5. User Interface
The GPRI-II instrument can be accessed through TCP/IP over the Ethernet connection provided at the
Instrument Controller, or by opening the Pelican case and connecting a computer display and
keyboard/mouse. The latter allows access in case the IP address of the instrument is unknown or any
other communication problem occurs.
5.1 Local Access
To have local access on the Instrument Controller the Pelican case needs to be opened and a computer
screen (VGA) and a Keyboard and Mouse (USB) can be attached. After booting up the instrument the
Ubuntu login screen shows up. The user to login is gpri2. After loging in the standard gnome user
interface is shown. It allows full access on system settings, in particular also the network settings.
5.2 Graphical User Interface
The graphical user interface can be accessed with any recent (Javascript enabled) web browser by
requesting https://192.168.1.73/ (the IP needs to reflect your setting). After logging in as user gpri2,
you have access on system status information, instrument settings etc. The graphical user interface
gives you only access on the most important instrument functions. For full system access use the
terminal access or the local access.
5.3 Terminal Access
The instrument terminal can be accessed through secure shell (ssh). The export of the X11 windows is
supported. You can initiate this feature by logging in with the option -X
(
ssh -X [email protected]
). The terminal access gives you full access on the system.
