In some particular situations, you might be presented with
ssh:// links. Exoscale, for example, provides this on the web management interface.
By default, most browsers wouldn’t know how to open these links, but in most cases it’s as simple as opening ssh in a console.
Registering a protocol handler is an easy solution to this. Once the registry entries below are “installed”, an ssh link will open automatically in a console.
Important: be careful when opening these links and be sure to not hide your browser’s warning. An attacker could make you run commands through such links.
