Restricting Multiple loggin sessions
Any idea as to how multiple loggin sessions by the same user (using Hyper terminal/Telnet) be restricted in Sun Solaris 8.

you can add the following to the users profile :

USERLOGINS=`who | grep ( userid ) | wc -l`
if [ "$USERLOGINS" -eq ( max no. of logins ) ] ; then
exit 1
else
( process remaining environment )
fi

If we are strict at "restrict", there should be better approach. Is there PAM for Solaris?

Pluggable Authentication Modules and no it's not there in Solaris 8 by default.

Add this to the global profile (/etc/profile or whatever) otherwise the user will just login, vi $HOME/.profile, and remove it....

Code:
MAXLOGINS=5   # or whatever
WHOAMI=`whoami`
CURRENTLOGINS=`who | grep -c "${WHOAMI}"`
if [ "${CURRENTLOGINS}" -eq "${MAXLOGINS}" ]; then
  exit 1
fi
# no need for else.... rest of profile goes here

Cheers
