You'll have to, one-by-one, change the permissions back to what they need to be.

If you post the output of:

ls -ald /*

one of us can probably help you.

output of ls -ald /* is this:


[root@server1 /]# ls -ald /*

[gokhanweb]

[jlasman]

I can only give you permissions for what I've got.

Here's the list from one of my DA servers running on CentOS 3:
[jlasman@host /]$ ls -ald *

-rw------- 1 root root 10240 Oct 30 05:05 aquota.user

drwxr-xr-x 22 root root 118784 Sep 1 00:52 dev
drwxr-xr-x 48 root root 4096 Nov 2 00:11 etc

drwxr-xr-x 20 root root 4096 Jul 9 2004 var
[jlasman@host /]$
These should work for you. I don't know about the other directories, since I don't have them on the server I'm checking.
