+# Notes.:  regex to match the password failures messages in the logfile. The
+#          host must be matched by a group named "host". The tag "<HOST>" can
+#          be used for standard IP/hostname matching and is only an alias for
+#          (?:::f{4,6}:)?(?P<host>\S+)
+# Values:  TEXT
+
+# These match the unmodified dropbear messages. It isn't possible to
+# match the source of the 'exit before auth' messages from dropbear.

+# NOTE: The failregex below is ONLY intended to work with a patched
+# version of Dropbear as described here:

+# The standard Dropbear output doesn't provide enough information to
+# ban all types of attack.  The Dropbear patch adds IP address
+# information to the 'exit before auth' message which is always
+# produced for any form of non-successful login. It is that message
+# which this file matches.
