# Configuration:
# Set the following Domino Server parameters in notes.ini:
# console_log_enabled=1
# log_sessions=2
# You also have to use a date and time format supported by fail2ban. Recommended notes.ini configuration is:
# DateOrder=DMY
# DateSeparator=-
# ClockType=24_Hour
# TimeSeparator=:
#
# Depending on your locale you might have to tweak the date and time format so fail2ban can read the log

# Read common prefixes. If any customizations available -- read them from
# common.local
#before = common.conf

# Option: failregex
# Notes.: regex to match the password failure messages in the logfile. The
# host must be matched by a group named "host". The tag "
" can
# be used for standard IP/hostname matching and is only an alias for
# (?:::f{4,6}:)?(?P\S+)
# Values: TEXT
#
# Sample log entries (used different time formats and an extra sample with process info in front of date)
