Chmod + Newbie = #@!$

okay Im a complete noob to linux

I accidentally did:
chmod 750 /

then in a newbie panic I closed the shell... after failing to change back to super user I decided I might log out and log back in a root...

Am I going to have to reinstall, or is there a way to get back into root so I can fix this?

If there is, whats the default permissions for the root dir /?

default root permission is 750 only

Actually, the default permission for / is 755. 750 would effectively block normal users from using the system, as they are not allowed to use any file or directory on the system.

(if I understand things correctly, that is :-)

Groetjes,

Just use chmod to change them back.

/tmp -> 1777
/root -> 710
everything else -> 755

if you don't understand how the file permissions work, this will help a lot.
