/bin/su


Hello ..
after upgradeing from kde(RedHat~9) to kde(fedora)
/bin/su wont work correctly when switching from a
user to the root...
so i #chmod 0641 /bin/su it worked just the first step
but wont accept the password at all (i'm writeing it correct)
anyOne has an idea???..
thanks
i changed to 0641 because it keeps saying permission denied when i'm trying su - ..So when i changed it giveing the user X permission it execute the program but keep saying password incorrect i also changed the proG
to 0755 before i post the question ..the same

This is very odd, you shouldn't need to change /bin/su permissions. Also, 0641 is wrong, you are setting permissions to:

rw-r----x

This would basically turn any file 'unexecutable' (owner can read/write, group can read and olny others can execute -- but not read, which ends up turning executable flag useless).

The right permissions should be 4755:

~ ls -l /bin/su
-rwsr-xr-x 1 root root 95957 Mar 3 12:47 /bin/su*

Please note the extra '4': it means you're turning set user ID on.
