Show contents of windows\assembly folder or similar

In case you just want to view the original content of the windows assembly folder, or other system folders, you can do the following:

1. In console, type cd /d %windows%\assembly
2. Type: attrib -r -h -s desktop.ini
3. Type: ren desktop.ini desktop.bak

Reload the explorer window to see the actual contents...

If you want to restore the original view, just rename the desktop.bak back to ini.

This works also for other system folders, e.g. fonts folder.

In case you want two seperate views at the same time, you can do:

Check and fix shellshock vulnerability in bash/debian

Bash shell has a serious vulnerability that can be exploited by
an remote attacker in some cases.

To check if you are using bash can be done with entering the following at the shell:
echo $0
echo $SHELL

If it prints bash, then you are using bash.

Debian Wheezy is using dash by default since version 6.10, so it should not be vulnerable.

If your version of bash is vulnerable can be tested by entering the following in bash:
env X='() { (a)=>\' bash -c "echo echo vuln"; [[ "$(cat echo)" == "vuln" ]] && echo "still vulnerable :("

Fix heartbleed bug on Debian

I tried fixing the heartbleed bug on my debian installation.

Most of the websites suggest, that updating to the newest Openssl release
fixes the problem.

Howevery, an "apt-get install openssl" did not fix the problem.
The test website said - still vulnerable, although
the newest openssl release was fetched by the apt command.

I found a more thoroughly explanation of a possible fix at:

Drush install error on Debian

Getting the newest drush (Drupal shell) version via PEAR can give the following error:

Discovering channel over http:// failed with message: channel-add: Cannot open "" (Cannot download non-http URL "/channel.xml")

Using the following command sequence can solve the problem:

pear upgrade –force Console_Getopt
pear upgrade –force pear
pear upgrade-all
pear channel-discover
pear channel-discover
pear install drush/drush

You have to run the channel discovery twice to add the channel. The first try

Compiling error with APC for php5 - debian

Installing APC php5 cache from pear is a pretty easy task:

apt-get install php-pear
apt-get install php5-dev build-essential
pecl install apc

However, if the last step fails with the following errors,

'apc_regex' has no member named 'preg'
'apc_regex' has no member named 'nreg'

you are missing the perl regular expression libraries on your system!

Installing can be done with

apt-get install libpcre3-dev

as root user.

pecl install apc
once again will then hopefully work.

Intel Indeo Video Codec missing on Windows 7 (64 bit)

I have tried to open a self recorded video with VirtualDub,
a Freeware Video Editing Software.

However, the video file was recorded by a camcorder using Intel Indeo
Video format, and VirtualDub was not able to open it.

I don't know whether the codec is supplied with Windows 7 or not, but
after installing the K-Lite Codec pack Standard from, it
still could not open the file properly.

It seems that the codec has to be registered in Windows seperately:
Start a command prompt as Administrator and change to the directory

Connect a ubuntu linux vm to an microsoft NTLMv2 proxy

In order to connect a ubuntu linux vm to a microsoft proxy server, several steps are involved to produce a working connection.

Several ubuntu versions (maybe a new version can do this automatically) are not able to connect to such a proxy without further tweaking.

The software which is needed to perform the NTLM authentication is named Cntlm.
It can be found here:

Download the latest version, untar and compile it using the default settings:
./configure --prefix=/url/local

Change linux keyboard layout persistently

In order to change the keyboard layout of a linux machine persistently, making it survive also a reboot, the file /etc/conf.d/keymaps has to be changed.

There you can find the options KEYMAP, which has to be changed to one of the keymaps found in /usr/share/keymaps and subfolders.

For example if the keyboard has to be set to a default german layout, you can use:

Once you restart the machine, the layout will be applied.

Samba compilation problem

Since a serious bug has been found in samba recently, i had to compile samba server
on my linkstation.

I downloaded the latest version, the first issue was which source folder i had to use, either source3 or source4, it turned out to be source3 (source4 seems to be a new, experimental version).

Since i wanted to install to the local folders, i proceeded like for rtorrent with:
./configure --prefix=/usr/local
make && make install

The second problem i encountered after the build, after i ran smbd -V to check the version, the libraries
