Splunk 4.x on FreeBSD 8.x using compat6x Libraries

Two years ago I posted Splunk on FreeBSD 7.0 showing how to use the FreeBSD compat6x libraries to run the 3.4 version of Splunk compiled for FreeBSD 6.x. I decided to try this again, except using the newest Splunk on an amd64 FreeBSD system.

As you can see below, it took me only a few minutes to get the system running thanks to the precompiled compat6x-amd64 package. If I needed to install on i386, I could have used the ports tree.

And that's it! I pointed my Web browser to the FreeBSD server and I accessed Splunk. Kudos to Splunk for providing a free version of their product to run in this manner!

Postscript: I realized Splunk installs to /opt, which on this system lives in /, which is small. So, I made this change after stopping Splunk:

r200a# mv /opt /nsm/
r200a# ln -s /nsm/opt/ /opt

That put Splunk in the larger /nsm partition. I should have created the symlink before installing, but no real harm was done anyway.

Richard,

You can also just move $SPLUNK_HOME to /nsm. We should automagically figure out where we are, but just in case you can set $SPLUNK_HOME in ./splunk/etc/splunk-launch.conf. You can use this same file to change the $SPLUNK_DB directory or set a $SPLUNK_BIND_IP.

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Image
Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti...

  I've completed the TaoSecurity Blog book series . The new book is  The Best of TaoSecurity Blog, Volume 4: Beyond the Blog with Articles, Testimony, and Scholarship .  It's available now for Kindle , and I'm working on the print edition.  I'm running a 50% off promo on Volumes 1-3 on Kindle through midnight 20 April. Take advantage before the prices go back up. I described the new title thus: Go beyond TaoSecurity Blog with this new volume from author Richard Bejtlich. In the first three volumes of the series, Mr. Bejtlich selected and republished the very best entries from 18 years of writing and over 18 million blog views, along with commentaries and additional material.  In this title, Mr. Bejtlich collects material that has not been published elsewhere, including articles that are no longer available or are stored in assorted digital or physical archives. Volume 4 offers early white papers that Mr. Bejtlich wrote as a network defender, either for technica...
