Lookyloo

Lookyloo is a web interface allowing to scrape a website and then displays a tree of domains calling each other.

What is that name?!

1. People who just come to look.
2. People who go out of their way to look at people or something often causing crowds and more disruption.
3. People who enjoy staring at watching other peoples misfortune. Oftentimes car onlookers to car accidents.
Same as Looky Lou; often spelled as Looky-loo (hyphen) or lookylou
In L.A. usually the lookyloo's cause more accidents by not paying full attention to what is ahead of them.

Implementation details

This code is very heavily inspired by https://github.com/etetoolkit/webplugin and adapted to use flask as backend.

Installation of har2tree

The core dependency is ETE Toolkit, which you can install following the guide on the official website: http://etetoolkit.org/download/

We install python-qt4 and python3-pyqt4 systemwide because they are painful to install manually:

sudo apt-get install python-qt4 python3-pyqt4

Server install (Ubuntu 16.04):

You need to install a basic X server:

apt-get install xserver-xorg xdm xfonts-base xfonts-100dpi xfonts-75dpi

And configure xdm in /etc/X11/xdm/xdm-config:

Replace:

DisplayManager*authorize:      true

with

DisplayManager*authorize:      false

And restart xdm:

service xdm restart

Installation of scrapysplashwrapper

You need a running splash instance, preferably on docker: https://splash.readthedocs.io/en/stable/install.html

sudo apt install docker.io
sudo docker pull scrapinghub/splash
sudo docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash

Installation of the whole thing

If you have pew installed you can enable the use of pyqt4 installed globally this way (instead of installing PyQT4 manually):

pew toggleglobalsitepackages  # PyQt4 is not easily installable in a virtualenv
pip install -r requirements.txt
pip install -e .

Run the app locally

export DISPLAY=:0
export FLASK_APP=lookyloo
flask run

With a reverse proxy (Nginx)

pip install uwsgi

Config files

You have to configure the two following files:

  • etc/nginxsites-available/lookyloo
  • etc/systemd/system/lookyloo.service

And copy them to the appropriate directories and run the following command: sudo ln -s /etc/nginx/sites-available/lookyloo /etc/nginx/sites-enabled

Make sure everything is working:

sudo systemctl start lookyloo
sudo systemctl enable lookyloo
sudo nginx -t
# If it is cool:
sudo service restart nginx
