Nessun difetto dunque. Invece sì. Le case produttrici di hardware non aspettano certo debian. E a dirla tutta nemmeno i fans di debian vogliono aspettare. Vogliono che la loro cara distro funzioni perfettamente su qualsiasi macchina. Come giungere a un compromesso?

No cook, no life. E' il blog di una persona che sta dedicando il suo tempo libero a Debian. Cioè...lo sta rendendo un po più appetibile per le moderne macchine che non vedono l'ora di modificare la versione del loro ich (per esempio).

Se abbiamo un processore multicore o più processori, per compilare più velocemente sfruttando il parallelismo, possiamo dare make con l'opzione -jn dove n sta per il numero di processori più 1. Oppure per fare in modo che ad ogni compilazione questo sia impostato di default basta impostare la variabile d'ambiente CONCURRENCY_LEVEL. Ma perché numero_processori+1? Tindal mi ha dato la risposta che copio ed incollo qui

il concurrency level va impostato ad un numero maggiore rispetto al numero di processori (o core), se vuoi risparmiare più tempo possibile parallelizzando i processi, per assicurare che ci sia sempre un processo avviabile quando c'è un po' di tempo di calcolo disponibile

ogni processo ha dei periodi in cui non riesce ad usare al massimo il processore: se hai 2 processori e 2 processi avrai qualche tempo morto per entrambi i processi, e il fatto di averne almeno un altro in esecuzione ti permette di usare anche questi tempi morti

bada che di solito parliamo di poco (penso che nella compilazione di un kernel puoi guadagnare al max 10-20 secondi, a occhio), ma dipende dai processi: più ci sono tempi morti più guadagni aumentando il numero di processi concorrenti

ah, ovviamente non riuscirai a fare molto altro con il pc mentre lo tieni così occupato

Ora daremo l'esempio più classico per i desktop moderni: due core (naturalmente vale sia per AMD che INTEL o altro...)

Per archlinux (o simili)

sudo nano /etc/profile

e aggiungiamo la riga

export CONCURRENCY_LEVEL = 3

poi

source /etc/profile

Prova che funzioni

echo $CONCURRENCY_LEVEL

Per debian (o simili)

sudo nano /etc/environment

e aggiungiamo la riga

export CONCURRENCY_LEVEL = 3

poi

source /etc/environment

Prova che funzioni

echo $CONCURRENCY_LEVEL

No obstante antes de reiniciar esta mañana, antes de quedarme sin Internet (gracias, muchas gracias ONO), abrí un Terminal, escribí el comando uname -a && uptime, le di al intro y esto es lo que salió:

Linux emac 2.6.24-1-powerpc #1 Sat May 10 11:39:20 UTC 2008 ppc GNU/Linux

08:33:05 up 34 days, 17:41,  2 users,  load average: 0.60, 0.81, 0.48

Con el nuevo nucleo,

Linux emac 2.6.25-2-powerpc #1 Fri Jun 27 04:51:57 UTC 2008 ppc GNU/Linux

parece q todo va a la perfección, y espero que el record de 35 días quede muy atrás.

¿Alguien da más?

To add enriched nuclear fuel to the fire, I couldn't work on my laptop. Why? Because of all the things I'd forgotten to do back from college, I forgot to configure my Debian for using the dial-up connection I have at home. And since I didn't have a pen drive to transfer content between my PC and my laptop, I was pretty much stuck. And if you didn't know, trying to work/hack on Windows is as good as trying to dance without feet. When the Google Code Jam happened yesterday, I couldn't submit my code because of this. I'd successfully solved one of the problems which was enough for me to qualify but darn.

On the bright side, I learnt python through that problem. I ain't that good a programmer and I'm still learning. As of now, I'm pretty much in love with python and this could be the one language I've been looking for since quite a while. An elegant combination of simplicity (near english like syntax) and power (very good built in datatypes and methods) is exactly what the doctor ordered in my case because I'm someone who wants to easily implement an algorithm without having to work out low level details. Haskell is the God of languages in this case which I'll come to shortly. And yes, I'm a lazy sloth.

During these three weeks, I tried my hand out in a lot of other things as well such as Perl, linux socket programming, linux driver coding, trivial kernel hacking and lastly, Haskell. Haskell is one thing that's impressed me a lot. Thanks Vivi for introducing me to it. Haskell is a purely functional programming language. To learn Haskell, you basically have to unlearn whatever programming you already know, and then learn it again from scratch. But learning Haskell makes you re-think and improve your programming methodology it seems. I didn't read too much on it because I couldn't download the Hugs compiler till I get back to college. No point learning if you can't try out code yourself, is there? Some ten/nine pointers I know would disagree :D . Anyways, Haskell works at a very high level compared to languages like C. Hence, you can do a quicksort in just one line! Yes, one line and thats it. Brilliant eh? Here's how it looks like...

qsort [] = []
qsort (x:xs) = qsort (filter (< x) xs) ++ [x] ++ qsort (filter (>= x) xs)

The first line means, "qsort on an empty list returns an empty list". The second line is read as follows, "qsort is a function operated on a list where the first element is x and the rest is tagged xs, such that the element x lies between two elements such that the ones on the right are greater than or equal to it and the ones on the left are less than or equal to it". ++ is the concatenation symbol. And yes, Haskell thrives on recursions.

I can't wait to get back to college and get into the hustle and bustle of life all over again. I'm also looking forward to attending the induction training programme for the Sun Campus Ambassadors in Bangalore between the 27th and 29th of this month. My CA work officially starts from the 1st of August. Anyways, I've laid down a set of goals for myself for the coming semester which according to Suvha, might lead to me ending up in an asylum. Maybe, I am overloading myself again. Maybe I'm not. Whatever the case, I guess I'm all for it now. I think I'm rejuvenated and wiser (laugh you morons...laugh) after a couple of lessons life thought me in the past few months. Let's see how things change now...

Cheers!

A veces, por pereza nomás, no nos gusta andar seleccionando la carpeta en que queremos guardar los archivos que descargamos y dejamos que Firefox tire todo en el escritorio. El escritorio es un lugar de trabajo cómodo. Todo está a mano y esa es su función. Pero llega un momento en que se llena.

Una solución interesante sería disponer de un lanzador (un simple ícono) sobre el cual arrastrar los archivos y que, según su tipo, se dirijan automáticamente a la carpeta que corresponde cada uno (Imágenes, Música, Documentos, etc.).

Esa es la idea de este simple script para bash. Las comillas dobles alrededor de $1 nos aseguran que no habrá problemas con los archivos con espacios en su nombre y los square brackets se usan para tener en cuenta mayúsculas y minúsculas.

#!/bin/bash
while [ $# -ge 1 ];
do
case "$1" in
*.[mM][pP]3)
mv "$1" ~/Musica
;;
*.[jJ][pP][gG] | *.[gG][iI][fF])
mv "$1" ~/Imagenes
;;
*.doc | *.[tT][xX][tT])
mv "$1" ~/Documentos
;;
*)
exit 0
;;
esac
shift
done

Creamos un archivo cuyo contenido sea el de arriba y lo grabamos en una carpeta donde tengamos nuestros scripts. Por ejemplo, podríamos llamar al script magic.sh y guardarlo en la carpeta /scripts, asegurándonos que todos los usuarios tengan permiso de paso sobre el directorio y ejecución del script. Para ello, una vez creado el archivo (si lo hicimos como root):

chmod -R a+x /scripts

Ahora que tenemos el script, debemos crear un lanzador en el escritorio. Botón derecho > Crear un lanzador. Le ponemos un nombre, un comentario y en comando escribimos la ruta completa al script; en este caso /scripts/magic.sh. Le ponemos un ícono lindo y listo.

Cuando tengamos un archivo con extensión jpg en el escritorio y lo arrastremos hasta nuestra "carpeta mágica", irá a parar automáticamente al directorio imágenes. Se pueden agregar tipos de archivos y carpetas extras. Es necesario que las carpetas destino estén creadas de antemano, claro.

1. Video Editing: Video editing is a major hobby of mine and it just happens to be the thing which Linux fails the hardest at. There is literally not a single useful piece of video editing software available to Linux. On Windows my primary mode of video production is Sony Vegas, but I have also done work in Adobe Premier, Ulead Video Studio, Windows Movie Maker and Pinnacle. Some of these are better than others (Vegas>Premier>Ulead>Pinnacle>WMM). When it comes to Linux video apps they are all equally bad (Kino=LiVES=Kdenlive=Cinerella=complete and utter shit). Some will argue that Cinerella is significantly better than the rest and to be honest this is true, however it is still so bad that it is equally incapable of producing a finished product and that is where it really counts. The programs are all missing their own extremely important aspects so the only way to really get even simple editing done is to have multiple editors open at the same time so that you can pass the project back and forth.

