    Automatically Cache Updates To Your OS X Server

    A little while back, I did a little writeup on how the OS X Caching Server caches updates at https://krypted.com//mac-security/how-the-os-x-caching-server-caches-updates/. The goal was to reverse engineer parts of how it worked for a couple of different reasons. The first was to get updates for devices to cache to my caching server prior to 15 people coming in before it’s cached and having caching it down on their own. So here’s a little script I call precache. It’s a little script that can be used to cache available Apple updates into an OS X Server that is running the Caching Service. To use, run the script followed by the name of…

    20 Things To Do In Austin While Attending ACES

    Things to Do In Austin In May Diverse, fun and infused with culture, Austin is the capital of Texas and home to a prosperous community and a wide variety of culture, from the world class cuisine in the many fine restaurants, the growing population of infamous tech companies, the summer festivals and creative atmosphere, to the magnificent country music in what is also referred to as the Live music capital of the world (although Nashville, Athens, and other cities might have some arguing of that point). Here are some great things to do when you visit Austin:  Austin City Limits I grew up seeing acts including Willie Nelson, Little Feat,…

    Scripting The OS X Caching Server To Cache Updates

    The Caching Server in OS X is a little bit of a black box. But, it’s not all that complicated, compared to some things in the IT world. I’d previously written about command line management of the service itself here. When you enable the caching service, the server registers itself as a valid Caching Server. Nearby devices then lookup the closest update server with Apple and register with that update server using a GUID: /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin settings caching:ServerGUID Then, each time the device looks for an update, it does so against http://mesu.apple.com/assets/com_apple_MobileAsset_SoftwareUpdate/com_apple_MobileAsset_SoftwareUpdate.xml using the device model. Noticed this with this line in my proxy logs: "GET http://mesu.apple.com/assets/com_apple_MobileAsset_SoftwareUpdate/com_apple_MobileAsset_SoftwareUpdate.xml HTTP/1.1" 200 - "-"…

    Create Classes In Profile Manager For The Classroom App

    Creating a classroom is a pretty straight forward process in Profile Manager. To do so, open the Profile Manager web interface and click on Classes in the sidebar. For your first class, click Add Class (for future ones, click the plus sign (+). At the New Class screen, click into New Class in the title bar and provide a name for the class. Optionally, provide a description, as well. Click on the Save button to save the class. Then click on the Instructors tab and use the plus sign towards the bottom of the screen and then choose the user or group you’d like to add as the Instructor for the class.…

    Software Update Server Reset Script

    Any time I need to get a bunch of cruft out of Software Update Server on OS X Server, I just reset it real quick. To do so, simply remove /Library/Server/Software Update. But first, it’s important to stop the service, and once removed, set the port back up (which isn’t done automatically), and then start the service (swupdate). As this has become somewhat routine, I made a micro-script of it here.

    My first article in Entrepreneur: Business Lessons Learned From Superheroes

    My first article on Entrepreneur is out! This is a piece on lessons about running a business that I learned from… Superheroes. So continuing the overarching theme of linking business, technology, and what we in those realms are actually interested in! These articles evolve once they go to the publisher, which is fun for me to watch as well. Anyway, I hope you enjoy. As usual, a sample, and a photo (many of these are for my own library, btw). “Batman v Superman” set a record in late March for the biggest superhero movie international opening ever (negative reviews aside, as parodied in the “Sad Affleck” video that’s closing in on 20 million hits as…

    MacDevOps 2016

    MacDevOps 2016: f you’re interested in the scripting side of the Apple world and can make it from June 20th to 21st, this might just be the conference for you. At MacDevOps, you’ll see “Speakers from across North America and Europe will be presenting on a number of topics related to Mac administration and deployment.” This would be things like contributing to open source projects, packaging Django web apps to look like native Mac apps, osquery, Munki security, imagr, autopkg, ansible, git, and jenkins. Basically, automating the things: DevOps. And for Macs. Or Appley things. For now. And… Lots of fun people will be there. including the convergence of friends from…
