Hi,

I'm using Mac 10.6.3. I'm logged in as the "davea" user who has sudo
privileges. However, I have corrupted my /etc/sudoers file and
accidentally given it 710 permissions. I'm trying to change it back
to 440, but I repeatedly get

davea-mbp2:apache2 davea$ sudo chmod 440 /etc/sudoers
sudo: /etc/sudoers is mode 0710, should be 0440
Segmentation fault

Any ideas how to restore the perms? Thanks, - Dave

Here is what I have:

bash-3.2$ ls -l /etc/sudoers
-r--r----- 1 root wheel 1242 Jun 23 2009 /etc/sudoers


You could enable the root account, xterm -e login & to get a new
window and login as root, at which point, you should be able to chmod it.

To enable root at 10.6:

system->library->core services->directory utility

Click on the lock to authenticate. then select "Local". Then, in the
EDIT menu, you will have options to enable the root account and/or
chsnge its passowrd. You can disable it there once you are done.

In the second option you mention, how do I access "System" (as in
system->Library->...) ? - Dave

Boot into single-user mode, by pressing Cmd-S when you reboot. You have
root permissions then, so you can just use chmod.

In your boot drive, you should have a "System" folder.
