A few hours earlier I bought a beaglebone and now I am trying to add nameserver 8.8.8.8
to /etc/resolv.conf
. However when I open it with vim and try to add my nameserver, it gives me E21: cannot make changes, 'modifiable' is off. I changed permissions via chmod. chmod u+rx /etc/resolv.conf
But nothing changed. I am still unable to write into resolv.conf file. What should I do?
