Sudo Problem
 

I typed:

sudo
sudo: /etc/sudoers is mode 0440, should be 0640

then from root:

chmod 640 /etc/sudoers
sudo

>>> sudoers file: syntax error, line 34 <<<
>>> sudoers file: syntax error, line 35 <<<
>>> sudoers file: syntax error, line 36 <<<
sudo: parse error in /etc/sudoers near line 34

Any idea?

Without knowing the contents of your sudoers file (especially lines 34-36), it is hard to tell you. Have you been using visudo to edit sudoers? It is supposed to check syntax for you when you finish editing.

Thanks,

SMB4K had written some lines in sudoers without me knowing... I removed those lines and it works fine...
