As oTree Virtual Machine Manager provides useful commands to
administrators of the oTree Virtual Machine Image, it requires superuser
rights to perform its actions. Therefore, install
ovmm under the provided
We created a Virtualbox image for oTree users based on ovmm and on “Ubuntu 16.04.2 Server 64bit” and comes with three desktops Gnome, LXDE, and fluxbox to allow it to work on systems with varying level RAM.
The images all contain a user account called
otreeadmin that comes
preconfigured with the set of end user commands provided by ovmm. The
images further each contain an account
ovmmadmin from where ovmm can be
used to create more accounts.
You find the images here: oTree Virtual Machine Images
We also spent some time on trying to figure out what tools could be useful to the end users. Therefore all images with the following tools preinstalled.
|Giggle:||GUI for Git,|
|Atom:||Great free IDE with many plugins,|
|pgAdmin 3:||GUI for postreSQL database systems|
The following components need to be present on your system to use
|ftp:||required for ftp access to the account|
|postgresql:||database server + development packages|
|pip:||package manager for Python|
|python3-venv:||virtual environment for Python 3|
|redis-server:||remote dictionary server|
|samba:||Windows share access|
|mailutils:||sending mails if otree stops unexpectedly|
|ssh:||remote shell access|
|xterm:||Linux terminal emulator|
|zenity:||GTK 3.0 dialog handler|
In most Debian based Linux environments you can install these packages from the repositories like so:
$ sudo apt install ftp nginx samba screen mailutils ssh ufw postgresql git \ postgresql-server-dev-all python3-pip zenity \ python3-venv redis-server xterm
Please see the documentation of your Linux distribution for help.
To install oTree Virtual Machine Manager, run this command in your terminal:

Recommendations for Additional Software¶
To enhance the working experience for the oTree end user we recommend to also install the following software packages.
|chromium:||Chromium browser is the Open Source version of Chrome browser. As it is the most frequently used browser on the web it is the recommended testing environment for your oTree apps.|
|conky:||Desktop system monitor. ovmm statics provides a preconfigured conky configuration file which is unzipped into the user’s $HOME directory and provides helpful system information while running oTree.|
|Atom:||Open Source IDE with many features.|
|pgAdmin III:||Graphical user interface for postgreSQL database servers. Helps with understanding oTree and data recovery if something goes wrong.|
In Ubuntu and official derivatives you can install chromium, conky, and pgAdmin via the package manager, like so:
$ sudo apt-get install conky-all chromium-browser pgadmin3
It is recommended to obtain LightTable from the official website as the community packages are deprecated.
