====== Setting it up ======



A good page about setup of the raspberry, despite it talks about setting a raspberry for running java, it worths reading:

===== 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>
# adduser --group --home /home/USERNAME  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:

===== 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>
