Changes since OpenSSH 6.4 ========================= This is a feature-focused release. New features: * ssh(1), sshd(8): Add support for key exchange using elliptic-curve Diffie Hellman in Daniel Bernstein's Curve25519. This key exchange method is the default when both the client and server support it. * ssh(1), sshd(8): Add support for Ed25519 as a public key type. Ed25519 is a

Hello all, It seems that RhostsAuthentication does not work on non-default port no matter what when connecting from OpenSSH (2.1.1, 2.2.0 tried) either with protocol 1 or protocol 2 (shouldn't work either..). _However_ when connecting with SSH.COM Ltd's ssh, RhostsAuthentication works just fine! Checking the port number of ssh client you can see that OpenSSH doesn't assign
