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.

Installing LDAP on Ubuntu 18.04
This post will run through Installing LDAP on Ubuntu 18.04. Allowing you to authenticate users via LDAP. As well as setting up thier Linux groups.

Changing the SWAP file Swapiness on Ubuntu 14.04
I have been asked several times about reducing the “swapiness” on a Linux machine to make the machine more responsive. So here is a post on how to do that. Remember just because you can does not make it a good thing to do.
If the machine has 8GB or more RAM turn down the swapiness. That is, if you do not want the system using swap until only 10-15% of RAM is left unused. Then this is the post for you.
Setting up NTP on Ubuntu 14.04
This is a really quick post, as most Linux (or M$ Windows) installations will use/need an NTP server to keep the time in sync with other machines on the LAN.
Update and Install
As always, start with an up to date install. Installing the software is just two packages the server, ntp, and some utilities, ntpdate.
sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ntp ntpdate
Recovering from a RAID1 disk failure on Ubuntu 14.04
This is the second part of my posts on using RAID1 on Ubuntu 14.04, if you missed the first part see it here Installing Ubuntu 14.04 on RAID 1 and LVM
So your shiny RAID1 array lost a disk. DO NOT PANIC.
I’ll say that again, as you probably missed it in your panic.
DO NOT PANIC.
Installing Ubuntu 14.04 on RAID 1 and LVM
So you want an Ubuntu server machine running with RAID1 for reliability and LVM for flexibility.
TIP: Play around with this on a virtual machine. It only takes 10 minutes for a new install.
I used a virtualbox guest. I created a test machine: 2CPUs, 2048MB RAM, 2 x 25Gb Hard disk.
Installing AWstats on Ubuntu 14.04 LTS
If you want to see loads of stats for your web site try installing awstats.
Install
Installing the software and some packages necessary for the geo and net IP location stats.

Joining an Ubuntu Machine to Samba with Winbind
This is the third part of a series of howtos showing how to setup and use Samba4 as a drop in for MS Active Directory Server. The first part Samba4 AD DC on Ubuntu 14.04 is here. The second part in this series take a look at Administering AD DC via Windows.
In this part we will connect an Ubuntu 14.04 machine to the domain and then login with users configured with Active Directory.
Installing a Mailserver on Ubuntu 14.04 LTS Part 2
In this part we will be adding to the mail server created in Installing A Mailserver on Ubuntu 14.04 LTS Part 1, in this part we will be building on that and adding anti-virus and anti-spam software and a tool to greylist emails to cut down on the work our server has to do. This will be added to postfix via amavis-new.
The server called mailserver will end up running the following servers and services. Once all the parts of this series posts are completed.
