Nipe
An engine to make Tor network your default gateway
Nipe is a Perl-based engine whose primary aim is to make the Tor network act as the default gateway for outgoing traffic. In practice, it configures system firewall rules (iptables) and network routing so that almost all IPv4 traffic is redirected through Tor. The tool provides commands such as install, start, stop, restart, and status to manage its behavior. When “start” is issued, it sets up the necessary rules; when “stop” is used, it attempts to remove those rules. Nipe currently operates over IPv4 and does not yet support IPv6, meaning that users with IPv6 connectivity may bypass Tor routing. ... -

Fail2Ban
Daemon to ban hosts that cause multiple authentication errors
Fail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. sending an email) could also be configured. Out of the box Fail2Ban comes with filters for various services (apache, courier, ssh, etc). Fail2Ban is able to reduce the rate of... -
