output of ippl....
- i'd say i have enough info to go chase down unathorized
attempts on different ports
- i can run a cronjob every 5 min to selectively
go and check or ignore it
- you can put this log file outside of /var/log/*
( say we put the ippl log file at /x/y/z/abc/x.log )
- which is why i like it
- and is 1 minute to install/setup..
- i prefer to get raw data... and i'll post process it
with my filters/config options and paranoia level
and cross check against other IDS reports
