Remote login user characteristics

[Marco Santerre]

HI everyone,

I've been doing some searches and found a couple of threads similar to this one :
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=469590

but unfortunately, I was looking more for somehting that equates to the "REMOTE LOGIN ALLOWED" characteristic on AIX.

Does anyone know if that is AIX specific.. or is there a file somewhere that could contain this security feature?

Thanks

Marco

If you can explain us what exactly your "REMOTE LOGIN ALLOWED" achieves in AIX, I am sure forum folks can come up with good suggestions :-)

I apologize for not explaining..

The remote login characteristic in AIX basically stops someone from logging in using that User ID from anywhere remote (rsh, telnet, etc.. ) but doesn't stop it from local (ex. console, and applications using that User ID)

As I mentionned I followed a couple of threads that discussed forcing su for generic IDs.. and it goes along that line but, in AIX, they get that with a User characteristic.. was wondring if the same thing can be found on HP-UX..

For root, you have /etc/securetty file that you can use to restrict the terminals from which root is allowed to login.

But for other normal users, there is no direct straight-forward way to achieve this.

You might have to do little scripting.

You can try somehting like this

# vi /etc/profile
..
..
grep -q "^$LOGNAME" /etc/RES_USRS > /dev/null 2>&1
if [ $? -eq 0 ]
then
grep "^$LOGNAME" /etc/RES_USRS | grep -q `tty` >/dev/null 2>&1
if [ $? -ne 0 ]
then
echo "User $LOGNAME is not allowed to login from Terminal: `tty`"
exit 1
fi
fi

#

# vi /etc/RES_USRS
user1 /dev/console /dev/term01 /dev/term02
user2 /dev/console
user3 /dev/term03
..
..
#

But note, if the user's login shell is CSH, /etc/profile wont be executed and thus the user can remote login to the system.
