Error on host key detection on some boxes #13271

Closed LKHN closed 5 months ago

LKHN commented 8 months ago

Considering the ssh-ed25519 is supported, the new supports_key_type? method returns ssh-rsa on some boxes. I can observe the issue on the generic/rocky8 and generic/rhel8 boxes but It successfully identifies the ssh-ed25519 as supported on almalinux/8 box.

Debug output

:host_key=>["rsa-sha2-512", "rsa-sha2-256", "ssh-rsa"]

Expected behavior

Box: almalinux/8

Since we can see the ssh-ed25519 listed on the output of this command:

$ sudo sshd -T | grep -Ei '^hostkeyalgorithms'
hostkeyalgorithms ecdsa-sha2-nistp256-cert-v01@openssh.com,ecdsa-sha2-nistp384-cert-v01@openssh.com,ecdsa-sha2-nistp521-cert-v01@openssh.com,ssh-ed25519-cert-v01@openssh.com,rsa-sha2-512-cert-v01@openssh.com,rsa-sha2-256-cert-v01@openssh.com,ssh-rsa-cert-v01@openssh.com,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa

It should be listed and the new ssh keypair is generated in ssh-ed255519:

:host_key=>["rsa-sha2-512", "rsa-sha2-256", "ssh-rsa", "ecdsa-sha2-nistp256", "ssh-ed25519"]
