In this presentation, we would like to introduce a tool we have been working on for the last couple of months. Our main goal is to make networking tests and reproducers as automated and portable as possible.
Testing network stacks requires a fair amount of configuration to be done on multiple machines. The configuration itself is a part of the test. However, it is often highly dependant on the environment and unfortunately, when the environment changes (due to move to a different hardware/site, changes in the addressing, or simply updates of the operating system) the configuration often breaks.
With LNST, we try to overcome these problems of transferring network configuration between different environments. We will demonstrate the ideas and the concepts we are working with, as well as the features that are a part of Linux Network Stack Test.
