# Fail2Ban configuration file
|
|
#
|
|
# 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)
