shh logo

If you work remotely with your computer or server, or you simply want to make some adjustments using your mobile device without having to be physically in front of the machine you want to manage, you already know that one of the best options you have is to create one. SSH (Secure Shell) connection with which you can enter orders from an SSH client to your machine that is acting as an SSH server or even make certain data transfers between one and another.

As you know, there are different software to carry out this type of implementation, and one of the best known in Linux environments is OpenSSH, with which you can have your client server in an easy way. On other occasions we have also talked about Android apps that act as SSH clients or servers to also manage our mobile devices from our ifnromatic equipment or vice versa. But OpenSSH is not the lightest, it is a powerful package, although I honestly prefer it to other alternatives ...

On the other hand, you may be looking for something lighter either due to resource issues on your machine or simply because you do not want to allocate too many resources to implement the connection through the SSH protocol. If so, in this article I introduce you to Dropbear SSH, in case you didn't know about it. With this package you can have a small and lightweight SSH server and client that can totally replace OpenSSH on any POSIX platform, and that includes GNU / Linux distros, BSDs, etc.

dropbear is an open source project published under the MIT license, whose development philosophy has thought that its memory consumption is minimal, something very interesting in embedded or embedded systems, with redirected for X11 sessions, compatible with the authentication file format of OpenSSH public key, capable of redirecting local and remote ports (tunneling) and many other features.
