Hi,

enable direct root login only from console

# echo console > /etc/securetty

setup a SU_ROOT_GROUP=XXXX in the /etc/default/security

create a blank file in /etc directory name securtty. This will stop direct root user login to system even on console. If you want root to login directly on console then enter"console" in this file.

Hi,

Disable telnet or disable root login??

root login

cat console > /etc/securetty
chmod 440 /etc/securetty

(root login only through console)

Disable telnet.
hash the entries for telnet in /etc/inetd.conf and restart the inetd service. You may have to install ssh to login to the server, once you disable telnet.
