4. Configuring JNOS

Start the JNOS configuration application by selecting the JNOS from the System submenu of the Applications Menu at the top left of the screen.

A terminal window will appear which requests the root password. Provide the password you offered during first boot:

After a delay, during which information is being gathered from your system, the configuration panel will appear. Fill out all fields in the panel. If an entry is known to be incorrect, it will be red. The "Install JNOS" button will remain inactive until all fields are black. Be aware that the combo boxes (Frequency, County, Quadrant) can be quite slow to appear.

If you are uncertain about the meaning of a particular field, hovering the mouse over the field will bring up a more detailed description of the field:

A description of each field may be found in Appendix B, Field Definitions.
Once all fields are correct, click on the Install JNOS button. This button will not be active if any fields are red.
When you click Install JNOS, you will begin to see some activity in the text window. This takes some time. After several minutes, you will see:
Configuration is done
Configuration files have been created

At this point, configuration is complete. After a delay, the system will shut down. Remove power and then re-apply power. When the system reboots, JNOS will start.
Part of configuration involves creating a jnos_system_account user and giving this user privileges. The privileges will not be available, and hence JNOS cannot start, until the system has been rebooted. The TNC-Pi must be powered off in order to accept new parameters. This is why the Pi is shut down instead of being rebooted.
When JNOS is running, you may view the JNOS console by pressing Ctrl+Alt+F6. Return to the graphical console with Ctrl+Alt+F1.
This, of course, requires that you have the display, keyboard and mouse still attached. Once the system has been configured, there is little reason for this, so at this point, if desired, you can shut down the Pi, remove these accessories, and place it on the operating table connected only to power, your LAN, and the radio.