2. Audio Editing: Another of my hobbies is music production which again Linux is miserable at. Not quite as miserable as video editing but almost. Lately I have been using FL Studio because I prefer its interface, but should I ever change my mind, I know I can always switch to wonderful alternatives like Cubase, Reason and Sony Acid. Linux offers a program called Linux Multi-Media Studio which is clearly an FL Studio rip-off but it isn't pulled off quite as well. Again, the fact that it is free is nice, but it just doesn't stand up on its own as anything but an amateur level piece of software.

3. Image Editing: There is an image editing software god and its name is photoshop (peace be upon it). As with all of the previous softwares discussed, Photoshop can't be loaded onto linux without some major hiccups, meaning the user has to settle for a whole host of unsuitable alternatives. In this instance Linux offers GIMP which I have to admit, I like. It is a very good piece of software. Admittedly I don't like the interface but I assume with more practice I could get used to it. Still, it is far from being an alternative to Photoshop. It is simply a more powerful piece of equipment.

Aside from these 3 major areas I had some significant problems or distastes for some specific Linux equivalents. These programs included Maple 10/11, Mathematica, Matlab, and Texnic Center (I didn't really like any of the Linux Tex IDE's).

I really did like Ubuntu and wished that it would have fit my needs. It seems that Linux either succeeds spectacularly or fails miserably with everything it does. Meanwhile Windows enables me to do just about anything with very minor complications. For me, this makes Windows the better choice. Should many of these problems be sorted out or more and better software was developed to suit my needs, I would gladly make the switch back. Until then, Windows is my OS.

I had a chance to speak at the tail end of The Linux Link Tech Show to give a brief report about the two events to date. And if I sound a little exuberant, it's because I am. The project has gone better than my expectations, and there's a good argument that we won't have to do the "Microsoft-free for a week" because so many people have already converted to GNU/Linux that we can monitor their progress, find what works for them, what doesn't work for them, and they don't have to go back at the end of a week.

It's something to discuss, anyway.

Christian Einfeldt also started putting video together. If you want to see an example of Ken and me in action, you can go here for essentially a not-ready-for-prime-time version (only because it's raw footage, as the Digital Tipping Point provides, and it can be used by anyone -- yep, that's open-source video for you). Ken is on the right, I'm on the left (and that's by design). There will be more of this, and needless to say, we're going to be putting this together in a video form that will be shown to the general public. As for the events themselves, they will be up as soon as Christian can get an edited version up.

We've been discussing other things as well: It came up last night on the radio that tech help can come from anywhere with the proper equipment -- an IRC channel, a forum, a mailing list, etc. The guys at The Linux Link Tech Show have offered their help, as well as some time in a few weeks to have some of the Felton residents who have converted on the show.

Those items are all on at the top of the list, hopefully in place by the next event.

90 and sunny, becoming cooler as the evening approaches.

compiled it with :

cd /usr/src/modules/nvidia-kernel
make modules
make install

(nvidia module should now be there)

but we still need nvidia-glx (on my sourcelist i only got a wrong version, which made me search the nvidia page).
found a matching version (watch the output of the make command) and install only the glx part by following command:

yourNvidiaBinFile.run --no-kernel-module

okay. Server should be prepaired now the work again. But it would be "to easy".
To mass it up even more, there is a bug in dmsetup atm. which causes udev and initrds to fail. parts of this are wrong permission in some importent /dev/ devices.

to get the minimum back again you should set

chgrp users /dev/null
chgrp users /dev/random
chgrp users /dev/urandom

stressful and not like we know it from the debian system. but will be fixed for sure.

fixing the kernel the correct way:
/etc/udev/rules.d/65_dmsetup.rules
first lines all have GOTO="device_mapper_end".

which should look like this:

SUBSYSTEM!="block", GOTO="device_mapper_end"
KERNEL!="dm-*", GOTO="device_mapper_end"
ACTION!="add|change", GOTO="device_mapper_end"


than adjust you kernel to get sure everthings fine

update-initramfs -k all -u


Al parecer poderes de super vaca, es quien es mas poderoso, aptittude o apt, el asunto es q nosotros mismos podemos comprobarlo.

