I have install Sarge using instructions from http://www.howtoforge.com/perfect_setup_debian_sarge
, everything was great! And when I try to edit file /etc/network/interfaces/, I've get the magic answer: Permission denied! When I try call other files, I haven't other answer. What's this problem? Root have full permissions default, but system say me "get out!" Why?
Serriously, how can I to continue my work?
