Clear message

This page is intended as a guide to set up UCC machines in some sort of standard way. Please update this if you find any problems when installing things (especially if using newer versions than described here).

Steps marked with <!> require a wheel member, anything else can be done by a winadmin.

Before you start

Steps to do before installation

  • <!> Add forward and reverse DNS entries for the machine.

  • <!> Add the machine to DHCP.

  • <!> Make sure all licenses required are on hand (see /home/wheel/docs/software-license/ on a user server)

Steps to do after

  • Check everything works as expected
  • Email tech@ucc.asn.au with a summary of what was set up/re-installed

Dualboot Machines

These instructions relate to Dualbooting Windows 10 and Linux Mint. If installing a dualboot machine, always install Windows first where possible.

  1. Install Windows following the steps below. Make note of the following:
  2. Depending on the size of the disk, try to reserve up to 500GB or more for Windows.
  3. Linux works fine on anything down to about 100GB but 200GB+ is preferable.
  4. to be completed...

Windows 10

All new Windows machines in UCC should be installed with Windows 10 by default. Previous versions are deprecated.

  1. Find a Windows install disk or make a new one. Make sure you select the Professional edition.
  2. Plug in the install disk and boot from it.
    • Select the US keyboard layout and Australian time/date format.
    • Agree to the license terms etc.
  3. Partition the disks.
    • Delete all existing partitions (if any) on the designated install disk.
    • Select the empty space and click "New" to create a new partition. Enter the desired size or use the whole disk (if not doing dualboot).
  4. Create a dummy user account (call it something like accmurph)

  5. Finish the installer. Once it has rebooted into the new Windows system and you have logged in you can continue.
  6. Install software.
    • Software in this list should either be free to download and install, or something that the UCC has a license for.
    • Open Powershell as Administrator and run the following:

      Set-ExecutionPolicy Bypass; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
      
      choco install -y googlechrome firefox flashplayerplugin  microsoftsecurityessentials keepass.install notepadplusplus.install 7zip.install discord javaruntime vlc chocolateygui opera foxitreader hwmonitor paint.net gimp inkscape adobereader libreoffice winscp.install putty miktex texstudio windirstat lyx
    • Install Steam and Battle.net to the games drive (if any).

    • Install the ocsinventory agent from https://www.ocsinventory-ng.org/en/.

      • This software maintains a registry of all our hardware and is used to determine which machines need upgrading. The server to point it at is https://ocsinventory.ucc.asn.au/ocsinventory and turn off SSL cert verification. No auth is required.

  7. Configure the system for the UCC network. (type any commands below into the Administrator Powershell window you just opened)

    • Delete the dummy user created during install, enable the local Administrator account and set the password:

      net user accmurph /delete
      net user Administrator /active:yes
      net user Administrator <Clubroom Password>
    • Join the machine to the domain UCCDOMAYNE as described in ActiveDirectory#Windows.

    • REBOOT.

    • You may need to manually set the time if it is out of sync, run Command Prompt (not powershell!) as administrator and use the command time HH:MM:SS

    • Force update group policy on the machine (now in the admin Command Prompt window):

      gpupdate /force
      • Once Group Policy has been successfully applied (or before the machine is joined to the domain at all) you can force an NTP time sync with w32tm /resync /force

    • Add static route for 130.95.13.0/26: (This prevents a VPN connection from trying to steal the default route to users home directories.)

      route add -p 130.95.13.0 MASK 255.255.255.192 130.95.13.65
    • Enable pings (alternatively, follow this guide):

  8. netsh firewall set icmpsetting 8 enable
  9. Add the UCC printer blacklight and set it as the default.

