h1. Milano

Per Milano abbiamo bisogno di uno SCHEDINO che mandi dei video e degli slideshow in modo automatico, che sia affidabile, si possa riavviare, sia accessibile da remoto, stia in rete e faccia anche il caffe'.

Un primo sopralluogo e' stato fatto a Milano, ed i successivi lavori dal 4 all'8 Maggio 2015, in casa Roveda etc. :)

Questo schedino e' il RASP PI, 4 core, nuovo. Puo' benissimo essere considerato il prototipo di WeBox, ottima base di partenza.

h2. Istruzioni per riproduzione video / slideshow

*I video .mp4 vanno uploadati SOLAMENTE nella directory /home/pi/video*
*Le foto DEVONO essere uploadate SOLAMENTE nella directory /home/pi/foto*

Uno script rigenerera' la lista dei video da mandare in play, leggendo la dir. /home/pi/video e creando la lista da capo ogni tot minuti / ad ogni riavvio.

Questo vuol dire che ogni video uploadato sara' aggiunto in lista agli altri.

*Se volete mandare in play UN SOLO VIDEO, allora dovete loggarvi nello schedino rasp relativo, entrare nella dir. /home/pi/video e cancellare a manina i video indesiderati.*

h2. TODO URGENTE ASBESTO, APPUNTI

*ffprobe non esiste perche' DEBIAN MERDA, SI CHIAMA avprobe. quindi dur.sh non funziona. quindi listamp4.sh non genera le liste. PORCO DIO. cambiando ffprobe in avprobe dentro dur.sh sistema tutto. da fare con ricettina di ansible per farlo su tutti i nodi.* __


h2. CARATTERISTICHE REALI (gia' realizzate)

# Sistema basato su distro Raspbian (Debian ARM per Raspberry PI) aggiornata all'ultima release.
# Tutto standard, niente repository strani o esoterici.
# Immagine disco pronto con tutto quel che serve <3GB
# Partizione di Boot in READ-ONLY ad evitare smerdamenti del FS in caso di spegnimento brutale. Pro: non si smerda il FS ed e' molto stabile. Contro: Crontab non funziona, "at" credo non funzioni nemmeno (serve ulteriore verifica)
# Rete configurata in modo SEMPLICE tramite /etc/network/interface. Non serve NIENTE ALTRO.
# Script di autoavvio bash molto semplice. Serie di script dentro /home/pi/shells/
# Rete configurabile via ETH0 o WLAN0, cavo o wifi.
# hostname configurato automaticamente come "raspamiXX" con XX = ultima parte dell'IP della scheda wlan0 (si puo fare anche con eth0)
# Schedine USB wifi gia' configurate per funzionare bene con il loro firmware gia' installato e pronto.
# Implementa un wifi scanner per capire cosa il raspberry sente attorno a se.
# Screensaver e screen blanking disabilitati
# Sistema automatico di controllo rete: se si sente "disconnesso" riavvia la rete (e non il raspberry!) ricollegandosi, facendo il controllo ogni 2 minuti.
# Accesso tramite VPN, automatico e con autocontrollo: se manca rete, quando torna, la VPN torna su senza problemi. Con mosh la connessione non cade *MAI*!
# Accesso grafico tramite VNC stile teamviewer sempre tramite VPN ;)
# Chromium installato per navigare / configurare apparati via vnc/vpn
# ansible installato e pronto all'uso
# ricette ansible per modificare automaticamente tutti i rasp in rete
# pennini wifi senza il maledetto power saving: connessione finalmente stabile! (HACK)

h2. CARATTERISTICHE DESIDERATE / IN LAVORAZIONE O STUDIO

-* underclock sistema? non necessario al momento, non serve a un cazzo-
* VPN gestita interamente dai nostri server (zaverio.com) (voyanet cmq e' affidabile ed io sono root su una macchina apposita, quindi non so quanto questo sia necessario)
* Mplayer accelerato per rasp pi: fare check su quei 2 link che sono spariti
* Test su programma in PYTHON per controllare OMXPlayer, che PARE usi addirittura OSC per fare solo POCHE cose.
* Check telecamerina del raspberry e test di streaming audio/video

= Raspberry setup by Asbesto =

A solid setup for a raspberry sending videos / slideshow, can be rebooted / accessed by remote vpn, and make coffee.

This is for Rasp PI 3, quad core.

== Console blanking disable ==

Consoleblank is a kernel parameter. In order to be permanently set, it needs to be defined on the kernel command line.

{{{
sudo nano /boot/cmdline.txt
}}}

Add '''consoleblank=0''' to turn screen blanking off completely, or edit it to set the number of seconds of inactivity before the console will blank. Note the kernel command line must be a single line of text.

