#summary PPSS Manual (Distributed)

= Introduction =

To use PPSS in a distributed fasion, The following steps must be performed:

 # Make the necessary preparations on server and nodes.
 # Create a configuration file for PPSS, that will be distributed to nodes.
 # Deploy PPSS to the nodes.
 # Start PPSS on all nodes. 

some preparations need to be made.

== Preparation of server and nodes ==

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.
