  The SAP error message OIUT2323, which indicates "SSH invalid method in & & & &," typically relates to issues with Secure Shell (SSH) connections in the context of SAP systems. This error can occur when there is a problem with the SSH configuration or when the method of authentication being used is not supported or recognized.
  Causes:
  
  Unsupported SSH Protocol Version: The SSH client and server may be using incompatible versions of the SSH protocol.
  Invalid Authentication Method: The authentication method specified in the SSH configuration may not be supported or correctly configured.
  Configuration Issues: There may be issues in the SSH configuration files (e.g., sshd_config on the server side) that prevent proper authentication.
  Network Issues: Firewalls or network configurations may be blocking the SSH connection or specific methods of authentication.
  Key Issues: If using key-based authentication, the keys may not be correctly set up or may not match.
  
  Solutions:
  
  
  Check SSH Configuration:
  
  Review the SSH server configuration file (usually located at /etc/ssh/sshd_config) to ensure that the supported authentication methods are correctly specified.
  Ensure that the PubkeyAuthentication and PasswordAuthentication options are set according to your requirements.
  
  
  
  Update SSH Client and Server:
  
  Ensure that both the SSH client and server are updated to the latest versions to support the latest protocols and methods.
  
  
  
  Verify Authentication Methods:
  
  Check the authentication methods being used. If using key-based authentication, ensure that the public key is correctly placed in the ~/.ssh/authorized_keys file on the server.
  
  
  
  Test SSH Connection:
  
  Use command-line tools to test the SSH connection and see if you can connect manually. This can help identify if the issue is with the SAP system or the SSH setup.
