Linux vs Unix

 
  home->Sweet Home  

Welcome to the Etlinux web site

What is Etlinux?

Etlinux is a complete Linux-based system designed to run on very small industrial computers. It has been designed to be small, modular, flexible and complete. Its reduced memory and disk requirements make it ideal for all cost-sensitive situations, while at the same time its modularity and completeness give the full power of unix even for embedded applications.




What is Etlinux useful for?

Etlinux is ideal in all embedded system applications where advanced unix facilities are a must: preemptive multitasking, multithreading, memory protection, fast I/O, enhanced reliability, speed, ...
Moreover, source code availability is a guarantee for the longevity of Etlinux based products.
But perhaps the greatest advantage over competitors is given by the enormous and proven availability of advanced development tools, documentation and sources, giving an effective edge to the developer and reducing the time to market. In fact the availability of constantly updated quality C/C++ compilers, debuggers, libraries, interpreted languages, and other tools is the most compelling reason to switch away from old proprietary embedded development environments.


Etlinux specific features

Etlinux has some unique features, that distinguish it from other linux-based embedded solutions:
  • embedded cgi-capable WEB server
  • a telnet server
  • an email server, with the ability to execute commands sent by email from a remote site
  • CORBA support
  • easy-to-use remote file management
  • the powerful Tcl scripting language
  • a flexible package selection scheme, allowing an easy customization of the system
  • source code available for every component



Requirement

Minimal requirements for an Etlinux system are amazingly reduced:
  • Intel-compatible 386SX processor (or better)
  • 2MB of RAM
  • 2MB of disk (HD or M-Systems DiskOnChip)



Is it free?

Like every product released by Prosa Srl, Etlinux is free software and is distributed with full source code. Our code is released under the GENERAL PUBLIC LICENSE (GPL) (some accompanying packages have different licenses, but they all qualify as Open Source).
Etlinux development has been sponsored by EuroTech Spa (http://www.eurotech.it), in order to have a reliable Operating System for their own embedded PC/104 systems.
Although Etlinux includes device drivers for EuroTech peripherals, it is pretty general, and can run on almost any Intel 80x86 based industry standard PC.
