Getting Started

First download the configuration files from OpenNSA-Tools Examples this contains the following files:

• _opennsa-cli Configuration file for the client CLI, which should go to ~/.opennsa-cli
• example-internal.nrm Defines the mapping of the OpenNSA available ports to physical ports for the example topology
• example-topology.nrm Describes an example topology.
• opennsa.conf Configuration file for the server. Use in your current directory
• start_opennsa.tac Startup file for Twisted

Edit the opennsa-cli file to point to the right topology file.

---

This short guide uses an alternate CLI, which should be installed in your path. With the cli config file in your homedirectory and the four topology files for the server in the local directory, you can execute the following to start the server:

twistd -ny start_opennsa.tac

This starts up the server in debug mode (-n) so that you can see the output. A first request can then be sent to the server using:

onsa-jeroen -r exampledomain A1 exampledomain A2

This requests a local connection between A1 and A2 on the exampledomain.

Or if you prefer you can also use the opennsa included utility:

 onsa reserve -t example-topology.owl -n exampledomain -s exampledomain:A1 -d exampledomain:A2

Your console should show something like this:
