Design and Implementation of Linux Based Vsat Monitoring System

In this book, a developed and implemented VSAT monitoring system has been illustrated, which consists of a client program that runs on the host PC (Linux Fedora core3), and a server program that runs on the targeted VSAT router, the iDirect 3000 series - with ARM (Advanced RISC Machine) processor. Both programs are Linux applications implemented in C/C++ using GCC (GNU Compiler Collection) and cross compiler. The cross compiler was built in the host to after-testing a compatible combination of glibc (GNU C library), binutils (binary utilities), kernel version and GCC itself. The server program monitors the bandwidth usage, keeps a history of (download and upload) rates and modem activities such as BER (Bit Error Rate), memory, disk usage, and the uptime. It sends the monitored data via TPC/IP network using secure shell protocol (SSH) and secure copy (SCP) to an Apache web server. The web server on the host displays the results as charts and numbers using hypertext preprocessor (PHP) to the network administrator.
