Etherbox

(Based on a setup used for working sessions at constant. MM)

Copy the starting image

Downloaded from https://www.raspberrypi.org/downloads/raspbian/

Based on the "lite" image (zip or torrent). As of 20 Jan 2018, this is Raspian "Stretch" lite.

The **lite** image has no desktop / windows session.

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

You could use Etcher.io as well

Enable SSH

SSH is no longer on by default!

Before putting the SD card in the pi, you can enable ssh. Just create a empty file named "ssh" and save it in the /boot partition of the SD Card.

So mount the SD card and

 cd /media/USERNAME/boot
 touch ssh

Otherwise, you can connect with a screen and run:

sudo raspi-config

Then enable ssh under connectivity.

Find the IP address of the pi

Simplest way is to connect on a wired network that has DHCP and plug both the pi and your laptop into a router with ethernet cables, then type:

   ping raspberrypi.local

And you should be able to see the IP address.

Then you can connect with ssh with either:

   ssh pi@raspberrypi.local

or with the IP address in place of "raspberrypi.local" if you are on the wifi.

Login with the default password "raspberry"

Make it easier to login, with an ssh key

Starting from your laptop (open a new Terminal session if you are connected to the pi):

   ssh-keygen

Choose the defaults. This generates an "ssh key" pair.

Use the ssh-copy-id utility to send it to the pi.

   ssh-copy-id pi@raspberrypi.local

Bring the rest of the software up to date

sudo apt-get update
sudo apt-get upgrade

Change hostname from raspberrypi to etherbox

In 2 places:

   sudo nano /etc/hostname

   sudo nano /etc/hosts

change to:

127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

127.0.1.1       etherbox

Best to reboot after this, otherwise it gives warnings all the time.

sudo reboot

Assign Static Ip Adress to the Pi

For that, you need to modify a file named 'dhcpcd.conf'. But first, you need to backup this file :

cd /etc/
sudo cp dhcpcd.conf ddhcpcd.conf.original

Then modify the 'dhcpcd.conf' :

 sudo nano dhcpcd.conf

Then find this and replace (with your value) :

# Example static IP configuration:
interface eth0
static ip_address=192.168.1.5/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
static routers=192.168.1.1
static domain_name_servers=192.168.1.1

Where 192.168.1.5/24 is the new Ip address of your Pi.

At last, reboot your Pi :

sudo reboot

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.conf

    ServerAdmin webmaster@localhost
    # DocumentRoot /var/www/html
    DocumentRoot /home/pi
    <Directory /home/pi>
           Options Indexes FollowSymLinks
           AllowOverride none
           Require all granted
    </Directory>

    HeaderName /include/HEADER.shtml
    ReadmeName README.html

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

sudo service apache2 reload

droptoupload.cgi

Drop to upload is a CGI python script that allows users to drop files to upload them in the apache directory listings.

First enable the cgi-bin with apache

sudo a2enmod cgi
sudo systemctl restart apache2

Download the script to the cgi-bin.

   cd /usr/lib/cgi-bin
   sudo wget https://gitlab.constantvzw.org/aa/etherbox/raw/master/usr/lib/cgi-bin/droptoupload.cgi
   sudo chmod +x droptoupload.cgi

You can test 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 (next step) includes a link to this cgi.

/home/pi/include/HEADER.shtml

nano /home/pi/include/HEADER.shtml

(don't use sudo)

<source lang="html"> <script src="/cgi-bin/droptoupload.cgi"></script> <style> body { background: #38b8e9; color: black; } a { color: white; }

1. logo {

white-space: pre; font-family: monospace; } </style>

   document.body.insertBefore(p[i], t);
 }

}); </script> </source>

Better permissions with facl

setfacl

sudo apt install acl
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

Install 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

Les fichiers se trouvent dans opt/etherpad/var sous forme d'un seul fichier "dirtyDB" - > You should use a dedicated database such as "mysql", if you are planning on using etherpad-in a production environment.

Create your setting file.

cd etherpad
sudo --user etherpad cp settings.json.template settings.json

sudo cp settings.json.template settings.json

then, desactivate the dirty.db file and configure the mysql database

sudo --user etherpad nano settings.json

Find and change this part :

  //The Type of the database. You can choose between dirty, postgres, sqlite and mysql
  //You shouldn't use "dirty" for for anything else than testing or development
 /* "dbType" : "dirty",
  //the database specific settings
  "dbSettings" : {
                   "filename" : "var/dirty.db"
                 },
*/
  //An Example of MySQL Configuration
   "dbType" : "mysql",
   "dbSettings" : {
                    "user"    : "etherpaduser",
                    "host"    : "localhost",
                    "password": "etherpadpass",
                    "database": "etherpad",
                    "charset" : "utf8mb4"
                  },

Set up Mysql

First thing to do is to install MySQL :

sudo apt-get install mysql-server

Then create the database, for this we need to login with the Root user (super-user) :

sudo su

Run mysql  :

mysql

Then create the database and the user 'etherpaduser' with the password 'etherpadpass' :

create database etherpad;
grant all on etherpad.* to 'etherpaduser'@'localhost' identified by 'etherpadpass';

Use Ctrl-D to quit mysql. And exit to quit su.

Just to test if it works :

mysql -u etherpaduser -p etherpad

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

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

The first time you run the etherpad software it takes a **long** time as it downloads related packages. It may also give quite some warnings, but hopefully no errors.

Setup etherpad to start as a 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, to start once...

sudo systemctl start etherpad

Check if it's working with:

sudo systemctl status etherpad

And finally automatically start on boot:

sudo systemctl enable etherpad

etherdump

Etherdump is a script that dumps all pads to different format text files. It's run periodically by a cron job to create a running archive of the etherpads.

Install deps:

sudo apt install python3-pip
sudo pip3 install python-dateutil jinja2 html5lib

Install from repo:

cd
mkdir Software
cd Software
git clone http://murtaugh@gitlab.constantvzw.org/aa/etherdump.git
cd etherdump
sudo python3 setup.py install

Init the folder

You need the API key. Copy it from:

cat /opt/etherpad/APIKEY.txt

Then...

cd /home/pi
mkdir etherdump
cd etherdump
etherdump init

For the URL use: http://192.168.1.5:9001/

And paste the API key.

Install Pandoc

   sudo apt-get install pandoc

cron.sh

nano /home/pi/cron.sh

<source lang="bash">

1. Dump the etherpad to files

cd etherdump etherdump pull --meta --text --dhtml --pub . --no-raw-ext etherdump index \

 *.meta.json \
 --templatepath /home/pi/include \
 --template etherdump.template.html \
 --title "Erg etherdump" > index2.html

1. Run the makefile

cd /home/pi make </source>

makefile

The makefile defines the "recipe" that turns the pads (when they are named something.md) into HTML. The "%.html: %.md" is an "implicit rule" that defines how any ".md" file (right hand side, or pre-requesite, can be turned into a ".html" file (left hand side, or "target" in the language of the makefile. For this kind of rule the special variables can be really useful (like $< and $@).

This makefile uses the pandoc program to convert markdown to html. This program has LOTS of options is quite powerful. Good documenation on the markdown format, and how pandoc supports it is: http://pandoc.org/MANUAL.html#pandocs-markdown

nano /home/pi/makefile

<source lang="bash"> mdsrc=$(shell ls etherdump/*.md) htmldest=$(mdsrc:%.md=%.html)

all: $(htmldest)

1. $< is the right part input prereq $@ is the target

%.html: %.md pandoc --from markdown \ --standalone \ --section-divs \ --smart \ --css styles.css \ --to html5 \ $< -o $@ </source>
