I’ve written an article about “Profiling a camera with darktable-chart” which has been published at pixls.us. The article is about how to get the same color profile of you camera for your raw developing process. If you wonder what darktable is, it is a raw developer software for photographers.
I have an AMD grahpics card and use the great Open Source driver which comes with my Linux distribution. However for image processing I want the OpenCL support of my graphics card. Currently that’s only provided by the amdgpu-pro driver. However it is possible to just extract the files needed for OpenCL and use them. Here is how to do this: Go to https://support.amd.com/en-us/download Select...
Enterprise distributions like Red Hat or SUSE are required to ship with MIT Kerberos. The reason is that several institutions or governments have a hard requirement for a special Kerberos implementation. It is the reason why the distributions by these vendors (Fedora, RHEL, openSUSE, SLES) only package Samba FS and not the AD component. To get Samba AD into RHEL some day it was clear,...

TL;DR: Parse and print .cat files: dumpmscat Introduction Günther Deschner and myself are looking into the new Microsoft Printing Protocol [MS-PAR]. Printing always means you have to deal with drivers. Microsoft package-aware v3 print drivers and v4 print drivers contain Microsoft Catalog files. A Catalog file (.cat) is a digitally-signed file. To be more precise it is a PKCS7 certificate with embedded data. Before I...

PAM (Pluggable Authentication Modules) is a layer of abstraction on top of Unix authentication. For testing PAM-aware applications we have written a simple PAM module called pam_matrix. If you plan to test a PAM...

Since I joined the libssh project we started to write tests to find regression and make development easier. This has been achieved using the a unit testing framework called cmocka which I maintain and develop. The problem is that to run these tests you need to modify the sshd configuration and setup a test user so that the tests can be successfully executed. This is...
In Samba I had a failing test suite. I have nss_wrapper compiled with debug messages turned on, so it showed me the following line: NWRAP_ERROR(23052) – nwrap_he_parse_line: 3 Invalid line[TDB]: ‘DB’ The file should parse a hosts file like /etc/hosts, but the debug line showed that it tried to parse a TDB (Trivial Database) file, Samba database backend. I’ve started to investigate it and wondered...
