ssh2-python is unable to establish connection with RHEL 9 SSHD #176

Closed ogajduse closed 2 years ago

Bug reports

Steps to reproduce:

  1. Run the ssh2-python example python publickey_fromfile.py --host 10.1.5.60 -u root /home/.ssh/id_rsa_foreman_proxy ls against RHEL 9 system
  2. client side: ssh2.exceptions.AuthenticationError, server side: sshd[7101]: userauth_pubkey: key type ssh-rsa not in PubkeyAcceptedAlgorithms [preauth]

Expected behaviour: Client connects to the host, and runs ls.

Actual behaviour: AuthenticationError was thrown

Additional info: Versions: ssh2-python 0.27.0, Fedora 36, Python 3.10.5

I can not see this issue when using the CLI OpenSSH client. Also, I can not see it when using the publickey_fromfile.py and ed25519 key type. And the issue does not pop up even when using another example: python password_auth.py --host 10.1.5.60 -u root mysecretpass ls
