Hi,
i did a great mistake.
i wrote chmod 755 /* .
after i wrote chmod 777 /tmp .
but i am in the a great security risk.
what can i do.

thanks.
 
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:

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

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:

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.
