                    java.lang.String localDir,
                    java.lang.String remoteDir,
                    boolean setupNode)

copies a local dir to the remote node via a shell script that uses ssh/rsync

copyDirToNodes

public boolean copyDirToNodes(PlanetLabMgr planetLabApi,
                              java.lang.String[] hostnames,
                              java.lang.String localDir,

                              boolean setupNode)

copies a local dir to the remote nodes via a shell script that uses ssh/rsync

getDirFromNodes

public boolean getDirFromNodes(PlanetLabMgr planetLabApi,
                               java.lang.String[] hostnames,
                               java.lang.String remoteDir,
                               java.lang.String localDir)

Transfers the remote directory from each of the nodes and saves it to the local directory This is done via a shell script that uses scp.

Parameters:

planetLabApi -

remoteDir - - the remote directory which is located at each node

localDir - - the local directory which is used as destination for the remote directories of the nodes. A subdirectory named like the hostname of each node will be created to save the remote dir of the node.

hostnames - - the hostnames of the nodes from which the directory will be copied to your pc

Returns:

true if successful
