• Create the following partitions:
  • (All of the computer's space except 2 GB), primary, mountpoint: /, use as: ext3, options: bootable
  • 2 GB, logical, use as: swap
• Select "Finish Partitioning" and write the changes to disk

For Systems where RAID has been set up

• Select the "Manual" method
• Use the arrow keys to highlight the large RAID disk
• Change type to Ext3
• Mount Point is /
• Format the drive.
• Make RAID 0 bootable
• Check to make sure the small RAID disk is set to swap.

For New Systems

• 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 (at the Beginning)
• 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 (at the Beginning)
• Select Use as: Physical volume for RAID

• 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

• Select "No configuration" for th email server.
• Full name for new user: lab
• Username for your account: lab
• Password: qazzaq (this user will be deleted later)

Configuration

• This section is done via SSH as a convenience for installing multiple systems.. but can be done from the keyboard. Note that if the system has been SSHed before the install of the new system, the SSH will report that there is a risk of a man in the middle attack. If this happens:
• Edit /root/.ssh/known_hosts
• Delete the line that SSH is complaining about (listed in the error message).

• ssh lab@ipaddress
• sudo su -
• passwd root (set the current root password)
• exit
• exit

• ssh root@ipaddress
• userdel lab
• rm -rf /home/lab
• Add the following to /etc/apt/sources.list:
• 64-bit:

deb http://babbage.cs.transy.edu/ubuntu-amd64/ lucid main restricted universe multiverse
deb http://babbage.cs.transy.edu/ubuntu-amd64/ lucid-updates main restricted universe multiverse

#deb http://babbage.cs.transy.edu/ubuntu-amd64/ lucid-backports main restricted universe multiverse
#deb http://babbage.cs.transy.edu/ubuntu-amd64/ lucid-proposed main restricted universe multiverse

• 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.
• ls /boot
• apt-get install linux-image-generic linux-doc linux-source-2.6.XX (replace XX with the LATEST kernel sub-version output from ls /boot)
• apt-get remove linux-image-2.6.XX-YY-server --purge (again XX from ls /boot)

• 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
  • bind_policy soft

• 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

[transy]
nss_passwd=passwd: ldap files
nss_group=group: ldap files

        session    required     pam_unix.so
        session    optional     pam_ldap.so

• auth-client-config -a -p transy
• Add the following line near the very top of /etc/pam.d/gdm AND /etc/pam.d/login

auth    optional        pam_group.so

• Add the following to the BOTTOM of /etc/security/group.conf:

# This will force all users that logon into these groups
login;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip
kdm;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip,video
gdm;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip,video

• Test LDAP authentication - if "id USERNAME" returns with info about the user... all is good.

root@clarke:~# id kmoorman
uid=1129(kmoorman) gid=110(faculty) groups=110(faculty),800(camp),2100(linux)
