[orbit-user] Help with Orbit Traffic Listener

[Guillaume Jourjon]

Hi,

I might have succeed to configure the application trace_oml2 to 
interpret radiotap information. Could you test it on orbit? You'll need 
to install the newest version of both libtrace3.0.6 and 
libpcap0.8-1.0.1. These package will have to be installed manually. The 
trace_oml2 application can be built with the latest version of the 
repository of OML on http://omf.mytestbed.net/
Once this is compiled you can just add these definitions at the 
beginning of your script and it will/should start the application.

defApplication('otl2', 'otl2') {|a|
  a.version(1, 1, 2)
  a.shortDescription = "Programmable traffic passive listener"


  # defProperty(name, description, mnemonic, type, isDynamic = false, 
constraints = nil)
  a.defProperty('oml-server', 'Contact details for the oml collection 
server')
  a.defProperty('oml-id', 'ID for this oml client')
  a.defProperty('oml-exp-id', 'ID for this experiment')
  a.defProperty('interface', 'File with the definition of filters to use')
  a.path = "/root/trace_oml2"

}


defPrototype("listener") { |p|
  p.name = "Listener"
  p.description = "A node which listen for packets through a given 
interface"
  # List properties of prototype
   p.defProperty('omlServer', 'Contact details for the oml collection 
server', "tcp:#{OmlApp.getServerAddr}:#{OmlApp.getServerPort}")
   p.defProperty('id', 'ID for this oml client', "#{Experiment.ID}")
   p.defProperty('expId', 'ID for this experiment', "#{Experiment.ID}")

   p.defProperty('interface', 'Listen on this given interface')

    p.addApplication(:otl2, "otl2") {|otl|
      otl.bindProperty('oml-server', 'omlServer')
      otl.bindProperty('oml-id', 'id')
      otl.bindProperty('oml-exp-id', 'expId')
      otl.bindProperty('interface', 'interface')
}
}

defGroup('listener', [1,1]) {|node|
  node.prototype("listener", {
                'interface' => "pcapint:ath0"
  })
}

Do not hesitate to contact me if needed. I'll test it too this weekend 
once we update a couple of software at NICTA.

Regards,

Guillaume
