Scripts

There are a number of useful scripts included with the distribution. Some of these scripts are only useful during build and development, but other scripts are intended for end users to be able to use. These scripts may be installed with n2n as part of your operating system package.

Short descriptions of these scripts are below.

scripts/hack_fakeautoconf.sh

This shell script is used during development to help build on Windows systems. An example of how to use it is shown in the Building document

scripts/indent.sh

This shell script is a wrapper for the uncrustify C code style checker which checks or applies a set of rules to the code. It is used during the automated lint checks.

scripts/test_harness.sh

This shell script is used to run automated tests during development.

scripts/n2n-ctl

This python script provides an easy command line interface to the running n2n processes. It uses UDP communications to talk to the Management API. By specifying the right UDP port, it can talk to both the edge and the supernode daemons.

Example:

• scripts/n2n-ctl --help
• scripts/n2n-ctl help

scripts/n2n-httpd

This python script is a simple http gateway to the running edge. It provides a proxy for REST-like HTTP requests to talk to the Management API.

By default it runs on port 8080.

It also provides a simple HTML page showing some edge information, which when run with default settings can be seen at http://localhost:8080/ (Also a http://localhost:8080/supernode.html page for the supernode)

Example:

• scripts/n2n-httpd --help
• scripts/n2n-httpd 8087

scripts/n2n-gateway.sh

A sample script to route all the host traffic towards a remote gateway, which is reachable via the n2n virtual interface.
