permission denied on everything involving su and sudo.
 

. Hi,

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

The password the su command is asking for is the root password, not your password. Each account has its own password.

What command are you typing that gives the error "/var/log: permission denied"?
