For DOS programs, date and time stamps were used to mark versions of files. For instance, Turbo Pascal 6.0, had a 06:00 time stamp on every file.
You can still do this in Windows, but need to watch for a couple of things:
- daylight saving time
- more than one time stamp per file
There are various ways to do it. Besides a graphical Attribute Changer at www.petges.lu (thanks User Randolf Richardson), these are console approaches via How can I change the timestamp on a file?:

Last week, I thanked Jaykul for helping me out on PowerShell.
But he taught me another thing that was new for me: on his site, he has hidden his email address behind a 302-redirect.
I didn’t even realize that was possible until I saw his site start my mail program without initially showing a mailto in the url. A quick check showed me he was using a 302-redirect: Read the rest of this entry »

I always forget where SuSE keeps its’ version number.
Hence my alias:
alias suse_version='cat /etc/SuSE-release'

Fazit:
You’ll probably want a standard OS for day to day tasks, and only use Tails if you really need to remain anonymous.

Fun project with potential: pickhardt/betty that was pointed to me by Ilya Grigorik – Google+.
Betty is a natural language (for now: English based) front end for tools like curl, find, wc, whoami, find, etc.
It requires ruby, and runs on *nix or Mac OS X (where it uses osascript for iTunes).

SDB:System upgrade – openSUSE.
Every once in a while, I feel like I have been living under a stupid rock.
This was one of these cases. About 5 years ago, openSUSE added this feature:
openFATE – #305634: Debian-like dist-upgrade live system full version upgrade.
It is awesome, requires a bit of twiddling and afterwards you have a system that:
- was updated in-place while live
- is the most current openSUSE version
I don’t know of any drawbacks yet (will soon try it). If I find ones, I will post a new entry here.
The basic steps are like these: Read the rest of this entry »

I needed AntiVir on an openSUSE workstation.
Too bad the default installation package from YaST installed an old license: AntiVir would not work, and I was getting emails like these at regular intervals:
<br />Date: Thu, 25 Apr 2014 08:57:11 +0200<br />From: Cron Daemon <root@....><br />To: root@....<br />Subject: Cron <root@...> /usr/lib/AntiVir/guard/avupdate-guard --product=Scanner > /dev/null<br /><br />Error: No valid license was found<br />
After searching the web for a while, I found a lot of posts with wrong information, basically coming down to these 2:
At the bottom of the post, you will find a small shell script that I use to keep the hbedv.key up-to-date.
First some more about HBEDV, then how I found about the new download location, and a command to show you the current license information. Read the rest of this entry »

I’ve been using rsync as my MacGyver style backup-tool of choice on *nix systems and sometimes even Windows systems.
It works both locally and remotely, is simple to setup and over the years has gathered a lot of nifty functionality.
It is way easier to backup using rsync one directory to another than using tar (tar has the benefit of putting everything in one archive though) using a command like this:
rsync -aiv /path/to/source/directory /path/to/destination/directory
For remote copies, I usually add replace -aiv with -aivz or with -aiz.
Given the ubiquitous of hard disk space, I hardly compress or archive directory trees for archival purposes any more.
For an introduction of basic functionality read Everything Linux – A Tutorial on Using Rsync. An article from 1999 that is still very valid now.
Besides my praise for rsync, there are a few small things I want to mention in this article:
- Sometimes more is less. Recently someone asked me how to force rsync not to keep the time stamps of files.
He wasn’t the first to ask.
The solution is simple: since the -a option archive option implies -t, so the solution is to expand -a into its parts -rlptgoD, then remove the -t from that.
- The –link-dest=DIR option was added in about 2004 (later: no, link-dest was added to rsync 2.5.6 in januari 2003), which allows you to do incremental backups. Read the rest of this entry »

Reaver-WPS is an excellent tool to test the security of your WPA/WPA2 secured network against the WPS vulnerability.
Getting Reaver 1.4 (which contains wash to scan WiFi networks) to compile out of the box on OS X Mavericks (which is 10.9; why can’t they keep a successive version number in the product name?) didn’t work.
So I downloaded the adapted source pack from one of the comments in Issue 245 – reaver-wps – Support for Mac OS X? – Brute force attack against Wifi Protected Setup – Google Project Hosting (as the diff still not has been applied to the codebase)..
wash will detect most, but not all networks. I’ve net yet tried WireShark, wpscan and wspy yet (they re supposed to get all of them).
To speed up the checking process I tried on install aircrack-ng to associate a Mac with the target network. Compiling aircrack-ng on a Mac from source didn’t work at all. But after installing MacPorts, I could get the MacPorts version of aircrack-ng to work. The bad news: I could not get aircrack-ng to associate to the network.
So these were the commands I used: Read the rest of this entry »
