[Snort-devel] Dynamic Preprocessor Example doesn't log in Database

Hi,

My .rules and my Dynamic preprocessor are well loaded, because they both 
logged in the syslog. 
My path for Dynamic Preprocessor is well set: 
dynamicpreprocessor directory 
/usr/local/snort/lib/snort_dynamicpreprocessor/ 
My .rules are in the directory : /usr/local/snort/etc/rules. 
/usr/local/snort/etc is the default directory, so I put: var RULE_PATH 
rules.

For my tests, I used only one rule file which is : include 
$RULE_PATH/local.rules . It's why this is the only one uncommented.
Moreover, I used only one personal Dynamic Preprocessor: preprocessor 
dynamic_example: port 11123 .
I added the compilation of the Dynamic Preprocessor Example into the 
existing Makefile of the Snort 2.9.0.3 project. It's well compiling and 
it's well logging is syslog when the port 11123 is matched.

Do you have any idea of "why only my classic rule ($RULE_PATH/local.rules 
)  can logged is the mysql database and not the dynamic_example" ?

Thank you for your help.

Best regards,

Thomas, 

A couple of things caught my eye:
Your values for SO_RULE_PATH and PREPROC_RULE_PATH do not appear to be 
changed from the defaults, but you have changed your RULE_PATH.
# 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 rules 
var SO_RULE_PATH ../so_rules 
var PREPROC_RULE_PATH ../preproc_rules 

All your preprocessor rules appear to be commented out.

# Step #8: Customize your preprocessor and decoder alerts 
# For more information, see README.decoder_preproc_rules 
################################################### 

# decoder and preprocessor event rules 
# include $PREPROC_RULE_PATH/preprocessor.rules 
# include $PREPROC_RULE_PATH/decoder.rules 
# include $PREPROC_RULE_PATH/sensitive-data.rules 

Neither of these are likely to be the source of problems with your Dynamic 
preprocessors, which if I understood correctly, are generating alerts in 
syslog. 

Can I ask how you configured your dynamicpreprocessors? Did you copy the 
precompiled rules or compile them yourself?

Last, you are using the alert_fast section of barnyard2.conf to stream 
alerts to the screen. Are the dynamicprecprocessor alerts showing up 
there?

Thanks,

Nick

BARNYARD2.CONF: 


#------------------------------------------------------------- 
#  Barnyard2 configuration file 
# 
#  http://www.securixlive.com/barnyard2 
#   
#  Contact: dev at ...3030... 
#------------------------------------------------------------- 

# 
# 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:            /usr/local/snort/etc/reference.config 
config classification_file: /usr/local/snort/etc/classification.config 
config gen_file:            /usr/local/snort/etc/gen-msg.map 
config sid_file:                /usr/local/snort/etc/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 hostname:        localhost 
#config interface:        eth0 
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

Re: [Snort-devel] Dynamic Preprocessor Example doesn't log in Database








Thomas,  

Can you provide a copy of your snort.conf and barnyard.conf files?  

Thanks! 

Nick

Hello, 

I am using Snort 2.9.0.3 in a Debian. 

I can log in database thanks to the snort's classic rule system, like does 
my "test.rules" file contains a rule alerting when the port 200 is used in 
the network. So my Mysql database works and my snort.conf and 
barnyard2.conf seems to be well configured. 

I installed and compiled the Dynamic Preprocessor Example of Snort. It 
works well, and I can see logs in the syslog file when the Dynamic 
Preprocessor Example matches the port I configured in snorf.conf (11123). 

My problem is:  Only the dynamic preprocessor example doesn't log in Mysql 
database (It just logs in the syslog). The example use the 
"_dpd.addAlert(.......);  " function, but it seems it doesn't work for 
me... 

Could you help me please? 

Thank you. 

PS: I tested with another dynamic prepreocessor, it doesn't log in 
database neither.
