You can determine current connections with "w" or "who". The "last" command will give a history of connections and the length of the connection.

Try

Code:

skill -KILL -u $username

EDIT: That will only "logout" the offending user if they're logged in. If you want to block their access you'll want to put their IP address into /etc/hosts.deny and maybe change some passwords

If the user is logging in locally then you need better security.
