fail2ban binary package in Ubuntu Trusty powerpc

 Fail2ban monitors log files (e.g. /var/log/auth.log,
 /var/log/apache/access.log) and temporarily or persistently bans
 failure-prone addresses by updating existing firewall rules. Fail2ban allows
 easy specification of different actions to be taken such as to ban an
 IP using iptables or hostsdeny rules, or simply to send a
 notification email.
 .
 By default, it comes with filter expressions for various services
 (sshd, apache, qmail, proftpd, sasl etc.) but configuration can be
 easily extended for monitoring any other text file. All filters and
 actions are given in the config files, thus fail2ban can be adopted
 to be used with a variety of files and firewalls.
