The OpenWrt system on industrial sim card router
The E-Lins router supports OpenWrt system. What is OpenWrt?
OpenWrt can be described as an embedded Linux distribution. (mainstream router firmware dd-wrt, tomato, OpenWrt, padavan four class) compared to a single, static system, OpenWrt package management provides a completely writable file system, from the application suppliers selection and configuration, and allows you to customize the device, so as to adapt to any application.
The OpenWrt project started in January 2004. The first version was based on the Linksys GPL source code and the Buildroot project in Ulibc. This version is called the "stable" version and is still used by many projects on the web today. The better known are freifunk-firmware and Sip@Home.
In early 2005, some new developers joined the project, and a few months later they released the first "experimental" version, which, unlike the previous version, almost completely ditched the Linksys GPL source code and used Buildroot2 as the core technology. OpenWrt will be completely modular, OpenWrt using Linux official release of the core source code (2.4.30), plus some patches and network drivers, the development team more OpenWrt added a number of free tools, can directly write Image into Flash (MTD). Set up wireless and VLAN switching capabilities. This version is called "White Russian" and version 1.0 was released in late 2005.
What are the features of the OpenWrt system?
OpenWrt is a highly modular, highly automated and embedded Linux system with strong network components and scalability. It is often used in industrial devices, phones, small robots, smart homes, routers and VoIP devices. The OpenWrt SDK simplifies the process of developing more than 100 compiled software, and the number is growing.
Unlike many other distributions for routers, OpenWrt is a fully functional, easily modified router operating system written from scratch. In practice, this means that you can use the features you want without adding other cumbersome features, and the Linux kernel that supports them is much newer than most distributions.