1. PhpMotion : Free(Gratis) tp kelemahannya adalah agak sulit menginstallnya.
2. Ostube : Free juga, tp yg versi community dengan segala keterbatasannya. tp mudah di install dan digunakan.
3. dan lain-lain. kebanyakan yang lain pada bayar dan harganya $100 keatas.

nah dengan pertimbangan diatas akhirnya gw memilih ostube. Untuk memudahkan membuatnya saya akan buat langkah per langkah :

1. Download ostube di situsnya, pertama harus register dulu baru bisa download.
2. Download juga dokumentasinya, seperti cara install nya dan lain-lain. ada 2 pilihan mo pk yg bahasa inggris ato jerman. pilih inggris aja lah, biar gampang.
3. Abis itu ikutin cara install nya.

Saya ada beberapa referensi buat cara installnya :

• http://lustan.wordpress.com/2008/02/13/streaming-server-with-ostube/
• install mencoder, ruby, flvtool2 dan mplayer di debian, karna gw coba ostube ini di debian http://linux.justinhartman.com/FFmpeg,_FFmpeg-PHP,_Lame,_Libogg,_Libvorbis,_FLVtool2,_Mplayer,_Mencoder,_AMR_Installation
• kalo ada error pas mo install libogg or libvorbis tambahin di ./configurenya --enable-share
• lainnya searching di google

kyknya segitu aja cara installnya, sory gak gw jelasin satu2, abisnya gw juga ikut tutorial org lain, jadi mendingan liat tutor org lain aja, sambil kalo ada error gw coba2 benerin,, hehehhehe,, Maaf yah kalo berantakan tulisannya.

Mudah-mudahan bermanfaat.

Dalam kasus ini saya pakai debian distro, Yang terbaru adalah Nmap 4.68 (saat tulsian ini dibuat) dan itu juga yang sekarang tidak saya pakai ;)). Pakai yang 4.11

donlot dulu Nmap dari www.insecure.org
#wget --alamat download-- a

atau lgsg install dari repository debian #apt-get install nmap <sarankan yang ini aja,stabil>

extract di direktori terserah (pastikan sudah terinstall bzip2) :

#tar -jxvf filename.tar.bz2

Install Nmap

#./configure
Tentukan target..lalu coba jalankan Nmap :
>>>> Untuk Stealth Scanning pakai koneksi TCP SYN:
#nmap -sS --IP address--

>>>> Untuk scan pakai koneksi TCP biasa :
#namp -sT --IP Address--

Untuk target terserah anda.:D. Ada bacaan lebih dari komunitas echo.or.id

Having a relax talk (and maybe some good food) is a better way to know people than the quick talks I'm used to from more formal meeting. And having the chance to show them a city or the country is of course something I can't do abroad (:

So, if you're in the area - let me know. I can't provide a place to crash, but can still help...

p.s.

The invetation is open to any free software related people... don't be shy.

Seguramente y en mas de una ocasión, ya sea buscando la forma de instalar algún programa o aplicación o solucionar algún problema que te surge, te ves en la necesidad de usar la terminal, ese desconocido que esta en todas partes y te has preguntado; ¿Y que fregados es la terminal? Ò simplemente no la usas por miedo o desconocimiento. Pues bien, esta “Mini-Guía”, tratara de mostrarte algunas cosas que te pueden ser de ayuda y así por fin perderle el miedo a la Terminal

¿Que es la Terminal?
La terminal es una forma de acceder al sistema sin utilizar la interfaz gráfica, es decir, todo lo realiza a partir de ordenes escritas, lo que quiere decir que tienes el poder de controlar las acciones y ver como se realiza cada una de ellas.

Entonces... ¿Que es lo que veo en la terminal?

Lo primero que vemos es el “prompt”, que es el indicador de la linea de comandos el cual esta esperando a que introduzcas una orden.
Este puede variar al final, usa el símbolo "$" si eres un usuario normal y “#” cuando accedes como superusuario (root/Administrador).

Nota: El carácter “~” que usualmente verás al iniciar un terminal indica que estás en el directorio /home/usuario. Es una especie de abreviatura.

Acceder a una Terminal

Para acceder a una terminal se puede hacer de dos formas, una es con una aplicación como el terminal de GNOME, xterm o konsole de KDE, que son emuladores de la terminal dentro de una interfaz visual. Otra forma es salirse del entorno gráfico y acceder a un entorno completamente en modo texto, para esto último debemos teclear Control+Alt+F1. Linux proporciona por defecto seis terminales de este tipo, de Control+Alt*F1 a Control+Alt+F6. Si queremos volver al modo gráfico lo hacemos con Control+Alt+F7.

