Installation[edit]

NONE OF THIS IS VALID YET!!!!!

You will be using the Ubuntu 18.04.3 Server install disc.

WARNING: The pre-packaged installer does not handle RAID well. GParted does. If partitioning is necessary, try it on live and use GParted to partition prior to installing using the below steps.

1. Select "English"

2. Select "Install Ubuntu Server"

3. Select obvious choices

4. When network setup comes, select manual

  a.  subnet 10.20.3.0/24
  b.  ip     whatever
  c.  gateway 10.20.3.1
  d.  nameservers 10.20.70.16, 10.20.70.17

5. When you are to set up the disks.

  a.  We use RAID 1 (mirror)
  b.  Make a partition on the first drive to be all the space - 85 gigs, leave unformatted
  c.  Partition second drive to be same, unformatted
  d.  Now, on the first, add a 75 gig partition /boot and ext4
  e.  On first, add remaining space to swap partition
  f.  Setup RAID 1 using the two partions from steps b, c
  g.  Format ext4 and set to /

6. Your name: Lab - Pick a username: lab - Password: qazzaq - Do not encrypt home folder.

Restart now.

Configuration[edit]

Setting up root SSH[edit]

- sudo vi /etc/ssh/sshd_config

- change PermitRootLogin yes

- sudo service ssh restart


Removing the 'lab' generic account and changing root password[edit]

- sudo passwd

- exit

- from a different machine, ssh root@ipaddress

- userdel lab

- rm -rf /home/lab

Update / Upgrade[edit]

  • apt-get update
  • apt-get upgrade
  • apt-get dist-upgrade

LDAP / LightDM[edit]

  • apt-get install aptitude lightdm ubuntu-desktop kubuntu-desktop plasma-desktop
  • select lightdm
  • 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 / check the following values:
    • host 10.20.3.8
    • base dc=cs,dc=transy,dc=edu (should be set already)
    • uri ldap://10.20.3.8 (should be set already)
    • 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

        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/lightdm 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
lightdm;*;*;Al0000-2400;cdrom,floppy,plugdev,audio,dip,video
  • Test LDAP authentication - if "id USERNAME" returns with info about the user... all is good. (Maybe)
root@clarke:~# id kmoorman
uid=1129(kmoorman) gid=110(faculty) groups=110(faculty),800(camp),2100(linux)
  • Make sure you can log-in via KDM! See Potential Pitfalls.

Filesystems[edit]

  • apt-get install nfs-common
  • mkdir /classes
  • mkdir /labdata
  • Edit /etc/fstab

Add:


# 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
  • Log-in to Babbage
  • edit /etc/exports
  • exportfs -a
  • exit
  • ssh root@IP
  • mount -a
  • Ensure the NFS filesystems loaded with "ls /home" "ls /classes" "ls /labdata"
