DNS Change Regression Testing

For those who have needed to make a bunch of DNS changes and want to verify what the effect of those changes are, here is a little shell script that does a sort of regression test. Basically, it tells you what changes were made to a zone so you can see if any major mistakes were made.

The usage is simple try dnscheck -? for a list of options. It isn’t the fanciest thing in the world, but for those who need it, it might be helpful.

Open it in your favorite text editor to set the basic configuration options and make it executable and you are on your way.

Perfect or Just Good

I hear a great quote the other day. I think it cam from the guys who manage the Subversion project.

“Perfect is the enemy of Good”

It reminds me of the analog…

“Good execution is more important than a good plan”

I can’t tell you how many times I have been in groups that have argued endlessly about the very best course of action, only to have disagreement and division when it came time to execute.
