        El uso de SSH es fundamental en las comunicaciones actuales, ya que la mayoría de servicios de red se llevan a cabo sin cifrar. Como consecuencia, cualquiera puede "escuchar" los datos que transferimos o recibimos.

                Establece el número de mensajes solicitando una respuesta (ver la opción anterior) que se enviarán sin  ninguna contestación por parte del cliente. Si se alcanza este límite, sshd desconectará al cliente, terminando la sesión. Es importante hacer constar la diferencia entre los mensajes de comprobación de la existencia del cliente (client alive) y los mensajes KeepAlive (más abajo). Los primeros, se envían a través de un canal encriptado y no pueden ser interceptados. Los últimos, TCP KeepAlive, sí son interceptables y posibilitan que un cliente o servidor tengan conocimiento de cuándo una conexión se ha vuelto inactiva.

                Especifica si el sistema debe enviar mensajes keepalive al otro extremo. Si se envían, la muerte de la conexión o la interrupción en el funcionamiento en una de las máquinas serán notificadas pertinentemente. Sin embargo, esto significa que las conexiones morirán si la ruta cae temporalmente. Por otro lado, si no se envían mensajes keepalive, las sesiones pueden colgarse indefinidamente en el servidor, dejando usuarios fantasma y consumiendo recursos del sistema.

En ese caso, la contraseña suministrada por el usuario puede ser validada contra un KDC Kerberos. Para usar esta opción, el servidor necesita un servtab Kerberos que permita la verificación de la identidad del KDC. Por defecto, el valor es "yes".

DocBook es una aplicación XML (también hay una versión SGML) que facilita los sistemas de documentación, al dotar de semática a los textos desde el punto de vista de los sistemas informáticos. Además permite la versatilidad de dar como salida casi cualquier formato documental: LaTeX, TeX, TeXinfo, PDF, RTF, xhtml,...
