Description: In this article you will learn how to create kiosks | |
systems with OpenBSD | |
# Introduction | |
Let's have fun doing OpenBSD kiosks! As explained in a recent article, | |
a kiosk is a computer dedicated to display things or to be used | |
interactively without being able to escape the current program. | |
I modified the script `surf-display` which run the web browser `surf` | |
in full screen and run various commands to sanitize the environment to | |
prevent users to escape surf to make it compatible with OpenBSD. | |

# Installation | |
It's rather simple | |
1. `git clone https://tildegit.org/solene/surf-display-openbsd` | |
2. `install -m 555 surf-display-openbsd/bin/surf-display | |
/usr/local/bin/` | |
3. edit `~/.xsession` to use `/usr/local/bin/surf-display` as a window | |
manager | |
You will also need dependencies: | |
``` | |
pkg_add surf wmctrl blackbox xdotool unclutter | |
``` | |
Now, when you log in your user, `surf` will be started automatically, | |
and you can't escape it, so you will need to switch to a TTY if you | |
want to disable it, or through ssh. | |
# Configuration | |
The configuration is relatively simple for a single screen setup. Edit | |
the file `/etc/surf-display` and put the URL you want to display as the | |
value of `DEFAULT_WWW_URI=`, this file will be loaded by `surf-display` | |
when it runs, otherwise OpenBSD website will be displayed. | |
# Conclusion | |
It's still a bit rough for OpenBSD, I'd like to add xprintidle to | |
automatically restart the session if the user has been inactive, but | |
it's working really well already! |
