The Linux Web Shell is a web-based SSH terminal to access headless (embedded) Linux devices. The Linux Web Shell is implemented as a Mako Server (and Barracuda App Server) application that can export arbitrary Linux command line tools to a web based terminal emulator. This emulator is accessible to any modern web browser and does not require any additional browser plugins.
