Hi Patrick:

Thanks a lot for your wonderful work on the Snort Install Manual. It was
a big help.

It seems my original email was mangled. Here is database portion of the
output from "snort -T -c /etc/snort/snort.conf -g"

database: compiled support for ( mysql )
database: configured to use mysql
database:          user = snort
database: password is set
database: database name = snort
database:          host = localhost
database:   sensor name = copper:eth0
database:     sensor id = 3
database: schema version = 106
database: using the "log" facility

This shows that the database access was fine. There was something in the
snort.conf file that was preventing Snort from sniffing. I copied a
snort.conf file from the Internet and it is working now.

Thanks a lot.

Regards.

Looks like you have the output database mysql line commented out

Subject: [Snort-users] Snort not capturing data

Dear Friends:

I am new to Snort. I have installed Snort on a Linux machine. I followed
the Snort Install Manual by (Saint) Patrick Harper and it was fairly
smooth. 

Unfortunately Snort is not capturing any data. When I login into mysql
as the snort user, there is 0 records in the events table. I have ACID
running and that shows 0 sensor. Though the output from the sensor table
in the snort database has the following output.
+-----+-------------+-----------+--------+--------+----------+----------
+
| sid | hostname    | interface | filter | detail | encoding | last_cid
|
+-----+-------------+-----------+--------+--------+----------+----------
+|
|   3 | copper:eth0 | eth0      | NULL   |      1 |        0 |        0
|
+-----+-------------+-----------+--------+--------+----------+----------
+

I have put the output of the command  "snort -T -c /etc/snort/snort.conf
-i eth0 -g snort" and snort.conf file below.


I appreciate your help.

###################################################
# This file contains a sample snort configuration. 
# You can take the following steps to create your own custom
configuration: # #  1) Set the network variables for your network #  2)
Configure preprocessors #  3) Configure output plugins #  4) Customize
your rule set # ###################################################
# Step #1: Set the network variables:
#
# You must change the following variables to reflect your local network.
The # variable is currently setup for an RFC 1918 address space. # # You
can specify it explicitly as: 
#
# var HOME_NET 10.1.1.0/24
#
# or use global variable $<interfacename>_ADDRESS which will be always #
initialized to IP address and netmask of the network interface which you
run # snort at.  Under Windows, this must be specified as #
$(<interfacename>_ADDRESS), such as: #
$(\Device\Packet_{12345678-90AB-CDEF-1234567890AB}_ADDRESS)
#
# var HOME_NET $eth0_ADDRESS
#
# You can specify lists of IP addresses for HOME_NET
# by separating the IPs with commas like this:
#
# var HOME_NET [10.1.1.0/24,192.168.1.0/24]
#
# MAKE SURE YOU DON'T PLACE ANY SPACES IN YOUR LIST!
#
# or you can specify the variable to be any IP address
# like this:

var HOME_NET any

# Set up the external network addresses as well.  A good start may be
"any" var EXTERNAL_NET any

# Configure your server lists.  This allows snort to only look for
attacks to # systems that have a service up.  Why look for HTTP attacks
if you are not # running a web server?  This allows quick filtering
based on IP addresses # These configurations MUST follow the same
configuration scheme as defined # above for $HOME_NET.  

# List of DNS servers on your network 
var DNS_SERVERS $HOME_NET

# List of SMTP servers on your network
var SMTP_SERVERS $HOME_NET

# List of web servers on your network
var HTTP_SERVERS $HOME_NET

# List of sql servers on your network 
var SQL_SERVERS $HOME_NET

# List of telnet servers on your network
var TELNET_SERVERS $HOME_NET

# List of snmp servers on your network
var SNMP_SERVERS $HOME_NET

# Configure your service ports.  This allows snort to look for attacks
destined # to a specific application only on the ports that application
runs on.  For # example, if you run a web server on port 8081, set your
HTTP_PORTS variable # like this: # # var HTTP_PORTS 8081 # # Port lists
must either be continuous [eg 80:8080], or a single port [eg 80]. # We
will adding support for a real list of ports in the future.

