DNS Staying With The Times

My company signed a contract for a provider that uses TZO as their DNS provider. Now I have used TZO before (circa 2006-2007) and although their interface was archaic and there was no API, I accepted it because I was told they were reliable. As it happens, the service was fantastic and they are very reliable. I don’t think the service went down once the entire time I was using them. I ended up leaving the company and never saw the API or new interface come to fruition.

Cluster SSH with cSSHx

I am in the middle of building out a group of about 25 machines in a data center for my company. I hadn’t really dove into it on a micro level until a few days ago.

Setting Up daemontools on CentOS 5

I recently had to setup daemontools on a CentOS system. I had set it up before but it had been a while. So I Google’d around and found very little and what little I did find wasn’t very helpful. So here is a quick and dirty on setting up daemontools. I even included the CentOS fix that I came across to make it compile. There is also a patch version (if you were building an RPM), but I prefer just making the change in this case; it’s much simpler.

Count Instead of Sequence

I use Bash one liners a lot. I think they are an important part of any programmers and sysadmins toolkit. If you can’t write a bash one liner, even a simple iterator, then you really need to learn. I promise it will make your life infinitely more pleasant.

Frequently I find myself writing things that require a loop or an increment of numbers. A good example would be like something that would walk over my web servers and check their uptime, load averages, etc. Using seq, that’s easy. But since Mac OS X doesn’t come with the seq command, I would previously improvise.
