There are 2 sets of events being sent, auth/acct/session open/close are from 
pam. But cron sends the same events. So, sshd itself sends another event 
USER_LOGIN that is to signify that the pam events are associated with a login 
and what the final result were.

I guess Gentoo is unpatched. Things will not work right without that last 
patch. All analysis software is predicated on seeing that event.

You only have to set its tcp_listen_port to the same one that M1 & M2 are 
trying to connect on, update tcp_wrappers hosts.allow file to allow M1 & M2 to 
connect, then if you have selinux, you need to tell it what port you are 
using, and you also need to punch a hole in your firewall for that port.

This looks fine. It should be working for you, then.
