Can't use "su"

juno · 12-26-2002, 11:54 PM

In our system, part of Login ID can't run ¡§su¡¨ to login as other user

eg.
# su - tommy
Password:
su: incorrect password

After I use ¡§su¡¨ and userid , it will pop up ¡§incorrect password¡¨ , someone can suggest how to fix it? Thx.

check the permissions on su.

su needs to be setuid. chmod u+s /path/to/su.

Now the mode is

/bin> ll su
-rwsr-sr-x 1 root EDP 18452 Sep 24 2001 su

but still can't run "su" , do you have other solution? thx.

In Gentoo you need to make the user that you want to use su a member of the wheel group. Try that!

Um.. silly question perhaps but..

you can login as tommy from a login prompt, right?
