Comments: use '#' for comment lines and ';' (following a space) for inline comments
 The DEFAULT allows a global definition of the options. They can be overridden
 in each jail afterwards.
 [DEFAULT]
 "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fail2ban will not
 ban a host which matches an address in this list. Several addresses can be
 defined using space separator.
 ignoreip = 127.0.0.1/8
 External command that will take an tagged arguments to ignore, e.g. ,
 and return true if the IP is to be ignored. False otherwise.
 #
 ignorecommand = /path/to/command 
 ignorecommand =
 "bantime" is the number of seconds that a host is banned.
 bantime  = 600
 A host is banned if it has generated "maxretry" during the last "findtime"
 seconds.
 findtime  = 600
 "maxretry" is the number of failures before a host get banned.
 maxretry = 3
 "backend" specifies the backend used to get files modification.
 Available options are "pyinotify", "gamin", "polling" and "auto".
 This option can be overridden in each jail as well.
 #
 pyinotify: requires pyinotify (a file alteration monitor) to be installed.
 If pyinotify is not installed, Fail2ban will use auto.
 gamin:     requires Gamin (a file alteration monitor) to be installed.
 If Gamin is not installed, Fail2ban will use auto.
 polling:   uses a polling algorithm which does not require external libraries.
 auto:      will try to use the following backends, in order:
 pyinotify, gamin, polling.
 backend = auto
 "usedns" specifies if jails should trust hostnames in logs,
 warn when DNS lookups are performed, or ignore all hostnames in logs
 #
 yes:   if a hostname is encountered, a DNS lookup will be performed.
 warn:  if a hostname is encountered, a DNS lookup will be performed,
 but it will be logged as a warning.
 no:    if a hostname is encountered, will not be used for banning,
 but it will be logged as info.
 usedns = warn
 This jail corresponds to the standard configuration in Fail2ban.
 The mail-whois action send a notification e-mail with a whois request
 in the body.

 !!! WARNING !!!
 Since UDP is connection-less protocol, spoofing of IP and imitation
 of illegal actions is way too simple.  Thus enabling of this filter
 might provide an easy way for implementing a DoS against a chosen
 victim. See