# Ports you run web servers on
#
# Please note:  [80,8080] does not work.
# If you wish to define multiple HTTP ports,
# 
## var HTTP_PORTS 80 
## include somefile.rules 
## var HTTP_PORTS 8080
## include somefile.rules 
var HTTP_PORTS 80

# Ports you want to look for SHELLCODE on.
var SHELLCODE_PORTS !80

# Ports you do oracle attacks on
var ORACLE_PORTS 1521

# other variables
# 
# AIM servers.  AOL has a habit of adding new AIM servers, so instead of
# modifying the signatures when they do, we add them to this list of
servers. var AIM_SERVERS
[64.12.24.0/24,64.12.25.0/24,64.12.26.14/24,64.12.28.0/24,64.12.29.0/24,

#
# Stop Alerts on T/TCP alerts
#
# In snort 2.0.1 and above, this only alerts when a TCP option is
detected # that shows T/TCP being actively used on the network.  If this
is normal # behavior for your network, disable the next option. # #
config disable_tcpopt_ttcp_alerts # # Stop Alerts on all other TCPOption

# Configure the detection engine
# ===============================
#
# Use a different pattern matcher in case you have a machine with very
limited # resources: # # config detection: search-method lowmem

###################################################
# Step #2: Configure preprocessors
#
# General configuration for preprocessors is of 
# the form
# preprocessor <name_of_processor>: <configuration_options>

# Configure Flow tracking module
# -------------------------------
#
# The Flow tracking module is meant to start unifying the state keeping
# mechanisms of snort into a single place. Right now, only a portscan
detector # is implemented but in the long term,  many of the stateful
subsystems of # snort will be migrated over to becoming flow plugins.
This must be enabled # for flow-portscan to work correctly. # # See
README.flow for additional information # preprocessor flow:
stats_interval 0 hash 2

# frag2: IP defragmentation support
# -------------------------------
# This preprocessor performs IP defragmentation.  This plugin will also
detect # people launching fragmentation attacks (usually DoS) against
hosts.  No # arguments loads the default configuration of the
preprocessor, which is a 60 # second timeout and a 4MB fragment buffer. 

# The following (comma delimited) options are available for frag2
#    timeout [seconds] - sets the number of [seconds] that an unfinished

#                        fragment will be kept around waiting for
completion,
#                        if this time expires the fragment will be
flushed
#    memcap [bytes] - limit frag2 memory usage to [number] bytes
#                      (default:  4194304)
#
#    min_ttl [number] - minimum ttl to accept
# 
#    ttl_limit [number] - difference of ttl to accept without alerting
#                         will cause false positves with router flap
# 
# Frag2 uses Generator ID 113 and uses the following SIDS 
# for that GID:
#  SID     Event description
# -----   -------------------
#   1       Oversized fragment (reassembled frag > 64k bytes)
#   2       Teardrop-type attack

preprocessor frag2

# stream4: stateful inspection/stream reassembly for Snort
#----------------------------------------------------------------------
# Use in concert with the -z [all|est] command line switch to defeat
stick/snot # against TCP rules.  Also performs full TCP stream
reassembly, stateful # inspection of TCP streams, etc.  Can statefully
detect various portscan # types, fingerprinting, ECN, etc.

# stateful inspection directive
# no arguments loads the defaults (timeout 30, memcap 8388608) # options
(options are comma delimited):
#   detect_scans - stream4 will detect stealth portscans and generate
alerts
#                  when it sees them when this option is set
#   detect_state_problems - detect TCP state problems, this tends to be
very
#                           noisy because there are a lot of crappy ip
stack
#                           implementations out there
#
#   disable_evasion_alerts - turn off the possibly noisy mitigation of
#                            overlapping sequences.
#
#
#   min_ttl [number]       - set a minium ttl that snort will accept to
#                            stream reassembly
#
#   ttl_limit [number]     - differential of the initial ttl on a
session versus
#                             the normal that someone may be playing
games.
#                             Routing flap may cause lots of false
positives.
# 
#   keepstats [machine|binary] - keep session statistics, add "machine"
to 
#                         get them in a flat format for machine reading,
add
#                         "binary" to get them in a unified binary
output 
#                         format
#   noinspect - turn off stateful inspection only
#   timeout [number] - set the session timeout counter to [number]
seconds,
#                      default is 30 seconds
#   memcap [number] - limit stream4 memory usage to [number] bytes
#   log_flushed_streams - if an event is detected on a stream this
option will
#                         cause all packets that are stored in the
stream4
#                         packet buffers to be flushed to disk.  This
only 
#                         works when logging in pcap mode!
#
# Stream4 uses Generator ID 111 and uses the following SIDS 
# for that GID:
#  SID     Event description
# -----   -------------------
#   1       Stealth activity
#   2       Evasive RST packet
#   3       Evasive TCP packet retransmission
#   4       TCP Window violation

