Currently still testing the distribution, so please report any problems to Ian and Jose!!

0 - Install Ubuntu 10.04 x86_64

NOTE: ONLY if you have trouble with Step 4 of the installation process, the partition selection, open a terminal in the trial mode and run:

sudo dmraid -r -E /dev/sda

NOTE: When prompted for a username, choose one that is NOT your SOE login! For example "ian_local" rather than my SOE login of "ianlee1521". Otherwise you will not be able to login to your computer after you setup LDAP.

NOTE: When prompted for a machine name, enter the name that machine is supposed to be (mascd1, omelette, quiche, etc)

Installation should complete as normal.

Plain Ubuntu Installation

1 - Enable root account

Login to the GUI with your local login, then open a terminal (Applications -> Accessories -> Terminal):

sudo su - 
passwd

Enter your new root password for the machine.

Add your local and SOE logins to the sudoers list:

vim /etc/sudoers

2 - Install NVIDIA Drivers

Blacklist some kernel modules

vim /etc/modprobe.d/blacklist.conf

Add the following lines to the file

blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv

Get rid of any installed NVIDIA drivers:

sudo apt-get --purge remove nvidia-*

Reboot the machine. X11 will not start. Switch to a terminal (CTRL + ALT + F1), and login as root:

wget http://us.download.nvidia.com/XFree86/Linux-x86_64/256.53/NVIDIA-Linux-x86_64-256.53.run
chmod 744 NVIDIA-Linux-x86_64-256.53.run
service gdm stop
./NVIDIA-Linux-x86_64-256.53.run

Reboot the machine and X should start normally. Login at the GUI login as root and open a terminal.

3 - Setup the new repo

apt-get install -y emdebian-archive-keyring
echo -e "\ndeb http://www.emdebian.org/debian/ lenny main" | tee -a /etc/apt/sources.list
apt-get update -y
apt-get dist-upgrade -y

4 - Setup the cross package

apt-get install -y apt-cross dpkg-cross libncurses5-dev

5 - Instal ARM packages

apt-get install -y libc6-armel-cross libc6-dev-armel-cross
apt-get install -y binutils-arm-linux-gnueabi gcc-4.3-arm-linux-gnueabi g++-4.3-arm-linux-gnueabi 
apt-get install -y linux-libc-dev-armel-cross
apt-get install -y uboot-mkimage

6 - Install SPARC packages

apt-get install -y libc6-sparc-cross libc6-dev-sparc-cross
apt-get install -y binutils-sparc-linux-gnu gcc-4.3-sparc-linux-gnu g++-4.3-sparc-linux-gnu
apt-get install -y linux-libc-dev-sparc-cross

7 - Adjust sysctl options

mmap problem for qemu

vim /etc/sysctl.d/10-zeropage.conf

Edit the following value:

vm.mmap_min_addr = 4096

increase (add) the inotify watches in /etc/sysctl.conf

echo -e "\nfs.inotify.max_user_watches = 65535 \nkernel.randomize_va_space = 0" | tee -a /etc/sysctl.conf

8 - Replicate the installation on Master machine (mascd12, dhcp-63-154.cse.ucsc.edu)

ssh <username>@mascd12 dpkg --get-selections > mypackages.txt
dpkg --set-selections < mypackages.txt

"apt-get dselect-upgrade -y" Will give many options and take a long time for the upgrade (about an hour for me).

Select all default options EXCEPT! for ion3: acknowledge the lack of support (non-default option)

apt-get dselect-upgrade -y

MADA Related Stuff

9 - Install autofs

Create mada directory

mkdir /mada

Get autofs files from another machine

scp <username>@mascd12:/etc/auto.* /etc/
ln -s /mada/users /soe
initctl reload autofs

10 - awk for cadence

apt-get install -y ksh csh original-awk
ln -s /usr/bin/awk /bin/awk

11 - Set the firewall

ufw enable
ufw default deny
ufw reject auth
ufw limit ssh/tcp

12 - Get tempcap from another ubuntu machine (mascd1, mascd12, ...)

scp <username>@mascd12:/usr/lib64/libtermcap.so.2.0.8 /usr/lib64/
ln -s /usr/lib64/libtermcap.so.2.0.8 /usr/lib64/libtermcap.so.2

13 - LDAP

Install

apt-get install -y ldap-auth-client libpam-krb5 krb5-user libsasl2-modules-gssapi-mit

Leave the kerberos config entry blank. You will copy it in the next step.

Create /ect/krb5.conf

scp <username>@mascd1:/etc/krb5.conf /etc/

Copy the ldap certificate

scp <username>@mascd1:/etc/ssl/certs/* /etc/ssl/certs/

Create "/etc/auth-client-config/profile.d/krb-ldap-config"

scp <username>@mascd1:/etc/auth-client-config/profile.d/krb-ldap-config /etc/auth-client-config/profile.d/krb-ldap-config
auth-client-config -a -p krb_ldap

Update ldap.conf

scp <username>@mascd1:/etc/ldap.conf /etc/ldap.conf
scp <username>@mascd1:/etc/ldap/ldap.conf /etc/ldap/ldap.conf

Now you should be able to execute:

ldapsearch -x LLL

14 - Lock SOE people out of your machine :)

scp <username>@mascd12:/etc/security/access.conf /etc/security/access.conf

You will need to add your local login to the machine, or you will lock yourself out:

vim /etc/security/access.conf

Go to very bottom of file and add your local user account to the list below root Example of the last lines of my file (Replace "ian_local" with your local login):

+ : root : ALL
+ : nx   : ALL
+ : ian_local : ALL
+ : (masc) : ALL
+ : (vlsi) : ALL
-:ALL :ALL

Now, you should see people with "getent passwd" but, calling "su - cormac" should say "permission denied", but, calling "su - renau" should work.

15 - Since the LDAP has timeouts, setup the local backup

apt-get install nss-updatedb
nss_updatedb ldap
cd /etc/cron.hourly/
scp mada1:/etc/cron.hourly/nss_updatedb-ldap.sh .
scp mada1:/etc/nsswitch.conf /etc

16 - Restart your computer:

shutdown -r now

17 - Login to the GUI with your SOE login information. If you get a prompt asking for an "LDAP Password" this means that you typed your password incorrectly.

18 - Remove old desktop configuration files (KDE / GNOME / browser)

NOTE: Removing ".config" will delete any saved passwords in your browser, but will fix other problems.

Logout of / kill any open X sessions. Switch to tty1 (CTRL + ALT + F1), and login with your SOE account.

rm -rf .config .kde* .gconf* .gnome*

19 - Some Minor Patches for things that don't work properly

Disable apparmor

sudo invoke-rc.d apparmor stop
sudo update-rc.d -f apparmor remove

20 - Add bash as default shell

cd /bin
ln -sf bash sh

21 - Using QEMU and ARM in 32 bit mode. We need to install 32 bit libraries for this (as root).

sudo apt-get install g++-multilib lib32z1 lib32z1-dev lib32ncurses5 lib32ncurses5-dev

22 - Miscellanous Kate and Kwrite text editors

sudo apt-get install kate kwrite emacs22-gtk emacs22

23 - Make sure that there is no file indexing (beagle)

sudo apt-get purge beagle

24 - Add to /etc/crontab to maintain same time (13:13 use any other random time)

echo -e "13 13   * * *   root    /usr/sbin/ntpdate ntp.ucsc.edu" | sudo tee -a /etc/crontab

25 - Add a freenx server to your desktop

sudo add-apt-repository ppa:freenx-team
sudo apt-get update
sudo apt-get install freenx-server

26 - Add sendmail (no external forwarding)

apt-get purge exim4
apt-get install sendmail
cd /etc/mail/
scp mada0:/etc/mail/alias* .
scp mada0:/etc/mail/sendmail.* .
scp mada0:/etc/mail/generi* .
chmod 777 /var/spool/mqueue
/etc/init.d/sendmail restart

Installing CUDA 3.2

You will need sudo access to install CUDA 3.2. It can only be installed on machines with NVIDIA GPUS.

Download the following
- Developer Drivers for Linux (260.24) http://developer.download.nvidia.com/compute/cuda/3_2/drivers/devdriver_3.2_linux_64_260.24.run
- CUDA Toolkit for Ubuntu Linux 10.04 http://developer.download.nvidia.com/compute/cuda/3_2/toolkit/cudatoolkit_3.2.9_linux_64_ubuntu10.04.run

Move these files to your home directory.

Make sure the following kernel modules are blacklisted

sudo vim /etc/modprobe.d/blacklist.conf

If not already present, add the following lines to the file

blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv

Get rid of any installed NVIDIA drivers:

sudo apt-get --purge remove nvidia-*

Reboot the machine. X11 will not start. Switch to a terminal (CTRL + ALT + F1), and login.

Stop X11

sudo service gdm stop

Install the downloaded device driver first.

sudo devdriver_3.2_linux_64_260.24.run

Accept the license agreement.
Install NVIDIA's 32-bit compatibility OpenGL libraries? Answer: YES
Would you like to run the nvidia-xconfig utility to automatically update your X configuration file so that the NVIDIA X driver will be used when you restart X? Answer: YES

Install the CUDA toolkit (nvcc etc. )

sudo cudatoolkit_3.2.9_linux_64_ubuntu10.04.run

Choose default options. CUDA will be installed in the /usr/local/cuda directory. When the installation is complete, you will be asked to make changes to your INCLUDE and LD_LIBRARY_PATH env. variables.

Reboot and login.

OPTIONAL: Download GPU Computing SDK code samples http://developer.download.nvidia.com/compute/cuda/3_2/sdk/gpucomputingsdk_3.2_linux.run. This will be installed in your home directory by default.

Installing grid-engine (server)

Firewall

ufw allow in 6444
ufw allow in 6445

packages

apt-get purge gridengine-exec
apt-get install gridengine-exec gridengine-client

Set SGE master

echo "mada0.cse.ucsc.edu" >/var/lib/gridengine/default/common/act_qmaster

Start daemon (do not wait for the next reboot)

/etc/init.d/gridengine-exec restart
