Custom Experiment on InstaGENI with GEMINI

1. Goals

2. Experiment Overview

3. Setting up your user environment

Follow these instructions to configure Omni

Now we want to decrypt our private key so Omni won't have to repeatedly prompt for the key password.

4. Create the experiment slice

We will do this through Flack with InstaGENI AMs.

Now we do some editing of the request RSpec.



       <execute command='wget -q -P /tmp;sudo bash /tmp/' shell='sh'/>\n\

sed "/\/node\>/ i\ ${TEXT_ADD}" ${FILE}
$ ./ myslice.xml > myslice_phoebus.xml

First, renew the slice created in Flack via Omni.

Create the slivers at each AM. (ig-utah and/or ig-ky)

5. Instrument the slice

geni@GEC16-Tutorials:~/src/GEMINI/geminiv2$ ./ -n ezraslice2 -f ~/.ssl/geni_cert.pem
geni@GEC16-Tutorials:~/src/GEMINI/geminiv2$ ./ -n ezraslice2 -f ~/.ssl/geni_cert.pem

6. Login and configure experiment nodes

ssh to each of the nodes in the experiment. Become root with 'sudo su'.

We will now add host routes so the client nodes in the experiment can talk to each other across the GW systems.

On client0:

$ route add -net gw

On gateway0:

$ route add -net gw

On gateway1:

$ route add -net gw

On client1:

$ route ad -net gw

From client0, you should now be able to ping and traceroute to client1:

$ ping
PING ( 56(84) bytes of data.
64 bytes from icmp_req=1 ttl=62 time=0.054 ms
64 bytes from icmp_req=2 ttl=62 time=0.062 ms
64 bytes from icmp_req=3 ttl=62 time=0.067 ms
--- ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 1999ms
rtt min/avg/max/mdev = 0.054/0.061/0.067/0.005 ms
$ traceroute
traceroute to (, 30 hops max, 60 byte packets
 1  gateway0-lan0 (  0.049 ms  0.013 ms  0.011 ms
 2  gateway1-lan1 (  0.031 ms  0.017 ms  0.016 ms
 3 (  0.028 ms  0.022 ms  0.021 ms

7. Configure measurements

Login to the GENI Desktop using the bookmark in Firefox. link

Note that this step requires that you first login to your Slice Authority Emulab site.

8. Run experiments
