In order to find out if someone logged in, I should then first copy
auth.log to auth2.log, and do a compare and then do the tail trick. Have
to cron that every half a minute.
I would like to know if there is something that is alterted on the
moment that someone logs on thus forcing evt. your tail suggestion
