Oh not this one again. OpenSSH already removed support for things used
by some devices. It is annoying but the world didn't end - if you need
to use some separate legacyssh binary (sometimes spelt 'p l i n k') to
connect it acts as a good reminder that you're not really using a secure
protocol for that connection.
