How to protect your equipment against EMP?

Electromagnetic pulse (EMP) occurs with a nuclear explosion in the atmosphere.

Simply said it destroys electronics. After an EMP there will be no working radio, television, telephone, power-grid, car or cash-machine.
Banks will stop working and even a millionaire will not be able to buy any food.
People who need medicine or care will have to try without.

Although vacuum tubes are far more resistant to EMP than solid state devices, other components in vacuum tube circuitry can be damaged by EMP.



Protecting against an EMP can be done with the help of a cage of Faraday.
Put your vacuum tube transceiver in a metal box. Make sure the equipment does not touch the metal cage/box. Don't ground the cage/box.

To operate your now state of the art station after nuclear disaster strikes you need power. Remember the power-grid is pre nuclear history and you need your own generator and battery to get up on the air.

Howto Hack MS Windows with Linux

Q - What if you cannot access your MS Windows operating system due to a lost administrator password?

A - Start using a free simple OS like Ubuntu or Gentoo.
Or hack MS Windows so that it does not need a password any more.

Boot into Linux using USB or CD. If you dont have an USB or CD with a linux distribution on it use unetbootin to create one. This post was tested using Ubuntu 9.10.

Enter the terminal.
sudo apt-get install chntpw
Mount the NTFS drive allowing read/write.
navigate to WINDOWS/system32/config
chntpw SAM
If the password is left blank (*) you can boot into administrator without using any password ever.

(K)ubuntu 8.04 on the HP Mini 2133 (FU338EA)

Finally the screen problems are solved.

Here is how I finally got the HP Mini 2133 (FU338EA) working correctly with kubuntu.

First install kubuntu-8.04.2-desktop-i386.iso

Then install the VIA video driver.
Browse to http://linux.via.com.tw/support/downloadFiles.action
select "Ubuntu 8.04 LTS" and download the stable version.
Extract the files.
Open a terminal and go inside the directory you just created and run ./vinstall
Now download a new xorg.conf file from: https://wiki.ubuntu.com/LaptopTestingTeam/HP2133?action=AttachFile&do=get&target=xorg.conf
Rename your existing xorg.conf file to xorg.conf.old and replace the original one with the one you just downloaded.
To restart the X server press 'CTRL + ALT + Backspace'
If all is well relax and enjoy. Otherwise:

Edit xorg.conf.
change the PanelID value in "Device" section of xorg.conf. Correct PanelID value for 1024x600 is 17 (Add line 'option "PanelID" "17"')

How to update the BIOS of an Asus EEE pc 1000

Start up with the USB stick attached and hold both ALT and F2 keys pressed and the BIOS update will run. The screen will show the update process.

I updated from 803 to 913 successfully and without any problems.

Siemens gigaset WLAN camera Security problem

The Siemens gigaset WLAN camera has a big security problem.
Telnet and FTP, port 23 and 21, are completely open to this camera. Anyone can connect to yourcameraIP:23 with a telnet client as root and access the linux router running in the camera without even the need for a single password.
On connecting the camera returns:

Linux 2.4.19-uc1 (SI4e7141) (ttyp0)

BusyBox v0.60.3 (2005.08.22-11:11+0000) Built-in shell (msh)
Enter 'help' for a list of built-in commands.

help does not work.
# help
help: not found
#

Possible commands are:

cat
cd
date
df
du
echo
exit
free
hostname
ifconfig
kill
killall
ls
lsmod
mount
nslookup
ping
ps
pwd
reboot
route
set
uptime
whoami



The password of the wireless network is then clearly revealed in a 'file' and open to any visitor who has the capability to use a Linux terminal. Read the 'password file' with the cat command.
No password needed. Ever.

It seems Siemens has no clue about network security. Siemens has no firmware upgrade even though adding a secret password to user root is essential for this to be a usable and save product. Be warned, don't use this camera without adding a firewall.

Siemens gigaset WLAN camera

The Siemens gigaset WLAN camera and its hidden features.
This is not in the manual.

This IP WLAN camera comes with Windows software and can be viewed with internet explorer together with active X.

If you need to the stream can be picked up by any application that can handle .ASF streams.
The stream is found at:
http://-your url-/img/video.asf
With this URL you can watch the camera with many mediaplayers that can open the .ASF format like WinAmp and Windows Media Player even if you are not using Windows.

To make the stream available over the internet and inside the LAN via a router, use an extra port besides port 80. For instance use extra port 1080.
In the router add a port foreward from 1080 to -IP-camera-:1080.


Inside the LAN look at port 80, outside the LAN via the internet, look at port 1080.
