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 [2]) 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)

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

mysql> GRANT ALL PRIVILEGES ON mikiwiki.* TO miki@localhost IDENTIFIED BY '********';
mysql> CREATE DATABASE mikido;
mysql> GRANT ALL PRIVILEGES ON mikido.* TO miki@localhost IDENTIFIED BY '********';
mysql> quit

Nautilus

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

Psi

• Gnome: Added Psi as startup program (Psi, /usr/bin/psi, Communicate over the jabber network).
• Options → Events → Enable popup notifications (all notifications)
• Modify Account... → Changed resource to work-ux
• Modify Account... → Automatically reconnect if disconnected
• Modify Account... → Proxy → localhost:8118

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
• 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
• 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
  • 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
