2. sudo su -
3. passwd root (set the current root password)
4. exit

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

1. apt-get update
2. apt-get upgrade
3. 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.

1. uname -a
2. 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)
3. apt-get remove linux-image-2.6.XX-YY-server --purge (again XX from uname)

• REBOOT!

1. ssh root@HOST.cs.transy.edu

Configuring LDAP Authentication

• First we need to get GDM (the graphical login) and its dependencies installed so..

1. apt-get install gdm

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

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

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

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

[openldap]
nss_passwd=passwd: ldap files
nss_group=group: ldap files
nss_shadow=shadow: ldap files
pam_auth=auth       required     pam_env.so
        auth       sufficient   pam_unix.so likeauth nullok
        auth       sufficient   pam_ldap.so use_first_pass
        auth       required     pam_deny.so
pam_account=account    sufficient   pam_unix.so
        account    sufficient   pam_ldap.so
        account    required     pam_deny.so

        password   sufficient   pam_ldap.so use_first_pass
        password   required     pam_deny.so
pam_session=session    required     pam_limits.so
        session    required     pam_unix.so
        session    optional     pam_ldap.so

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

auth    optional        pam_group.so

1. 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

1. 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)

Filesystems

1. apt-get install nfs-common
2. mkdir /classes
3. mkdir /labdata
4. Edit /etc/fstab

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda1       /               ext3    relatime,errors=remount-ro 0       1
/dev/sda5       none            swap    sw              0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

# NFS Filesystems
10.20.3.8:/data/exportfs/home           /home           nfs     defaults,rw
10.20.3.8:/data/exportfs/classes        /classes        nfs     defaults,rw
10.20.3.8:/data/exportfs/labdata        /labdata        nfs     defaults,rw

1. mount -a
2. Ensure the NFS filesystems loaded with "ls /home" "ls /classes" "ls /labdata"