== Howto about video / slideshow ==

 * .mp4 files goes ONLY INTO /home/pi/video
 * Pictures goes ONLY INTO /home/pi/foto

A script generate the video list to go on play, reading that dir /home/pi/video and creating a new list every X minutes or at every reboot.

so every added video will be added to the playlist.

To play only a particular video you must remove all others.

== TODO ASBESTO, notepad ==

* ffprobe doesn't exist because DEBIAN SHIT, it was named avprobe. so dur.sh didn't worked. so listamp4.sh didn't generate any list. PORCODIO!
changing ffprobe in avprobe inside dur.sh fixed everything.

== Features ==

 * Based on Raspbian
 * All standard repo's
 * Disk image ready with everything, <3GB
 * READ ONLY boot partition to avoid shit on the FS in case of brutal poweroff. But so, crontab doesn't work, "at" also maybe not. TO BE CHECKED
 * Simple network config in /etc/network/interface. Nothing else needed.
 * Very simple startup bash script that launch everything. Other scripts in /home/pi/shells/
 * Network config via ETH0 o WLAN0, cable o wifi.
 * Automatic hostname as "raspamiXX" where XX = last number of the wlan0 IP address (same can be done with eth0)
 * USB wifi dongles already configured with their own firmware etc.
 * Implement a wifi scanner
 * Screensaver & screen blanking disabled
 * Automatic network check: if disconnected, reboot network subsystem, checking every 2 minutes.
 * VPN access / mosh / screen
 * VNC access under VPN :)
 * Chromium installed
 * ansible and recipes to mod every rasp in the network
 * USB wifi dongles configured without the FUCKING POWERSAVING MODE.

== IDEAS ==

 * underclock sistema? non necessario al momento, non serve a un cazzo-
 * VPN gestita interamente dai nostri server (zaverio.com) (voyanet cmq e' affidabile ed io sono root su una macchina apposita, quindi non so quanto
questo sia necessario)
 * Mplayer accelerato per rasp pi: fare check su quei 2 link che sono spariti
 * Test su programma in PYTHON per controllare OMXPlayer, che PARE usi addirittura OSC per fare solo POCHE cose.
 * Check telecamerina del raspberry e test di streaming audio/video

h2. ACCESSO allo schedino

Si entra con utenza pi, pw vivabasaglia. la pw root e' la nostra solita.

Il sistema parte, e lancia /home/pi/shells/start.sh - da li parte tutto quel che serve, impostazioni e programmi.

h2. RETE sul posto

Il router e' via wireless su 10.0.0.1 ed il suo dhcp assegna indirizzi sulla classe 10.0.0.1
Per accedere al router: admin/nostrapwsolita

telecom merda ha indirizzi 192.168.1.1 router, il resto BOH.
PARE che su eth0 ci sia un dhcp che da 192.168.1.200

Noi assegnamo ai raspi 10.0.1.50 in poi, con eth0 fissa a 172.16.0.50

h2. Check automatico per rete su o giu'

Questo script controlla ogni due minuti se la rete e' su, altrimenti restarta il networking.
Viene lanciato in background con "sleep 120" perche' crontab non puo' funzionare al momento perche' il fs boot e' in Read Only (vedi sotto x dettagli).

<pre>
== ACCESSING THE SHIT ==

USER pi, PW vivabasaglia. Root pw is "ciaras".

System boots and launch /home/pi/shells/start.sh - from there, everything starts.

== Automagic check for network up/down ==

Every 2 minutes this piece of shit check for network and eventually put it on again.

It's in background with "sleep 120" because here NO crontab due to the RO fs.

BELLO sarebbe... SE FUNZIONASSE.

h2. USCITA HDMI sempre attiva

Va settata, altrimenti se il tv si accende dopo il rasp, automaticamente quest'ultimo switcha sul connettore video out.
== Sistema in READ ONLY? ==

NICE TO DO.

Only /boot for now is read only, /tmp is in tmpfs ramdisk, with some /var links. So crontab is volatile.

MAYBE we can put crontab symlinks on /boot so we can have a fixed crontab to be modified into /boot.

Raspberry setup by Asbesto

A solid setup for a raspberry sending videos / slideshow, can be rebooted / accessed by remote vpn, and make coffee.

This is for Rasp PI 3, quad core.

Console blanking disable

Consoleblank is a kernel parameter. In order to be permanently set, it needs to be defined on the kernel command line.

sudo nano /boot/cmdline.txt

Add consoleblank=0 to turn screen blanking off completely, or edit it to set the number of seconds of inactivity before the console will blank. Note the kernel command line must be a single line of text.

