I run Ubuntu 14.04 LTS servers on Hyper-V. If you do a fairly routine install you will end up with an anemic ~250 MB boot partition. The boot partition (located at /boot) stores your Linux Kernel and everything the system needs to boot. I am sure you could have guessed that. Next, if you have […]

This lovely item came across my feed today and I realized there is so much that I do poorly when it comes to shell scripting it is absurd 🙁 https://dev.to/thiht/shell-scripts-matter Anyhow I am extremely thankful for this long and detailed post and wanted to pass it along to my readership. I also wanted to crowd-source […]

A little over six months ago I started researching the quickly emerging world of “Hyper-converged” infrastructure as a new IT ethos to take my company’s IT operations into the next decade of application and data hosting. I was first introduced to the idea when I attended a webinar from Simplivity, one of the leading companies […]

I have written articles on how to start using RealmD and SSSD for integrating ubuntu into a windows network. However, prior to that I wrote an article on using PBIS. RealmD and SSSD is, by far, the superior method IMHO and experience, so for all of those folks that want to switch, you probably want […]

A lot of my bash scripting experience has been, in one sense, relatively simple. I have several scripts that span several hundred lines and do fairly complex things across multiple systems. From that perspective they aren’t necessarily simple. However it wasn’t until recently that I had to really starting thinking about managing when scripts run […]

I am working on a project where I need to generate a random value and assign it to a variable… Initially I was doing this: var=$(date +%s | sha512sum | base64 | head -c 12 ; echo) Which was okay until I started executing my script more than once in a short period of time. […]

This is going to be very short and sweet as it is primarily just a note to self. I stuggled with getting outbound mail delivery working for some time and finally got it all figured out. Using Exim4 for mail sending I did the following:

I had a VM using RAW storage format on a ZFS storage object. I needed to delete the RAW hard drive files but couldn’t find them and the “remove” button was greyed out. One post mentioned using “qm rescan” which then allowed the poster to use the remove button but that didn’t work for me. […]

For this tutorial I will be walking through how to use a tool called Realmd to connect an Ubuntu Server or Ubuntu Desktop system to a Windows Active Directory Domain. In the past I wrote an article talking about how to use Powerbroker Identity Services to do the same thing, but the scope of the […]

I have a limited number of IPv4 addresses available to me on my servers. So I am really frugal with how I assign them. Whenever possible, my preference is to use NAT off of the main Proxmox IP. However I struggled to get this setup while also using the built-in Proxmox firewall that comes in […]

If you run a custom theme for your Owncloud distribution, one of the things you know is that whenever you run an update of your Owncloud server it will automatically disable your theme as part of the update process. This is to keep things from blowing up in the event you have made a modification […]

One of the things I like having is a remote system I can access and work on from anywhere. In the past this has meant using either a dedicated server (expensive) or VPS (which is just a VM… too slow). With Proxmox, I figured I had the option of using a container, which would mean […]

If you load Proxmox 4.0 from OVH or any of their affiliates you end up with a partition scheme that gives you one big logical volume for data that is formatted to EXT3. That will work but it isn’t desirable. Starting with Proxmox 3.4, support for the ZFS filesystem was added. ZFS is more than […]

On Thursday I released an article detailing how to get Proxmox setup and also how to configure networking with IPv6. However that article got long and I just said I would address the firewall in the future. Well, that’s today because I need to get the configuration stuff written down before I forget. In addition […]

After beating my head against the wall over the course of many hours I have finally figured out how to get Proxmox working quite well on my cheap KimSufi server… with IPv6. The goal of this article is to document (with varying levels of detail) how to go from a fresh KimSufi, OVH, or SoYouStart […]
