Cisco/Linksys released the WRT54G wireless router in 2003. In the same year, it was discovered that its IOS is based on Linux. However, Linux is released under the GPL license. According to this license, Cisco should disclose the source code of the WRT54G IOS. In March 2003, Cisco was forced to disclose the source code of the WRT54G under public pressure. Since then there have been some third-party router firmware based on Cisco source code, OpenWrt is one of them.
OpenWrt can be described as an embedded Linux distribution (mainstream router firmware has dd-wrt, tomato, openwrt) instead of trying to build a single, static system. OpenWrt's package management provides a fully writable file system, from the application vendor's choice and configuration, and allows you to customize the device to suit any application.
For developers, OpenWrt uses a framework to build applications without having to build a complete firmware to support it; for users, this means they have full customization capabilities and can use the device in ways never before possible.
The Linux world is so big that it is too big to talk about. OpenWrt is just an embedded Linux distribution.
OpenWrt grew out in 2004. From 2005 to 2007, the initial stable version was called White Russian, after which Kamikaze continued to 2010, Backfire to 2013, and then AtTItude Adjustment was released, and the latest version of Barrier Breaker is already under continuous development, allegedly soon. release. The predecessor of its predecessor, UNIX, developed step by step, slowly awakened... Is there a kind of "Skynet" to be thicker!
First of all, openWRT can achieve some of the more mainstream features.
Wireless audit
Offline download
Wireless audio
Photocopy sharing
Deploy servers (blog community, etc.)
Special dialing (Ruijie, H3C, etc.)
Wireless monitoring
Over the Great Wall
Wireless print sharing
Of course, there are some gray mainstream gameplay, such as ad filtering, deploying KMS to activate Microsoft products, mosquito repellent, WEB billing authentication, and advanced WRTnode, remote control smart car and the like.

OpenWRT useHow to say it, mention it, maybe everyone may be a bit strange, but mentioning its brother Android, probably no one knows. In contrast: "OpenWrt has a user experience comparable to desktop-level Linux and modern mobile operating system (Android), completely avoiding the temper and boring of traditional embedded Linux, making a small router truly complete, modern, open The computing system has lowered the barriers to entry and has generated a large number of non-embedded professional enthusiasts. The developers of the OpenWrt framework and a wide range of code contributors have also made OpenWrt a concept of desktop and modern operating systems. A well-respected and well-respected leader in embedded Linux.
Specifically, OpenWRT can do all the functions that the router can do. [On the market, except for the official firmware, the third-party firmware mainly includes OpenWRT (the most powerful function), TT (good stability) and DD (with the relay). "Famous"). OpenWRT advanced functions: do USB camera, mount mobile hard disk / U disk, BT download, 3G network card (well, this official firmware is also barely feasible), single number dialing (this is effective depends on the local ISP), binding domain name remote control, Samba/DLNA home NAS sharing, private cloud synchronization, FTP, personal website/server, etc.
High-end gameplay, you can change the export IP (you know, think about going out, there is a portable route with this function), prevent DNS pollution (and vice versa), do programmers, intelligent robots " "Brain" (draw the experience of the last failed submission, should not write, do not write, hehe)... OpenWrt community organizer Gregers Petersen mentioned in an interview, "In addition to the traditional router use, in the smart home control equipment In many fields, such as robots, aircraft, industrial control equipment, voIP equipment, etc., there are enthusiasts and commercial projects using OpenWrt, and even fans have completely transplanted the Android system and actually got through the phone. And Arduino Yun grafted on OpenWrt It is a very simple possibility to realize that Linux interacts with the physical world, which gives OpenWrt a larger imagination. In the new wave of smart devices and robots, the value of OpenWrt has become more and more important. Compared to the Android system, OpenWrt is considered to be a platform that is more adaptable to smart devices and robots, and its direct native binary generation. Codes have higher computational efficiency".
