"Description-en: administer multiple ssh or rsh shells simultaneously
  ClusterSSH (cssh, crsh, ctel) allows you to control multiple ssh, rsh
  or telnet sessions from a single input window.  You can also configure
  clusters of machines for easy invocation and interact with individual
  terminal windows during a session."
