== How to install MIRC-Zn on Ubuntu Linux ==
 
* Download the script
 
wget http://timphillips.net/mirc/install-MIRC-Zn.txt
 
* Make it executable
 
mv ./install-MIRC-Zn.txt ./install-MIRC-Zn
 
chmod 777 ./install-MIRC-Zn
 
* Run the script
 
./install-MIRC-Zn
 
* Point your browser to the machine you just installed it on and MIRC should be up and running.
 
* This script will also upgrade a previous "Tim Phillips" installation of MIRC-Zn so it can be used again when the RSNA code is updated.
 
  
==What the script does==
 
 
* Checks you're running it as root or using sudo.
 
* Stops the MIRC-Zn service if its running.
 
* Checks which chipset you're running.
 
* Enables the ubuntu partner repo (to get Oracle Java).
 
* Answers the Java installation questions in advance.
 
* Installs SunJava and a few other necessary applications.
 
* Downloads the appropriate JAI ImageIO files installs JAI ImageIO.
 
* Downloads the latest version of MIRC-Zn.
 
* Writes an upstart script (so that CTP/MIRC will be run as a service automatically).
 
* Installs RSNA MIRC.

==Choosing between Ubuntu Desktop and Ubuntu Server==
 
 
* Ubuntu Desktop
 
** Easier (very easy) if you're new to Linux.
 
** May be very slightly slower but on modern hardware you are unlikely to notice the difference.
 
* Ubuntu Server
 
** Makes more sense - MIRC is a web service after all.
 
** Will be leaner and faster.
 
** Can run on a headless server or virtual machine.
 
** [http://turnkeylinux.org TurnkeyLinux] is a very good Ubuntu install for this purpose.
