This is a compilation of several posts I found while researching this procedure and I wanted to save the steps. I’m sure I’ll need them again.

My “MAC” is running 10.10.5 and the NFS server is Ubuntu Linux 14.04 with ZOL.

Oracle archive log cleanup script

Here’s a quick bash script to clean up archive logs older than a week. It reads the Oracle SIDs from /etc/oratab and invokes rman for each SID. One could put this in cron to be run once a day to keep disk space usage in check.

Installing systemtap on CentOS 7

I recently had the need to install systemtap on one of my CentOS 7 VMs and the process isn’t as straight forward as it should be. It seems not all packages needed are built for all revisions of the kernel. After much searching, I managed to get this working and wanted to archive this procedure.

Focaccia Style Flax Bread


  • 2 cups flax seed meal
  • 1 Tablespoon baking powder
  • 1 teaspoon salt
  • 5 beaten eggs
  • 1/2 cup water
  • 1/4 cup oil


Preheat oven to 350 F. Prepare pan (a 10×15 pan with sides works best) with oiled parchment paper or a silicone mat.

  1. Mix dry ingredients well – a whisk works well.
  2. Add wet to dry, and combine well. Make sure there aren’t obvious strings of egg white hanging out in the batter.
  3. Let batter set for 2 to 3 minutes to thicken up some (leave it too long and it gets past the point where it’s easy to spread.)
  4. Pour batter onto pan. Because it’s going to tend to mound in the middle, you’ll get a more even thickness if you spread it away from the center somewhat, in roughly a rectangle an inch or two from the sides of the pan (you can go all the way to the edge, but it will be thinner).
  5. Bake for about 20 minutes, until it springs back when you touch the top and/or is visibly browning even more than flax already is.
  6. Cool and cut into whatever size slices you want. You don’t need a sharp knife; I usually just cut it with a spatula.

FreeBSD / FreeNAS Clone Jail

I recently had the need to update my shiny new FreeBSD jailed server because I wanted to migrate to WordPress. I didn’t want to bring down the existing server while I did the install and converted my content so I managed to clone my existing jailed server using warden:

 warden export name_of_jail --dir=/directory_for_warden_file 

This will take a while… Once done, you can import the warden file creating a new jail:

 warden import jail_warden_file.wdn --host=jailbird --ipv4= 

You’ve now got a cloned jail and a template for creating other jailed servers.
