Server Configuration Files

The SSH Tectia Server for IBM z/OS client and server configuration formats are based on the SSH Tectia Client and Server 4.4. The following files located in the /etc/ssh2 directory are used to store server configuration information:

  • /etc/ssh2/sshd2_config: the main server configuration file
  • /etc/ssh2/ssh_certd_config: the Certificate Validator configuration file
  • /etc/ssh2/hostkey: the default server host private key
  • /etc/ssh2/hostkey.pub: the default server host public key
  • /etc/ssh2/random_seed: the random number seed file for cryptographic operations
  • /etc/ssh2/knownhosts: the global directory for remote client host public keys that are trusted for host-based authentication

The user-specific configurations are stored in each user's $HOME/.ssh2 directory:

  • $HOME/.ssh2/knownhosts: the user-specific directory for remote client host public keys that are trusted for host-based authentication
  • $HOME/.ssh2/authorization: the default authorization file for user public keys
