I think I should change the option rotate in /etc/logrotate.conf

...
/var/log/wtmp {
    missingok
    monthly
    create 0664 root utmp
    rotate 1 <------ change this value to 12 to keep log files for 12
months
}
...

But I have another doubt. This log only the login at this machine. But
how to log the autentication of other machines at the NIS server?

How keep the login history of NIS clients at only one file at NIS
server?

Is there any way to do that?

My idea is to use this strategy as a alternative to generate an
attendance list of students in classroom.
