The git versioning system has two really nice features you might already heard about. One of them is git-worktree and the other are bare git repositories. This makes my life a lot easier working on Samba as often I have several feature branches I’m working on. Some features often take several months to finish. I don’t want to compile them again and again every time...

A new version of socket_wrapper has just been released. In short, socket_wrapper is a library passing all socket communications through unix sockets. It aims to help client/server software development teams willing to gain full functional test coverage. It makes possible to run several instances of the full software stack on the same machine and perform locally functional testing of complex network configurations. New in version...
TL;DR SMB3 file transfer with encryption will be 4-6 times faster with Samba 4.12 Samba is getting out of the crypto business GnuTLS >= 3.4.7 required FIPS compliance ahead Introduction More or less since the beginning of Samba, it implemented the cryptography it needed to talk to Windows on its own. One reason is that Windows didn’t follow the standards or used ciphers nobody else...

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...

Jakub Hrozek and I are proud to announce the first release of pam_wrapper. This tool allows you to either simplify testing PAM modules or your application using PAM to authenticate users. 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...
