Acceso por SSH a red interna con un solo comando

by c4lf4 3 years ago

GNU/Linux ◆ xterm ◆ bash 168 views

En este cast se muestra cómo acceder desde un equipo cliente a una máquina en la red interna (10.0.0.29), pasando por una máquina con IP pública (horsemen-ui.i3m.upv.es), en un solo comando:

$ ssh ubuntu@10.0.0.29

Para ello hay que tener acceso sin contraseña a horsemen-ui.i3m.upv.es y configurar el archivo .ssh/config que se muestra en el cast. Después podemos utilizar un archivo “.key” como el que se muestra en el cast para acceder a la máquina 10.0.0.29.

Ventajas de este tipo de acceso: además de la comodidad, las claves privadas para el acceso tanto al proxy como al equipo final están en el equipo cliente y no tienen que ser copiadas al proxy.
