If you have a Hammer filesystem, and you want to roll the entire thing back to a previous snapshot – all files, everywhere – it can be accomplished with one command.
Did you know… ipfw/natd appears to be broken in DragonFly 2.6? Using pf is a better choice, at least, but I found it out the hard way.
Videos of the presentations at AsiaBSDCon 2010 are up; FreeBSD – The Unknown Giant has a number of them. Constantine A. Murenin’s Quiet Computing presentation is interesting, especially because it runs on DragonFly.
I’ve put a few of the reports from pkgsrc builds on DragonFly out. They’re all using pkgsrc-2010Q1, on i386/DragonFly 2.6, i386/DragonFly 2.7, and x86_64/DragonFly 2.7. The links in the reports go to the errors that caused each package to not build. If you happen to see something that has an easy fix, or that you really need to have working, please submit a fix.
Sorry – temporary power outage from high winds killed shiningsilence.com for about a day. Back now!
The ISO images have been filtering out to the mirrors for a while already, but the 2.6.3 release is officially announced on the DragonFly website and release page.
Binary packages built for DragonFly 2.6 and 2.7 from the most recent pkgsrc quarterly release, 2010Q1, are now available. The utility pkg_radd will access them, or you can download directly.
Sdävtaker has posted about the pre-call for papers, for BSDday Argentina. Check his post for topic and submission details.
As previously foreshadowed, BIND has been removed from the DragonFly base system. Instead, it’s installed from pkgsrc. Note that this includes tools like nslookup or host. Instructions after the jump.
From my email to users@:
- I almost have pkgsrc-2010Q1 builds done for every architecture, so I’ll point the default load location for pkg_radd to them within the next 24 hours.
- Are you still using a DragonFly system older than 2.4 and downloading binaries? If so, tell me.
- A project: enhancing pkg_search and pkg_radd to be able to tell when a package is missing because of license restrictions. Anyone want to try it?
DragonFly 2.6.3 is tagged and available, as previously planned. You can update to it normally, or go to a 2.6.3 ISO; available at various mirrors.
The latest BSDTalk brings you TheorArm and Robin Watts, with discussion of the ARM architecture; my favorite processor type that I’ve never used. TheorArm was recently relicensed from GPL to BSD thanks to the efforts from people at Google.
If you use Apache, as many people do, some of the default building choices have changed in pkgsrc. Read Matthias Scheler’s post for details.
The May issue of the Open Source Business Resource is out, and the theme is “Communications Enabled Applications”. Sounds obscure, but it’s about deriving a business advantage from networks. In fact, one article directly relates to one of my biggest current projects at work.
The May 2010 issue of BSD Magazine is out, with, among other articles, a writeup by yours truly about using HAMMER to access historical data.
I didn’t know about this, but Michael W. Lucas has a new book on the way: Network Flow Analysis. It should be good; his other (BSD-themed, generally) books are surprisingly accessible despite being very technical. (via)
A note, in part for my own benefit: the @reboot crontab entry is all you need to get a HAMMER mirror-stream going again after a reboot/shutdown.
Because of a number of problems, snapshot building hasn’t worked for some days. To fix this, some updates need to happen within DragonFly. This will mean a minor version bump to 2.6.3 in the next little while.
From a commenter on a previous post: Gentoo has a Google Summer of Code project porting portage to DragonFly, by student Naohiro Aota. I had no idea this was happening – this is interesting!
We’ve got 3 projects for Google Summer of Code 2010:
- “Device Mapper based Logical Volume Management”, by Alexander Hornung and mentored by Chuck Tuffli.
- “Porting kernel mode-setting, GEM and KMS, to DragonFlyBSD” by David Shao, mentored by Matthew Dillon
- “Coalesce + MPSAFE kevent, select, poll and wakeup” by Samuel Greear, mentored by Joe Talbott
We had a good number of excellent proposals, but only 3 slots from Google. There were only 12 spare slots by the end of the proposal period, too, meaning less than 1 spare per 10 organizations. I’d encourage people that applied and didn’t get in to still try the work; there were some neat proposals!
