This article, the first of an intro to HPC, could also be called, “Centralized Scripting for Workstation Management”, so don’t let the scary HPC title put you off! In reality we can all learn a bit from how an HPC (High Performance Computing) environment is managed to better streamline even the smallest computer setup – after all, more streamlined means more spare time to spend out of the office!

scutil can allow to change a number of OS X settings including the DNS servers.

However it is more than a bit cryptic in it’s use.

You're most likely reading this because you're as sick as I am of seeingmalloc warnings when trying to start up MySQL in Mac OS X on your Xservewith 8GB of RAM and you've configured MySQL to use more than 4GB. If I've got 8GB of RAM, why can't I use more than 4GB in MySQL? Well, just because you've got 64-bit processors and an OS with64-bit support doesn't mean that your applications run in 64-bit. Youhave to explicitly build your application for the 'ppc64' architecturein order to take advantage of 64-bit addressing and use more than 4GBof RAM. Here's how you build MySQL as a 64-bit application.

A quick overview of doing redirects from non-ssl to ssl websites.

Ed. Note: While you should be able to do this in the 10.4 web GUI, you were unable do this in earlier versions of OS X Server. That’s where this comes in handy, although this method should work for all version of OS X, or Apache on any system for that matter.

Everything you should need to know about the initial setup of Mail.

Getting all the Xsan pieces straight in your head

When Xsan came out, it was the first time that the average Apple System Administrator had seen a Storage Area Network (SAN), and as a result, there’s a lot of questions about how to best deal the very fundamentals of an Xsan setup. Here we’re hoping to cover a lot of the questions that are being asked, and help you on your way to the healthiest Xsan environment you could get.

I have to admit, when I first heard that Apple was adding ACLs to the next version of OS X, I got a pretty nasty lump in my throat and ordered another pint of ale. I was first introduced to ACLs in DFS on AIX and I still have nightmares and flashbacks of files which can’t be deleted by root and will forever remain on the disk until the next newfs. After reading through Apple’s new File Services manual however, I’ve learned to stop fearing and start loving the ACL. Apple’s implementation of ACLs on Darwin is actually very intuitive and makes a whole lot of sense.

I noticed that squirelspell is not working on Mac OS X Server. I found an outdated article at this site. Using that article and searching internet, I compiled this article. I hope this will be useful to many OS X Server administrators.
