Capital Area BSD Users Group

April’s meeting consisted of a slightly larger than normal crowd. Having a guest speaker must have had something to do with that.

The meeting opened with Todd Carson talking about his experience finding and submitting a bug which turned into an OpenBSD Errata entry.

Following Todd’s talk, Theo Schlossnagle, CEO of OmniTI Computer Consulting, gave live demonstrations of both ZFS and DTrace. Theo showed some of the many features of ZFS while demonstrating some of them on live Solaris systems and his Apple laptop, including snapshotting. Then, he showed and described how to use DTrace to see what a process is doing. Without concrete problems to solve, it’s difficult to show DTrace in all of its glory, but Theo managed to give a great demonstration. To paraphrase: the hard part is coming up with good questions to ask DTrace.

Then, as an aside, Theo showed us how valgrind (on Linux) can point you to exactly where the bugs in your code are.

Thanks to both Todd and Theo for taking the time to talk to us. See you next month.

This month we’ll be meeting on Tuesday, April 29, 6:30pm EST at Raba in Columbia, MD. Directions

Theo Schlossnagle, CEO of OmniTI Computer Consulting, will give a talk on ZFS and Dtrace.  Both of these are available in FreeBSD, although many of the useful features are not integrated yet.  Theo will introduce both technologies and give practical examples (on OpenSolaris) for using them in engineering environments.

Todd Carson will also give a brief talk on how his diff became OpenBSD 4.2 Errata entry 008.

Afterwards, we’ll congregate at a nearby water hole for food and drinks, and to celebrate the release of OpenBSD 4.3!

The March meeting consisted of a brief presentation (given by me) about using CVS for Configuration Management. We had a fairly light crowd comprised of most of “the regulars”. After talking about CVS, we also discussed Nagios and I gave a demo of how I’m using it to monitor my home network.

Following the meeting, most of us convened at the Dog Pub for some pizza and beer (or soda, as the case may be).

Thanks to everyone that made it out.

Our February meeting consisted of Sysadmin Games (the brainchild of Jason Dixon). Jason brought with him a “server” (beige box) running some form of Linux and VMware Server. He had prepared blank VMware guest systems ready to be loaded with Open, Net, Free or Dragonfly BSD. After a quick trivia contest to choose which team was assigned which BSD, we got started.

The goal was to install your assigned BSD, configure networking, a web server with HTTPS and the firewall. While we were allowed “shout-outs” for help, no one seemed to use that and preferred to use their 10 minute “web search” lifeline. All of the teams fared very well, running into small problems along the way. Only one team completed the task with perfection.

All in all, Sysadmin Games was a huge success. We will have to start planning for future competitions.

Update: (notes from Jason)

I took notes during the meeting to track how teams were doing, how well the server was holding up, and what can be done better in the future.  Surprisingly, everything went very smoothly except for the host platform (VMware on CentOS) choking at times.  It seems that VMware doesn’t behave nicely when you have four teams beating on the vmware console over the network.  Regardless, we managed to clear those minor obstacles and every team finished with a “passing” score.

Our January 29, 2008 meeting marks CapBUG’s one year birthday. We celebrated with a great Samba talk me Johan Huldtgren, a GNU/screen talk by me and a special BSD Cake that Patrick Thomasson brought for the group.

After the meeting, we tried the Dog Pub for some pizza and beer. I thought it was OK.

Thanks to the CapBUG members and contributors for making our first year a great one. I hope the next year will be just as good (or better).

See you next month!

This meeting marks CapBUG’s 1 year anniversary. For this meeting, we’ll gather at my office in Columbia, MD again. To celebrate occasion, Patrick Thomasson will be bringing a special cake.

I will give a mini-talk about how I use GNU/screen, how I have it set up and how I use mutt and irssi. Following my talk, Johan Huldtgren will give a mini-talk about setting up a samba PDC/ file / print server.

The meeting audio will be broadcast (Slides will be linked here and URL for audio will be active during the talk). This should work fine for x11/vlc users (or systems with QuickTime support). A CapBUG representative will be available in #metabug on Freenode to field questions.

After the meeting, we’ll head over to The Dog Pub in Columbia for food and drinks.

We will hold our Nov/Dec combo meeting on Tuesday, December 18 at 6:30 at the Raba Office in Columbia, Maryland (the usual place). We’ll hit either The Green Turtle or Nottingham’s afterwards.

I will be giving a talk “Intro to Porting” mostly inspired by bernd@’s talk at OpenCON.

Due to unforeseen circumstances, we will not have a regular meeting this month and will just meet at Nottingham’s for “Beer & BSD”. We’ll eat food, drink beer, maybe play pool and talk about BSD, if it comes up.

See you there at 6:30 PM EDT.