LOG_AUTH LOG_ALERT # output alert_syslog: host=hostname:port, LOG_AUTH
LOG_ALERT

# log_tcpdump: log packets in binary tcpdump format
# -------------------------------------------------
# The only argument is the output file name.
#
output log_tcpdump: tcpdump.log

# database: log to a variety of databases
# ---------------------------------------
# See the README.database file for more information about configuring #
and using this plugin. # output database: log, mysql, user=snort
password=google dbname=snort host=localhost # output database: alert,
postgresql, user=snort dbname=snort # output database: log, odbc,
user=snort dbname=snort # output database: log, mssql, dbname=snort
user=snort password=test # output database: log, oracle, dbname=snort
user=snort password=test

# unified: Snort unified binary format alerting and logging
# -------------------------------------------------------------
# The unified output plugin provides two new formats for logging and
generating # alerts from Snort, the "unified" format.  The unified
format is a straight # binary format for logging data out of Snort that
is designed to be fast and # efficient.  Used with barnyard (the new
alert/log processor), most of the # overhead for logging and alerting to
various slow storage mechanisms such as # databases or the network can
now be avoided.  
#
# Check out the spo_unified.h file for the data formats.
#
# Two arguments are supported.
#    filename - base filename to write to (current time_t is appended)
#    limit    - maximum size of spool file in MB (default: 128)
#
# output alert_unified: filename snort.alert, limit 128
# output log_unified: filename snort.log, limit 128

# You can optionally define new rule types and associate one or more
output # plugins specifically to that type. # # This example will create
a type that will log to just tcpdump. # ruletype suspicious # {
#   type log
#   output log_tcpdump: suspicious.log
# }
#
# EXAMPLE RULE FOR SUSPICIOUS RULETYPE:
# suspicious tcp $HOME_NET any -> $HOME_NET 6667 (msg:"Internal IRC
Server";) # # This example will create a rule type that will log to
syslog and a mysql # database: # ruletype redalert # {
#   type alert
#   output alert_syslog: LOG_AUTH LOG_ALERT
#   output database: log, mysql, user=snort dbname=snort host=localhost
# }
#
# EXAMPLE RULE FOR REDALERT RULETYPE:
# redalert tcp $HOME_NET any -> $EXTERNAL_NET 31337 \
#   (msg:"Someone is being LEET"; flags:A+;)

# Step #4: Customize your rule set
#
# Up to date snort rules are available at http://www.snort.org # # The
snort web site has documentation about how to write your own custom
snort # rules. # # The rules included with this distribution generate
alerts based on on # suspicious activity. Depending on your network
environment, your security # policies, and what you consider to be
suspicious, some of these rules may # either generate false positives
ore may be detecting activity you consider to # be acceptable;
therefore, you are encouraged to comment out rules that are # not
applicable in your environment. # # The following individuals
contributed many of rules in this distribution. # # Credits:

#=========================================
# Include all relevant rulesets here 
# 
# The following rulesets are disabled by default:
#
#   web-attacks, backdoor, shellcode, policy, porn, info, icmp-info,
virus,
#   chat, multimedia, and p2p
#            
# These rules are either site policy specific or require tuning in order
to not # generate false positive alerts in most enviornments. # 
# Please read the specific include file for more information and #
README.alert_order for how rule ordering affects how alerts are
triggered. #=========================================
