i was wondering if there is a simple way and/or a package that i can use on my router to log "hack attempts" to my linux router, so i can see if anyone's trying to DDoS me or something.

just something simple so i can see whats goin on (like HackerTracer or BlackICE for instance)

cheers

go to linux program pages, like tucows, youll find something there

If you have logging enabled in your firewall ruleset, you could just do a 'tail /var/log/messages'

Kinda crude

otherwise, look on freshmeat. Do a search for filewall log parsers or something.
