- Log into the system as root.
- Open a terminal window and mount the CDROM with the command:-
mount /dev/cdrom/mnt /cdrom
- Run the install script:-
||QWT Graph widgets for QT widget set
||BEAM Astro FFT system
Configuring the System
The basic system will have been installed to system defaults. It is now necessary
to setup the system to run the Astro FFT system. The configuration process
is performed by the AstroFFT script file astroConfig. This sets
up system configuration files, adds the "astro" user and starts up system
daemon processes including the astroFFT control process.
This can be done by performing the following:
The system is now ready for use. For further AstroFFT configuration please
refer to the Software Management
- Log into the system as root.
- Open a terminal window and run the command :-
- Logout of the system and reboot.
Further System Configuration
The Astrofft daemon process has a configuration file named /etc/astrofft.conf.
This file defines the directory where the AstroFft data files are stored
and the list of network clients that are allowed access to the Astrofft
daemon. More information on this is in the
AstroFft Software API Manual
The AstroFft software is installed in the /usr/astro directory.
