      ssh_scan

      Introduction

      This tool is light on its dependencies, as it only uses Ruby and BinData. The scanner is simple to use, as it is limited in the number of parameters and options. There is also the ability to show the results on the screen or export the data to a JSON file. The latter is great if you want to do further processing of the details, or simply store them for later comparison.

                              A typical use case for multiplexing is to allow serving several services on one port. Port 443 is commonly used, as that is typically opened on firewalls to allow HTTPS traffic. By multiplexing it, you can also use SSH or other services on the same port.
