I have changed your script like that:
Add this to .profile
ALLOWEDLOGINCOUNT=1
if test "$LOGNAME" != "root"
then
CURRENTLOGINCOUNT=`who | grep ${LOGNAME} |wc -l`
echo CURRENT logged in user including this session:
${CURRENTLOGINCOUNT}
echo ALLOWED login count: ${ALLOWEDLO
The method we use is to add some "special sauce" to the users .profile file.
The following code works for ksh:
if test "$LOGNAME" != "special"
then
set -- `who | grep -v "\`who am i\`" | grep "^$LOG "`
[ -n "$*" ] && abort "$1 is already logged on at $2"
fi
where "special" is the name of a user

Hi,
Is it possible to limit users to login just one at a time?
I mean user X can login from anywhere (ssh,telnet,X) but when he is logged
in any other attempt to login with the username X is prohibited and maybe
printed out a message like "This user is already logged in"?
Best Regards.
