bash script to count red hat linux concurrant logins
Our server run red hat Linux AS 5.4 with over 700 users connected. We would like to limit users to 3 concurrent logins. Red hat support has told me there is no built in method for limiting users to 3 concurrent logins.
1. Is Red Hat support correct, is there a way to limit user logins to 3 concurrent logins?
2. Is there a simple way to identify users with multiple concurrent logins?
