DSSH was written as a direct replacement for the
OpenSSH client. It adds SSH over SSH tunneling
capabilities (for example, to log in to a network
hidden by a firewall), scripting support (using
BeanShell), an advanced agent (which allows storing
of passwords) and "su -" interactive logging for
machines that have disabled direct root login. All
of this was done to enable automated scripting and
logging to many machines based on a few simple
rules.
