hi,

Create a file security in /etc/default and Put NOLOGIN=1 File owner will be root with 644 permissions. Also create a file in /etc/nologin and Put the message in there so that users gets it.

or aditional option :

For older versions of HPUX, you can add this bit of logic to the /etc/profile. Then "touch /etc/nologin"



for the /etc/profile to prevent user logins during system maintenance while
in multiple mode:

if [ -f /etc/nologin ]
then
if [ $LOGNAME != "root" ]
then
echo "System maintenance is be performed and users are being"
echo "prevented from accessing the system."
sleep 5
exit
fi
fi

To prevent Direct Login to specific ids, Add them in /etc/no_login_allowed.
