The L D ightweight irectory A ccess P rotocol (LDAP) has to authenticate Internet user worth in. LDAP provides for a very high-performance access to Directory Server (LDAP server also called) in which user data are stored hierarchically.

To deal with the issue a bit more, you have to put on not just their own LDAP server, but can draw on a range of public and free LDAP server.

A good list of this is the eMailman . A simple query using ldapsearch (part of MacOS, with Ubuntu, the package must be installed ldap-utils) might look like this:

 "ldap.uno.edu" -LLL -x \ -b "ou=Students,o=UNIVERSITY OF NEW ORLEANS,c=US" \ "(sn=Fu)" cn dn: cn =Pik Yu Fu, ou =Students, o =University of New Orleans, c =US cn: Pik Yu Fu dn: cn =Yuanyuan Fu : yfu2, ou =Students, o =University of New Orleans, c =US cn: Yuanyuan Fu : yfu2 dn: cn =Shiquan Fu, ou =Students, o =University of New Orleans, c =US cn: Shiquan Fu > Ldapsearch-h "ldap.uno.edu"-LLL-x \-b "= Students, O = UNIVERSITY OF NEW ORLEANS, c = U.S." \ "(sn = Fu) cn dn" ou: cn = Pik Yu Fu , ou = students, o = University of New Orleans, c = U.S. cn: Yu Fu dn Spades: cn = Yuan Yuan Fu: yfu2, ou = students, o = University of New Orleans, c = U.S. cn: Yuan Yuan Fu: yfu2 dn : cn = Shiquan Fu, ou = students, o = University of New Orleans, c = U.S. cn: Shiquan Fu 

This query searches the LDAP server of the University of New Orleans to students with last name Fu. Here is a brief explanation of the parameters:

-H

LDAP Server

-LLL

Output options - an easy-L restricts the output to LDIFv1. A second-L suppresses comments. A third-L suppresses the output of the LDIF version.

-X

Use the simple authentication without the Simple Authentication and Security Layer (SASL).

-B

Use a different search base as a starting point for the search.

(Sn = Fu)

Filters to search by last name

cn

Common name - attribute that is spent

Who the dock and under MacOs like it in other operating systems like to have, which is at least for Gnome-based Linux distributions, a solution offered.

The program launcher gnome-do with the theme Docky brings the dock of MacOS on the Gnome desktop. Is particularly easy to install in Ubuntu.

Gnome-do is already included in the repositories and can be:

  sudo apt-get install gnome-do 

be installed. The currently included in the package source version is 0.61. Whoever wants to be the last stand on, should be repositories of the project involve the.

  intrepid main intrepid main deb http://ppa.launchpad.net/do-core/ppa/ubuntu
 intrepid main deb-src http://ppa.launchpad.net/do-core/ppa/ubuntu intrepid main 

What has to be observed, one can in the installation instructions read.

The dock Docky is an issue of gnome-do. It must be under " Preferences -> Appearance to be enabled. Docky appears, however, this selection only when either the desktop effects are enabled ( System -> Einstellungen -> Erscheinungsbild -> visuelle Effekte ), or the effects of Metacity were activated.

The latter can be with the command line:

  bool \ gconftool-2-s - type bool \ 
 metacity / general / compositing_manager true / Apps / metacity / general / compositing_manager true 

. Switch It should be noted that only the desktop effects or Metacity effects should be used because they interfere with each other themselves.

Conclusion: Gnome-do and Docky is starting applications not only simple, but beautiful. I like KDE even a trailer, as I do.

It is amazing that one of such useful tools as mytop late attention is even more so. It is that Mysql Monitoring Tool mytop a true jewel for all of us who are not from the command line can be a deterrent itself.

Mytop shows all the data on the performance, the threads currently executing SQL queries and the MySQL database server. The data are similarly processed and, as with the top command line tool (for processes).

Mytop is available for Windows, Mac and Linux. Under Ubuntu you can install it easily with apt on.

  sudo apt-get install mytop 

After installation you can start either from the command line mytop

  -p < passwort > mytop-u <username>-p <password> 

or the user name, password and other parameters in the configuration file ~/.mytop deposit.

As already reported me severely disappointed Parrallels 3 and had therefore Virtualbox virtualization solution as soft. What to consider when installing, I would like to hand briefly at this point.

The first thing you should to install Kubuntu a current ISO image from the download section to download.
Then we created a new virtual machine under Virtualbox and indicate in the dialog the downloaded Kubuntu cdrom image. In the audio dialog you should absolutely choose Core Audio, as the speakers remain silent otherwise. Otherwise, I'm done with the settings in the screenshot visible good experience.

After starting the virtual machine (VM) it then goes through the normal installation routine of Kubuntu. If one is finished, you can then remove the ISO image from the cdrom set the virtual machine.

To change the screen resolution and a better mouse control can be to have you install the Virtualbox Guest Additions. When you select this menu item from the Device menu, you can then embed the item on CD / DVD-ROM devices VBoxGuestAdditions.iso the ISO image.
Another prerequisite is the Kubuntu package build-essential. The easiest way to install via the command line (Terminal) within the VM using apt.

  sudo apt-get install build-essential 

Are all the preparations can be left open at the same command line to mount the CD and run the installation script with root (administrator) privileges. Thereafter, the virtual machine durchgestartet.

  media / cdrom0 sudo mount / media / cdrom0
 media / cdrom cd / media / cdrom
 VBoxLinuxAdditions-x86.run sudo. / VBoxLinuxAdditions-x86.run 

What then remains is to make Kubuntu multimedia capable, that is:

• Install Flash [5]
• mp3 support installed. This one calls best on an mp3 file and follow the instructions

VirtualBox also offers the possibility of shared folders. Installation is a bit tricky [4] but, in my view totally unnecessary as there is a better alternative and that the network folder that you can build up over ssh (secure) of Kubuntu on Mac.

The only prerequisite is an ssh server on the Mac, which is included in MacOS Leopard and System Preferences> Sharing> Remote login can be activated. Once done, you can add under Kubuntu in the file manager (Dolphin) in the network share point. As you type must then secure shell (ssh) select and specify the IP address of the Mac yet, Benuterzname and password, and the path to home directory (or any other folder).

Done!

Conclusion: How much more difficult to install a VM under Parallels than under Virtualbox, I can not say. The fact is, however, fits that to a free operating a free virtualization solution much better.

What do you think?

No - or at least I have not yet found where it goes.

The problem is this. The installation is so easy that you will be thrown only when they first log into the cold water. Once KDE4 start attempts, the shaky video mode and starts the X server. The KDE Window Manager kdm gets into an endless boot-crash-crash-boot loop [1]. That does look fun with the first few times, but loses quickly in entertainment value and there remains nothing but frustration.

How well that Parallels has just launched the new version 4 out, but this can be paid with 40 €. Now it is so that I swear by my Mac purchase I did not want to annoy more than software. So I did back then € 70 for Parallels Desktop loose, although at this time virtualization on Windows and Linux was already free.

Therefore I see it is not a pay for the update. What remains as a solution is to install Ubuntu 8.10. With Gnome as a desktop, I can arrange just yet, but the Gnome counterparts for file, music management and text, image, unfortunately, have not the same functions as those on the KDE. When, then do not install the Parallels Tools were, had to be a radical solution.

So Parallels out and Virtualbox pure. And what can I say. It rocks.

Conclusion: Sometimes you have to pull the financial handbrake. In this case also spared the nerves.
