I'm looking for a job! đź“Ś
If you are looking for an experienced and talented Linux system administrator/engineer and/or software developer, then you are at the right place… I’m looking for a job!
I have more then 20 years of experience professionally working as Linux/UNIX system administrator and software developer. Most work was done using open source operating systems and tools.

Hacking on Android
I wrote a document about installing Alpine Linux on Android some time ago. Today I started working on a new document about setting up a full hacking environment on Android based devices. It shows you a lot more information about running Linux distributions on your mobile/portable device…
I am using a rooted SM-T585 tablet from Samsung running a LineageOS based custom ROM.
The document is not yet finished and will be updated continuously!
Quote of the day!
Containers are containers, after all. You can put radioactive waste in a container, too. But it will still continue to radiate. You might want to do that, yes, but the contents simply won't change.

/bin/checkpw
This post was originally postet at https://xw3.org/blog/2024/09/25/checkpw/, but it was the wrong place for my personal stuff. I moved it here to keep the content more up to date.
I created a small C program to authenticate against a UNIX/Pluggable authentication module (PAM) named checkpw. This program is only for verifiying a user’s password, that is registered in /etc/passwd using /etc/shadow, or whatever PAM is configured to use.
The program returns 0 on success, 1 otherwise.
With this program, it will be possible to authenticate an xw3 application user against the system’s user database.
Currently only tested on Linux, but it should work on AIX, DragonFly BSD, FreeBSD, HP-UX, macOS, NetBSD and Solaris operating systems too. I will test API compatibility for all OS’s listed soon maybe some day… ;)
Group permissions will be handled using /etc/group in a seperate program - Maybe just with a small wrapper around the “id” command (not available yet, but it should be easy to implement).
[UPDATE]:Renamed project from checkpw to chkpwd since I believe it is more native UNIX style… ;).
[UPDATE]:Renamed project from chkpwd to chkusr because I merged other code into it. The chkpwd command still exists along with some more commands in the future.

My workspace... ;)
[UPDATE]: To be honest, my real workspace actually looks like this:
My real workspace looks sexy too! Not that chaotic, but with all features enabled! Even Tux got his place...
I believe it's virtual enough... ;)
