agedu: Unix / Linux Command For Tracking Down Wasted Disk Space

Posted on by

Say hello to agedu tool (pronounced as ‘age dee you’) – it scans a directory tree and produces reports about how much disk space is used in each directory and subdirectory, and also how that usage of disk space corresponds to files with last-access times a long time ago. In other words, this command might help you to free up disk space.

Microsoft Kills Expression Suite

Posted on by

Visual Studio is Microsoft’s only flagship development system and this raised the question of why Expression Blend, the XAML user interface designer, was a standalone product. Not all Visual Studio programmers were even aware of what Expression Blend could do for them. For example, books on programming Silverlight or Windows 8 would often concentrate on using Visual Studio and mention Expression Blend as an afterthought.

SHODAN – Computer Search Engine

Posted on by

So what does SHODAN index then? Good question. The bulk of the data is taken from ‘banners’, which are meta-data the server sends back to the client. This can be information about the server software, what options the service supports, a welcome message or anything else that the client would like to know before interacting with the server.

What ports does SHODAN index?

The majority of data is collected on web servers at the moment (port 80), but there is also some data from FTP (23), SSH (22) and Telnet (21) services. There are plans underway to expand the index for other services. Let me know if there are specific ports you would like to see included.

Wifi sniffing digital picture frame

After gutting the laptop and putting it in a custom picture frame, Driftnet, a program that listens network traffic and picks out images from TCP streams, was installed. [AUTUIN] tested his build with an open wireless connection in his building. The results provided a wonderful narrative that started with pictures from news sites than slowly devolved to pictures from a hot-or-not style website, an online dating site and finally pictures from the inevitable conclusion of that browsing session.

Trace the Process and See What It is Doing with strace

Posted on by

strace is a useful diagnostic, instructional, and debugging tool. It can save lots of headache. System administrators, diagnosticians and trouble-shooters will find it invaluable for solving problems with programs for which the source is not readily available since they do not need to be recompiled in order to trace them. This is also useful to submit bug reports to open source developers.

via Debugging Tip: Trace the Process and See What It is Doing with strace.

Run strace against /bin/foo and capture its output to a text file in output.txt:
$ strace -o output.txt /bin/foo
