== How to Upgrade Versions of Edubuntu ==
'''NOTE: This WIKI assumes that you are using a 64-bit architecture.'''
An Edubuntu installation DVD (version 10.10) should be located in the the same location as the LTSP server.
Edubuntu is covered under GPL (GNU Public License), and users are allowed to download, burn and use copies for free without violating copyright laws.
Here is a direct link to download alternative CD install of Edubuntu: [ [ftp://ubuntu.arcticnetwork.ca/pub/ubuntu/releases/ ftp://ubuntu.arcticnetwork.ca/pub/ubuntu/releases/] ] A link to the Edubuntu website(For additional installation information): [ [http://edubuntu.org/ http://edubuntu.org/] ]
=== Steps to Perform a Fresh Install ===
These steps assume that you have <u>'''burned '''</u> the current version of Edubuntu from the above linkslink...
'''Steps to Perform Fresh Install:'''
# Make certain computer system is '''connected''' to the Internet, and peripherals. You should have 2 NIC cards (one to Internet connection, other to switch and to the thin clients).# Make certain that Edubuntu installation DVD CD is placed in the CD/DVD drive, and '''boot-up the machine'''.<br />'''Note:''' The current server is configured to boot-up from the CD/DVD drive. If you are installing on a new system, you need to have system boot-up from CD/DVD drive (either by selecting BOOT menu, or configuring BIOS settings).
# Upon boot-up, select '''"Check (test) for errors"''' to make certain there were no errors during the downloading or burning process.
# If the error checking process was successful, then '''reboot the system'''.
# Upon re-boot, then select Install as opposed to running the Live system.
# You basically follow the install procedure, but I will include subtle areas and recommended settings:
:# '''Select "Third Party Applications"''' in one of the initial installation screen.:# '''Select the LTSP option. Make certain that the eth0 interface is connected. '''. LTSP 1) will use the next available network interface (i.e. eth1) to connect to the switch that will, in turn, connect to the workstations (thin clients).:# '''I would recommend an advanced manual partitioning if you have more than one hard disk'''. The current system has two hard disk drives. The first drive is the main system under the mount-point called "/" and the second hard drive has the mount-point called /backup for backing up the system. By correctly specifying these mount-points at this point will allow the system to identify and use these directories when the system is in use. Here are the recommended settings:<br /><ul><li><span style="color:blue;font-weight:bold">Hard drive A</span> (/dev/sda): '''Add swap partition''' (double size for RAM size), '''add remaining partition''' as file-system called '''ext4''' with the mount-point called: '''/'''</li><li><span style="color:blue;font-weight:bold">Hard drive B</span> (/dev/sdb): '''Add entire file-system''' called '''ext4''' with the mount-point called: '''/backup'''</li></ul><br />:# '''Create an administrator account''' (do NOT use the username "admin" (that name is already taken) ). You should keep consistent with usernames on the other computer server in case servers need to be "swapped".
When the installation process has completed, '''remove the installation DVDCD''', and then '''re-boot the computer'''.
Steps:
<ol> <li>Check to see if your server connects to the Internet.</li> <li>Log into "super-user" (eg. issue command '''sudo su''' , and enter your login password)</li> <li>Edit an existing file called "interfaces" by issuing the command: '''vi /etc/network/interfaces'''</li> <li>If necessary, add the text displayed in bold below:<pre># xThis file describes the network interfaces available on your system# and how to activate them.
