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.
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.
If you want to see loads of stats for your web site try installing awstats.
Installing the software and some packages necessary for the geo and net IP location stats.
sudo apt-get install awstats libgeo-ipfree-perl libnet-ip-perl
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.
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.
I wrote this HOWTO as record of what I did to get my own mail server up and running. I can now and in the future follow these steps again and rebuild my own mail server. I hope it is of use to others too.
This is the second part of a series of howtos showing one way to set up and use Samba4 as a drop in for MS Active Directory Server. The first part Samba4 AD DC on Ubuntu 14.04 is here
Let’s start by adding a small change to the Samba configuration on the AD, lab-addc1. Edit /etc/samba/smb.conf adding the following lines to the [globals] section.
Samba 4 is a good bit of software. If only that last few tweaks could be done to finish it and the documentation off it would be great software. I have found lot of ways to set up Samba4 as a AD DC most of which fail to work only this one series of steps worked. Samba4 configuration is really really flaky! The official Samba documentation is getting better and beginning to cover some of the configuration pitfalls.
For this how to we are building on some of my other howtos.
I no longer use the crippled PBIS software, I use the native Linux software which gives far better functionality.

This was 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 a Linux machine to the domain and then login with users configured with Active Directory. Therefore domain users will always have the same UID and GIDs regardless of the machine they log into.

To create desktops I used my normal install method, starting with a minimal server and then adding MATE and other packages as required.
The Network File System (NFS) was developed to allow machines to mount a disk partition on a remote machine as if it were a local disk. It allows for fast, seamless sharing of files across a network.
