Initial image + setup

Based on 2017-04-10-raspian-jessie-lite.zip

unzip -p 2017-04-10-raspbian-jessie-lite.zip | pv | sudo dd of=/dev/sdc bs=4M

SSH is no longer on by default! So need to connect with a screen first time and turn this on.

sudo raspi-config

Enable ssh under connectivity.

Bring the rest of the software up to date.

sudo apt-get update
sudo apt-get upgrade

Setup apache to serve the root with custom header + readme's

sudo apt-get install apache2
cd /etc/apache2/sites-available
sudo nano 000-default
    ServerAdmin webmaster@localhost
    # DocumentRoot /var/www/html
    DocumentRoot /
    <Directory />
           Options Indexes FollowSymLinks
           AllowOverride none
           Require all granted
    </Directory>

    HeaderName /home/pi/include/HEADER.shtml
    ReadmeName README.html

NB: Sets the HeaderName and ReadmeName directives (part of mod_autoindex).

sudo service apache2 reload

droptoupload.cgi

sudo a2enmod cgi
sudo service apache2 restart

Placed 'droptoupload.cgi' in /usr/lib/cgi-bin and tried running it with:

./droptoupload.cgi

Like this is just outputs an HTML form. Looking at http://etherbox.local/cgi-bin/droptoupload.cgi should also display an upload form.

The HEADER.shtml includes a link to this cgi.

HEADER.shtml

<script src="/cgi-bin/droptoupload.cgi"></script>
<style>

      t = document.getElementsByTagName("table")[0];

    document.body.insertBefore(p[i], t);
  }
});
</script>

Better permissions with facl

setfacl

sudo addgroup pi www-data

sudo setfacl -Rm g:www-data:rwX /home/pi
sudo setfacl -d -Rm g:www-data:rwX /home/pi

Unfortunately, I had problems then with permissions on the .ssh folder (preventing keys to be used). To remove the fact on just this folder:

sudo chmod g-w /home/pi

Set up etherpad

And the version of "nodejs" is now 0.10.29~dfsg-2. So let's try it with etherpad...

sudo apt-get install npm git

sudo ln -s /usr/bin/nodejs /usr/bin/node

cd /opt
sudo git clone https://github.com/ether/etherpad-lite.git
sudo mv etherpad-lite etherpad

# TODO: don't create home folder! ... find option
sudo adduser --system --home=/opt/etherpad --group etherpad
sudo chown -R etherpad:etherpad etherpad

Used password VJ.

Run etherpad for the first time as the etherpad user...

cd /opt/etherpad
sudo --user etherpad bin/run.sh

Following the first recipe on this page about deploying etherpad as a systemd service

sudo nano /etc/systemd/system/etherpad.service
[Unit]
Description=Etherpad-lite, the collaborative editor.
After=syslog.target network.target

[Service]
Type=simple
User=etherpad
Group=etherpad
WorkingDirectory=/opt/etherpad
ExecStart=/usr/bin/nodejs /opt/etherpad/node_modules/ep_etherpad-lite/node/server.js
Restart=always

[Install]
WantedBy=multi-user.target

After this,

sudo service etherpad start

Seems to work! Apparently it's the same as:

systemctl start etherpad-lite

And to start on boot:

systemctl enable etherpad-lite

etherdump

System wide installation of etherdump

Install deps:

sudo apt install python-pip python-dev
sudo pip install python-dateutil jinja2 html5lib

Install from repo:

git clone http://murtaugh@gitlab.constantvzw.org/aa/etherdump.git
cd etherdump
sudo python setup.py install

Setup the folder

cd /home/pi
mkdir etherdump
cd etherdump
etherdump init

Type in:

http://etherbox.local:9001/

And paste the API key. (Look at: http://etherbox.local/opt/etherpad/APIKEY.txt)

styles.css + versions.js

scp styles.css versions.js pi@etherbox.local:etherdump/lib

The URLs of these files are options to the etherdump pull command and should match.

etherdump.sh + cron

Make the script that runs automatically.

nano etherdump.sh
#!/bin/bash
# PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
cd /home/pi/etherdump
etherdump pull --all --pub /home/pi/etherdump --css lib/styles.css --script lib/versions.js
etherdump index *.meta.json > index.html

And set it to run every 5 minutes

crontab -e
PATH=/home/pi/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# m h  dom mon dow   command
*/5 * * * * /home/pi/etherdump.sh > /home/pi/cron.log.txt 2>&1

The PATH is important. It can also be in the etherdump.sh but basically should match what you see when you "echo $PATH" (for the script to run in the same way as for the pi user).

Other software

sudo apt-get install emacs-nox screen pdftk pandoc texlive-latex-recommended texlive-fonts-recommended
sudo pip install csvkit

To install

What about

The current version of pandoc in this raspbian is 1.12.4.2~dfsg-1+b3 We will use latex for PDF generation (via pandoc)

(which is way better than 1.9 of the previous raspian, and even beats the instructions for compiling 1.11.1)

MORE

sudo apt-get install pandoc texlive-latex-recommended texlive-fonts-recommended 

Was able to:

pandoc --from markdown hello.markdown -o hello.pdf

Access point

Taken from this "ultimate" guide

apt-get install dnsmasq wireless-tools hostapd

# the next wasn't necessary for jessie, but for completeness..
RPI3 broadcom chip 
apt-get install firmware-brcm80211
rmmod brcmfmac
modprobe brcmfmac

Give fixed IP to wlan0 interface, edit /etc/network/interfaces switch off the built in stuff and add (section 2):

auto eth0
allow-hotplug eth0
iface etho inet dhcp

#################################
# 1. ORIGINAL settings... use wpa_supplicant for client mode
#allow-hotplug wlan0
#iface wlan0 inet manual
#    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
#
#################################
# 2. Fixed IP address (for hotspot / hostapd)
auto wlan0
iface wlan0 inet static
address 10.9.8.7
netmask 255.255.255.0
#################################

Replace /etc/dnsmasq.conf with:

interface=wlan0
dhcp-range=10.9.8.10,50.9.8.254,12h
address=/#/10.9.8.7
no-resolv

Edit /etc/hostapd/hostapd.conf file (adjust depending on driver/hardware)

interface=wlan0
driver=nl80211
ssid=WiFeels
hw_mode=g
channel=6

Edit /etc/default/hostapd and add

DAEMON_CONF="/etc/hostapd/hostapd.conf"

Make hostapd start at boot

update-rc.d hostapd defaults

Reboot.

Makeserver + etherpad (experimental!)

Ingredients

Key question: Makeserver as a separate view ?! (probably)

TRY as 2 separate things ... basically AS IS...

Install:

cd /home/pi/software
git clone http://murtaugh@gitlab.constantvzw.org/aa/makeserver.git
cd makeserver
git submodule init
git submodule update
sudo pip install twisted jinja2

BUGFIX with twisted / SSL issues:

sudo pip install twisted[tls]

DIDN"T FIX sudo pip install twisted==16.0.0

Seems to work!
