Howto build secure bitcoin system

Few steps to make good secure system

1. Download ubuntu-12.04 and make a bootable usb;
2. Pull out network cabel (or wifi)
3. Boot
4. After loading, switch to console Ctrl+Alt+F1:

5. Login as root with $ sudo su and mount another storage (for example microsd card or usb) with:
  • clearing script
  • fluxbox (or other light window manager you like)
  • bitcoin-qt and blockchain

6. Cut all not-needed processes with killall and rm

Here is simple clearing script doing this:


rm /usr/sbin/atd
rm /usr/sbin/cron
rm /usr/sbin/acpid
rm /usr/sbin/cupsd
rm /usr/bin/whoopsie
rm /usr/bin/ibus-daemon
rm /usr/sbin/rsyslogd
rm /usr/sbin/bluetoothd
rm /usr/sbin/console-kit-daemon
rm /sbin/upstart-socket-bridge
rm /sbin/upstart-udev-bridge
rm /sbin/udevd
rm /bin/dbus-daemon

killall ibus-daemon
killall goa-daemon
killall jockey-backend
killall ubuntuone-login
killall geoclue-master
killall mission-control
killall bamfdaemon
killall gnome-keyring-daemon
killall unity-panel-ser
killall zeitgeist-daemon
killall zeitgeist-ft
killall whoopsie
killall modem-manager
killall cupsd
killall NetworkManager
killall bluetoothd
killall polkitd
killall console-kit-daemon
killall upowerd
killall pulseaudio
killall colord
killall dbus-daemon
killall atd
killall cron
killall rtkit-daemon
killall -9 compiz
killall upstart-socket-bridge
killall upstart-udev-bridge
killall rsyslogd
killall Xorg
killall irqbalance
killall udevd
killall acpid
sleep 2
killall Xorg

echo "nameserver" > /etc/resolv.conf
ifconfig eth0
route add default gw

Now pstree must show much less:

7. Pull in network cabel
8. install fluxbox
9. Switch to second console Ctrl+Alt+F2 and run it:  
$ xinit /usr/bin/fluxbox

10. Now you can start bitcoin-qt

Final processes should be:
