Overview

The goal of this Go project is to consolidate all low-level network testing "daemons" into one place. In network testing we frequently have need of simple daemons (common/Runner) that perform some "trivial" set of actions on a socket.

Usage

• A package for each general area that is being tested, for example nat/ will contain Runners that test various NAT features.
• Every runner should be registered via main.go:makeRunnerMap().
• Runners receive a JSON options structure as to their configuration. Run() should return the disposition of the test.

Runners can be executed into two different ways, either through the the command-line or via an HTTP request:

Command-line

$ ./net -runner <runner> -options <json>
./net \
  -runner nat-closewait-client \
  -options '{"RemoteAddr":"127.0.0.1:9999"}'

HTTP server

$ ./net --serve :8889
$ curl -v -X POST localhost:8889/run/nat-closewait-server \
  -d '{"LocalAddr":"127.0.0.1:9999"}'
