phut's Introduction

Welcome to Trema

Trema is an OpenFlow controller programming framework that provides everything needed to create OpenFlow controllers in Ruby. It provides a high-level OpenFlow library and also a network emulator that can create OpenFlow-based networks for testing on your PC. This self-contained environment helps streamlines the entire process of development and testing.

Prerequisites

Ruby 2.0.0 or higher (RVM).
Open vSwitch (apt-get install openvswitch-switch).

Documentation

See https://relishapp.com/trema/trema/docs for links to documentation for all APIs.

Sample Code

Study sample code for implementation examples of Trema features. Each sample code project is executable source example of how to write a OpenFlow controller using Trema Ruby API.

sh "sudo /sbin/sysctl -w net.ipv6.conf.#{bridge_name}.disable_ipv6=1 -q"

This is because Raspbian disalbes IPv6 by default, so you should enable IPv6 before disabling it.
For example, you should do:

$ sudo modprobe ipv6
$ echo ipv6 | sudo tee -a /etc/modules

My environment:

Making vswitch and vlink fails in CentOS6 due to sysctl

When I use phut 0.6.6 in CentOS 6.7(32bit), making vswitch and vlink fails. The commands

sudo /sbin/sysctl -w net.ipv6.conf.#{bridge_name}.disable_ipv6=1 -q      # open_vswitch.rb
sudo /sbin/sysctl -w net.ipv6.conf.#{@device_a}.disable_ipv6=1 -q      # virtual_link.rb

result in

error: "-q" must be of the form name=value

and it seems that "-q" is recognized as an argument of "-w". So the command

sudo /sbin/sysctl -q -w net.ipv6.conf.#{bridge_name}.disable_ipv6=1

works in CentOS 6.7 successfully.

My sysctl version is below.

$ sysctl --version
sysctl (procps version 3.2.8)
