Automatic Updates

Simple Settings

• GRUB — Added to file /etc/grub.d/40_custom: (Not needed anymore since VirtualBox boots Windows directly, so no risk of booting host again)

  set default="Microsoft Windows XP Professional (on /dev/sda2)"
  

• CRON - cron script for automatic backup of wikis on Noekeon's (see config files).
• PROXY - script for automatic setup of network environment (proxy, ssh...) (see config files).

Network

• Edited /etc/hosts
• Proxy configuration - network nxp:
  • sshproxy → connect to NXP proxy with sshtunnel (with NTLM auth. if needed); forward IMAP/SMTP ports; opens a SOCKS5 proxy
  • privoxy → forward to ssh SOCKS5 proxy. provide http proxy server.
  • 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).
  • privoxy → direct connection. provide http proxy server.
  • apt-get, wget, browsers... → through privoxy (env. set in /etc/bash.bashrc, /etc/profile, /etc/environment)
  • ftp → direct connection

• SAMBA/NFS CLIENT - Mount mnemosyne shares as NFS autofs (see [1]) and as SMB autofs
• Enabled/created the following automounters in /etc/auto.master:

/net           /etc/auto.net
/smb/mnemosyne /etc/auto.smb.mnemosyne

• Created configuration file /etc/auto.smb.mnemosyne
• Created SMB credential files /etc/auto.smb.mnemosyne.* (see man mount.cifs)
• Created path for mount points:

sudo mkdir /net
sudo mkdir -p /smb/mnemosyne
#ls /net/mnemosyne
#sudo mkdir -p /mnt/mnemosyne
#for i in /net/mnemosyne/volume1/*; do sudo ln -s $i /mnt/mnemosyne/$(basename $i); done

Preferences

• Appearance
• Fonts: All font size set to 8, except Title → 9.
• Keyboard Layout (System-Wide)
• Layout: Belgium (default) + USA, no separate layout
• Options: Capslock affects all keys, Alt+CapsLock or Right Ctrl+Right Shift switch layout, right alt chooses 3rd level.

(because Alt+Shift,Left Ctrl+Left Shift prevents ctrl-alt-shift shortcuts to work, Right Ctrl conflicts with VirtualBox)

• Keyboard Shortcuts

Action	Shortcut	Remark
Home Folder	Win-E (Mod4-E)	Hack Super is mapped to Win keys not needed anymore it seems
Expo key	Shift-Win-E (Shift-Mod4-E)
Activate the window menu	Shift-Alt-Space	was conflicting with Gnome DO shortcut

• Window List Panel (see here)
• Window List Content → Show windows from all workspace
• Restoring Minimized Windows → Restore to native workspace

Detailed Application Settings

Courier IMAP

• Install (reference here):
  • Create directories for web-based administration
  • SSL Certificate: /etc/courier/pop3d.pem, /etc/courier/imapd.pem
  • Postfix configuration: local only
  • System mail name: nxl67002ux.wbi.nxp.com
  • Created /etc/courier/userdb, and kept entries for root, localuser and beq06659
  • Use password from /etc/courier/userdb (method authuserdb).

Gnome DO

• Autostart, Quiet mode, notification icon, Glass theme
• Launch key: <alt>+space (! disable first Gnome global shortcut for Activate the window menu)

Nautilus

• Default view: List View
• Display, date format: YYYY-MM-DD hh:mm:ss
• List View: zoom 33%

SSH

• Installed SSH-Tunnel
• Files recovered from other installation (ssh-tunnel v2.26 + patch):

/usr/local/bin
-rwxr-xr-x 1 root root ssh-agent-refresh_andlinux.sh
-rwxr-xr-x 1 root root ssh-agent-refresh.sh
-rwxr-xr-x 1 root root ssh.pl
-rwxr-xr-x 1 root root ssh-tunnel.pl

• User beq06659 - configuration file in directory ~/.ssh:
  • id_rsa || id_rsa.pub || authorized_keys || config* || proxy.conf* || clbanner.txt

Terminal

• Set default window size (system-wide) to 150x43
• Disabled menu shortcut key (F10) (conflicts with midnight commander)
• Set scrollback to 5120 lines

VirtualBox

• Installed with apt, version 3.2.0
• We are booting Windows directly from the partition /dev/sda2. For this we create a raw disk, and update the MBR code to remove GRUB (requires package mbr):

sudo dd if=/dev/sda of=opensource.mbr bs=512 count=1
sudo install-mbr -i n -p D -t 0 opensource.mbr                     # Requires package "mbr"
VBoxManage internalcommands createrawvmdk -filename nxl67002-sda2-mbr.vmdk -rawdisk /dev/sda -partitions 2 -relative -mbr opensource.mbr

See section Advanced storage configuration in Ch. 9 Advanced topics.

NOTE! The raw disk might need to be updated every time the partitioning change on the host drive. But may be this is not required since we used -relative.

• VirtualBox must be booted as root:

gksudo VirtualBox&

• Virtual machine NXL67002
  • Base Memory 1536 MB, 2 cpus, VT-x/AMD-V enabled, Nested Paging enabled
  • Video memory 48 MB, 2 monitors, 3D accel enabled, 2D accel enabled
  • Audio host driver PulseAudio, controller ICH AC97
  • Network PCnet-FAST III, bridged, eth0
  • 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)
