nss_wrapper

Package Name:

nss_wrapper

Summary:

A wrapper for the user, group and hosts NSS API

URL:

http://cwrap.org/

Description:

There are projects which provide daemons needing to be able to create, modify and delete Unix users. Or just switch user ids to interact with the system e.g. a user space file server. To be able to test that you need the privilege to modify the passwd and groups file. With nss_wrapper it is possible to define your own passwd and groups file which will be used by software to act correctly while under test. If you have a client and server under test they normally use functions to resolve network names to addresses (dns) or vice versa. The nss_wrappers allow you to create a hosts file to setup name resolution for the addresses you use with socket_wrapper. To use it set the following environment variables: LD_PRELOAD=libuid_wrapper.so NSS_WRAPPER_PASSWD=/path/to/passwd NSS_WRAPPER_GROUP=/path/to/group NSS_WRAPPER_HOSTS=/path/to/host This package doesn't have a devel package cause this project is for development/testing.
