ORBIT-USER: Warning message when installing Click on specific node

[Kishore Ramachandran]

Hi Arinto:

You can use ANY traffic generator (iperf, nuttcp, netperf, OTG, D-ITG, etc)
on the VMs - use one of the VMs as the client and the other as the server.
The documentation only consists of click script installation because
everything else is not part of this emulation system. As I said earlier, you
can start with shell scripts and writing to text files to begin with. You
can use OML and other features once you get the basic results.

After you run the CreateMobilitySetup script and say that your VMs are
node1-2 and node1-4 (if IP addr: 192.168.1.4), you can run a shell script
with the following contents:

ssh root at node1-2 "/sbin/nuttcp -u -S >> /root/server.log"
ssh root at node1-4 "nuttcp -u -i1 -T60 192.168.1.4 >> /root/client.log"

This should give you two files which you can post process later. Note that
you will have to install nuttcp or your preferred traffic generator on the
image (if it is not already there).

regards,
Kishore
