Hola a todos/as.
Escribo para ver si alguien tiene alguna solución para un problema que tengo al intentar hacer una conexión "ssh". He utiilizado el código que aparece en la siguiente página http://www.jscape.com/articles/ssh_using_java.html
Y me encuentro con el problema siguiente:
java.lang.UnsupportedOperationException: Not supported yet.2
