DragonFly BSD

Historical links are the accidental theme this week. RFC Reader.  For those uncomfortable with plaintext?  (via) The truth about C & Unix history.  An oldie but goodie.  (via) After several decades, there’s still no standard for querying ... [More] registration data, surprisingly.  There’s something coming together, though. Plan-55A, store and forward messaging – on paper.  (via) 1980s sci-fi show […] [Less]

I got this done early, for once. Dissecting OpenBSD’s divert(4).  (via) Running ownCloud with httpd on OpenBSD  (via) OpenBSD 2014 by the numbers.  (via) Code rot & OpenBSD.  Many comments at the original link.  (via) Accessing radio hardware ... [More] switches in NetBSD. What does this Etherswitch framework do? FreeBSD now has Elf Tool Chain utilities, which […] [Less]

I’m breaking my normal weekend posting schedule to note that DragonFly 4.0.2 images are now linked on the main site and on mirrors now/soon.

DragonFly 4.0.2 has been tagged.  I’m building the release images now.  If you’re already running 4.0.1 it’ll be easy enough to upgrade to; you will want to catch up to this commit fixing a quiet memory issue.

The CAM layer in DragonFly has had its big lock removed/been marked MPSAFE, so you will notice a performance increase when using multiple disks.  (assuming you aren’t throughput-limited, of course.)

That’s Virtual Private Server, if you don’t know the term.  I mentioned VPSs and BSD before in a In Other BSDs article, but “Ed” found an article specifically about installing DragonFly on Vultr.

There’s a FreeBSD Forums thread about ZFS and Hammer, as several people have pointed out to me.  It’s interesting to see, but there isn’t a lot of quantitative discussion.  (It’s a forum post, not a white paper, though.)

Do you remember the BSDNow story a while ago about a Tanzanian community effort using FreeBSD to build a library?  They’re looking at DragonFly, too, because of the low resource requirements.  From that discussion: a hardware reason for an ‘indefinite wait buffer’ error, and a note on how to most efficiently download packages for multiple […]

Sepherosa Ziehau has posted a note that V4-mapped addressing is no longer supported in DragonFly.  You will need to do a full buildworld/buildkernel if you are running master.  Also, TCP MTU path discovery is on by default.  Also also, he’s added ... [More] a SOL_SOCKET/SO_CPUINT socket option for use to reduce load in heavy network activity.  As usual, I don’t […] [Less]

You can now control your backlight settings through sysctl and enjoy greater video support/stability – as long as you are using a i915 video chipset on DragonFly.
