|
|
# Changing iptables rules requires root privileges. 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.
