Re: ipfilter rules

Are you referring to the gen_reports -r netprobes report?

Any packet that comes in on an unopened port shows up there, I use it
all the time.

As for denials, you can use "showaudit -ak" for live time reporting
of Denials or "showaudit -a" for listings from the audit file itself.

There is also acat -ae 'type AUDIT_T_ACLDENY" /var/log/audit.raw
