I had already Fail2ban installed a long time ago. Attack-detector app installed with no problem on 7.2 Home. All is working correctly except one thing: in the log, i've a lot of banned IP exceeding my ban limit (86400s = one day). After looking in the code of this app, it seems that the IP showing in the log are grepped on fail2ban.log only for the word 'BAN' so the IP UNBANed are not deleted.
I know it's only 'cosmetic' as fail2ban is working correcly, it unbans those IP after the limit.
Clearos please continue your excellent work.
Sorry for my english (I'm French and a long time user of your distribution (I think, I began with COS 3; was a long time ago ;-))
