OpenNSA NSI scripts that can be used e.g. with NA2 exec plugin. In general they turn execution of onsa client from OpenNSA into one-shot operation that returns error codes or exits with status 0.
The scripts require an installation of OpenNSA somewhere and adjusting the env.bash script. All scripts take some command-line parameters, using -h will explain the use. For testing provisioning requests there is a special -l params.sh option that sources an additional file filled with sane values for provisioning a connection.
