#
# This file contains a sample barnyard2 configuration. 
# You can take the following steps to create your own custom configuration:
#
#   1) Configure the variable declarations
#   2) Setup the input plugins
#   3) Setup the output plugins
#

# Step 1: configure the variable declarations
#
# in order to keep from having a commandline that uses every letter in the
# alphabet most configuration options are set here.

# use UTC for timestamps
#
#config utc

# set the appropriate paths to the file(s) your Snort process is using.
#
config reference_file:	    /etc/snort/reference.config
config classification_file: /etc/snort/classification.config
config gen_file:            /etc/snort/gen-msg.map
config sid_file:	        /etc/snort/sid-msg.map

# define dedicated references similar to that of snort.
#
#config reference: mybugs http://www.mybugs.com/?s=

# define explicit classifications similar to that of snort.
#
#config classification: shortname, short description, priority

# set the directory for any output logging
#
#config logdir: /tmp

# to ensure that any plugins requiring some level of uniqueness in their output
# the alert_with_interface_name, interface and hostname directives are provided.
# An example of usage would be to configure them to the values of the associated
# snort process whose unified files you are reading.
#
# Example:
#   For a snort process as follows:
#     snort -i eth0 -c /etc/snort.conf
#
#   Typical options would be:
#     config hostname:	thor
#     config interface: eth0
#     config alert_with_interface_name
#
#config hostname:	thor
#config interface:	eth0

# enable printing of the interface name when alerting.
#
#config alert_with_interface_name

# at times snort will alert on a packet within a stream and dump that stream to
# the unified output. barnyard2 can generate output on each packet of that 
# stream or the first packet only.
#
#config alert_on_each_packet_in_stream

# enable daemon mode
#
#config daemon

# make barnyard2 process chroot to directory after initialisation.
#
#config chroot: /var/spool/barnyard2

# specifiy the group or GID for barnyard2 to run as after initialisation.
#
#config set_gid: 999

# specifiy the user or UID for barnyard2 to run as after initialisation.
#
#config set_uid: 999

# specify the directory for the barnyard2 PID file.
#
#config pidpath: /var/run/by2.pid

# enable decoding of the data link (or second level headers).
#
#config decode_data_link

# dump the application data
#
#config dump_payload

# dump the application data as chars only
#
#config dump_chars_only

# enable verbose dumping of payload information in log style output plugins.
#
#config dump_payload_verbose

# enable obfuscation of logged IP addresses.
#
#config obfuscate

# enable the year being shown in timestamps
#
#config show_year

# set the umask for all files created by the barnyard2 process (eg. log files).
#
#config umask: 066

# enable verbose logging
#
#config verbose

# quiet down some of the output
#
#config quiet

# define the full waldo filepath.
#
#config waldo_file: /tmp/waldo

# specificy the maximum length of the MPLS label chain
#
#config max_mpls_labelchain_len: 64

# specify the protocol (ie ipv4, ipv6, ethernet) that is encapsulated by MPLS.
#
#config mpls_payload_type: ipv4

# set the reference network or homenet which is predominantly used by the
# log_ascii plugin.
#
#config reference_net: 192.168.0.0/24

#
# CONTINOUS MODE 
#

# set the archive directory for use with continous mode
#
#config archivedir: /tmp

# when in operating in continous mode, only process new records and ignore any
# existing unified files
#
#config process_new_records_only



# Step 2: setup the input plugins
#
# this is not hard, only unified2 is supported ;)
input unified2



# Step 3: setup the output plugins

# alert_cef
#-----------------------------
#
# Purpose:
#  This output module provides the abilty to output alert information to a
# remote network host as well as the local host using the open standard
# Common Event Format (CEF).
#
# Arguments: host=hostname[:port], severity facility
#            arguments should be comma delimited.
#   host		- specify a remote hostname or IP with optional port number
#                 this is only specific to WIN32 (and is not yet fully supported)
#	severity	- as defined in RFC 3164 (eg. LOG_WARN, LOG_INFO)
#	facility	- as defined in RFC 3164 (eg. LOG_AUTH, LOG_LOCAL0)
#
# Examples:
#	output alert_cef
#	output alert_cef: host=192.168.10.1
#	output alert_cef: host=sysserver.com:1001
#	output alert_cef: LOG_AUTH LOG_INFO
#
