Shutdown style


If you’ve only ever used to ‘shutdown -h now‘ to halt a machine, Sepherosa Ziehau reminds that ‘shutdown -p now‘ is the way to get the server powered off.

Whee, tftp!


Joseph Garcia got to fight with tftp on DragonFly; he wrote down the rather torturous procedure he had to follow, which may help anyone else with a Cisco router that needs to be configured.

Blogged on Con


Reader LabThug helpfully pointed out that the blog at http://opensource.weblogsinc.com/ has been talking about the events at NYCBSDCON. Oh, I’m kicking myself for not going. Of special interest to readers here is a writeup on Jeffrey Hsu’s DragonFly talk.

Mustang next


Emiel Kollof pointed out that Mustang is going to be the next release of Java; we have a chance to get some support for DragonFly in now.

Crazy bug tracker work


Matthew Dillon didn’t like the idea of a Java-based bug tracker, so he’s rolling his own. As part of it, his Backplane databse will probably be used as the back-end for it, though under the GPL.

Preview, Release updates


Matthew Dillon has committed a number of bug fixes back to Preview, and will bring them into 1.2 Release this weekend.

Test new changes for 1.2.6


Matthew Dillon just added a number of bugfixes to the release verion of DragonFly (1.2.5). If you have a SMP machine running 1.2.5, he’d appreciate a test before we go to 1.2.6.

UnixReview.com: book reviews


UnixReview.com has just two book reviews this week, both of which are relevant: Advanced Programming in the Unix Environment, and the more focused “Cisco IP Communications Express: CallManager Express with Cisco Unity Express“.

SCSI gone scuzzy


Matthew Dillon happened to write something about RAID vs. SATA drives that says, among other things, picking SCSI over SATA drives doesn’t make financial sense.

Bug tracking almost selected


Matthew Dillon started to think about writing his own bug tracker, to which the genral response was “Keep up the cool DragonFly work!”. Many people are leaning towards Jira, though Hiten Pandya still wants to evaluate Bugzilla or cvstrac if Jira does not work out by the time of the next release.

Recommendations


Matthew Dillon, like many people, thinks hardware RAID is generally better. In fact, he’s using cards from 3ware.

Also, Simon ‘corecode’ Schubert looked at the bug tracking program jira, and liked what he saw. He liked it so much, he set up a test installation.

New Certification Survey

More on bug tracking


Jeremy Messenger suggested this comparison list for bug trackers; Hiten Pandya also wants to look at MySQL’s Eventum.

GCC updated


Simon ‘corecode’ Schubert has updated gcc to version 4.0.1.

If you want to build the system using gcc version 4, you must put WANT_GCC40=yes into make.conf and rebuild your system. Then, rebuild again with the environment variable CCVER set to ‘gcc40′.

The first build builds gcc4 using your existing compiler; the second uses it during the build. I have not done this myself, so be careful.

outage and new machines


dragonflybsd.org may be down at times this weekend, as Matthew Dillon is adding/moving a whole lot of hardware.

Update: There’s downtime tonight, starting 9 PM PDT. If you have data on leaf:/unused3, it’ll be gone.

NYCBSDCon preregistration closing


Brad Schonhorst kindly sent along this announcement about NYCBSDCon:

“There are only 2 days left to preregister for the first ever NYCBSDCon, to be held September 17th at Columbia University, in the Davis Auditorium.”

There’s more at the NYCBSDCon site. Among other notable speakers, our very own Jeffrey Hsu will be presenting “History, Goals, Objectives, and Structure of DragonFlyBSD”. I’d really like to go see this.

Daemon Tomato


Author Neil Gaiman found a tomato that looks like it has a horn; add a matching second horn and it would look like Beastie.

Incidentally, Neil Gaiman has little to do with BSD, but he has written some excellent books and comics.

More on new hardware


The systems mentioned in a previous post as being ordered for dragonflybsd.org will be “ASUS A8N-SLI Deluxe”, which means that they will probably be good choices for supported hardware.

More hardware


Matthew Dillon’s ordering some new hardware for dragonflybsd.org. Among other improvements, there will be a new machine specifically for building world, kernel, and pkgsrc.

Simon ‘corecode’ Schubert posted a wiki page that can be used in defining needs for a DragonFly bug tracking system. Also, Peter Avalos added the program Jira as a candidate.

More stats (ubench)


Tomaž Borštnar used ubench to test DragonFly and various FreeBSD systems, and wrote up the results.

Speaking of benchmarks, the fefe.de benchmarks done some time ago may be coming in for a second round of tests. Of course, that blog entry is in German, so I’m going on what Hubert Feyrer said.

Got stats?


If you’ve been running a DragonFly mirror, the BSD Certification Group would like to know your download stats. Several people have quoted healthy numbers. (post them to kernel@dragonflybsd.org, if you have them)

Why pkgsrc, and disk sizing


Matthew Dillon wrote a little more on why he thinks pkgsrc is the best direction for DragonFly.

He also followed up on a separate thread describing the current disk size limits for UFS1. Hiten Pandya added comments, too.

Bug tracking one way or another


Simon ‘corecode’ Schubert proposed using cvstrac for bug tracking, and he has set up an example. Scott Ullrich has already been using cvstrac for pfsense. However, Hiten Pandya was intending to set up Bugzilla.

All ISO types available again


Simon ‘corecode’ Schubert now has release, development, and preview versions of DragonFly built regularly on his server. In addition, he has the most recent version source for each type available as a .tar.bz2 file, for those who don’t want to grab it through cvsup.

pkgsrc to be in next Release


The next release of DragonFly (1.4) will include pkgsrc, as Matthew Dillon described in a recent post. For those of us with 1.2 systems, some work is being done to create binary packages now, to ease the transition. The Wiki has some documentation on using pkgsrc.
