The following preparations must be made in order to use PPSS in a distributed fasion:
# Create an unprivileged user 'ppss' on the server.
# Create an unprivileged user 'ppss' on each node.
# Generate a SSH key without a pass phrase.
# Add the SSH key to the authorized_keys file of the 'ppss' user on the server.
# Add the SSH key to the authorized_keys file of the 'ppss' user on the client.
# Place PPSS on the server within the PPSS home directory.
*Security*
Please note that usage of SSH keys without pass phrases may pose a security threat if the machines are shared with other users. You must decide for yourself if the security risk that is associated with acceptable for your environment. For example, if a node is compromised, the attacker will have (initially unprivileged) access to the server.