Howto about video / slideshow

  • .mp4 files goes ONLY INTO /home/pi/video
  • Pictures goes ONLY INTO /home/pi/foto

A script generate the video list to go on play, reading that dir /home/pi/video and creating a new list every X minutes or at every reboot.

so every added video will be added to the playlist.

To play only a particular video you must remove all others.

TODO ASBESTO, notepad

* ffprobe doesn't exist because DEBIAN SHIT, it was named avprobe. so dur.sh didn't worked. so listamp4.sh didn't generate any list. PORCODIO! changing ffprobe in avprobe inside dur.sh fixed everything.

Features

  • Based on Raspbian
  • All standard repo's
  • Disk image ready with everything, <3GB

  • READ ONLY boot partition to avoid shit on the FS in case of brutal poweroff. But so, crontab doesn't work, "at" also maybe not. TO BE CHECKED
  • Simple network config in /etc/network/interface. Nothing else needed.
  • Very simple startup bash script that launch everything. Other scripts in /home/pi/shells/
  • Network config via ETH0 o WLAN0, cable o wifi.
  • Automatic hostname as "raspamiXX" where XX = last number of the wlan0 IP address (same can be done with eth0)
  • USB wifi dongles already configured with their own firmware etc.
  • Implement a wifi scanner
  • Screensaver & screen blanking disabled

  • Automatic network check: if disconnected, reboot network subsystem, checking every 2 minutes.
  • VPN access / mosh / screen
  • VNC access under VPN :)

  • Chromium installed
  • ansible and recipes to mod every rasp in the network
  • USB wifi dongles configured without the FUCKING POWERSAVING MODE.

IDEAS

  • underclock sistema? non necessario al momento, non serve a un cazzo-
  • VPN gestita interamente dai nostri server (zaverio.com) (voyanet cmq e' affidabile ed io sono root su una macchina apposita, quindi non so quanto

questo sia necessario)

  • Mplayer accelerato per rasp pi: fare check su quei 2 link che sono spariti
  • Test su programma in PYTHON per controllare OMXPlayer, che PARE usi addirittura OSC per fare solo POCHE cose.
  • Check telecamerina del raspberry e test di streaming audio/video

ACCESSING THE SHIT

USER pi, PW vivabasaglia. Root pw is "ciaras".

System boots and launch /home/pi/shells/start.sh - from there, everything starts.

Automagic check for network up/down

Every 2 minutes this piece of shit check for network and eventually put it on again.

It's in background with "sleep 120" because here NO crontab due to the RO fs.

while (true); do
 x=`ping -c2 google.com 2>&1 | grep unknown`
 if [ ! "$x" = "" ]; then
    echo `date` >> /home/pi/netcheck.log
    echo "Line is down. restarting..." >> /home/pi/netcheck.log
    service networking restart
    echo "done" >>/home/pi/netcheck.log
 fi
sleep 120
done

This script is named netcheck, in /usr/local/sbinand starts from /etc/rc.local:

# into rc.local
nohup /usr/local/sbin/netcheck &

Hostname with last IP number in it

The script is "ultimo" in /usr/local/sbin/ultimo:

#
# in base all'ultimo numero dell'IP del wifi, crea /etc/hostname.
#
IP=`ifconfig wlan0 | grep addr: | sed 's/.*inet *//; s/ .*//'`
cn=$(awk -F. '$0=$4' <<< $IP)
echo "raspami"$cn > /etc/hostname

and start from /etc/rc.local:

# change /etc/hostname adding last IP number from wifi
/usr/local/sbin/ultimo &

VPN

We use Voyager's vpn :)

VPN install on rasp

sudo apt-get install openvpn

next, copy the .conf file already prepared with all certs etc. (ex. for rasp number 50 use 50.conf)

after that

openvpn ./50.conf

or copy 50.conf into /etc/openvpn/client.conf

and launch from /etc/rc.local

service openvpn start

VPN on our computers

Same shit but using our personal certs.

VNC server/client install and usage

A teamviewer-like piece of shit, very handy!

