done both through the graphical environment and command line. We will use the second variant. Therefore, a new terminal window must be open, in which you specify the following command:

sudo apt-get install likewise-open5

This command should resolve all the dependencies necessary to prepare the machine to be integrated in the Windows domain.

Adding a new machine

To actually add the machine, specify the following command in the terminal window:

sudo domainjoin-cli join domain used

Where DOMAIN is the area used for integrating the machine, and USER is the username that has the corresponding rights. You will be asked for your user password, and once successfully logged in, you are officially added the desired machine.

In Windows 7, you can click and drag a window to the left or right edge of the desktop and it will fill half of the screen, or snap a window to the top edge of the desktop and it will be maximized.

In Ubuntu, you can click and drag a window to the left, right or top edge of the desktop to achieve the same result.

In addition to CompizConfig Settings Manager, install WmCtrl if not added:
– go to Applications (or Main Menu) > Accessories > Terminal.
– enter sudo apt-get install wmctrl
– enter password when prompted.
– go To System > Preferences > CompizConfig Settings Manager.
– select “General” from the left panel and click “Commands”.
In Command line 0, 1 and 2, paste the following codes:

Command line 0, paste:

WIDTH=`xdpyinfo | grep ‘dimensions:’ | cut -f 2 -d ‘:’ | cut -f 1 -d ‘x’` && HALF=$(($WIDTH/2)) && wmctrl -r :ACTIVE: -b add,maximized_vert && wmctrl -r :ACTIVE: -e 0,0,0,$HALF,-1

Command line 1, paste:

WIDTH=`xdpyinfo | grep ‘dimensions:’ | cut -f 2 -d ‘:’ | cut -f 1 -d ‘x’` && HALF=$(($WIDTH/2)) && wmctrl -r :ACTIVE: -b add,maximized_vert && wmctrl -r :ACTIVE: -e 0,$HALF,0,$HALF,-1

Command line 2, paste:

wmctrl -r :ACTIVE: -b add,maximized_vert,maximized_horz

In the same window, click “Edge Bindings” tab.
Change Run Command 0, 1 and 2 from “None” to “Left”, “Right” and “Top” respectively.
Click “Back” button and select “General Options”, change “Edge Trigger Delay” to about 500.

Set Aero Glass Effect in Ubuntu

Leave a reply

In Ubuntu you can set nearly the same aero glass effect to window borders with alpha transparency as available in Windows 7:

– press Alt+F2 to bring up “Run Application” window.
– type gconf-editor into the box, click “Run” to bring up Configuration Editor.
– browse to apps > gwd, look for “metacity_theme_active_opacity” on the right panel.
– change the value in “metacity_theme_active_opacity” from 1 to 0.75 (or smaller such as 0.5 for more transparency).
Then go to System > Preferences > CompizConfig Settings Manager:
– select “Effects” from the left panel.
– tick “Blur Windows” and click the “Close” button. (Note: default values in Blur Windows can be applied.)
Note: If the aero glass effect doesn’t work, check if you have updated your display driver. To check, go to System > Administration > Additional Drivers, activate the recommended graphics driver and restart the system.

It also has extra features such as rss news and podcast support, remove duplicates, easy notes editor (with multipage support), songs synchronization, playlists export, a built in music player and much more. It has been translated in 12 languages.

On Linux, the installation is really simple:

make sure you’ve used iTunes at least once (under Windows or Mac OS X)

have at least one song on iPod

copy the libfmodex audio library to /usr/lib (you need root privileges). You’ll find this file in the package you’ve downloaded

mount your iPod somewhere inside /mnt or /media with read/write access

make sure you have the df command installed, which is usually part of any standard linux distribution.

To run YamiPod just double-click on YamiPod’s binary.

Using YamiPod is also so simple when you want to Copy Music to iPod: Drag&drop files into the song listbox. You can even drag and drop folders, YamiPod will add all valid music files found in sub folders.

In Playlist tab you can select:

Destination: select a playlist where to add all dragged songs.

Lyric filename: how lyric should be named.

Create playlist from folder: this will add all songs in a folder to a playlist named as the folder. For example if you dragged a folder called Music with 2 subfolders: 70’s and 80’s containing various files. Files in 70’s will be added to a newly created folder called 70’s. Files in the other folder will be added to a playlist called 80’s.

In Advanced tab you can select:

Auto capital first letter: will titlecase all song tags.

If duplicated: what to do if song exists on iPod.

Get song info by path and filename: if your song tags are missing but you named and placed your song following a particular order, you can tell YamiPod to get song tags out of filename a path.

Tips:
Holding SHIFT while dragging will add songs to currently selected playlist. If you’ve selected multiple songs to add you can quickly edit next (previous) song information by pressing ALT+down (up).

Computer networks are sometimes comprised of various OS and while operating a network made up fully of Ubuntu desktop and server computer systems would definitely be enjoyable, some community environments can consist of both Ubuntu and Microsoft Windows systems working together.
If you want to make an Ubuntu shared folder be accessible to Windows XP, run the NTFS configuration tool on the drive.
Don’t forget that it is advisable to have admin rights to do that modification.
Select application->Accessories->Terminal
then type the following:

sudo gedit /etc/samba/smb.conf

and in the [global] section add the following line:

To enable remote desktop on a VirtualBox machine, you have to follow these steps:
VBoxManage modifyvm MachineName -vrdp
This command enables rdp on the virtual machine
VBoxManage startvm MachineName -type vrdp

It starts virtual machine, listening for rdp request on port 3389 (default port)
rdesktop-vrdp localhost

Connects virtual machine with rdp (You can use rdesktop too).
If you want to change rdp port, use this command:
VBoxManage modifyvm MachineName -vrdpport

Also, enabling authentication for rdp is possible:

Get Kindle for PC to Ubuntu (if you really don’t like Calibre)

1 Reply

Amazon’s Kindle a popular portable e-book reader device, lately made Kindle for PC application that allows you to download and have books on your computer rather than having a portable e-book reader device. There’s only Kindle Windows version but the nice thing is you can have this application in Linux.
This is tested in Ubuntu 9 running Gnome. You can use different version of Linux, but first you must have Wine HQ installed to you computer. Then download the EXE file of Kindle for PC application in Amazon.
Install this with Wine HQ software loader and proceed to the normal installation, the same thing that you do in Windows environment.
Note:

– At your first run you won’t see anything at all

– Configure Wine first and add Kindle for PC as an application and make it run in Windows 98 mode

– If it won’t work, change to other mode

– When it opens successfully you have to input you Amazon email add and password to register the software.

But, please, don’t forget that if you prefer open source software, you can directly use Calibre, a powerful free software we posted a while ago.

LibreOffice vs. OpenOffice! What’s the difference?

9 Replies

Since the end of September 2010, a group of German OpenOffice volunteers left definitively the project to join the The Document Foundation and develop a fork version of the famous free productivity platform now controlled by Oracle. After just few months we have LibreOffice: a (more or less) new cross-platform productivity software based on OpenOffice version 3.3 beta. We compared both the free suites and apparently we did not notice particular differences in features and tools. Also the graphic interface is similar between the two platforms and the buttons position is the same. At the moment LibreOffice supports less languages in its Linux and MAC OS X versions and it is not compatible with Solaris based PCs. Both the productivity platforms are able to use the OpenOffice extension library. Consequently, it is clear that it’s too early to notice relevant technical differences between the two competitors but, for sure, something will show off in the next versions. In fact LibreOffice has been created to guarantee a vendor independent office suite which can be developed with no copyright software chunks. The goal is prestigious and we can only say, Good Luck LibreOffice!
