If fail2ban is # configured to run as root, firewall setup can be performed by # fail2ban automatically. However, if fail2ban is configured to run as # a normal user, the configuration must be done by some other means # (e.g. using static firewall configuration with the # iptables-persistent package). # # Explanation of the rule below: # Check if any packets coming from an IP on the <iptname> # list have been seen in the last 3600 seconds. If yes, update the # timestamp for this IP and drop the packet. If not, let the packet # through. # # Fail2ban inserts blacklisted hosts into the <iptname> list # and removes them from the list after some time, according to its # own rules. The 3600 second timeout is independent and acts as a # safeguard in case the fail2ban process dies unexpectedly. The # shorter of the two timeouts actually matters. actionstart = if [ `id -u` -eq 0 ];then <iptables> -I <chain> -m recent --update --seconds 3600 --name <iptname> -j <blocktype>;fi # Option: actionflush # # [TODO] Flushing is currently not implemented for xt_recent # actionflush = # Option: actionstop # Notes.: command executed at the stop of jail (or at the end of Fail2Ban) # Values: CMD # actionstop = echo / > /proc/net/xt_recent/<iptname> if [ `id -u` -eq 0 ];then <iptables> -D <chain> -m recent --update --seconds 3600 --name <iptname> -j <blocktype>;fi # Option: actioncheck # Notes.: command executed once before each actionban command # Values: CMD # actioncheck = test -e /proc/net/xt_recent/<iptname> # Option: actionban # Notes.: command executed when banning an IP.
