+# Fail2Ban configuration file
+#
+# Author: Russell Odom <russ@gloomytrousers.co.uk>
+# Submits attack reports to DShield (http://www.dshield.org/)
+#
+# You MUST configure at least:
+# <port> (the port that's being attacked - use number not name).
+#
+# You SHOULD also provide:
+# <myip> (your public IP address, if it's not the address of eth0)
+# <userid> (your DShield userID, if you have one - recommended, but reports will
+# be used anonymously if not)
+# <protocol> (the protocol in use - defaults to tcp)
+#
+# Best practice is to provide <port> and <protocol> in jail.conf like this:
+# action = dshield[port=1234,protocol=tcp]
+#
+# ...and create "dshield.local" with contents something like this:
+# [Init]
+# myip = 10.0.0.1
+# userid = 12345
+#
+# Other useful configuration values are <mailargs> (you can use for specifying
+# a different sender address for the report e-mails, which should match what is
+# configured at DShield), and <lines>/<minreportinterval>/<maxbufferage> (to
+# configure how often the buffer is flushed).
