Added ethernet.rb  and made rspec work.

To run the rspec, eg:

sudo rspec socket_wrapper_spec.rb

CANNOT be using Wireless connection for the rspec to work. MUST be using Ethernet.

Boring details of how I got here

RawSocket mac should have 6 bytes
Failure/Error: let(:mac) { EtherShell::RawSocket.mac eth_device }

SOCKET(2)                        Linux Programmer's Manual                       SOCKET(2)

NAME
       socket - create an endpoint for communication

SYNOPSIS
       #include           /* See NOTES */
       #include 

       int socket(int domain, int type, int protocol);

DESCRIPTION
       socket() creates an endpoint for communication and returns a descriptor.

       The  domain  argument  specifies  a communication domain; this selects the protocol
       family which will be  used  for  communication.   These  families  are  defined  in
       <sys/socket.h>.  The currently understood formats include:

       Name                Purpose                          Man page
       AF_UNIX, AF_LOCAL   Local communication              unix(7)
       AF_INET             IPv4 Internet protocols          ip(7)
       AF_INET6            IPv6 Internet protocols          ipv6(7)
       AF_IPX              IPX - Novell protocols
       AF_NETLINK          Kernel user interface device     netlink(7)
       AF_X25              ITU-T X.25 / ISO-8208 protocol   x25(7)
       AF_AX25             Amateur radio AX.25 protocol
       AF_ATMPVC           Access to raw ATM PVCs
       AF_APPLETALK        Appletalk                        ddp(7)
       AF_PACKET           Low level packet interface       packet(7)

Didn't fix


After talking to Victor, he told me that I don't have ethernet.rb, the equivalent of ether_shell.rb. So modified ether_shell.rb into ethernet.rb.

Fixed.

Read about Ruby Modules

RSpec
Read about Rspec Testing. Link 1. Link 2 gives a great introduction to RSpec, and good TDD example. let(). :colon_things

See how it's applied to Victor's ether_shell: git clone https://github.com/pwnall/ether_shell.git and navigate to its "spec" directory to run the rspec tests.

Install rspec: sudo gem install rspec.

Run an RSpec test to see it produces RSpec outputs! :)
ether_shell/spec/ether_shell$ rspec raw_socket_spec.rb
