>Description:
Because of the rotation of the log files (/etc/messages) when /etc/security sear
ch for the 'login failure' and 'refused connect', it can miss some of them in th
e compressed files.
If the rotation is slow because of changes in /etc/newsyslog.conf or small numbe
r of events, it reports the same event each day until the rotation is done.
>How-To-Repeat:
Make some login failures and make the /var/log/message rotate.
or
Make a login failure one day and wait for the security report during few days.
>Fix:
Here is a patch I applied to /etc/security :
