- 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:
