[Bug 1280496] Re: ed25519 host key not working on 6.5p1

[cc]

So I did a little more investigating and tested   "ssh <hostname>" and
"ssh localhost"


Also, it seems that the key is HostKeyAlgorithms  in .ssh/config. Search HostKeyAlgorithms in ssh_config


If I manually force it to only use ed25519, then the host key exchange happens over ed25519, else it uses ECDSA.


So there's something strange going on with the setup. Support is there but the defaults are wonky.

Title:
  ed25519 host key not working on 6.5p1

Status in “openssh” package in Ubuntu:
  Incomplete

Bug description:
  So I decided to test out the new ed25519 support on the new release of
  OpenSSH. I generated the necessary keys, added the HostKey line in
  sshd_config and restarted.

  It does not appear to work and could be missing a compile flag
  somewhere.

  Long story short, I can generate the appropriate keys but trying to
  actually use it results in openssh offering ecdsa keys instead.
