    • apt-get, wget, browsers... → through privoxy (env. set in /etc/bash.bashrc, /etc/profile, /etc/environment)
    • ftp → direct connection (no solution...)
  • Proxy configuration - network home:
    • sshproxy → direct connection; forward IMAP/SMTP ports; opens a SOCKS5 proxy (useless).

    • Set scrollback to 5120 lines

    VirtualBox

    • Installed with apt, version 3.2.0
    • VirtualBox is launched as user root (because it seems that only the current user and root can access PulseAudio in a same X session — see [3])
    • Create vmdk to boot windows partition /dev/sda2. Update the MBR code to remove GRUB. Repeat this every time the partitions change:
    sudo dd if=/dev/sda of=opensource.mbr bs=512 count=1
sudo apt-get install mbr                                 # For command "install-mbr"
sudo install-mbr -i n -p D -t 0 opensource.mbr
sudo VBoxManage internalcommands createrawvmdk -filename nxl67002-sda2-mbr.vmdk -rawdisk /dev/sda -partitions 2 -relative -mbr opensource.mbr
    • Allow user beq06659 to launch VirtualBox through user root. Add to /etc/sudoers:
    beq06659	ALL=NOPASSWD: /usr/bin/VirtualBox
    • Helper function to add to e.g. ~/.bashrc :
    function winbox() {
    sudo /usr/bin/VirtualBox&
}
    • Host-only network vboxnet0
      • IPv4 address/mask 192.168.11.150/255.255.255.0 (same as AndLinux)
      • DHCP Server address/mask 192.168.11.1/255.255.255.0, Lower/Upper address bound 192.168.11.2/192.168.11.99

      • Base Memory 1536 MB, 2 cpus, VT-x/AMD-V enabled, Nested Paging enabled

      • Network PCnet-FAST III, Host-only adapter, vboxnet0
      • Machine folder: permanent, full access, /windows/d as d
      • Default layount: seamless mode, extended desktop (windows taskbar on external monitor, gnome taskbar on primary monitor, workspace switcher panel on top bar)

    To Do

    • Issue - ssh disconnects after some time, autossh can't reconnect. Even doing a simple ssh does not work anymore. Might be due to broken ssh-agent
      • Disable auto-run of Gnome ssh-agent, enabled back my ss-agent script
    • Issue - synergy unstable. Sometimes CTRL key does not work anymore in the client...
      • Look for alternatives: Synergy+ (SynergyPlus), or x2x (see Synergy page on wikipedia).
    • Issue - VirtualBox - UE slower gui refresh since update to VirtualBox 3.2.4 (previous version was 3.2.0)
