SSH connectivity can be achieved by creating an SSH user account on each target host. If you create the optional trust relationship between an agent host and a remote host, certain CA Process Automation-specific configuration requirements apply.
When a request to a remote host is processed, the following properties are read:
CA Process Automation attempts an SSH connection from the agent host to the remote host specified in the request. The first access attempt is made with the configured credentials of the user account. If this attempt fails, a second attempt is made using key-based authentication. To use SSH public key authentication with CA Process Automation, the name of the private key file must match the name on the user account. If a passphrase is specified when creating the keys, the passphrase must match the password on the user account. Thus, the following two fields serve double duty.
Is the user name for the user account that is used when authentication is based on SSH credentials.
Is also the name of the key file that stores the SSH private key at the path configured as SSH Keys Path, when configured.
Is the password for the user account that is used when SSH credentials are used for authentication.
Is also the passphrase that is used when the SSH public key is used for authentication.
Follow these guidelines when creating a trust relationship from the local host to the remote host:
ssh-keygen -t dsa -b 1024 -f user_name
