This post documents how I have set up my Raspberry Pi (model B+) for double duty as a VSCP daemon server and a pimped doorbell. This page is mostly for my own reference.

Static IP

Find the DHCP address assigned to the Raspi. Log onto the Raspi through SSH and note the current IP settings:

sudo ifconfig

Then edit the /etc/network/interfaces file.

/etc/network/interfaces

Change interface eth0 to:

#iface eth0 inet manual
iface eth0 inet static
address 192.168.1.8
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Reboot:

sudo reboot

As per ()this tutorial)[http://thepihut.com/blogs/raspberry-pi-tutorials/16683276-how-to-setup-a-static-ip-address-on-your-raspberry-pi]

Change hostname

sudo nano /etc/hosts

Change default hostname raspberrypi to something more descriptive:

127.0.1.1       raspi-doorbell

Edit hostname file:

sudo nano /etc/hostname

Change hostname:

raspi-satNOGS

Commit changes:

sudo /etc/init.d/hostname.sh

As per this tutorial

Update & upgrade

sudo apt-get update
sudo apt-get upgrade

Set time zone

Run the following command:

sudo tzselect 
sudo raspi-config

Automount NAS file share

Created new mount destination:

mkdir /media/netwerkdrive

Added this line to /etc/fstab: //192.168.1.6/netwerkdrive /media/netwerkdrive cifs guest,uid=1000,iocharset=utf8 0 0

Mount with:

mount /media/netwerkdrive

Will automatically mount upon startup.

Share a local folder on the network

Install Samba

apt-get install samba samba-common-bin

Configure Samba

Remove password for nobody user

smbpasswd -an nobody

Added the following to /etc/samba/smb.conf:

security = user
guest account = nobody
map to guest = bad password

[fileshare]
comment=fileshare on Raspi    
browseable=yes
path=/fileshare
public=yes
writable=yes
guest ok=yes

As per this tutorial

Start Samba

service samba start

TightVNC

Installed as per this tutorial.

Start at boot as per this tutorial

Fixed logon problem as per this tutorial

sudo mv /home/john/.Xauthority /home/john/.Xauthority-backup

Start Doorbell script at startup

There are loads of ways of running a command at start-up in Linux. Here we’ll create an initialisation script in /etc/init.d and register it using update-rc.d. This way the application is started and stopped automatically when the system boots / shuts down.

Create script in /etc/init.d

sudo nano /etc/init.d/startDoorbell

The following is an example based on starting up my doorbell script, but change the name of the script and the command to start and stop it, and it would work for any command.

#!/bin/sh
### BEGIN INIT INFO
# Provides:          startdoorbell
# Required-Start:    $local_fs  
# Required-Stop:     $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start/stop startdoorbell.sh
### END INIT INFO

### Customize this entry
# Set the USER variable to the name of the user to start tightvncserver under
export USER='pi'
### End customization required

eval cd ~$USER

case "$1" in
	start)
#   	 su $USER -c 'sh /usr/bin/startdoorbell.sh'
		sh /usr/bin/startdoorbell.sh
		echo "Starting startdoorbell.sh for $USER "
		;;
	stop)
		pkill startdoorbell
		echo "startdoorbell stopped"
		;;
	*)
		echo "Usage: /etc/init.d/startdoorbell {start|stop}"
		exit 1
		;;
esac
exit 0

Warning - its important you test your script first and make sure it doesn’t need a user to provide a response, press “y” or similar, because you may find it hangs the Raspberry Pi on boot waiting for a user (who’s not there) to do something!

Make script executable:

sudo chmod 755 /etc/init.d/startdoorbell.sh

Test starting the program:

sudo /etc/init.d/startdoorbell start

Test stopping the program:

sudo /etc/init.d/startdoorbell stop

To register your script to be run at start-up and shutdown, run the following command:

sudo update-rc.d startdoorbell defaults

Note - The header at the start is to make the script LSB compliant and provides details about the start up script and you should only need to change the name. If you want to know more about creating LSB scripts for managing services, see http://wiki.debian.org/LSBInitScripts

If you ever want to remove the script from start-up, run the following command:

sudo update-rc.d -f  startdoorbell remove
