Geh of course 9front ssh(1) only seems to supports RSA keys while tinysshd (what I use on unix side) only supports ed25519 keys.
@Haelwenn /элвэн/ :triskell: You don't want to know the shape of the ssh wrapper I use to connect from alyss to all the servers on cfarm to run my build tests. It's the most horrendous pile of hacks I've had to write in a while, so that even antediluvian systems that only support sshv1 are accessible.
