#
# Author: Russell Odom <russ@gloomytrousers.co.uk>
# Submits attack reports to myNetWatchman (http://www.mynetwatchman.com/)
#
# You MUST configure at least:
# <port> (the port that's being attacked - use number not name).
# <mnwlogin> (your mNW login).
# <mnwpass> (your mNW password).
#
# You SHOULD also provide:
# <myip> (your public IP address, if it's not the address of eth0)
# <protocol> (the protocol in use - defaults to tcp)
#
# Best practice is to provide <port> and <protocol> in jail.conf like this:
# action = mynetwatchman[port=1234,protocol=udp]
#
# ...and create "mynetwatchman.local" with contents something like this:
# [Init]
# mnwlogin = me@example.com
# mnwpass = SECRET
# myip = 10.0.0.1
#
# Another useful configuration value is <getcmd>, if you don't have wget
# installed (an example config for curl is given below)

#
# Note: We are currently using <time> for the timestamp because no tag is
# available to indicate the timestamp of the log message(s) which triggered the
# ban. Therefore the timestamps we are using in the report, whilst often only a
# few seconds out, are incorrect. See
