This is a basic setup to boot Arch Linux over PXE.

1. Mount the Arch Linux image.

    mkdir -p /mnt/archiso
    mount -o loop,ro archlinux-2013.02.01-dual.iso /mnt/archiso
   

2. Connect your server with your client and setup the server interface for that connection with a static ip address in the /etc/network/interfaces file.

    auto eth0
    iface eth0 inet static
    address 192.168.1.100
    netmask 255.255.255.0
    gateway 192.168.1.1
   

   Restart the network interface.

    ifdown eth0
    ifup eth0
   

3. Configure dnsmasq as dhcp- and tftp-server in /etc/dnsmasq.conf.

    dhcp-boot=/mnt/archiso/arch/boot/syslinux/pxelinux.0
    dhcp-option-force=209,boot/syslinux/archiso.cfg
    dhcp-option-force=210,/mnt/archiso/arch/
    enable-tftp
    tftp-root=/mnt/archiso
   

   Restart the service.

    service dnsmasq restart
   

4. Start an http-server inside the Arch Linux mount folder.

    python -m SimpleHTTPServer 80

    umount /mnt
    

    Set legacy BIOS bootable on partition 1:

    sgdisk /dev/sda --attributes=1:set:2
    
    reboot
    

15. Configure network

    dhcpcd
    

    or for wifi

    pacman -S net-tools wireless_tools wpa_supplicant wpa_actiond dialog

This is a description of how to setup a basic working system, after installing Ubuntu Minimal.

First install X.org, Xfce to get a graphical interface and wicd to manage your network connections:

sudo aptitude install xorg xfce4 wicd

Then type startx to run the graphical environment (if this does not work, add exec startxfce4 to your .xinitrc in your home directory).

System Tools

conky for system monitoring and HardInfo for hardware informations.

sudo aptitude install xfce4-terminal conky hardinfo

Users

Create user:

sudo adduser <username>

Add user to certain groups:

sudo usermod -aG dialout,cdrom,floppy,audio,video,plugdev,fuse,lpadmin <username>

Updating/Upgrading

sudo aptitude update
sudo aptitude safe-upgrade
sudo aptitude full-upgrade

Windows Network

To browser and create windows network share you need samba (pyNeighborhood is a SMB/CIFS browsing utility):

sudo aptitude install smbfs pyneighborhood

Media Handling

Xarchiver for compressed files, VLC for Video Playback, Epdfview for PDFs, Transmission for torrents, Chrome for web-browsing and Flash/Java plugins.

sudo aptitude install xarchiver vlc epdfview transmission chromium-browser flashplugin-nonfree flashplugin-installer chromium-codecs-ffmpeg chromium-codecs-ffmpeg-extra

Image Viewer

To compile and install ViewNior:

sudo aptitude install build-essential intltool libgdk-pixbuf2.0-dev libgtk2.0-dev
tar zxvf viewnior-1.3.tar.gz
cd cd viewnior-1.3
./configure
make
sudo make install

Tools

Latex

Install texlive from the website because the distribution contained in Ubuntu is old.

Sublime Text 2

1. Download Sublime Text 2.
2. Untar the archive tar xf Sublime\ Text\ 2\ Build\ 2181\ x64.tar.bz2.
3. Move the extracted folder to /usr/lib with sudo mv Sublime\ Text\ 2 /usr/lib/.
4. Create a shortcut for the terminal sudo ln -s /usr/lib/Sublime\ Text\ 2/sublime_text /usr/bin/sublime.

5. Create a desktop file in /usr/share/applications using sudo sublime /usr/share/applications/sublime.desktop containing:

    [Desktop Entry]
    Version=1.0
    Name=Sublime Text 2
    # Only KDE 4 seems to use GenericName, so we reuse the KDE strings.
    # From Ubuntu's language-pack-kde-XX-base packages, version 9.04-20090413.
    GenericName=Text Editor
   
    Exec=sublime
    Terminal=false
    Icon=/usr/lib/Sublime Text 2/Icon/48x48/sublime_text.png
    Type=Application
    Categories=TextEditor;IDE;Development
    X-Ayatana-Desktop-Shortcuts=NewWindow
   
    [NewWindow Shortcut Group]
    Name=New Window