Sobre los Comandos ù Ordenes

Cuando trabajamos en la terminal, le damos ordenes por medio de comandos, estos son en forma de texto, si eres un usuario regular esto no te agradara, pero con el tiempo veras que hay “algunas” cosas que indudablemente son mas rápidas y eficientes mediante una terminal.

Algunos trucos

Tal vez, quieras saber que comandos puedas usar en la terminal, si es así, estarás feliz al saber que pulsando dos veces la tecla “Tab” (Junto a la letra “q”) se te presentara un listado con las posibilidades, al igual si escribes, parte de un comando, se te mostraran los posibles comandos a usar.

En este caso, no escribí nada, así que me dará todos los comandos disponibles, enseguida escribí “apt” seguidamente pulse dos veces la tecla “Tab” y me dio los posibles resultados para “apt”.

Si deseas mas información acerca de comandos te recomiendo visitar la "Lista de Comandos" de la comunidad Debian en español

Mejorando el Aspecto de la Terminal

Sin duda, cuando algo se ve bien, mejora bastante la experiencia con la aplicación.
Le daremos este aspecto:

Nota: La imagen es el fondo de pantalla (la ventana es transparente)

Para esto aplicaremos los siguientes cambios.

En el menú ”Editar” seleccionamos ”Perfil Actual”

**Pestaña: General

>Nombramos nuestro perfil
>Desmarcamos la casilla ”Usar la tipografía de ancho fijo del sistema” y seleccionamos una que se acomode a nuestras necesidades (en este caso Monospace 8 )

**Pestaña: Titulo y Comando
>Titulo
>>Podemos asignarle un titulo cualquiera a la Terminal

>>Si seleccionamos ”No se muestra” en el ”Titulo establecido Dinamicamente”, solo se mostrara el Titulo que le hemos dado.

**Pestaña: Colores

>>Desmarcamos la casilla de ”Usar colores del tema del Sistema” y podremos seleccionar un esquema de colores acorde a nuestros gustos, en este caso ”Vede Sobre Negro”

**Pestaña: Efectos

>Aquí podemos seleccionar si:
>Poner una imagen de fondo
ó
>Hacer traslucido el fondo (En este caso seleccionamos este)

**Pestaña: Desplazamiento
>Aqui podremos desactivar la barra de desplazamiento o acomodarla donde nos convenga

Despite the numbers not being high on Tuesday night, the momentum continues and can be gauged in ways that may not be thought of as conventional. For example, one of the most astounding phenomena I've ever encountered is that people are coming in with their hardware -- and this happened on Tuesday as well -- and essentially saying "I've had enough of Windows -- give me Linux." These folks don't want to try it out first; they're so angry at Microsoft that they're looking for alternatives.

One fellow wanted to buy a Zareason box -- Zareason was on hand on Sunday, but they were not around on Tuesday. Christian was able to call Zareason and hand the man his phone, and hopefully he went home with a Zareason computer.

Today, Ken and I had a chance to finally sit down and talk about what worked on these first two days and what didn't. Meanwhile, interest has been raised on the project in a way that people are starting to say, "Hey, I can do this in my community," and suburban Portland, Ore., may be next on this continent to take up the Lindependence project.

Stay tuned. There's another meeting scheduled for a week from Saturday -- that would be July 26, and it coincides with a big celebration of the town buying back its waterworks from a multinational corporation (the dinner and dance is in the evening; the meeting/installfest is in the afternoon).

To rename a Debian system, it is not enough to change the /etc/hostname file, you probably need to change some references to the old name elsewhere. This article tries to pinpoint the files where it would be needed to change it. Be careful, the name may also be configured in specific applications, like in some databases.

System files, where changes are mandatory

• /etc/hostname
• /etc/hosts
• /etc/mailname
• Configuration files for the MTA used

Application files, depending on the program

It is not possible to list every possible application configuration file where the name may have been hardcoded. So the simplest way to detect them is to do the following:

# rgrep -i oldname /etc/*

where oldname is the previous hostname.

And of course, don't forget to change the name references on other machines of the network also, where it applies.