Linux Servers

  • At installation:
    • Avoid setting package sources to the UWA mirror as they are frequently out of date. AARNET seems to be the most reliable mirror at this stage
    • Beware of copying the apt_sources list from another server without copying the apt_preferences file too. You might suddenly find yourself with much newer versions of packages than you want.
    • The UCC standard install has all volumes in LVM on md raid. Generally var and home are put on a separate logical volume to root. You had better have a good reason if you're not following this guideline!
  • Add a root user and nuke the initial unprivileged user:
    • That's as simple as running passwd as a super user, re-logging in as root and running deluser on the original user

  • If the machine has an SSD (or several thereof), ensure that TRIM (aka discard) is enabled at all layers (lvm and disk layer)
  • Set up DNS on Mooneye:

    • Add an entry to /etc/bind/domains/primary/ucc.machines then close the file and run zonemake.py in the same directory
    • If zonemake has errors, go back and fix them before proceeding!
    • Use rndc reload to get bind to reload the zone files

  • Set up DHCP on Murasoi:

    • Add the ethernet (MAC) address /etc/dhcp/dhcpd.conf
    • Restart the DHCP server with service isc-dhcp-server restart

  • Set up NFS:
    • Only do this once you have DNS set up and working properly
    • Add the machine to the /etc/exports files on the appropriate servers (Motsugo for /home, Molmol (or just host "away") for /away and nortel+onetel for /services). Reload the server config with exportfs -r (Linux) or service mountd reload (FreeBSD)

    • Remember that only machines on the machine room subnet and physically within the machine room should mount /home while pretty much every machine should mount /away
    • Add the fstab line (copy off Motsugo or something)

    • mount -av and hope

  • Configure the SSH server:
    • Copy the SSH banner (usually in /etc/issue.net) from another server and modify it to suit
    • Ensure the correct banner file is set in /etc/ssh/sshd_config
    • Enable root ssh logins and X11 forwarding in /etc/ssh/sshd_config
    • Restart the SSH server and confirm all working
  • Add the UCC root SSH keys:
    • Add the hostname to /home/wheel/bin/uccroot/push.sh (this will add wheel keys to the machine when the script is run)
    • For adding non-wheelians to certain machines, add their public key to the <machine name>-extra in that same folder

    • Start an ssh-agent using eval `ssh-agent` and authenticate your root key using ssh-add ~<username>/.ssh/id_rsa, then run the updated push.sh script

  • Setup Active Directory. Follow the instructions at ActiveDirectory

  • Install dispense: Go to /home/wheel/tpg/gitclones/opendispense2, run make -C src/client clean all and copy dispense to /usr/local/bin on the target server.

  • Install postfix, set the mail host to mailhost.ucc.gu.uwa.edu.au

  • Packages to install:

  • alpine apache2 biff finger fish joe ladvd logwatch molly-guard mosh ncurses-term ocsinventory-agent openbsd-inetd rkhunter rssh screen subversion sudo strace sxid tig tmux tshark vim zsh 
  • For file servers, you should also install:
  • acl clamav iotop nfs-common nfs-kernel-server
  • Copy rkhunter.conf, mailname from another server
  • Install the UCC motd system on machines which mount /home:
    • Add the following line to /etc/inetd.conf:
    • motda   stream  tcp     nowait  root    /home/wheel/bin/motd.update.sh motda
    • Also add the following line to /etc/services (keeping things in order!):
    • motda           377/tcp                        # UCC MOTD update
    • Finally, run vimotd as root on mussel, add the appropriate information and save the file (which then triggers a global motd push to all servers)
  • Add the following line to the bottom of /etc/rsyslog.conf to enable central logging
  • *.* @130.95.13.1

Linux Desktops

Mint with cinnamon is the agreed SOE - don't install other operating systems or distros.

  • Only install Linux Mint x64 Cinnamon
    • Do NOT install Mint KDE, Mint LXDE or Mint Mate

    • Do NOT install 32-bit Mint

    • Do NOT install Mint Debian - we want Mint built from Ubuntu

    • These instructions work for Linux Mint up to and including Mint 18.3. Mint 19 can and has been installed (eg. on Porcupine and Cobra) but requires realmd to get AD working properly. This should be updated at some point.

