Get a copy of Linux, if you don't have one. Ubuntu 11.10 64-bit is recommended.
You're welcome to choose another flavor of Linux if you're willing to be on your own for support.
Ubuntu 11.10 CDs are available in the lab. Leave the CD by the printer in the lab when finished.

How to download and burn an ISO to CD:

Note the IP address (see label) of your machine: 134.197.34.

Install

Press <F12> Boot Options until you hear a beep and select Onboard or USB CD-ROM Drive

Warning: If you are using one of the T3500s your screen will go blank unless you:

Hit <ESC> as soon as you see the Ubuntu splash screen

Hit <F6> and select nomodeset (Press <ESC> to get out of the menu)

Boot the 11.10 CD – double-click “Install Ubuntu 11.10” icon and take all the defaults except the following:

When you get to the Installation Type screen select: “Something Else” to specify partitions manually

• Partitions:
• Delete all Ext 3/4 and Swap partitions (All the partitions below the NTFS partition Windows is loaded on)
• Click on Free Space and Add 3 new logical partitions: (do NOT create a new partition table)
• partition type: ext4 size: 20000 mount point: /
• partition type: ext4 size: 60000 mount point: /home
• partition type: swap size: 5000 (no mount point for swap partitions)
• leave the rest as free space (we need free space for a later project)

Click “Install Now” when done partitioning

Enter what you want for your User Name and Password

Computer name: cselab(n) # Get name from the label on your computer
Pick a different name if it says you name is already taken

Reboot when done

On T3500s add nomodeset to the kernel line in GRUB:

echo "ALL: 127.0.0.1" >> /etc/hosts.allow
echo "sshd: 134.197.40. 134.197.34." >> /etc/hosts.allow

Configure /etc/host, ntp and openssh:
apt-get –y install vim openssh-server ntp
vim /etc/hosts
Change the 127.0.0.1 on the second line to your IP address
134.197.34.x cselab(n) # where x is your IP and n is your machine number
ssh to your hostname (cselabn) to make sure you can login
