Hi All,

I was running '# ls -l' in '/' directory and I noticed all directories in '/' have the following permeation 'drwxr-xr-x' [except root's home which is 'drwx------' (after I change it from 'drwxr-xr-x' )]

I don't want all the user (except root) to be able to read and execute (in) any directory, I just want every user to be abel to read/write/execute only in his/her home directory.

my question is, is it ok to change file and directory permeation of the following directories in '/' from 'drwxr-xr-x' to 'drwxr-x---' or 'drwx------' recursively?

/bin
/boot
/dev
/etc
/home
/lib
/proc
/sbin
/sys
/tmp
/usr
/var

Will it effect application, (like clamav) or will it effect users been able to do day to day things?

os = Zenwalk 6.0 stock
K = 2.6.28.7 (stock from Zenwalk 6.0)
-I and the other users use the pc for internet, open office and email mainly.
-It does not run server(s) like smb/cif or NFS.
-There are 5 usernames (created by me, non of them are superusers) in th pc, only one user is required to login at any one time.


Thankyou all for your time.

Hi,

all standard linux commands, such as cat, bash, ls ... are in /bin.
If you remove execution permission to that directory, users will
not be able to do anything :-(

I'd let the permission in default setting.

The word is permission.

You **can** change the permissions as you suggest, but--as stated above--I don't think you really **want** to.

Look at the man pages for "chmod", including the -R flag

I'd also question why you think you need to? Is it just that you are doing the old trick of "if I disable everything then it will all be ok"?? Do you have any specific reason as to why you want to do this? Is there something you see as a security risk?
