Hello There,
Please help with this. I been working very hard to sort out this since a week. but still no success.
Note: all the directories are correctly matched with my installation if this work then by barnyard2 will write the data to DB (pulledpork & barnyard2 are perfectly working)
Snort command: 1. snort -A fast -d -D -k none -i eth0 -u snort -g snort -l /var/log/snort
- snort -q -c /etc/snort/snort.conf -u snort -p snort -l /var/log/snort -k none
- and other command which are available onlne
Thanks in abvance Cheers Rishi

Hello There,
Please help with this. I been working very hard to sort out this since a week. but still no success.
Note: all the directories are correctly matched with my installation if this work then by barnyard2 will write the data to DB (pulledpork & barnyard2 are perfectly working)
Snort command: 1. snort -A fast -d -D -k none -i eth0 -u snort -g snort -l /var/log/snort
Thanks in abvance Cheers Rishi

Compatible with Snort Versions:
VERSIONS : 2.9.7.x
Snort build options:
OPTIONS : --enable-gre --enable-mpls --enable-targetbased --enable-ppm --enable-perfprofiling --enable-zlib --enable-active-response --enable-normalizer --enable-reload --enable-react --enable-flexresp3
Additional information:
This configuration file enables active response, to run snort in
test mode -T you are required to supply an interface -i
or test mode will fail to fully validate the configuration and
exit with a FATAL error
--------------------------------------------------
This file contains a sample snort configuration.
You should take the following steps to create your own custom configuration:
1) Set the network variables.
2) Configure the decoder
3) Configure the base detection engine
4) Configure dynamic loaded libraries
5) Configure preprocessors
6) Configure output plugins
7) Customize your rule set
8) Customize preprocessor and decoder rule set
9) Customize shared object rule set
Step #1: Set the network variables. For more information, see README.variables

other variables, these should not be modified
ipvar AIM_SERVERS [64.12.24.0/23,64.12.28.0/23,64.12.161.0/24,64.12.163.0/24,64.12.200.0/24,205.188.3.0/24,205.188.5.0/24,205.188.7.0/24,205.188.9.0/24,205.188.153.0/24,205.188.179.0/24,205.188.248.0/24]
Path to your rules files (this can be a relative path)
Note for Windows users: You are advised to make this an absolute path,
such as: c:\snort\rules
var RULE_PATH /etc/snort/rules var SO_RULE_PATH /etc/snort/so_rules var PREPROC_RULE_PATH /etc/snort/preproc_rules
If you are using reputation preprocessor set these
Currently there is a bug with relative paths, they are relative to where snort is
not relative to snort.conf like the above variables
This is completely inconsistent with how other vars work, BUG 89986
Set the absolute path appropriately
var WHITE_LIST_PATH /etc/snort/rules var BLACK_LIST_PATH /etc/snort/rules
