Examples of ch.ethz.ssh2.SCPClient

com.trilead.ssh2.SCPClient
A very basic SCPClient that can be used to copy files from/to the SSH-2 server. On the server side, the "scp" program must be in the PATH.
This scp client is thread safe - you can download (and upload) different sets of files concurrently without any troubles. The SCPClient is actually mapping every request to a distinct {@link Session}. @author Christian Plattner, plattner@inf.ethz.ch @version $Id: SCPClient.java,v 1.11 2006/08/02 11:57:12 cplattne Exp $
