Master snort.conf's have been updated
With the addition of the new ports in all the configurations, I've went ahead and updated our master snort.conf examples from the VRT on the Snort.conf configuration page:
https://www.snort.org/configurations
By the way -- In case you want to find that page in the future, just remember to Google "Snort.conf configurations" It's the first result.
Happy 2012!

Mirroring traffic to Snort using a Consumer Grade Router
Thanks again to William Parker for providing some excellent documentation for the rest of the Snort community.
Just posted to http://www.snort.org/docs is a guide on how to use a consumer grade router (Linksys, D-Link, NetGear, etc) to mirror your traffic in your network over to a box running Snort.
Take a look at the doc!
Thanks Bill!

Snort Startup scripts for various OSes posted!
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!

Snort 2.9.4.0 has been released!
Snort 2.9.4 is now available on snort.org, at
https://www.snort.org/downloads in the Latest Release section.
************ Please note: 2.9.3.1 & later packages are signed with a new PGP key (that key is signed with the previous key). ************
Snort 2.9.4 includes changes for the following:
[*] New additions
* Consolidation of IPv6 -- now only a single build supports both IPv4 & IPv6, and removal of the IPv4 "only" code paths.
* File API and improvements to file processing for HTTP downloads and email attachments via SMTP, POP, and IMAP to facilitate broader file support
* Use of address space ID for tracking Frag & Stream connections when it is available with the DAQ
* Logging of packet data that triggers PPM for post-analysis via Snort event
* Decoding of IPv6 with PPPoE
* Added an API call to add a service to a host in the attribute table. Remove the unused live attribute update code.
[*] Improvements
* Update to Stream5 PAF for handling gaps in the sequence numbers of packets being reassembled.
* Selection of the Stream TCP policy based on the server rather than the destination of first packet seen by Snort
* Allow disabling of global thresholds via a count of -1
* Prevent blocking duplicate SYNs when using inline normalization
* Add SSLv3 backwards compatibility support for SSLv2 ClientHello messages
* Allow active responses to packets without data (eg, a TCP SYN)
* Changed logic of option evaluations for shared library rules that use a custom evaluation function to match that of the builtin logic when the NOT_FLAG is used. The 'NOT' matching now happens within each of the individual rule option evaluation functions.
* Updated SMTP preprocessor to better handle commands that have corresponding data on a subsequent line to reduce false positives. 3 commands fall into this category - X-EXPS, XEXCH50, and BDAT.
* Improve support for encapsulated & tunneling protocols to block or fastpath a connection within the tunnel rather applying that to the whole tunnel.
Please see the Release Notes and ChangeLog for more details.
Please submit bugs, questions, and feedback to bugs@snort.org.
Happy Snorting! The Snort Release Team
