A similar tool Hydra has no problems with Dropbear. Name dropbear - lightweight SSH2 server Synopsis dropbear -FEmwsgjki -b banner -d dsskey -r rsakey -p address:port Description dropbear is a SSH 2 server designed to be small enough to be used in small memory environments, while still being functional and secure enough for general use. On a related note, Ncrack, the standalone brute-force passsword cracking tool, also fails against Dropbear SSH servers for the same reason. Update (): This is now fixed in the Nmap github repo Nmap done: 1 IP address (1 host up) scanned in 2.22 seconds Dropbear 2011.54 released Forum » Discussions / Request for features » Dropbear 2011.

The problem is the script is a little too rigid in the way it expects the communications to go. Unfortunately the default ssh2-enum-algos script does not work against a Dropbear server. The embedded Linux build frameworks Yocto and Buildroot both provide Dropbear as an SSH server option and it is the default for their smaller systems. Router firmware Asuswrt and third-party versions of Asuswrt like Asuswrt-merlin also use Dropbear. Host like:, , and server like 8.8.8.8, 2. The SSH server can be connected directly from Unix with the ssh command line program or other SSH client programs: Address Your IP address (e.g.: 192.168.0.100) Username root. Enter the Server or Host in the field below. Remark: You can swap or change your SSH server at any time using DietPi-Software. Port Checker is also used to Proxy Checker, DNS Server Checker and VPN port checker and many more. In embedded Linux systems it is not uncommon to use Dropbear as the SSH server because of the smaller footprint it has over OpenSSH.įor example, the open-source firewall/router pfSense uses Dropbear SSH. Port checker is feature to check the port is open or not from the server side. Nmap done: 1 IP address (1 host up) scanned in 2.25 seconds