  • Add a root user and nuke the initial unprivileged user
  • Set up Active Directory

  • Ensure wheel group and sprocket group have sudo permission sudo visudo

  • %wheel ALL=(ALL:ALL) ALL
    %sprocket ALL=(ALL:ALL) ALL
  • Modify /etc/fstab to mount /away

Something like this (differs with distro):

  • # Mint 17
    away.ucc.gu.uwa.edu.au:/space/away/home     /home   nfs     nfsvers=3,auto,rw,tcp,nosuid,nodev,rsize=8169,wsize=8169,soft   0       0
    # Mint 18
    # Note that in Mint 18.3 this line needs to be ABOVE the line that mounts swap, otherwise nfs fails to automount
    away.ucc.gu.uwa.edu.au:/space/away/home     /home   nfs     nfsvers=3,auto,rw,tcp,nosuid,nodev,rsize=8169,wsize=8169,soft,x-systemd.device-timeout=10,x-systemd-requires=network.target      0       1
  • Add the following lines to /etc/network/interfaces. If you don't do this, network manager takes over the interface and nfs shares don't correctly mount at boot:
  • auto eth0
    allow-hotplug eth0
    iface eth0 inet dhcp
    • In Mint 19 and above, the default network names are predictable and replace eth0 with the appropriate interface name (something like enp31s0).

  • (MINT 18*,19) Create /etc/systemd/network/<ifname>.network and insert the following

  • [Match]
    Name=<ifname>
    
    [Network]
    DHCP=ipv4
  • (MINT 18*,19) Run
  • systemctl enable systemd-resolved.service
    systemctl enable systemd-networkd.service
    systemctl start systemd-resolved.service
    systemctl start systemd-networkd.service
  • Install ssh and nfs packages
  • nfs-common openssh-server
  • Add the UCC root SSH keys: add the hostname to /home/wheel/bin/uccroot/push.sh, then run that script. Ensure the following packages are installed:

  • adobe-flashplugin arduino blender build-essential cvs chromium-browser eagle eclipse fish freeglut3-dev geeqie gimp glew-utils gnucash gtk2-engines-oxygen hugin inkscape jhead keepassxc ladvd libglew-dev libglew1.10 libreoffice locate mplayer nasm nfs-common nslcd ocsinventory-agent openjdk-7-jdk openssh-server pepperflashplugin-nonfree pidgin python remmina remmina-plugin-rdp rdesktop rssh subversion thunderbird tig vim-gtk vlc zsh
  • The server for ocs inventory is ocsinventory.ucc.gu.uwa.edu.au
  • Run the following commands to install google chrome (chromium is already installed). Do not install using a .deb from a web browser because it then doesn't automatically update:
  • sudo add-apt-repository "deb http://dl.google.com/linux/chrome/deb/ stable main"
    wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
    sudo apt-get update
    sudo aptitude install google-chrome-stable
  • Set up the current printer - (blacklight at time of writing)

    • Open the print control panel
    • Add printer directly (list its hostname in the insert field)
    • If the definition file cannot be located, download from the manufacturer's website (some googling may be required)
    then (These ones are non-crucial/take a long time_)
  • apt-get install {lyx texlive}
  • Log in and go to login window preferences in the main menu
    • Set theme to elegance
    • Go to options and deselect "automatically select the last logged in user"
    • Also change the default session from "Automatically detected" to "cinnamon"

Install vivaldi browser (there's no repo package at the moment) - go to https://www.vivaldi.com and install from there

Linux Laptops

* These are not part of the SOE, set them up however you like, but try to follow the instructions above for Linux desktops.

Proprietary NVidia Drivers

NOTE: nouveau is preferred if it works, as it integrates with the kernel.

  1. Locate the driver edition for the card (the major number of the driver version specified on http://www.nvidia.com/Download/index.aspx?lang=en-us)

    • DON'T DOWNLOAD FROM HERE
    • Remember to select "Linux x64" as the OS
  2. Install the relevant package sudo apt-get install nvidia-<VER>

    • E.g. nvidia-340 for the GeForce 9600

  3. Reboot
  4. If the graphics don't work (e.g. falls back to software rendering), sudo apt-get purge nvidia-<VER>

Debian or Ubuntu

  • Add a root user and nuke the initial unprivileged user
  • Ensure the package sources are pointing at AARNET's mirror, not UWA's
  • Set up LDAP by following the instructions in the linux servers section of this page

  • Modify /etc/fstab to mount /away

Something like this (differs with distro):

