Preshell daemon

C++ metaprogramming shell daemon

This repository contains a setup script for the Metashell and Preshell online demos on an Ubuntu server. You can use it to host your own online demo of the shells.

Setting your server up

• Install Ubuntu server 14.04

• Download the content of this repository

• Run install.sh. This will install the dependent packages, create the daemons and start them.

• The Metashell demo will be listening on port 4202

• The Preshell demo will be listening on port 4201

• The demos use ShellInABox, which gets installed on your server and is listening on port 4200 by default. To stop it run sudo /etc/init.d/shellinabox stop. To avoid it being started during system startup run sudo update-rc.d shellinabox disable

The services providing the demo

The demo is provided by three services:

• metashell This is a ShellInABox service running Metashell as its shell.
• preshell This is a ShellInABox service running Preshell as its shell.
• shell_demo This is a service periodically updating the C++ headers which can be used from the services and building the latest version of Preshell and Metashell.

The services are using the /usr/local/share/shell_demo directory for downloading the source code of different projects (Metashell, Preshell, libraries that can be used from the shell) and building the Metashell and Preshell binaries.

Starting the demos

The installer configures the demos to be automatically started during system startup. To start them manually run the following commands:

sudo /etc/init.d/shell_demo start
sudo /etc/init.d/preshell start
sudo /etc/init.d/metashell start

Stopping the demos

To stop the demo, you need to stop the three services providing it:

sudo /etc/init.d/shell_demo stop
sudo /etc/init.d/preshell stop
sudo /etc/init.d/metashell stop
