How to Save Failed Login Attempts

1. Become superuser or assume an equivalent role.

2. Create the loginlog file in the /var/adm directory.

   # touch /var/adm/loginlog

3. Set read and write permissions for root on the loginlog file.

   # chmod 600 /var/adm/loginlog

4. Change group membership to sys on the loginlog file.

   # chgrp sys /var/adm/loginlog

5. Make sure that the log works by attempting to log into the system five times with the wrong password. Then, display the /var/adm/loginlog file.
