Barnyard reading unified files from snort.

Still having issues getting BarnYard to read from snort.  Attached are the barnyard and snort conf.

 

Below is the output from syslog.  I believe that the highlight shows that it is looking in the correct directory, but it doesn’t seem correct that it reads one record, nor that the Waldo is not correct.  The Waldo file is empty -rwxrwxr-x 1 snort snort         0 May  6 12:07 barnyard2.waldo

#  http://www.securixlive.com/barnyard2

#
#  Contact: dev <at> securixlive.com
#-------------------------------------------------------------

#
# 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: snort

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

# 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

Help would be appreciated!

Hi guys,

I've been playing around with Snort for a while now as a little project of mine, and I'm doing my best to get the hang of writing rules for it. I'm becoming more familiar with how signatures are made, and I'd like to begin writing rules which aren't currently detected by Snort, even if they're fairly simple ones.

Currently I'm using Snort as a sniffer on a Kali Linux VM, metasploit on another Kali Linux VM, and Windows 2000 & XP as victim machines. I've been looking for exploits on sites such as exploit db and 1337day, and I'm trying to start with plain text protocols such as FTP and HTTP to make writing the rules slightly easier for me (using basic regular expressions and such).

If anybody could help me out it would be much appreciated, I've been trying to get my head around writing a rule that's not currently detected for a while now, and I'm not having much luck.

I'm not familiar with how these mailing lists work as well, so apologies if this isn't the sort of thing I should be posting - I've looked quite thoroughly for forums dedicated to Snort, and was hoping to find some good ones, especially with sections for beginners, although haven't had any luck as of yet.

Thanks for any help,

Charlie

Only seeing TCP Alerts

Hello All,

 

I have recently gotten Snort 2.9.6.0 installed, along with Barnyard2, Oinkmaster, and BASE as the frontend.

 

When I open the web page on the server for BASE and view the home page I only see, TCP (100%), in the “Traffic Profile by Protocol”. Everything else, is showing 0%.

For example, I see:

            TCP (100%)

UDP (0%)

ICMP (0%)

Portscan Traffic (0%)

 

I’m wondering why ALL the others are at 0%? Over the last 48 hours or so there has to have been some kind of UDP traffic, don’t ya think?

I also attempted to run a portscan (*using “nmap 10.60.114.0/24“) on the whole ipvar configured for HOME_NET. But I don’t think the Portscan part was picked up either…

 

If I check the MySQL database for snort, the “tcphdr” table has tons of data in it, but the “udphdr” table is completely empty. If I run “select * from udphdr”, mysql returns “Empty set (0.00 sec)”. So I’m not sure if I have snort configured correctly or not..?

 

Is there any tests that anyone could suggest to help me figure out why UDP, ICMP and Portscan are not being picked up?

If you need to see my snort.conf, just let me know. If so does the mailing-list take attachments?

 

Any thoughts or suggestions would be much appreciated!

 

Thanks in Advance,

Matt

snort - unified2 formart

I am running the latest version of snort

snort-2.9.6.1-1.x86_64

in /etc/snort/snort.conf


I added this and commented out the other lines:

output unified2: filename snort.u2, limit 128


if I try to start snort using the /etc/init.d/snortd script it runs it as:


/usr/sbin/snort -A fast -b -d -D -i eth0 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort


and I never see those snort u2 files instead I see:

/var/log/snort/snort.log.xxxxxxxxxxx


and barnyard2 seems to have an issue with reading those files.


If i manually run snort form (/usr/sbin/snort -c /etc/snort/snort.conf) without any options it then creates the right file type /var/log/snort/snort.u2.xxxxxxxx


It is almost like it is not reading /etc/snort/snort.conf?

If anyone has any ideas that would be great.


Thanks

Sounds like you aren’t loading them with your snort.conf correctly.  Either check the dynamicplugin directives to make sure it’s reference the correct directory, or uncomment the rules at the bottom of the snort.conf that are located in your SO_RULES_PATH.

Also make sure your SO_RULES_PATH is the correct directory.

unsupported file layout

I just updated snort via pulledpork and got this error.
 
FATAL ERROR: Failed to load /usr/local/lib/snort_dynamicrules/misc.so: /usr/local/lib/snort_dynamicrules/misc.so: unsupported file layout
 
A quick search of google doesn't show me anything with a file layout error.
 
I commented out misc.rules but snort still fails to start with the same error.

Dynamic Rule [X:XXXXX] was not initialized properly.

Hello Everyone,

 

I’ve been receiving an error on our IDS units here that displays the following: “snort[XXXXX]: Dynamic Rule [X:XXXXX] was not initialized properly.” It’s not one specific rule either its different almost every time.

 

This error occurs every 2-5 minutes. Its flooding our error report and I can’t seem to find any information on it. Any help would be Greatly Appreciated.

Re: Couple of questions.

You need to post to the snort lists please, not directly to me as there are others that might help you and faster.

This could be an issue with snort version vs rule version downloaded?  I've never seen that error.  It would probably also help to have more of the error from the logs.

Hi Jeremy,
 
Yea I kind of figured that. I just wasn't 100% sure.
 
I have added a bunch of rules to my threshold file and will continue to do so till the alerts aren't so crazy.
 
Thank you.

A nessus scan may or may not trigger alerts depending on the plugins you used to scan, the services you have listening and any firewalls or iptables rules that might be in place.  Which interface you have snort listening on is a matter of preference and what you are hoping to see/alert on.  If it's your gateway doing NAT and you monitor the wan interface, you won't get the client IP's that might be sending out bad things, or the client ip's that bad things talk too.  If you watch just the inside and it's secure then it might be boring.

In either case, you will have to do rule filtering, adjusting and white listing/thresholds of things you don't want to see, alerts you don't care about or machines that are false positives.  Snort is not just a turn it on and go thing.  The fact that you see alerts means it's working, now it's up to you to figure out what type of alerts you want to see and from where.
