Orbit-Planet Lab Integration demo:

This demo illustrates an orbit node (acting as an AP) fetching a video stream from a remote planet lab node and feeding it to a client node. The basic steps involved in the demo are:-

→ Firstly, a key-pair has to be generated

ssh-keygen -t rsa

This will generate 2 files id_rsa and id_rsa.pub which hold the private and public keys resp.

→ Next the keys need to be transferred to the slice on the planet node. Winlab has a permenant slice orbit_pkamat.

ssh-copy-id -i ~/.ssh/id_rsa.pub orbit_pkamat@…

→ After logging into the grid console, you have to image the nodes with planetlab-biggrid.ndz (which resides in repository2:/export/orbit/image)

imageNodes [13,5],[13,7] planetlab-biggrid.ndz

Changes might be needed to the script file 'startitall.rb'. For this the nodes have to be powered up

wget -O - -q '​http://cmc:5012/cmc/on?x=13&y=5'

And then ssh the node to get access to its root

ssh root@node13-5

Then the script file can be modified accordingly.

→ The new version of the nodehandler script and the experiment script 'planetlab.rb' are to be downloaded from nodehandler-planetlabdemo.tar.gz

cd nodehandler/src/ruby ruby handler/nodeHandler.rb -k test:exp:planetlab

Changes might be needed to the script files 'nodehandler.rb' and 'planetlab.rb'.
