Хочу ограничить скорость подключения со 100 до 10.
при вводе команды c параметром autoneg off
# ethtool -s eth0 speed 10 duplex full autoneg off
Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autonegЕсли параметр убрать, то настройки скорости не меняются.
Если изменить на autoneg on то пропадает соединение, а ethtool eth0 выдает
Settings for eth0:
