Revision as of 22:45, 8 October 2010

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)

• 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 - 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

• 3 - Setup the cross package

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

• 4 - 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

• 5 - 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

• 6 - 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" | tee -a /etc/sysctl.conf

• 7 - 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

• 8 - Install autofs

mkdir /mada

Get autofs files from another machine

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

• 9 - awk for cadence

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

• 10 - Set the firewall

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

• 11 - 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

• 12 - 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>@mascd12:/etc/krb5.conf /etc/

Copy the ldap certificate

scp <username>@mascd12:/etc/ssl/certs/* /etc/ssl/certs/

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

scp <username>@mascd12:/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>@mascd12:/etc/ldap.conf /etc/ldap.conf
scp <username>@mascd12:/etc/ldap/ldap.conf /etc/ldap/ldap.conf

Now you should be able to execute:

ldapsearch -x LLL

• 15 - 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
+ : 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.

• 14.5 - Restart your computer:

shutdown -r now

• 14.6 - 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.

• 15 - Install NVIDIA Drivers (Please read all instructions before proceeding!)

Open a terminal and type:

sudo su -
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

Login as root, if not already, and rerun the installation

sudo su - 
./NVIDIA-Linux-x86_64-256.53.run

NOTE: You may get several error messages during the installation including "PreInstall Script has failed", Nouveau is causing problems, etc. These are normal, and following all of the instructions will resolve them.

The installation will fail due to the Nouveau drivers, but it will create a script to disable them. Just restart the computer and reclose X, then go through installation again and it should work as expected.

shutdown -r now

Switch to tty1 (CTRL + ALT + F1), and login as root.

service gdm stop
./NVIDIA-Linux-x86_64-256.53.run

NOTE: NVIIDIA Drivers should have installed properly this time. Make sure that you choose to overwrite the xconfig file.

Restart for the changes to take effect properly:

shutdown -r now

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

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

Switch to tty1 (CTRL + ALT + F1), and login with your SOE account.

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

• 18 - 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

Enable 32 bit compilation ln -s /usr/lib32/libstdc++.so.6 /usr/lib32/libstdc++.so

Installing CUDA 3.2 (not complete)

• Download the following from http://developer.nvidia.com/object/cuda_3_2_toolkit_rc.html
  • CUDA Toolkit for Ubuntu Linux 10.04
  • GPU Computing SDK code samples
  • Developer Drivers for Linux (260.24)