  • services.ucc.gu.uwa.edu.au:/space/away/home     /home   nfs     nfsvers=3,auto,rw,tcp,nosuid,nodev,rsize=8169,wsize=8169,soft   0       0
  • Add the UCC root SSH keys: add the hostname to /home/wheel/bin/uccroot/push.sh, then run that script. Ensure the following packages are installed:

  • blender build-essential cvs chromium-browser compizconfig-settings-manager freeglut3-dev geeqie gimp glew-utils gnome-desktop-environment gnucash hugin inkscape jhead joe keepass2 ladvd libglew-dev libglew1.8 locate mplayer nasm nfs-common nslcd pidgin rssh openjdk-7-jdk openssh-server python remmina subversion thunderbird tig ubuntu-restricted-extras vim-gtk vlc zsh

Ensure the following packages are NOT installed:

  • ubuntuone-client unity-lens-shopping

then (These ones are non-crucial/take a long time_) apt-get install {lyx}

  • Ensure wheel group and sprocket group have sudo permission sudo visudo

  • %wheel ALL=(ALL:ALL) ALL
    %sprocket ALL=(ALL:ALL) ALL

Install vivaldi browser (there's no repo package at the moment) - go to https://www.vivaldi.com and install from there

Graphics Don't Work?

If you get messages like "Hooray! GNOME3 won't work because your graphics hardware does not support it", or glxinfo segfaults, or glxgears does not show anything, then you have entered the wonderful world of troubleshooting graphics drivers!

NVidea should just work. If you have problems, remove the nouveu driver and replace it with the non-free nvidia driver.

If things seem totally fucked, you probably have an AMD graphics card. Eg:

  •     $ lspci | grep vga
        00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI BeaverCreek [Radeon HD 6550D]    

You have two options; if one doesn't work try the other.

  • Install the debian non-free version of fglrx which may or may not explode

  • Install the official AMD fglrx which will definitely explode but may take longer to do so: http://support.amd.com/en-us/download

If none of this works you are doomed and need to try a different OS. However, debian or ubuntu are usually actually the best for fglrx, so you're probably still doomed.

OpenSUSE

  • Rule 1: don't go messing with text config files (eg ldap, pam, nsswitch) - OpenSUSE is mostly configured through the GUI, and you'll be frustrated if you try and mix the two.
  • You can put it on ldap within the installer, so you won't need to create an unprivileged account like in Ubuntu
  • Put the machine on LDAP
    • Open YaST, either from the GUI or the command line, and select 'LDAP Client'
      • Set the address of LDAP servers to mussel.ucc.gu.uwa.edu.au motsugo.ucc.gu.uwa.edu.au

      • Click on 'Fetch DN' and the UCC dn should appear
      • 'Use LDAP' should be selected, deselect all other checkboxes
      • Click on advanced configuration
        • Deselect 'Use SSSD'
        • Set the user map to ou=People,dc=ucc,dc=gu,dc=uwa,dc=edu,dc=au
        • Set the password map to dc=ucc,dc=gu,dc=uwa,dc=edu,dc=au
        • Set the group map to ou=group,dc=ucc,dc=gu,dc=uwa,dc=edu,dc=au
    • Run the following commands from a terminal as root:
      • pam-config -a --ldap

      • pam-config -d --sss

      • Running id accmurph should show uid=666(accmurph) gid=666(winadmin) groups=666(winadmin) if everything is working

  • Mount user home directories
    • Ensure there is a /away export to the machine from mylah
    • Delete or move the old /home directory: rm -rf /home (don't even leave an empty directory in / )

    • Set up automounting of home directories
      • OpenSUSE 11.4:
        • Uncomment the "/net -hosts" line in /etc/auto.master
        • Ensure you can ping mylah
        • Open YaST, go to 'System Services (Runlevel)', and enable the autofs and rpcbind services FROM SIMPLE MODE
        • Create a magic link to the home directories ln -s /net/mylah/space/away/home /home

        • Check this works by going to /home and listing the directory contents
        • If things aren't working the way they should, test mounting /away manually with the mount command after creating the /home directory. Don't forget to unmount /home and delete the empty directory when you're done.

