-====== Setting it up ======
-A good page about setup of the raspberry, despite it talks about setting a raspberry for running java, it worths reading:
-  * http://www.oracle.com/technetwork/articles/java/raspberrypi-1704896.html
-How to send a whatsapp from a raspberry pi:
-http://rsppi.blogspot.com.es/2012/10/uso-de-whatsapp-para-el-envio-de.html
-Emuladores de consolas:

-===== Saving the image =====
-<code>
-unzip FILE-OF-IMAGE.zip
-dd bs=4M if=FILE-OF-IMAGE.img of=/dev...
-</code>
-Usually, ''/dev...'' corresponds --in Linux-- with ''/dev/mmcblk0'' or ''/dev/sdd'', depending on the configuration of your computer.
-===== Setting an static IP =====
-My plan is to use this Raspberry as a backup server (yes, I know that there is no much space in it, but the place I want to backup hasn't many space either).
-To configure an static IP, edit the file ''/etc/networking/interfaces'' and set the following values:
-<code>
-auto lo
-iface lo inet loopback
-iface eth0 inet static
-	address 192.168.1.4
-	network 192.168.1.0
-	netmask 255.255.255.0
-	gateway 192.168.1.1
-</code>
-It's a good idea to comment out the previous data, just in case.
-===== Setting up ssh =====
-Use the tool ''raspi-config''.
-===== Use the full space of the sd card =====
-Use the tool ''raspi-config''.
-===== Remap the keyboard =====
-Use the tool raspi-config
-===== Create another user, not the well known "pi" =====
-I prefer to create a regular user instead of the regular "pi" user. To do so:
-<code>
-# addgroup USERNAME
-# adduser --ingroup USERNAME --home /home/USERNAME  USERNAME
-</code>
-===== Add this user to the "sudo" group =====
-<code>
-# adduser USERNAME sudo
-</code>
-Test that you can log on as this user and run things as superuser. Then, you can delete the ''pi'' user.
-===== Delete the "pi" user =====
-Delete the pi user after testing the other username is working and can run things as superuser.
-<code>
-deluser --remove-home pi
-delgroup pi
-</code>
-===== Delete the sudoers information of "pi" user =====
-It is not necessarily, because it's already deleted, but imagine that someone manages to create again the pi user: it will have automatic sudo permissions for everything!!!
-To prevent that, issue the ''sudo visudo'' command and remove this line of the sudoers file:
-<code>
-pi ALL=(ALL) NOPASSWD: ALL
-</code>
-===== Think about backup =====
-Yes: Backup.
-This is the second time I run through this guide, because I've lost my card. Yes, memory cards broke. I suppose that too many writings can exhaust the capacity, and mine after some months running, broke. So it isn't a bad idea to think if you really need to back up some files.
-===== Make an upgrade of your distribution =====
-Do an update of the packages of your distribution.
-<code>
-# sudo apt-get update
-# sudo apt-get dist-upgrade
-</code>
-===== Remove the graphical desktop =====
-In my case, I rather prefer to remove the graphical desktop, because I am not going to use it, and this will make more room in the card.
-<code>
-apt-get remove --auto-remove --purge libx11-.*
-</code>
-According to:
-http://raspberrypi.stackexchange.com/questions/4745/how-to-uninstall-x-server-and-desktop-manager-when-running-as-headless-server
-Or, in case you want to use the graphical desktop, you can access remotely with this guide:
-http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-remote-desktop-raspberry-pi/
-===== Change the umask =====
-Edit the file ''/etc/login.defs'' in order to change the default umask.
-===== Install a mail program =====
-<code>
-# apt-get install bsd-mailx
-</code>
-===== Configure mail server =====
-I've removed exim and installed postfix because I know it better.
-<code>
-apt-get install postfix
-</code>
-And I make the necessary configurations to send and receive email from the raspberry. I've selected to use SMTP relaying of the emails because of the dynamic IP: it appeared in the Spamhaus' list and it was nearly impossible to send emails from there.
-For instructions to configure the relaying:

-http://ubuntu-tutorials.com/2008/11/11/relaying-postfix-smtp-via-smtpgmailcom/
-===== Set Timezone =====
-Don't forget to set the timezone.
-If ''raspi-config'' doesn't work, try this:
-<code>
-dpkg-reconfigure tzdata
-</code>
