permission denied on everything involving su and sudo.
Im using fedora 10 on a g4 mac. Im having some very frustrating problems.
1st- i can no longer use the command "su" when i try it ask for my password i enter it correctly and then it says /var/log: permission denied.
Something goes when i enter "gpasswd" or even try to enter chmod command to change permission.
2nd- i can't use sudo because i cant add my username funkymonkey to sudoers because when i try i get to add it i get denied permission. Ive tried everything i can think of. Im still fairly new to this so i tried everything ive learned so far. So can aybody with so experience please help me
