Description Ted Knupke 1999-12-02 18:05:59 UTC 
It is possible for a remote user to log into root via su even when
/etc/security/access.conf is set up to deny access to root from remote
locations.  (I am not sure whether this is a problem with su or with pam.)
Comment 1 Elliot Lee 2000-02-03 18:40:59 UTC 
This is the normal, expected behaviour. If you wish to deny root shells at all
from remote hosts, you can change your PAM configuration to use the
pam_securetty module for the 'su' service.
