Edit file File name : route.conf Content :# Fail2Ban configuration file # # Author: Michael Gebetsroither # # This is for blocking whole hosts through blackhole routes. # # PRO: # - Works on all kernel versions and as no compatibility problems (back to debian lenny and WAY further). # - It's FAST for very large numbers of blocked ips. # - It's FAST because it Blocks traffic before it enters common iptables chains used for filtering. # - It's per host, ideal as action against ssh password bruteforcing to block further attack attempts. # - No additional software required beside iproute/iproute2 # # CON: # - Blocking is per IP and NOT per service, but ideal as action against ssh password bruteforcing hosts [Definition] actionban = ip route add <blocktype> <ip> actionunban = ip route del <blocktype> <ip> actioncheck = actionstart = actionstop = [Init] # Option: blocktype # Note: Type can be blackhole, unreachable and prohibit. Unreachable and prohibit correspond to the ICMP reject messages. # Values: STRING blocktype = unreachable Save