VNC installation on raspberry

Look https://www.raspberrypi.org/documentation/remote-access/vnc/

sudo apt-get install tightvncserver

and launch tightvncserver to configure it, here you give a password that you will need to access.

in ~/shells/start.sh I added

vncserver :1 &

VNC installation on our computers

sudo apt-get install xtightvncviewer

so just launch

vncviewer 172.16.66.9:1

put the pw and desktop appears. END OF SHIT

LAUNCH with:

ansible-playbook --ask-pass ./pi.yml

For a single ip, ex. il 10.0.1.77, use

ansible-playbook --ask-pass -l 10.0.1.77 ./pi.yml

IP must be configured into /etc/ansible/hosts, as follow:

# This is the default ansible 'hosts' file.
#
# It should live in /etc/ansible/hosts
#
#   - Comments begin with the '#' character
#   - Blank lines are ignored
#   - Groups of hosts are delimited by [header] elements
#   - You can enter hostnames or ip addresses
#   - A hostname/ip can be a member of multiple groups

# Ex 1: Ungrouped hosts, specify before any group headers.

BLACK SCREEN AT BOOT AVOIDING messages and logos

Edit /boot/cmdline.txt

boot log:

instead of tty1

NO: better have logs to understand if it's booting or not. I left only loglevel=3 & logo.nologo

Fuck the logo: add at the end

lxde startup and HOW THEY'RE SON OF BITCHES

THOSE RASPBIAN BASTARDS CHANGED LXDE in LXDE-pi INTO ~/.config/lxsession so autostart didn't worked.

It's from there that I launch ~/shells/start.sh ;)

WIFI dongle

https://github.com/lwfinger/rtl8188eu

From here you download the zip file, inside is the fucking firmware.

The .bin goes in /lib/firmware/rtlwifi

Next you need the correct driver according to the kernel: https://www.raspberrypi.org/forums/viewtopic.php?p=462982

For our kernel, Linux raspami1 3.18.7-v7+ #755 SMP PREEMPT Thu Feb 12 17:20:48 GMT 2015 armv7l GNU/Linux

the correct firmware is

3.18.7-v7+ #755, #756 - 8188eu-v7-20150212.tar.gz

So, from root:

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-v7-20150212.tar.gz
tar xzf 8188eu-v7-20150212.tar.gz
./install.sh

and reboot!

Old notes

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20140307.tar.gz //make sure you use the correct dropbox url for your Raspberry version
tar -zxvf 8188eu-20140307.tar.gz
sudo cp rtl8188eufw.bin /lib/firmware/rtlwifi //not needed anymore if your operating system is above 3.10.33+
sudo install -p -m 644 8188eu.ko /lib/modules/3.10.33+/kernel/drivers/net/wireless
sudo insmod /lib/modules/3.10.33+/kernel/drivers/net/wireless/8188eu.ko
sudo depmod -a
sudo reboot

WIFI Scanner

Get rid of LXDE background, putting a black background

Remove from background, and put it black. You do it from X. After that, from desktop options, remove trash icon, so now you have to just kill the panel.

Killing the panel

Kill lxpanel. If you need it again, relaunch with lxpanel --profile LXDE-pi : launch directly ~/shells/panel.sh

BLANK SCREEN disabling

xset -dpms  
xset s noblank  
xset s off 

it's into ~/shells/start.sh

solve SLOW SSH

One workaround is to edit /etc/sshd_config on the sshd server machine, not your ssh client machine to set "UseDNS" to "no". (From the way you originally wrote your question, it sounded like you may have edited that file on your client, which wouldn't make a difference.)

Another solution would be to have your ISP (or whatever institution is responsible for your publicly-routable IP addresses) fix their reverse-DNS record for your IP address on their DNS name servers that are authoritative for the reverse-DNS records for that block of IP addresses. In other words, "make it so people can find your host name based on your IP address, and make sure the hostname they find maps back to your IP address". 7 mins · Unlike · 1

Set into ssh config: UseDNS no

LIGHT problem in raspberry PI 2

U16 is sensible to light. Cover it!.

http://www.pcpro.co.uk/components/1000375/why-a-camera-flash-will-reboot-your-raspberry-pi-2

Sistema in READ ONLY?

NICE TO DO.

Only /boot for now is read only, /tmp is in tmpfs ramdisk, with some /var links. So crontab is volatile.

MAYBE we can put crontab symlinks on /boot so we can have a fixed crontab to be modified into /boot.

HDMI port always ON

WE NEED THIS Because if we don't have hdmi active, the raspberry switches itself on the crappy video out connector.

Add these two lines to */boot/config.txt* and reboot Raspbmc:

hdmi_force_hotplug=1
hdmi_drive=2

SDCARD duplication

image is milano2.img

  • Insert sdcard into the pc
  • sudo dd if=milano2.img of=/dev/sdb bs=4096

  • sudo gparted /dev/sdb
  • expand /home partition to the maximum
  • exit from gparted
  • sudo joe /mountpoint/schedina/etc/network/interfaces and CHANGE WLAN IP WITOUTH CHANGING EVERYTHING ELSE.
  • sync, umount