Some people used devfs under Woody, or under their previous Sarge install. When going kernel 2.6, it may be useful to revert or upgrade to udev instead. The problem is that their nomenclatura is different, so your system may be rendered unbootable. Let's see what to care about to switch from devfs to udev.

First, the bootloader will no longer need the devfs=mount parameter on the kernel command-line. So, wheter you use GRUB or LILO, remove or comment the reference to devfs=mount.

Second, check in your /etc/fstab that you have nothing in devfs-nomenclatura, like /dev/ide/host0/bus0/target0/lun0/part3, but everything in the standard nomenclatura like /dev/hda3.

Third, install the udev package, it will probably bring some dependencies too. That's ok.

Last, check the links in /etc/udev/rules.d/. There are probably two links to the upper directory: compat-full.rules and devfs.rules. Remove them and create a new link to udev.rules and to cd-aliases.rules like this:

# cd /etc/udev/rules.d/
# rm compat-full.rules devfs.rules
# ln -s ../udev.rules .
# ln -s ../cd-aliases.rules .

Now, reboot, and if you want, remove package devfsd.

Note: It may also be necessary to reconfigure some special packages which store device information in their configuration file, like XFree86.

Getty is known to be memory-hungry. Let's replace it with something lighter, which works in most cases: fgetty

On Debian Sarge and up, it is already packaged, so sudo apt-get install fgetty will do the trick. But this is not sufficent for it to be installed instead of getty.

You will have to edit /etc/inittab. Warning: this is a very dangerous file to edit, as it may render your system unbootable. You have been warned!

The following lines call getty

:

1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
...

Lets replace it with fgetty, which takes less arguments:

1:23:respawn:/sbin/fgetty tty1
2:23:respawn:/sbin/fgetty tty2
...

And do that for as many virtual consoles you would like to have. If you don't need many, comment the lines, but I advise you to keep at least 2.

Save the file and exit.

And then, restart init:

# killall -HUP init

You're done!

Starting from Debian Sarge, the Samba version which ship with Debian is 3.0.x. This is the first real version to support well being a PDC while using LDAP as backend.

Here is how to use Samba as PDC with LDAP backend for authentication on Debian.

Install the following packages, which are all part of Samba

• samba: The server itself
• samba-doc: The documentation (very complete)
• smbclient: FTP-like client for SMB/CiFS
• swat: Samba Web Administration Tool (web interface to configure Samba and access the full documentation through a browser, if installed)

Aside, we will install LDAP

• slapd: the server itself

Some companies provide useful tools to help in the setting up of a Samba server with LDAP as PDC:

• smbldap-tools: IDEALX tools for Samba use to ease installation and migration when using together with LDAP

Configure the Name Service Switch to use LDAP

Install package libnss-ldap and configure it according to the LDAP configuration [1].

Edit /etc/nsswitch.conf by adding a mention ldap to the end of the three following lines: passwd:, group:, shadow: and a mention wins to the end of the line hosts:.

Configure PAM to also use LDAP

Install package libpam-ldap and configure it according to the LDAP configuration.

Edit /etc/pam.d/common-account and add the following line before the existing second line:

account  sufficient     pam_ldap.so
account required        pam_unix.so

Edit /etc/pam.d/common-auth and add the following line before the existing second line:

auth    sufficient      pam_ldap.so
auth    required        pam_unix.so nullok_secure

Edit /etc/pam.d/common-password and add the following line before the existing second line:

password   sufficient pam_ldap.so
password   required   pam_unix.so nullok obscure min=4 max=8 md5

Set the LDAP password in Samba

Samba stores its passwords in /var/lib/samba/secrets.tdb, and also stores there the LDAP admin password to use to connect to OpenLDAP. To set/change the password:

smbpasswd -w MySecretPassword

where MySecretPassword is LDAP's admin password.

Add the Samba schema to OpenLDAP's list of schemas

An example that you can copy "as is" (well, you just need to unzip it first) is available in /usr/share/doc/samba-doc/examples/LDAP/samba.schema.gz in /etc/ldap/schemas and edit /etc/ldap/slapd.conf to use it.

Configure /etc/ldap/ldap.conf and /etc/ldap/slapd.conf.

Tools to manage it afterwards

LDAP Account Manager (LAM) (web-based frontend to Samba accounts for machines, users and groups in LDAP) or phpLDAPadmin (which is not specific for managing Samba, but can also manage addressbooks, UNIX authentication, …).

Create your machines in the Domain
