Examples of ch.ethz.ssh2.Session

com.trilead.ssh2.Session
A Session is a remote execution of a program. "Program" means in this context either a shell, an application or a system command. The program may or may not have a tty. Only one single program can be started on a session. However, multiple sessions can be active simultaneously. @author Christian Plattner, plattner@inf.ethz.ch @version $Id: Session.java,v 1.9 2006/02/14 19:43:16 cplattne Exp $
