Lab update

Just dropping a quick post to say everything has been running great! A few hiccups, but it's been a learning process!

The base infrastructure of my network includes Linux based virtual machines, all running on Ubuntu server 12.04 LTS. These lovely little virtual machines let me do more on my main rig without tying up resources. Currently for my main, every day virtual machines I'm running:

  • One BIND based DNS server for internal name resolution

  • One Serviio streaming server with a web interface (I can also control this from an app on my phone/tablet - Sweet!)

  • One web server running with a LAMP stack. This currently hosts my mediawiki install where I keep track of any configuration I do for future reference.

  • One server running the Deluge daemon for downloads. Has a 500GB virtual drive dedicated to it. I access this via either web client or desktop client. (Desktop client actually feels completely local)

  • One Minecraft server running Minecraft My Admin. This can be a bit flaky, but I learned that a custom built one was much better than the turnkey appliance I downloaded initally.


I also have two other resource pools dedicated to testing and labbing. In the test pool I'm just playing around with Server 2012 R2 as a home domain controller (Thinking of moving both my DNS and DHCP to it), along with a couple other random virutal machines. In my lab pool, I have a full suite of Server 2012 R2 machines running various features in the same domain. All of the Server 2012 virtual machines run off the file server, which has provided exceptional performance.

As for the hiccups, I ran into some instability once in a while with Backtrack and USB pass through. The host would go completely unresponsive from time to time with nothing in the logs. After moving Backtrack to my desktop and running it with USB pass through in Workstation 9, the instabilities went away completely. There was also the issue with Deluge constantly crashing after downloading for a few minutes, but it ended up being a bad file.

The Minecraft server is another issue flat out. I was running it as a turnkey virtual appliance for a while, as I didn't want to bother with the configuration at that moment. That was until it broke. Luckily I was able to mount the drive in another virtual machine and recover the data. Once the data was recovered, I hand built the next instance of the server, which has so far been a lot more stable. (Issue this morning with an MCMA update, however it was resolved rather quickly by killing and rerunning the process, and accepting the upgrade.)

In the future I have plans on implementing Puppet or Chef, however that won't be for a little while. I hope if I do that I'll be able to document it!
