Root access

[Paul T. Cardullo_1]

How do you block root from remote access? restrict him to console only

[Helen French]

You can do it by creating a file /etc/securetty. Add console in the file and then you will be able to access root only from console.

# man login (for more details)

Hi Paul,

Do the following

echo console > /etc/securetty
chmod 400 /etc/securetty
chown root:sys /etc/securetty

That'll do it.

HTH,

You can (and should) also restrict the list of users allowed to su to root

configure /etc/default/security
SU_ROOT_GROUP=
