tha Hyp0tez Blog!

Welcome to The "Rehnskrällets Blog".


I hope you will at least find this blog to contain alot o crap :)
Thing is, I have no pretention to become a pro-blogger, I just do it for fun and to learn, but also to share some knowledge.

It's a karma thingy.

You give some and get some back. Most of the posts and pages will be about/around security in the so called CyberSpace.

Feel free to nagg/compliment about things by making a comment ;)

All info/articles/posts are served As Is. It is all informational, not instructional. All guides/tips are aimed to be done in YOUR test environment, not towards anything "live"

Knowledge blasé!

Which where an old saying from my old days as a IRC nerd, pointing it towards all those who saw themselves as the utter 1337 haxx0rs, whith meerely a knowledge about how to run scripts and tools.

Gammalt (SV)

And Yet another old page ;)   Shell script Shell script i Linux/Unix är i stort sett det samma som BAT fils programmering i DOS/Windows. Enda skillnaden är hur filen är uppbyggd. alla shell-script börjar med raden –> !#/Sökvägen_till_shell_programmet_som_skall_köra_filen. Innehållet i en shell-scriptfil exekveras radvis uppifrån och ner (i stort iaf). Beroende på vilket shell [...]
