Introduction

OSStrap is a bootstrap tool that automatically reconfigures an OpenSim daemon under FreeBSD systems. It relies upon rc.conf to set the hostname as well as other command line tools to extract network settings from the environment.

When the OS boots, the Regions.ini file is automatically generated and sets-up the following regions with the following names:

Arber
Baer
Cuvier
Dart

Based on the set hostname in rc.conf, the network address is mapped to the set hostname which requires that the OS acquires a routable IP address. By default, the script assumes that the hostname is set to snowyowl initially. Users may opt to modify the hostname or relocate the machine but the script adapts accordingly and based on regex patterns it changes the appropriate configuration files dynamically.

Applications

Portable OpenSIM daemon. We have created this for the BIO-SE group using our own OpenSIM distribution bundled in a Virtual Machine running FreeBSD9.
