Please help! error "/etc/sudoers is mode 0666, should be 0440"

Hi all,

on ubuntu server, I got this message "/etc/sudoers is mode 0666, should be 0440" when I try to do some configurations.

then I got into the recovery mode and put " chmod -R 0440 /etc"
when it boots normally I got ;

(none)login:

when I put any user password it doesnt accept even root user..

what should I do???

thanks in advance!

 

That was a really bad idea! You should have done a

Code:

chmod 0440 /etc/sudoers

but you chmod'ed all files and directories in /etc to 0440 recursively.
I think all you can do is a clean re-install (unless you have a backup of a working /etc directory).

 

thank you for helping..

if I put ubuntu live cd and boot from it and then mount my hard drive to other location..

would it work?

 

as long as you can mount the hard drive
and it should work
