Restricting the number of login sessions of a user

If you wish to restrict the maximum number of login sessions for a specific user, you can do this by modifying the .profile of that user:

A=`w| grep $LOGNAME | wc -l`
if [ $A -ge 3 ] ; then
  exit
fi
This example restricts the number of logins to three. Make sure the user can't modify his/her own .profile by restricting access rights.

UNIX Health Check is an automated check list. It will report on perfomance, capacity, stability and security issues. It will alert on configurations that can be improved per best practices, or items that should be improved per audit guidelines. A report will be generated in the format you wish, and the report includes the issues discovered and information on how to solve the issues as well.
