cwrap 1.0.0 – testing your full software stack …

flattr this!

on one single machine!

FOSDEM/Brussels, February 2nd, I gave a talk about cwrap. I announced and released version 1.0.0 of cwrap, a set of tools to create a fully isolated network environment to test client/server components on a single host.
It provides synthetic account information, hostname resolution and privilege separation support. The heart of cwrap consists of three libraries you can preload to any executable.
The libc wrapper project does not require virtualization and can be used to build environments on different operating systems. The project
consists of a socket wrapper, NSS module wrapper (users, groups, hosts), and a (s)uid wrapper with support for GNU/Linux, BSD and Solaris.

The origin of these wrappers is the Samba project, where the wrappers are in use since many years to successfully test their protocol implementations. Now it is possible to use them outside of the Samba project. The wrappers have been improved and are loaded with new features.
