Burning DVDs in FreeBSD

Here are the steps I took to create a DVD using a Plextor 708UF DVD burner connected to my ancient laptop over Firewire through an Adaptec DuoConnect PC Card Adapter. First I installed sysutils/dvd+rw-tools as a package. Next I placed all of the files I wanted backed up into /mnt/.burn_to_dvd/ and proceeded to use growisofs.

orr:/root# growisofs -dvd-compat -Z /dev/cd0 -J -R /mnt/.burn_to_dvd/
Executing 'mkisofs -J -R /mnt/.burn_to_dvd/ | builtin_dd of=/dev/pass1 obs=32k seek=0'
:-( /dev/pass1: 2297888 blocks are free, 2637323 to be written
:-( write failed: No space left on device

Oops. I put too many files into the directory. They are larger than the DVD capacity of 4.3 GB. After removing a file, I proceed to burn the DVD.

orr:/mnt# du -h .burn_to_dvd/
4.2G    .burn_to_dvd/
orr:/mnt# growisofs -dvd-compat -Z /dev/cd0 -J -R /mnt/.burn_to_dvd/
Executing 'mkisofs -J -R /mnt/.burn_to_dvd/ | builtin_dd of=/dev/pass1 obs=32k seek=0'
/dev/pass1: "Current Write Speed" is 4.1x1385KBps.

I'm able to mount the new DVD and check its capacity.

orr:/mnt# mount -t cd9660 /dev/cd0 /cdrom
orr:/mnt# df -h /cdrom

/dev/cd0      4.2G    4.2G      0B   100%    /cdrom

That's it -- very simple.

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

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.

Volume 4 offers early white papers that Mr. Bejtlich wrote as a network defender, either for technica...
