I want to change the network mask for eth0.
When I do the ifconfig eth0 126.96.36.199 netmask 255.255.255.0 (what I need it to be) I get Operation not permitted.
So I try and change to super user with the su command.
su fails with authentication failure
Tried astroberry and raspberry as passwords, no luck.
Looked at the document on astroberry.io it was not any help.
Does anyone know the su passwrod for astroberry?
