Calaos quick start guide

Raspberry pi quick start guide

What you will need

A computer with Linux, MacosX or Windows

A Raspberry pi, Model B

An SD Card, We recommend an 2GB class 4 SD card

Download the latest official calaos image for raspberrypi :http://calaos.fr/download/experimental/calaos-image-raspberrypi-2014-04-28.tar.xz

Creating the SD card with calaos os

Linux

Launch a terminal and go in the directory where you download the calaos os image.

$ cd ~/Downloads
$ tar xvf calaos-image-raspberrypi-2014-04-28.tar.xz

Insert the sdcard into the sdcard reader of your PC. You need to know what's the device created by linux when the card is inserted. The device name is something like /dev/sdX or /dev/mmcblkX. To know the exact name use the following command :

$ dmesg | tail

You should get something like that :

[191385.790344] mmc0: new high speed SDHC card at address 1234
[191385.790574] mmcblk0: mmc0:1234 SA04G 3.67 GiB
[191385.791564] mmcblk0: p1 p2

In that case the device is /dev/mmvblk0

We need to ensure that this device is not mounted on your system

$ sudo unmount /dev/mmvblk0p1
$ sudo unmount /dev/mmvblk0p2
...

or in case your device is detected as /dev/sdX

$ sudo unmount /dev/sdd1
$ sudo unmount /dev/sdd2
...

You can verify that the devices are not mounted by using the mount command

$ mount

No sdcard must appears in the resulting list.

Let's now copy the calaos os on the sdcard

sudo dd if=calaos-image-raspberrypi-2014-04-28.sdimg of=/dev/mmcblk0

Once the operation is terminated, you can remove the sdcard, and insert it in the Raspberry pi.

Macos

You can use ApplePi-Baker. It's a free utility tha allows you to write an image to the sdcard. It can be download here : http://www.tweaking4all.com/downloads/raspberrypi/ApplePi-Baker.zip

Windows

You can use Win32DiskImager. You can download it here : http://sourceforge.net/projects/win32diskimager/

Connecting to the Rpi

When you boot the raspberrypi, the network is configure to use dhcp, so you need to know what's the address the dhcp server give you. Or if you are using MacOS or Linux, you may try to connect to it with :

ssh root@rasberrypi

If you already know the IP address, just connect directly :

ssh root@ip_address

The default password is empty. If you have trouble to find the ip adress, look here : http://www.raspberrypi.org/documentation/troubleshooting/hardware/networking/ip-address.md it may give you some hints.

NOTE : on Linux and MacosX you can use the Terminal to use ssh. On windows you need a program like putty to connect to the raspberrypi : http://www.putty.org/

Calaos Server configuration

The first thing to do is to start calaos_server to let him create a defaut set of config files in /etc/calaos :

systemctl start calaos-server

Then you can set the basic parameters of your calaos installation : username and password.

$ calaos_config set cn_user nico
$ calaos_config set cn_pass calaos_rox

These user and password are those that you will use to connect from Calaos Web, Calaos Home or Calaos Installer. By default when you boot the raspberrypi with a Calaos OS image, calaos-server is not started automatically. If you want it activated every time you start the card, enable it at startup with the following command :

systemctl enable calaos-server

To see if everything is working fine with calaos server, you can try to connect to the server via Calaos Web. Start your favorite web browser and connect to http://raspberrypi or http://ip_address You should be able to login, but nothing is displayed in the interface. It's completely normal as we don't have configured the whole installation yet. What we need now is to create the configuration of our house, and Calaos Installer will be used for that.

House configuration with Calaos Installer

Calaos Installer is an application for Linux, Macos X and Windows. You can download it here : TBD
