I have made reservations for ten people at Victoria Gastro Pub for October 15 at 6:00 PM. There are currently 8 seats still available. Reply to the mailing list to save a spot.

I've asked Victoria's if we can switch the reservation to 6:30 (it wasn't available at OpenTable) and will update this post (and send an email to the list) if we change to 6:30.

See you there!

September 2009

We met at OmniTI again this month. Thank you, OmniTI!

I gave a talk [slides] about my recent migration for my mail/web server from i386 to amd64. I also discussed how I installed a ral(4) card in my Soekris to make it a wireless access point. Unfortunately, I think the card overheated my Soekris and crashed my firewall more than once. I have since removed the card.

Equipment:

After the meeting, we adjourned to Victoria Gastro Pub for dinner and libations.

August 2009

We met again at OmniTI (thank you for hosting us).

I (Mike Erdely) gave a short talk about using Bacula's encryption mechanisms to store data encrypted on the storage media. Devon O'Dell gave an informal but very interesting talk about the differences between pre-emptive and co-operatively scheduled threading. Then, Jason Dixon introduced us to his new creation: Blogsum. Keep a look out for capbug.org to be using it in the near future. Finally, I gave another short talk describing my experiences with turning off greylisting in OpenBSD's spamd(8).

After the awesome talks, we adjourned to Victoria Gastro Pub for some food and drink. A good time was had by all.

July 2009

This month we met at OmniTI again. I gave a talk entitled "Taking the plunge: A guide to tmux for screen users" (slides). It was a very informal talk with a lot of Q&A and some demonstrations. It should be noted that I love tmux.

After the talk we went to Victoria Gastro Pub for some food and libations.

May 2009

We again met at OmniTI this month. Jason gave a very good introduction to packet filters in general and OpenBSD PF (slides). After everyone was up to speed on the basics of OpenBSD PF, we used OmniTI's lab computers loaded with an OpenBSD 4.5 LiveCD that Jason created to get hands-on experience with PF. The lab computers were already booted to the CD, so all we had to do was log in. The computers were connected to a switch in the lab that was configured with two VLANs. Jason gave us tasks geared towards learning PF:
  1. Configure vlan100 interface to use DHCP
  2. Configure vlan200 interface with a static IP
  3. Nat on vlan100 for vlan200's network
  4. Allow SSH from outside to a host on the vlan 200 network
  5. Block all other inbound traffic
  6. Bonus: Give SSH priority over HTTP
