## Enter the Gateway of "10.20.3.1"
## Enter the Nameservers "10.20.70.16 10.20.70.17"
# Hostname: Set the FQDN of the machine as the hostname. Ex: clarke.cs.transy.edu
# Select "Eastern" time zone

=== Partitioning (Single Disk) ===
# Select the "Manual" method
# Use the arrow keys to highlight the disk (usually sda) and press enter
# Confirm the dialog to create a new empty partition table.
# Select the "FREE SPACE" and press enter.
# Create the following partitions:
## (TotalSpace - 2 GB), primary, mountpoint: /, use as: ext3, options: bootable
## 2 GB, logical, use as: swap
# Select "Finish Partitioning" and write the changes to disk

=== Partitioning (Software RAID 1) ===
# Select the "Manual" method
# Use the arrow keys to highlight each disk and press enter
# Confirm the dialog to create a new empty partition table on both drives.
# Select the "FREE SPACE" on each drive and create a TotalSize - 2gb primary partition
# Select Use as: Physical volume for RAID
# Select "Done setting up partition"
# Select the "FREE SPACE" below the partition you just created
# Use the remaining space on that first drive for another primary partition
# Select Use as: Physical volume for RAID
# REPEAT for second drive
# Select "Configure software RAID" at the top
# Confirm the changes (which have to be committed before configuring RAID)
# Select "Create MD Device"
# Select "RAID1"
# Number of active devices: 2
# Number of spare devices: 0
# Select /dev/sda1 and /dev/sdb1 then continue
# Create a second MD Device with /dev/sda2 and /dev/sdb2 just as the previous 5 steps
# Select "Finish"
# In the partitioner, select the first RAID device and Use as: ext3, Mount point: /
# Lastly, select the second RAID device and Use as: swap area then select "Finish partitioning and write changes" to disk at the bottom.


=== Finish Up ===
# Full name for new user: lab
# Username for your account: lab
# Password: lab (this user will be deleted later)
# Verify Password
# Leave the HTTP proxy box empty and select "Continue"
# Note: If it freezes "Scanning the mirror" unplug and replug the ethernet cable once.
# Software to install: Select "OpenSSH server" and select "Continue"
# The system will finish configuring and ask you to "Continue" before it reboots.

== Configuration (via SSH) ==
* This section is done via SSH as a convenience for installing multiple systems.. but can be done from the keyboard.

# ssh lab@HOST.cs.transy.edu
# sudo su -
# passwd root (set the current root password)
# exit
# exit

# ssh root@HOST.cs.transy.edu
# userdel lab
# rm -rf /home/lab
# Transfer or enter the following into /etc/apt/sources.list:

# apt-get update
# apt-get upgrade
# apt-get dist-upgrade

=== Switch to Generic Kernel ===
* Since the Ubuntu kernels have virtualization built in which is not compatible with nvidia drivers. Even after this is resolved, it is still nice to run the official kernel.org generic sources. Very compatible.
# uname -a
# apt-get install linux-image-generic linux-doc-2.6.XX linux-source-2.6.XX (replace XX with the sub-version output from uname)
# apt-get remove linux-image-2.6.XX-YY-server --purge (again XX from uname)

* REBOOT!

# ssh root@HOST.cs.transy.edu

=== Configuring LDAP Authentication ===

* First we need to get GDM (the graphical login) and its dependencies installed so..
# apt-get install gdm

# apt-get install auth-client-config libpam-ldap libnss-ldap ldap-auth-client ldap-auth-config
## LDAP server Uniform Resource Identifier: ldap://10.20.3.8
## Distinguished name of the search base: dc=cs,dc=transy,dc=edu
## LDAP version to use: 3
## Make local root Database admin: NO
## Does the LDAP database require login?: NO

# Edit /etc/ldap.conf and change the following values:
## host 10.20.3.8
## base dc=cs,dc=transy,dc=edu
## uri ldap://10.20.3.8

# Edit /etc/ldap/ldap.conf
## BASE dc=cs,dc=transy,dc=edu
## URI ldap://10.20.3.8

# Edit /etc/auth-client-config/profile.d/transy

# mkdir /classes
# mkdir /labdata
# Edit /etc/fstab
<code><pre>
