Yes, Munki’s makecatalogs runs on Linux
You can’t run all of Munki‘s admin tools on Linux, because some of the things the tools use involve Mac-specific tools, which is why even Munki admins who host their Munki servers on a Linux server will use a Mac for things like munkiimport. You can, however, run makecatalogs on Linux, though. Here’s just a…

Let’s Encrypt certificate “expired” even though it’s not?
One of our servers (Ubuntu 18.04 with Nginx) is using Let’s Encrypt‘s certbot to renew its SSL certificate regularly via script. Recently, it reported in web browsers as having an expired certificate. When I ran certbot renew it showed as having the certificate set to expire months from now. Just on a lark, I rebooted…

Getting osTicket to schedule ticket creation from emails
If you go to Admin Panel > Emails > Settings > Incoming Emails, right now (as of release 1.10.4—the latest stable release as of this writing), you’ll see something called Fetch on auto-cron, which isn’t super useful, because it will fetch emails only if an agent is logged into osTicket. There is an external scheduler…

Setting up Nagios on Ubuntu 16.04 (Xenial)
The best guide I found for installing Nagios on Ubuntu 16.04 (Xenial) was How To Install Nagios on Ubuntu 16.04, with only a couple of amendments. First of all, it’s not using the absolute latest version of Nagios or the Nagios plugins. And secondly, it’s missing a command in terms of untarring the downloaded Nagios.…

How to create a bootable Ubuntu USB stick on/for Macs
For some reason (at least as of this writing), the official Ubuntu documentation on creating a bootable USB of Ubuntu for Macs is now recommending using UNetbootin. I haven’t found that to actually work. I dug up a cached copy of the old instructions (which do work), but I wanted to document the old procedure…

Get photos/music off an iPad or iPhone using Ubuntu Linux
Disclaimer These instructions work for iOS 8 (tested on both an iPhone and an iPad) using Ubuntu 14.04 (Trusty) and Ubuntu 15.04 (Vivid). The instructions will still likely work in other versions of iOS and Ubuntu, but your mileage may vary. What’s the problem? If you take pictures with your iPhone or iPad and then…
