- Para instalar la utilidad en los equipos ControlId

Copiar *+ethtool.tar.gz+* al directorio /tmp
Montar el raíz en lectura escritura: rw
cd / ; tar zxvf /tmp/ethtool.tar.gz

Si el equipo en que se quiere instalar el ethtool tiene problemas de red y pierde paquetes, se puede intentar pasar el ethtool al equipo dividido en ficheros de 1KB. Mirar el siguiente enlace:
*ethtool split*

- Para ver la configuración actual del interfaz eth0:

ethtool eth0

- Para modificar la configuración del interfaz eth0 a una velocidad de 10 Mbps half duplex

ethtool -s eth0 speed 10 duplex half autoneg off

- Para que el interfaz eth0 autonegocie la velocidad y duplex

ethtool -s autoneg on

- Todas las opciones posibles:
