Installing Munin on Ubuntu 16.04 is not the hard. Munin is a monitoring system that runs over the network for the local server and remote servers. It monitors all the basics out of the box. We can use it to monitor servers of all types to see what has happened and help find out why stuff broke or started to go slow.

Creating Ubuntu 16.04 Mirror on a Synology Diskstation
I am constantly installing Ubuntu with various configurations. I find having a local Ubuntu 16.04 Mirror on a Synology Diskstation speeds up the installation and updates, making the time spent setting it up well worth while.
Backup your diskstation before doing anything else, just in case.
Test Networking Lab Ubuntu on 16.04
I wanted to create a test networking lab Ubuntu on 16.04 for trying out configurations without having to hack my real LAN about. I decided to use VirtualBox virtual machines as they are freely available and work with Linux and you can also use MS Windows guests. The network in the test networking lab Ubuntu on 16.04 will need to separate from our own normal LAN. VirtualBox provides this out of the box. We simply set the network interfaces to us “Internal Network”. This way only VM’s on the host can see each other.
This post will, quickly, run through how to create a Minimal Server Install using Ubuntu 16.04. It also only takes a short time, taking between 7 to 20 minutes to install depending on your hardware and the number of times you have run through it. I find it an ideal way to try out and learn how to install Ubuntu in various configurations. I also use a virtual machine running on Virtualbox as this allows me to throw it away without messing about with real hardware.
Synology documentation sucks big time! It usually only states the blindingly obvious missing off any useful or helpful information.
This post will run through the harder parts of setting up DNS and DHCP on Synology NAS. It is a little tricky the first time you do this especially if you have not come across bind or bind9 before. It seems a little over the top or just plain weird. You will only really need this if you have some local servers, computers or other devices that need to be accessed.
Updated for DSM 6.0, because Synology buggered about with stuff! This may not work on earlier versions.
