Snort Startup Scripts for various OSes have been updated!

Many thanks to one of our very dedicated Snort Community members, William Parker.  In his guides (also posted on the documentation page of Snort.org) he has embedded some Snort Startup scripts.

Because some people are having problems with copy and pasting out of the PDF documentation, so Mr. Parker put these startup scripts in their own files and sent them to me.  I created a special section on Snort.org/docs just for startup scripts, and they are all there!

Many thanks to Mr. Parker for updating his scripts based on user feedback, and the new ones are now up.

Barnyard2 2-1.13-BETA is now available!

We are happy to announce the Availability of Barnyard2 2-1.13-BETA which can be downloaded from HERE: https://github.com/firnsy/barnyard2.git

This release is a bug fix release that also introduce a few new features and enhancements


=====================
UPGRADING REQUIREMENT
=====================
----------------------
If you are upgrading to barnyard2 2-1.13 Build 325 or above from a previous version  that is not 2-1.13 and using the output database.

***** We highly recommend ******
To delete every row in your sig_reference table. (DELETE FROM sig_reference;) The table will be re-populated at  process startup, and has no impact on historical data.
----------------------
=====================
UPGRADING REQUIREMENT
=====================





Feature request:
----------------
Phil Daws:        Add interface and hostname field to spo_alert_csv if specified.

Jorge Pinto:      spo_syslog_full support for ASCII,BASE64 payload

Jason Brvenik:  variables .....(a long time ago, sorry :P)

Martin Olsson:  Remove some useless verbosity unless ./configure --enable-debug is specified and proper flag are used (spo_database and sid-msg.mapv2)

*And all other barnyard2 users who help and contribute.

Bug report:
-----------
Martin Olsson:              - bug in sig_reference generation and good discussions.

John Eure and others   - autogen.sh could cause some issue on some system so [autoreconf -fv --install] is not set to autoreconf -fvi

John Naggets               - spo_database: could stop barnyard2 from processing new event if some packets with ip option where processed and option_len  was null.

Fäbu Hufi                     - spo_syslog_full: in complete mode was printing wrong ip version information and ip header length.

*And all other barnyard2 users who help and contribute.


New feature:
------------


Support for sid-msg.map Version 2 format.
-------
A new sig-msg.map format can be generated by pulledpok (upcoming release, already in svn). Detection of sid-msg.map version is done by a simple header in the  file that shouldn't be altered if you want it to be processed correctly.

sig-msg.map version 2 format extend the information already present in the sid-msg.map file created from rules.

This new format version allow signature  pre-population if users are using output database method with  barnyard2 2-1.13 and above.
______________________
sid-msg.map v1 format:
______________________
SID || MSG || REF 1 || REF N
sid := integer
msg := string
ref := string
______________________
sid-msg.map v2 format:
______________________
GID || SID || REV || CLASSIFICATION || PRIORITY || MSG || REF 1 || REF N
gid := integer
sid := integer
rev := integer
classification := string (if NULL set to NOCLASS)
priority := integer (if prio == 0, classification priority is used)
msg := string
ref := string
=====================
generator (GID, gen-msg.map) are defaulted to the following value if their information is not overruled in sid-msg.map v2 file via processing of preprocessor.rules:
revision 1
classification 0
priority 3
If generator message is present in the sid-msg.map v2 file, and gen-msg.map message are longer (more comprehensive by string length), gen-msg.map messages are used instead of sid-msg.map v2 file generator messages.
=====================
 -------


Signature/event logging suppression at spooler level
-------
Read doc/README.sig_suppression
configuration file Variables:
-------

Barnyard2 configuration Variables
 -------
You can now use [var VARNAME value] in the barnyard2 configuration file and every instance of $VARNAME will get replaced by value.
Note that variable declaration order is important only you include a variable in a variable.
EX (is VALID):
 var INTERFACE ethX
 var PATH /var/log/IDS
 var LOG $PATH/$INTERFACE/log
 var ARCHIVE $PATH/$INTERFACE/archive
 EX (is INVALID):
 var LOG $PATH/$INTERFACE/log
 var ARCHIVE $PATH/$INTERFACE/archive
 var INTERFACE ethX
 var PATH /var/log/IDS
 -------

new output database configuration keyword
-------

Keywords connection_limit and reconnect_sleep_time where added in 2-1.10 but where "undocumented" and shouldn't be modified unless you encounter connectivity issue.

connection_limit <integer>: default 10  - The maximum number of time that barnyard2 will
tolerate a transaction failure and or database connection failure.

reconnect_sleep_time <integer> : default 5 - The number of seconds to sleep between connection retry.

disable_signature_reference_table - Tell the output plugin not to synchronize the sig_reference table in the schema. This option will speedup the process, especially if you use sid-msg.mapv2 file or  have a lot of signature already in databases. (Make sure that you
do not need that information before enabling this)
 -------


Enjoy and do not hesitate to send feedback/suggestion/feature request.

The barnyard2 team.

Snort 2.9.4.5 is now available on snort.org, at
https://www.snort.org/downloads in the Latest Release section.

******
Please Note:
We understand that there may be some confusion by moving from 2.9.4.1
to 2.9.4.5, and we apologize for that. We are aligning our internal
build numbers with our open source build versions to make versioning
and distribution easier on the backend. This will help us in ensuring
that the correct versions of rules are available for the supported
versions of Snort.
******

Snort 2.9.4.5 includes changes for the following:

[*] Improvements

* Removed proxy information from HTTP URI searching so that the URI
matches are just on the actual URI so that offsets work as expected.

Thanks to L0rd Ch0de1m0rt for reporting the issue.


* Addressed an issue when logging of packet data via unified2 when
alerting on a packet with multiple HTTP PDUs.

* Continue to search for patterns within the HTTP URI until the end of
the URI.

See the Release Notes and ChangeLog for more details.

Please submit bugs, questions, and feedback to bugs@snort.org.

Happy Snorting!
