dropbear suite provides both an ssh server and a client application (dbclient), and represents a light alternative to
OpenSSH. Since it has a small footprint and uses system resources very well, it is generally used on embed devices, with limited memory and processing power (e.g routers or embed devices), where optimization is a key factor. It provides a lot features, like, for example,
X11 forwarding, and it is fully compatible with the
OpenSSH public key authentication.
