fedora 7 fürs inet abhärten?

[le bart]

gut, fail2ban läuft (dank yum sofort) aber er lässt mich auch nach x fehlversuchen noch ran... was könnt da falsch laufen? im jails.conf hab ich schon bei der iptables-action den port von ssh auf den port gestellt auf dem bei mir ssh läuft.

hier mal der output von iptables -save zur allgemeinen analyse ob eh nur ssh offen is, thx!:
