scripting help...please

[Peter Gillis]

Hi,..hpux11.11v1, rp2470

My aim is to restrict login via startup script. This is what I have written into the /etc/profile:
if [ -r /etc/maintenance_mode ]
then
if [ $LOGNAME != root ]
echo " System down for maint "
then
exit 1
fi
fi

This is supposed to let only root login, and no other users (when attempting logging in with posix/bourne sh, but this is actually stopping ALL users including root from logging in.
Anyone see where I am going wrong. Help much appreciated and lotsa points floating around.
thanks heaps
Maria

Hi Maria,

Try this,

if [ -f /etc/maintenance_mode ]
then
if [ "$LOGNAME" != "root" ]
echo " System down for maint "
then
exit 1
fi
fi

hope this helps.

You are doing this the hard way. Edit /etc/default/security and add this line:
NOLOGIN=1


Now, when the file /etc/nologin exists only root can login; all other users receive a message from login that they are not allowed to login.

When maintenance mode is finished, simply remove or rename /etc/nologin. You don't need to do any scripting because login will handle it for you.

hi,

Sorry about the previous post.

try this,

if [ -f /etc/maintenance_mode ]
then
if [ "$LOGNAME" != "root" ]
then
echo " System down for maint "
exit 1
fi
fi

Hope this helps.

Your script has an error

if [ $LOGNAME != root ]
echo " System down for maint "
then

You should have this instead-

if [ $LOGNAME != root ]
then
echo " System down for maint "

"then" should be right after the "if"

Thanks all.
I have tested both methods, and they are working for us.
with the /etc/profile script I had to also put the spaces between the [ and " , then all worked ok.
Thanks Clay, for the nologin info - this appears to be the way to go for notifying ( and kicking off) all types of shell users.
