On windows I get ifconfig not found exception

testara.rb:9:in `popen': No such file or directory - ifconfig
(Errno::ENOENT)
    from testara.rb :9:in `mac_address'
    from testara.rb:8:in `mac_address'
    from testara.rb:23

On linux I get

testara.rb:23: command not found: ifconfig
testara.rb:23: command not found: ifconfig
testara.rb:23: command not found: ifconfig
testara.rb:23: command not found: ifconfig
testara.rb:13:in `mac_address': ifconfig failed (RuntimeError)
    from testara.rb:23
