Astronomical FFT processing system
System Software installation
This document describes how to install all of the software onto a
Debian "Sarge" Linux based system starting from a bare hardware system.
The basic process
Installing the Linux Operating system
The Linux Debian "Sarge" Operating system should be installed following
the instructions on the Debian web site at: http://www.debian.org. The AstroFft
system uses a number of "optional" packages that are not installed with
a basic installation. These will need to be added when the AstroFft
software is installed.
Installing the BEAM AstroFFT Software
The BEAM AstroFFT software can be installed either by downloading from
the BEAM AstroFFT support site at: https://portal.beam.ltd.uk/support/astrofft
or from AstroFft "Install" CDROM.
The following packages need to be installed:
||AlphaData ADMXRC driver and API
library for FPGA cards. This package is for the 2.4.27-2-386 standard
||BEAM Astro FFT system
|BEAM Astro FFT GUI (This is
optional, it provides a GUI for controlling the system). This package
requires a number of Debina GUI packages including X-Windows, QT, QWT
Install these packages using the command: "dpkg -i <package file
Configuring the System
It is now necessary
to setup the system to run the Astro FFT system. The configuration
is performed by the AstroFFT script file astroConfigDebian.
up system configuration files, and sets up
daemon processes including the astroFFT control process to
start automatically on boot.
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. Alternatively restart the
AstroFft daemons with the commands: "/etc/init.d/admxrc2 restart;
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
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.