      • OpenSUSE 12.2:
        • autofs is deprecated! Yay! We use systemd now.
        • From YaST, go to 'System Services (Runlevel)', and enable the 'nfs' and 'rpcbind' services.
        • Edit /etc/fstab (even though, strictly speaking, it's deprecated -- gotta love systemd)
        • Add this line:

          services.ucc.gu.uwa.edu.au:/space/away/home     /home   nfs     nfsvers=3,rw,tcp,nosuid,nodev,rsize=8169,wsize=8169,soft,nolock,noauto,comment=systemd.automount   0       0 
        • Maybe reboot (it can't hurt, right...)
        • ls /home (or do something in the directory in order to make it mount)
        • Everything should work
      • Check this is still working after a reboot!
  • Run a quick upgrade of all packages using zypper up before going any further.

  • The package management tool in OpenSUSE is zypper. Install the following packages using zypper install from a terminal

  • blender compiz compiz-plugins-extra compizconfig-settings-manager findutils-locate finger freeglut-devel glew glew-devel gcc geeqie gimp git hugin jhead joe nasm opera pidgin MozillaThunderbird zsh
  • OpenSUSE also supports 'pattern' packages (much like the build-essential package in Debian). Install the following patterns using zypper install -t pattern

  • devel_C_C++ devel_ide devel_java devel_mono devel_perl devel_python devel_qt4 devel_rpm_build devel_ruby devel_web remote_desktop 
  • OpenSUSE 11.4 only: Compiz on OpenSUSE 11.4 has a problem where compiz-manager doesn't start correctly for users using compiz, so those users have no window borders, this can be solved by creating /etc/xdg/autostart/compiz-manager.desktop and putting the following contents in it:
  • [Desktop Entry]
    Type=Application
    Exec=/usr/bin/compiz-manager
    Hidden=false
    X-GNOME-Autostart-enabled=true
    Name[C]=Compiz Manager (fix)
    Name=Compiz Manager (fix)
    Comment[C]=Fixes the annoying issue
    Comment=Fixes the annoying issue
  • Install suitable graphics drivers. For ATI and nVidia chips see: http://en.opensuse.org/SDB:ATI_drivers and http://en.opensuse.org/SDB:NVIDIA_drivers

    • To use nouveau instead of nvidia, remove nvidia-computeG02 nvidia-gfxG02-kmp-desktop x11-video-nvidiaG02 and install Mesa-nouveau3d
    • Check compiz is working after a reboot (wobbly windows!)
  • Install vlc from this site: http://www.videolan.org/vlc/download-suse.html

  • Install google chrome (these instructions assume 64-bit openSUSE)
    • wget https://dl-ssl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

    • zypper install google-chrome-stable_current_x86_64.rpm

  • Enable ssh and add the root keys:
    • Enable the sshd service through YaST
    • Allow Secure Shell Server through the firewall using YaST
    • Add the hostname to /home/wheel/bin/uccroot/push.sh and run that script
  • Add wheel to sudoers using visudo, and delete the two lines in the file that are mentioned in the comments in the file
  • Add printers. Phosphorous on mussel is currently best added as a samba printer

Mac Desktops

  • Do a fresh install of the operating system
  • Enable Remote Login http://support.apple.com/kb/PH18726

  • Add the UCC CA
  • Settings > Users and Groups > Join Network Account Server

    • Open Directory Utility
      • Select LDAP then click the pencil icon
      • Add mussel.ucc.gu.uwa.edu.au
      • Enable Encrypt using SSL
    • Set RFC2307 mappings
    • Set search base to dc=ucc,dc=gu,dc=uwa,dc=edu,dc=au

    • Edit the server settings
      • Disable "Use custom port"
  • Set up home directories
    • Open terminal and sudo to root
    • mv /home /home2 to move the old /home out of the way, probably something still has it open

    • ln -s /net/services.ucc.gu.uwa.edu.au/space/away/home /home to use the automounter for /home, if you don't understand this, ask.

    • ls -l /home should now show ucc, wheel, etc. If not you need to work out why.

  • Reboot and SSH etc. should work.
