Reinstall Linino

Hi,

How can I reinstall Linino in Arduino Yun, I forgot the password and I can´t configure the board.

You could reset root password, use USB upload YunSerialTerminal, get console then type passwd.

But with that get that resume at baseline?, Such as IP addresses or names tables ...

Hold down the reset next to the USB host connector for 30 seconds. That will reset your Yún back to base configuration. Note that it will wipe out any files you've put on the Linux side (except for anything on the SD card)
